Abstract

A user-friendly method is provided for specifying WWW sites. When the user selects any symbol (e.g., word, phrase, sentence, figure and image) and copies it onto clipboard (81) while using an application running on a client computer (3), a resident linker (23) automatically reads the symbol from the clipboard (81) and sends it to a URL server (5). The URL server (5) refers to a database (15), which stores sets of symbols and the corresponding URLs, and supplies the linker (23) with a URL corresponding to the received symbol. A WWW browser (21) accesses the page in the URL and displays it.

Description

SPECIFICATION
A SYSTEM AND A PROCESS FOR SPECIFYING A LOCATION ON A NETWORK
TECHNICAL FIELD
The present invention pertains to art for using a computer network or communications network, and in particular to art for easily specifying a physical location or a logical location on such a network, such locations, for example, including uniform resource locators (hereinafter "URLs") and electronic mail (hereinafter "e-mail") addresses in the case of the Internet, telephone numbers in the case of a telephone network, and so forth.
BACKGROUND ART
There are a wide variety of services available on computer networks, such as, for example, the Internet or various intranets, wherein information is provided or information is transferred, such as in connection with those services and resources available via the World Wide Web (hereinafter "WWW"), e-mail, hle transfer protocol (hereinafter "FTP"), and the like. In using such services, it is necessary for a user to specify the location on the network of the source of any such information which is to be provided and the destination to which any such information is to be transferred.
For example, to access (as used here, "access" means to make a connection to a network location, e.g., a website, at which time a "home page," "index page,"
or the like may be returned by default to and opened by the computer that initiated the connection) and be able to see the contents of a particular website on the Internet using a WWW
browser-type application (as used herein, "application" is used synonymously with "application program"), the user must specify for the browser-type application (hereinafter "browser") the URL representing the address of that website. Furthermore, to place a telephone call from a computer, the user must specify for the application that will dial the telephone number (hereinafter "dialup application") the telephone number that is to be dialed (here and below, where we refer to "dialing" of a telephone number, this is meant in its most general sense of placing a telephone call, regardless of the purpose of the call, e.g.
voice, modem transmission, facsimile transmission, etc., and regardless of the method by which the call is placed, e.g. rotary-type pulses, touch-tone-type tones, etc.).
The most typical method for specifying a URL is to type in the URL from a keyboard. However, since URLs quite frequently consist of strings of more than ten, and often even more than twenty, characters, and since these character strings are moreover frequently such that they are not easily remembered by a human being, typing in a URL by hand is not at all an enjoyable: task for the average user. The same can be said of typing in a telephone number.
As one method for simplifying the specification of URLs, the URL listing capability of WWW browsers, referred to variously as "Bookmarks," "Favorites,"
or the like, is known. However, as the number of entries in such a list grows, not only does it become increasingly difficult to quickly select the desired entry from among the others in the list, but it also becomes increasingly difficult to determine which list entry corresponds to which website. Furthermore, this capability cannot be taken advantage of with respect to URLs not entered in such a list, and in order to enter a URL into such a list in the first place, a user must either type in the URL by hand, or if utilizing a link from another website must first access the LJRL of the other website.
Furthermore, it may h<rppen that while carrying out some task or the other at a particular application one wishes to obtain information pertaining to that task from a network. For example. while creating a document on the subject of intellectual property within a word-processing-type application (hereinafter "word processor") one may wish to visit the website of a government patent office to take advantage of resources or services offered by that patent office, or while creating a document on the subject of automobiles one may wish to visit the website of a particular automobile manufacturer to investigate the specifications of a particular type of automobile, and so forth. In such a case, a user must hrst stop what he is doing at the application he is currently using, and must then launch (as used here, "launch" means to cause execution of an application, or when the application has previously been executed and is currently running in background, as may be the case in multiple-program-loading-type or multitasking-type environments, may also by implication be taken to mean making an application running in background the active application) a WWW browser and specify the URL of the desired website. This represents quite an inconvenience to the user. The same is true with respect to dialing a telephone number.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 shows the overall constitution of one embodiment of a network location specification system according to the present invention.
Whereas in this embodiment a version of the present invention is described in terms of an example in which a URL is specified for use by a WWW browser on a computer utilizing the Internet, it will nonetheless be readily apparent to one of ordinary skill in the art upon a reading of the following description of the embodiment that the principles of the present invention are not limited to Internet URLs, but may also be applied to specification of a wide variety of different types of locations on a wide variety of different types of computer networks.
A system 1 shown in FIG. 1 comprises a plurality of client computers 3A, 3B ... capable of being connected to the Internet, and at least one URL server 5 capable of two-way communication with these client computers 3A, 3B, ... . Installed on each of the client computers 3A, 3B, ... is a WWW browser 21A, 21B, ... and a program resident in random-access memory (e.g., a terminate-and-stay-resident-type program) which shall be referred to as a "linker" 23A, 23B, ... . The URL server 5 typically exists at a location on the Internet, and typically communicates in two-way fashion with the client computers 3A, 3B, ... by means of, for example, hypertext transport protocol (hereinafter "HTTP"). The URL server 5 possesses a database 15, accumulated within which there are a multiplicity of symbols 11A, 11B, ... and a multiplicity of URLs 13A, 13B, ...
corresponding thereto and finked therewith (except where specifically indicated, the word "link" as used herein does not refer to and should not to be contused with hypertext "jumps" or "links" created using HyperText Markup Language HREF statements and the like).
As used here, "symbol" refers to a data representation (symbol) that is capable of being recognized by one or more of the human senses and remembered by a human being, and that is capable of being specified by a human being to a computer by way of a man-machine interface of that computer. While the most typical examples of such symbols include text data such as letters and other characters commonly capable of being handled by any of a wide a variety of applications such as desktop-publishing-type (herein after "DTP") and spreadsheet-type applications, examples of which include words, phrases, clauses, sentences, textual passages, and the like, such symbols are certainly not limited to text data, but may include vector graphic data such as may be capable of being handled by a draw-type graphics application, and bitmapped image data such as may be capable of being handled by a paint-type graphics application. Moreover, such a symbol may also comprise three-dimensional graphic data representing a solid object or objects such as may be capable of being handled by a three-dimensional graphics application. In addition, such symbols are not limited to those representations capable of being perceived by the sense of sight, but may include representations that are capable of being perceived auditorily, such as, for example, data capable of reproducing a melody or rhythm. It is desirable that the symbol represent some meaning or concept. Random numeric sequences and the like which tend not to evoke any concept or meaning in the mind of a human being are not suitable for use as such a symbol. Conversely, words, phrases, clauses, sentences, textual passages, trademarks, service marks, logotypes, advertising slogans, company names, personal names, designations, and the like are ideal for use as such symbols.
Geographical references, place names, street addresses, telephone numbers, and so forth are also suitable for use as such symbols.
Users at the client computers 3A, 3B, ... can specify arbitrary symbols to the linkers 23A, 23B, ... within the client computers 3A, 3B, ... . The linkers 23A, 23B, ... within the client computers 3A, 3B, ... transmit requests to the URL
server 5 to perform searches using the specified symbols 7A, 7B, ... as keywords (i.e., words which will be attempted to be found). Using the specified symbols 7A, 7B, ... as keywords, the URL server 5 searches the contents of a database 15 and retrieves therefrom URLs 9A, 9B, ... , which correspond to the symbols 7A, 7B, ... which were included within the search requests received from the client computers 3A, 3B, ... . The URL
server 5, moreover, returns the retrieved URLs 9A., 9B, ... to the linkers 23A, 23B, ...
within the client computers 3A, 3B, ... . Upon receiving the URLs 9A, 9B, ... which were returned from the URL server 5, the linkers 23A, 23B, ... within the client computers 3A, 3B, ... launch WWW browsers 21A, 21B, ... , passing thereto the URLs 9A, 9B, ... . The WWW browsers 21A, 21B, ... then access websites at the URLs 9A, 9B, ... .
As a result of the above operation, users at the client computers 3A, 3B, ...
are able to achieve the same effect by specification of symbols as would result from specification of URLs. For example, specification of the symbol "Japanese Patent Ofhee"
could be employed to effect accessing of the website of the Japanese Patent Ofhce. It is therefore only necessary that a user know the symbol for the website he ~.~.~ishes to visit, there being no need to know the URL thereof. Text, graphics, or like representations easily remembered by human beings may be set as symbols. For example, company names or trademarks, advertising slogans such as "conveniently located near such-and-such subway stop" or the like, pictures of logotypic animal personalities (mascot-like characters), and other such symbols easily remembered by the user may be set as symbols to represent websites of companies. Accordingly, it will in general be much easier for the user to specify such a symbol than to specify the corresponding URL. And even when using a list of the "Bookmarks" or "Favorites" variety, it will be much easier to hnd the desired entry from among the others in the list when the entry has been entered in the form of a symbol.
A plurality of symbols can be set to represent a single URL. For example, three different types of symbols-the company name, a pictorial figure, and a slogan-might be set to represent the website of a company. Conversely, the same symbol might be assigned to a plurality of URLs. For example, a name that is symbolic of a particular group of affiliated companies might be set to represent the URLs of a plurality of companies belonging to that group.
When searching for a symbol that comprises image; (including graphic) or sound data, art from the field of optical or acoustical pattern recognition can be employed to assist in determination of whether or not a match (hereinafter "hit") exists.

FIG. 2 shows an example of a display 31 at a man-machine interface of a client computer 3 during specification of a symbol by a user. Note that while the example shown in FIG. 2 incorporates a "Windows"-type environment such as is a feature of certain operating systems sold by Microsoft Corporation of Redmond, Washington, USA
(hereinafter simply "Windows" environment), from the description thereof it will be readily apparent to one of ordinary skill in the art how the equivalent effect might be achieved on different operating systems.
In FIG. 2, at the time shown, window-like subregions of the display (hereinafter "windows") 33, 35, 37 belonging to a number of applications which a user has already launched, including a WWW browser 21 and a word processor, are shown open on the desktop 39 at a display 31. A box-shaped area for acceptance of user input (hereinafter "edit box") 43 of a linker 23 is likewise open. There is also an icon-type representation (hereinafter "icon") 41 of the linker 23 on the desktop 39. There is a control button 47 for the linker 23 in a bar-shaped menu (hereinafter "task bar";I 45 at the edge of the display 31.
The user can enable or disable the linker 23, for example, by clicking or alternatively by double-clicking (i.e., using a mouse-type interface;
hereinafter "mouse") the linker control button 47 within the task bar 45. Only when the linker 23 is enabled is it possible to place a symbol in the linker 23 as a result of the procedure to be described below.
Here, let us take the case in which a user decides, during the course of, for example, creating a document using an arbitrary application, say a word processor, that he wants to access the website of the Japanese Patent Office. In such a case, if the words "Japanese Patent Office" 51, which we will in our example assume constitute a symbol for the Japanese Patent Office, happen to appear in the document the user is currently working on, the user might select these words using directional keys (hereinafter "arrow keys") on a keyboard, a mouse, and so forth, or he might select these words by typing in "Japanese Patent Office" 51 from a keyboard, but in any case we will assume that the selected words "Japanese Patent Office" S1 are now displayed in reverse video (i.e., "highlighted") on the display. Next, the user can employ whichever he prefers of a number of possible procedures such as, for example procedures (1) through (3) to be described below, to pass the selected words "Japanese Patent Office" 51 as a symbol to the linker 23.
(1) Copy the words ".Japanese Patent Office" 51 to a clipboard. This might be done, for example, by entering a key sequence such as, for example, Control+C
(the "+"
indicating that more than one key is to be held down simultaneously), or by, for example, clicking on a certain copy button 53 within a tool bar (a bar-shaped menu similar in concept to the task bar of the operating system) at the word processor window 35.

(2) Drag and drop (i.e., using a mouse) the words "Japanese Patent Office" 51 onto the icon 41 of the linker 23 as indicated by arrow 5~ in the drawing.

(3) Drag and drop so as to copy the words "Japanese Patent Otiice" 51 into the edit box 43 of the linker 23 as indicated by arrow 57 in the drawing, and then okay (i.e., finalize) selection of "Japanese Patent Office" 51 by pressing the RETURN key or the like.
Furthermore, note that it is also possible to select from among a list of linked candidates at this time; for example, in the event that the words "Japanese Patent" were dragged and dropped into the edit box 43 from the word processor, the words "Japanese Patent" might be changed to "Japanese Patent Otiice" at the edit box 43 by means of a simple prescribed key sequence prior to okaying selection thereof.
After carrying out one of the above procedures, or a procedure equivalent in effect thereto, the linker 23 receives the words "Japanese Patent Office" 51 and sends these words to the URL server 5 as described above, upon which these words are converted to "http://www.jpo-miti.go.jp/", the URL of the Japanese Patent Office's website, and a command to launch the WWW browser 21 is issued with this URL being passed thereto.
As a result, the URL of the Japanese Patent Office's website, "http://www.jpo-miti.go.jp/", has been specified for use by the WWW browser 21, the effect of which is that this URL, "http://www.jpo-miti.go.jp/" 61, and the Japanese Patent Office's home page 63, are displayed at the window 33 of the WWW browser 21.
Furthermore, as other methods of specifying a symbol for use by the linker 23, the symbol can be typed in directly at the linker edit box 43, or the symbol may be entered in place of the URL at the "Address:" or "Location:" or other such input Geld for entry of the site to be accessed, at the window 33 of the WWW browser, and so forth.
FIG. 3 shows the internal structure and function of a client computer 3 and a URL
server 5 for carrying out the aforementioned operations.
Within a client computer 3, a linker 23 monitors a clipboard 79, a memory area managed by the operating system, which may, for example, be "OS73," a product of Microsoft Corporation of Redmond, Washington, USA. When a certain symbol 75 is copied from a memory area of a certain application, say a word processor 71, to the clipboard 79 (arrow 77), the linker 23 captures the symbol 81 that is within that clipboard 79 (arrow 83). The linker 23 then looks in a cache file 87 which it possesses to see if the same symbol as the captured symbol 85 is contained therein. Stored within the cache file 87 are the n most recently handled sets of symbols 89A, 89B, ... and URLs 91A, 91B, ... that have been handled by the linker 23, where n is a prescribed number. If one of the symbols (e.g., 89B) within this cache tile 87 is found to be the same as the captured symbol 85, the linker 23 reads a URL 91B corresponding to that symbol 89B from the cache tile 87 (arrow 93), and passes this URL 95 which it has read to the WWW
browser 21 (arrow 97).
If there is no symbol within the cache file 87 that is found to be the same as the captured symbol 85, the linker 23 sends a search request to the URL server 5 with that symbol 85 to be used as search keyword (arrow 101). The URL server 5 searches a database 15 to see whether the same symbol as the received symbol 103 exists therein, and if it Ends such a symbol (e.g., 105B) it reads a URL 107B corresponding thereto from the database 15 (arrow 108), and returns this URL 109 which it has read to the linker 23 (arrow 111). The linker 23 passes the URL 95 received from the server 5 to the WWW

browser 21 (arrow 97). Furthermore, the linker 23 stores the symbol 85 it sent to the server 5 and the URL 95 it received ti-om the server 5 in its cache tile 87 such that the two are mutually linked therein (arrows 113 and 115).
Furthermore, in the case where a symbol 75 is passed to the linker by dragging and S dropping it thereon from a certain application, say a word processor 71, the situation will be as follows. While a symbol 75 within the memory area of the word processor 71 is being dragged, that symbol 75 remains under the management of the operating system, as indicated by the broken line 117 in the drawing. Then, if this symbol 75 which is b;;ing dragged is, for example, dropped onto the icon of the linker 23, the linker 23 will copy that symbol 75 into its own memory area, capturing it therein (arrow 119).
Processing after capture of the symbol is similar to the aforementioned case in which the symbol is captured From the clipboard 79.
In addition, the linker 23 also monitors typed input from the keyboard to see whether a symbol is entered in place of a URL at the "Address:" or "Location:"
or other such input field for entry of the site to be accessed by the WWW browser 21.
That is, the linker 23 monitors the route (arrow 123) by way of which a symbol entered from the keyboard 121 would be passed by the operating system to the WWW browser 21, capturing any such entered symbol therefrom (arrow 127). Moreover, determination of whether the typed text input is a symbol or a URL may be accomplished by, for example, evaluating whether the text in question matches the prescribed format of a URL, and assuming it is a URL if it does match that format and assuming it is a symbol if it does not.
Operations after capture of the symbol are similar to the corresponding operations described above.
FIG. 4 is flowchart showing processes occurring a2 a linker 23.
The linker 23 checks at regular intervals to see whether there is a symbol in the clipboard (S1). Furthermore, the linker 23 also checks, as described above, to see whether a symbol has been typed in at the "Address:" or "Location:" or other such input field for entry of the site to be accessed by the WWW browser 21 (S2). If the result of either check is a YES, the linker 23 captures that symbol, and then first searches its cache tile 87 to see whether the same symbol as the captured symbol is contained therein (S4).
Furthermore, in the event that the symbol has been passed to the linker 23 by dragging and dropping thereof From another application (S3), the linker 23 likewise proceeds to step S4.
At step S4, if the symbol in question is found in the cache tile 87, the linker 23 reads all URLs corresponding to that symbol from the cache file 87 (S5). Then, in the event that only one URL was read therefrom, the linker 23 issues a command to launch a WWW browser 21, passing this URL which was read to the WWW browser 21. In the event that a plurality of URLs were read ti-om the cache file 87, a list of this plurality of URLs which were read is displayed at the display of the man-machine interface (S7) so as to allow the user to choose one URL therefrom. Upon selection by the user of one URL
from that list (S8), the linker 23 proceeds to step S9 and passes that URL to the WWW
browser 21. In the event that the user does not select a URL from the list (e.g., the user selects "cancel" or the like), the linker 23 proceeds to step S10, to be described below.
At the aforementioned step S4, if the symbol in question is not found in the cache tile 87, the linker 23 sends a request to search for that symbol to the URL
server 5 (S10), and awaits the response of the URL server 5 and the results of the search performed thereat (S11). Upon receiving the response of the URL server 5 and the results of the search performed thereat, the linker 23, in the event that those search results contain only one URL, issues a command to launch a WWW browser 21, passing this URL to the WWW browser 21 (S 15). On the other hand, if those search results contain a plurality of URLs, a list of this plurality of URLs is displayed at the display of the man-machine interface (S14) so as to allow the user to choose one URL therefrom. Upon selection by the user of one URL from that list, the linker 23 proceeds to step S15 and passes that URL to the WWW browser 21. In the event that the user does not select a URL
from the list (e.g., the user selects "cancel" or the like), the linker 23 does nothing further and instead returns to the first step, step S1. Likewise, in the event that no URL
is contained in the response from the URL server 5, the linker 23 in this case also does nothing further and instead returns to the first step, step S1 (an error message to the effect that a site corresponding to the symbol in question was not found may also be displayed at this time).
When a URL is sent to the WWW browser 21 at step S15, the linker 23, in addition, writes the set comprising that symbol and that LJRL to its cache file 87 (S16), and returns to the first step, step Sl.
FIG. 5 is flowchart showing processes occurring at a URL server 5.
Upon receiving a request to search for a symbol from the linker 23 (S21), the URL
server 5 searches a database 15 for that symbol (S22), and if the symbol in question is found therein, reads from the database 15 all URLs corresponding thereto and returns these as search results to the linker 23 (S23). It the symbol is not found in the database 15, a response to the eltect that there were no "hits" (i.e., matches) is returned thereto instead (S23).
When there are a plurality of URLs corresponding to a single symbol, the URL
server 5 can, instead of returning that plurality of URLs to the linker 23, also proceed as follows. To wit, it can prepare in advance a single-page website containing a list of that plurality of URLs, with hypertext markup language (hereinafter "HTML") links to those URLs, and can set the URL of that URL list pate in correspondence to that symbol and store this in the database 15. Accordingly, the URL server 5 can then return the URL of this URL list page as results of the search for that symbol" As a result, because that URL
list page will then be displayed at the WWW browser 21, the user can easily "jump to"
(i.e., access) the desired URL from that page.
In the embodiment described above, the URL server 5, as shown in FIG. 3, only sends URLs 109 to the linker 23. However, as a variation on this embodiment, the URL
server 5 may send sets comprising symbols 103 and URLs 109 to the linker 23, in which case the linker 23 need only store in its cache file 87 the sets of symbols 103 and URLs 109 received from the URL server 5 (i.e., writing of the symbol 85 by the linker as indicated by arrow 113 in FIG. 3 becomes superfluous).

FIG. 6 shows a linker 123 associated with another embodiment of the present invention.
The linker 123 shown in FIG. 6 possesses a symbol selecting component 125 and a URL converting component 127 as executable modules. The symbol selecting component 125 possesses a symbol link web 129 comprising a variety of symbols 131A, 131 B, ... freely set and freely mutually linked by the user. The symbol selecting component 125 carries out processing for the purpose of allowing selection of a desired symbol as the user freely travels from link to link within the symbol link web 129.
Furthermore, the URL
converting component 127 receives symbols selected by the user from the symbol selecting component 125, and performs processing similar to that at step S4 and thereafter in FIG. 4.
FIG. 7 shows a sample display that might be displayed by the symbol selecting component 125 as the user is selecting symbols while traveling along the links of the symbol link web 129.
When the user passes, let us say, "SYMBOL A" to the linker 123 by copying via clipboard, dragging and dropping, or the like from a certain application, the symbol selecting component 125 of the linker 123 displays "SYMBOL. A" 141A as shown at display 151 at the left edge of FIG. 7. Next, if the user double-clicks on (i.e., to indicate approval and okay selection ot) this "SYMBOL A" 141A appearing at display 151, the symbol selecting component 1.25 passes "SYMBOL A" 141A to the URL converting component 127, and so "SYMBOL A" 141A is converted into a corresponding URL
143A and this is passed to a WWW browser.
On the other hand. it the user single-clicks on (i.e., to indicate he wants to look at other candidates linked via the symbol link web to) "SYMBOL A" 141A appearing at display 151, the symbol selecting component 125 accesses the symbol link web 129 and reads all of the symbols linked to "SYMBOL A" 141A, displaying these at display 153.
Accordingly, a list comprising "SYMBOL B" 141B, "SYMBOL E" 141E, and "SYMBOL
F" 141F are displayed at display 153. Upon double-clicking on, let us say, "SYMBOL F"
3() 141F in this list, this "SYMBOL F" 141F is converted into a corresponding URL

and this is passed to a WWW browser. However, if the user single-clicks on "SYMBOL
F" 141F, a list of the symbols linked to that "SYMBOL F" 141F; i.e., "SYMBOL
E"
141E, "SYMBOL B" 141B, and "SYMBOL D" 141D; are displayed at the display 155 that is displayed next.
The user can thus utilize a symbol link web 129 which he has constructed himself to find and select the desired symbol as he traverses the links among the symbols of the symbol link web 129. There are a ~.~ariety of conceivable uses to which this capability may be put.
One such use is to assist human memory. For example, let us suppose a user accesses the website of a certain mail-order house and hnds there a catalogue containing a shoulder bag in which he is interested, but which he decides not to buy right away. At that time, thinking that he might want to purchase the shoulder bag at some date in the future, he enters the name of the mail-order house and the phrase "shoulder bag" into the symbol link web 129 such that they are linked together therein. Upon so doing, should he decide at some later time that he really does want to buy the shoulder bag, even if he is unable to remember the name ot~ the mail-order house, because entry of the phrase "shoulder bag"
and the passing thereof to the linker will cause display of a list of symbols linked to the phrase "shoulder bag", he will be able to hnd the name of'the mail-order house in the list, and by double-clicking thereon he will once again be able to access the website of that mail-order house.
Or, another such use is to allow the user to customize symbols. That is, it could well be the case that the symbols allowed to be passed to a URL server are not symbols defined by individual users but symbols defined by the URL server. In such a case, in the event that an individual user does not care for the symbols that happen to have been defined for him by the URL server, he may instead wish to use symbols that he himself has defined. To do this, he enters a symbol that he himself has defined and a symbol that has been defined by the URL server into the symbol link web 129 such that they are linked together therein, as a result of which it will then be possible for him to use the symbol that he himself has defined.
FIG. 8 is flowchart showing processes occurring at a symbol selecting component 125.
The symbol selecting component 125 first acquires a symbol at steps S1, S2, or S3 in FIG. 4 (S31), and the acquired symbol is displayed (S32). If the user then single-clicks on the displayed symbol (S33), the symbol selecting component 125 searches the symbol link web 129 for other symbols linked to that symbol (S34), and displays any symbol or symbols retrieved therefrom (i.e., displaying a list in the event that there is more than one) (S32). On the other hand, if the user double-clicks on the displayed symbol (S33), the symbol selecting component 125 passes that symbol to the URL
converting component 127 (S35).
FIG. 9 and FIG. 10 show two other embodiments wherein a character string entered by a user is passed to a linker as a symbol.
In these embodiments, a character string entered by a user from a keyboard is passed to a linker by way of an input method editor (hereinafter "IME"), a type of program module that functions as an intermediary, carrying out conversion of the character string entered by the user when necessary (e.g., in the case of entry of Japanese-language characters, by carrying out conversion from hiragana or katakana syllabary characters to kanji ideograms) before passing it to an application. In particular, a client computer in the embodiment shown in FIG. 9 possesses a linker IME 201 that is specially designed for the linker 209. On the other hand, in the embodiment chown in FIG. 10, a client computer possesses a linker IME 221 comprising IME modules 231, 235, similar in function to corresponding elements in a conventional IME, but with, in addition, a character string determining component 233 that has been incorporated therein for use with the linker. Whereas the embodiment of FIG. 9 is suitable for handling single-byte encoded characters (e.g., ASC.'II-encoded text characters, etc.), the embodiment of FIG.
10 is suitable for handling double-byte encoded characters (e.g., JIS-encoded text characters, JIS being a character encoding scheme similar in concept to ASCII, but using double-byte encoding instead of single-byte encoding so as to accommodate the larger character set required for the Japanese language).
In the embodiment shown at FIG. 9, the linker IME 201 possesses a character string determining component 213 and a buffer 211, wherein character strings are stored prior to and during ec>nversion. When the user presses a key or key sequence at a keyboard 205, the character (here and below, "character" is used in its most generic sense and should be understood to include alphanumeric characters as well as symbols, etc.) or command mapped to the pressed key or key sequence, as determined by the IME
specifications of the operating system, is input to the character string determining component 213 of the linker 1ME 201 by way of a keyboard driver 203. The character string determining component 213 then performs the following operations in response to the input character or command.
(1) In the event that <~n ordinary alphanumeric, symbol, or like character key is pressed:
The character string determining component 213 appends the character input by the pressing of an ordinary alphanumeric, symbol, or like character key to the contents of the buffer, and at the same time forwards this character tc.~ the currently active application 207 (e.g., word processor or spreadsheet software, etc.) such that it is displayed there underlined, in reverse video, shaded, blinking, in a distinctive color, or the like. As a result, the input character is displayed in temporary fashion at the application 207.
(2) In the event that the ESC key is pressed:
In response to the command from the ESC key, the character string determining component 213 clears the buffer 211 (i.e., erases the contents thereof) if it contains any character or characters, and at the same time terminates display of any character or characters currently being displayed in temporary fashion {and therefore underlined, in reverse video, shaded, blinking, in a distinctive color, or the like) at the application 207 (i.e., input of temporarily displayed characters is canceled). If the buffer 211 was empty, the character string determining component 213 instead performs the function assigned to the BACKSPACE key in the application 207 in question.
(3) In the event that the OKAY key (e.g., the ENTER key) is pressed:
In response to the command from the OKAY key., the character string determining component 213, if the buffer 211 contains any character or characters, terminates display of any character or characters currently being displayed in temporary fashion at the application 207, and then copies the contents of the buffer 211 to the application 207 and clears the buffer 211 (i.e., simple input of character or characters to the application 207).

(4) In the event that the LINK key (this may be defined in software as, for example, the Alt+L key sequence, or a special LINK key may be provided on the keyboard) is pressed:
In response to the command from the LINK key, the character string determining component 213 copies the contents of the buffer 211 to the linker 209 and clears the buffer 211, upon which the linker 209 carries out operations wherein the received characters are converted to URLs, Internet access is made possible, and so forth, as has already been described.

(5) In the event that the LINK and OKAY keys are pressed:
In response to the commands from the LINK and OKAY keys, the character string determining component 213, it the buffer 211 contains any character or characters, terminates display of any char<zeter or characters currently being displayed in temporary Fashion at the application 207, and then copies the contents of the buffer 211 to the application 207 and in addition copies the contents of the buffer 211 to the linker 209, and clears the buffer 211 (i.e., both functions, simple input of character or characters to the application 207 and operation of the linker 209, occur together).
In the embodiment shown at FIG. 10, the linker IME 221, in addition to being equipped with an IME core 235 and a buffer 231, these being similar in function to corresponding elements in a conventional IME, possesses a character string determining component 233 that has been specially designed for use with the linker 209.
When the user presses a key or key sequence at a keyboard 205, the character or command mapped to the pressed key, as determined by the IME specifications of the operating system, is input to the character string determining component 233 of the linker IME 221 by way of a keyboard driver 203. The character string determining component 233 passes the character or command to the IME core 235 for processing, while it at the same time monitors for recognition of any assigned key input that would cause launching of the linker 209 (e.g., the LINK key), and if such key input is recognized, regardless of whether such recognition occurs prior to conversion or during conversion, the contents of the butter 231 are immediately passed to the linker 209. When a key or key sequence other than a key or key sequence assigned to launch the linker 209 is pressed, the character string determining component 233 merely passes the input character or command to the IME core 235 for processing, in which case operation of the linker IME 221 will therefore be substantially the same as operation of a conventional IME. Taking input of Japanese characters as a specific example, operation of the character string determining component 233 is as described below.
(1) In the event that an ordinary alphanumeric, symbol, or like character key is pressed:
The character string determining component 233 passes the input character to the IME core 235 for processing. At the IME core 235, when keyboard input is set for romaji (a system of transliterating Japanese hiragana and katakana syllabary characters into roman, or standard alphabetic, letters) input, the character string is automatically converted to hiragana or katakana characters, as the case may be, based on the combination of entered alphabetic characters, and the converted hiragana or katakana character or characters are appended to the contents of the buffer 231, and at the same time these hiragana or katakana characters are forwarded to the currently active application 207 such that they are displayed there underlined, in reverse video, shaded, blinking, in a distinctive color, or the like. As a result, the input character or characters are displayed in temporary fashion at the application 207.

(2) In the event that the OKAY key (e.g., the ENTER key) is pressed:
The character string determining component 233 passes the command from the OKAY key to the IME core 235 for processing. The IME core 235 consults its internal kanji ideogram dictionary, obtains therefrom a candidate character string or strings into which the character string within the butter 231 might be converted, and overwrites the contents of the buffer 231 with these. At the same time, the IME core 235 forwards these same candidate character strings to the currently active application 207 such that they are displayed there underlined, in reverse video, shaded, blinking, in a distinctive color, or the like. As a result, the candidate; character strings are displayed in temporary fashion at the application 207.
(3) In the event that the ESC key is pressed:
The character string determining component 233 passes the command from the ESC key to the IME core 235 for processing. The IME core 235 carries out operations similar to those carried out by the character string determining component 213 shown in FIG. 9. Note, however, that some conventional IMEs may, upon receipt of a command from the ESC key, cancel the conversion candidates within the buffer 231 and instead go back to display of the original hiragana or katakana characters.
(4) In the event that the LINK key (this may be defined in software as, for example, the Alt+L key sequence, or a special LINK key may be provided on the keyboard) is pressed:
In response to the command from the LINK key, the character string determining component 233 copies the contents of the butter 231 to the linker 209 and clears the buffer 211, upon which the linker 209 carries out operations wherein the received characters are converted to URLs, Internet access is made possible, and so forth, as has already been described.
(5) In the event that the LINK and OKAY keys are pressed:

The character string determining component 233 passes the command from the OKAY key to the IME core 235 for processing; and at the same time, in response to the command from the LINK key, copies the contents of the buffer 231 to the linker 209.
Below, we describe concrete examples of methodologies for representation of character strings being entered into a linker employing an IME as described above.
1. Methodologies for representing selected character strings Taking the example of a "Windows" environment, the possible methodologies for representing selected character strings, i.e. for indicating that a character string is ready to be passed to the linker, during use of an IME can be broadly divided into two categories, as follows.
<1> Highlighting the selected character string using reverse video or the like <2> Underlining the selected character string using a solid line or a dashed line In the specific examples presented below, entered characters are enclosed in quotation marks "", and the portions thereof that are currently selected (i.e., that would be highlighted or underlined on the display) are enclosed in square brackets ~).
2. Procedure for entering single-byte encoded characters as at the embodiment shown in FIG. 9 2-1. Launching the linker directly from the desktop (i.e., not indirectly from some other application) <1> The linker IME is loaded into random-access memory (hereinafter "RAM") This may be accomplished as a result of its having been loaded as a terminate-and-stay-resident-type (hereinafter "TSR") program, or as a result of its having previously been launched in a multitasking environment, etc., but in this example we will assume that it has been loaded as a TSR program. (Of course, the functionality of the linker may also be written into the operating system code, or it may be incorporated into hardware or firmware; what matters is that it is active.) If this has been done, under the current specifications of the Japanese version of "Windows" the icon of the linker IME
will be displayed together with the icons of any other TSR programs in an area called the task tray, which is located in the lower right corner of the display (near the time display).
<2> With the cursor at any location on the display that will allow entry of typed input, type in the character string to be passed to the linker.
Example 1) "[SOFMAP]"
<3> After entering the text shown above, press Alt+Z or an equivalent key sequence assigned to represent the LINK key. Alternatively, the mouse can be used to select the icon of the linker. 'Ifie linker launches with the selected character string being passed thereto, this character string is converted to a URL, a browser is launched with this URL being passed thereto, and the website at that URL is accessed. If the LINK
key possesses the additional function of okaying the character string, okaying of the character string can be carried out simultaneously.
Example 1-1): When the LINK key only possesses the function of launching the linker "[SOFMAP]"
Result: The SOFMAP website is accessed.
Example 1-2): When the LINK key also functions as an OKAY key "SOFMAP"
Result: The SOFMAP website is accessed.
2-2. Launching the linker while entering text at a word processor or other application <1> Again, we take the case where the linker IME is loaded into RAM as a TSR
program. If this has been done, under the current specifications of the Japanese version of "Windows" the icon of the linker IME will be displayed together with the icons of any other TSR programs in an area called the task tray, which is located in the lower right corner of the display.

<2> Type in characters as you normally would. At this time, all characters in the entered string will be selected.
Example) "[The company]"
<3> Immediately prior to reaching the character string to be passed to the linker, press the ENTER key to okay the text typed in up to that point.
Example) "[The company is ~"
(Press the ENTER key) "The company is "
<4> Type in the character string to be passed to the linker.
Example 2) "The company is [SOFMAP]"
<5> Alter entering the: text shown above, press Alt+Z or an equivalent key sequence assigned to represent the LINK key. Alternatively, the mouse can be used to select the icon of the linker. The linker launches with the selected character string being passed thereto, this character string is converted to a URL, a browser is launched with this URL being passed thereto, and the website at that URL is accessed. If the LINK
key possesses the additional function of okaying the character string, okaying of the character string can be carried out simultaneously.
Example 2-1): When the LINK key only possesses the function of launching the linker "The company is [SOFMAP]"
Result: The SOFMAP website is accessed.
Example 2-2): When the LINK key also functions as an OKAY key "The company is SOFMAP"
Result: The SOFMAP website is accessed.

3. Procedure for entering double-byte encoded characters as at the embodiment shown in FIG. 10 <1> Again, we take the case where the linker IME (equivalent to a front end processor; hereinafter "FEP") is loaded into RAM as a TSR program. If this has been done, under the current specifications of the Japanese version of "Windows"
the icon of the linker IME will be displayed together with the: icons of any other TSR
programs in an area called the task tray, which is located in the lower right corner of the display.
<2> With the cursor at any location on the display that will allow entry of typed input, type in the character string to be passed to the linker. Upon so doing, the FEP
functions so as to automatically convert alphabetic characters to hiragana (or katakana) characters, displaying these as it does so.
Example 3) Character entry and display thereof are as shown at FIG. 17.
<3> After entering the text indicated, press Alt+Z or an equivalent key sequence assigned to represent the LINK key. Alternatively, the mouse can be used to select the icon of the linker. In either case, the linker launches with the selected character string being passed thereto, this character string is converted to a URL, a browser is launched with this URL being passed thereto, and the website at that URL is accessed.
If the LINK
key possesses the additional function of okaying the character string, okaying of the character string can be carried out simultaneously.
Example 3-1): When the LINK key only possesses the function of launching the linker Character entry and display thereof are as shown at FIG. 18.
Result: The Sotinap Future Design website is accessed if such a website exists.
Example 3-2): When the LINK key also functions as an OKAY key Character entry and display thereof are as shown at FIG. 19.
Result: The Solinap Future Design website is accessed if such a website exists.

<4> In the event that no URL is assigned to the hiragana/katakana syllabary character string shown at FICA. 20, the user presses the SPACE key or an equivalent key sequence assigned to represent syllabary-ideogram conversion, causing the FEP
to carry out conversion between hiragana/katakana syllabary characters and kanji ideogram characters. During the process of syllabary-ideogram character conversion, the user can cause any number of permutations of alternative conversion candidates to be displayed until he obtains the desired character string.
Example 4) Character entry and display thereof are as shown at FIG. 21.
, (Press the SPACE key) Character entry and display thereof are as shown at FIG. 22.
(Press the SPACE key) Character entry and display thereof are as shown at FIG. 23.
(As shown, long character strings may be automatically broken up into a number of conversion candidates by the FEP.) <5> When the character string you want to select (e.g., the character string shown at FIG. 24) is displayed as a conversion candidate, press Alt+Z or an equivalent key sequence assigned to represent the LINK key. Alternatively, the mouse can be used to select the icon of the linker. In either case, the linker launches with the selected conversion candidate character string being passed thereto, this character string is converted to a URL, a browser is launched with this URL being passed thereto, and the website at that URL is accessed. If the LINK key possesses the additional function of okaying the character string, okaying of the character string can be carried out simultaneously.

Result: The Sotmap Future Design website is accessed if such a website exists.
3-1. Launching the linker while entering text at a word processor or other application <1> Again, we take the case where the linker IME (FEP) is loaded into RAM as a TSR program. If this has been done, under the current specifications of the Japanese version of "Windows" the icon of the linker IME will be displayed together with the icons of any other TSR programs in an area called the task tray, which is located in the lower right corner of the display.
<2> Type in characters as you normally would. At this time, the FEP will operate so as to automatically convert all characters in the entered string to hiragana (or katakana) syllabary characters, selecting (i.e., highlighting, etc.) them as they are displayed.
Example 5) Character entry and display thereof are as shown at FIG. 27.
<3> Create text as usual using the syllabary-ideogram conversion capability of the FEP, converting some entered characters to kanji ideogram characters and some entered characters to hiragana syllabary characters, as the case may be. Immediately prior to reaching the character string to be passed to the linker, press the ENTER key to okay the text typed in up to that point.

FIG. 11 shOWS yet another embodiment of a linker.
The linker 301 resides on a client computer and possesses a telephone word lookup table 303 and a text-action lookup table 305. Stored within the telephone word lookup table 303 are a plurality of keywords of the sort that might typically be employed to indicate telephone numbers. Stored within the text-action lookup table 305 are various text strings (in the example shown in the drawing, "soiina,p", "cd", "letter", "Mary", etc.) together with actions that are linked thereto (in the drawing, these links are indicated by equal signs). Here, "actions" specify tasks to be executed by the client computer. For example, in the example shown at FIG. 11, a URL such as "http://...." is an action specifying that the website indicated by that URL should be accessed, the name of a file containing an executable program such as "CDplayer.EXF;" is an action specifying that the program in question should be executed, the name of a data file (as used here, a "data" file is any non-executable file, this term not being meant to exclude tiles containing ASCII or other such data representations of text) such as "LetterHead.DOC" is an action specifying that the data file in question should be opened, and a telephone number such as "te1031234567" is an action specifying that the telephone number in question should be dialed.
In addition to the linker 301, there are also a number of tiles 311, 313, 315, 317, 319 at the client computer. In the example shown at FIG. 11, tile 311 is a dialup application for dialing a telephone number, file 313 is a WWW browser, file 315 is an application for playing an audiu compact disc (hereinafter "audio CD") that has been loaded into the client computer's CD-ROM drive, file 317 is a word processor, and tile 319 is a document (file containing data representing text) capable of being opened by a word processor; however, these are merely presented as examples, it being possible for these tiles to, in general, be any type of tile at all.
The linker 301 possesses two operational modes, network mode and local mode, between which it is capable of being switched by the user. In either mode, the linker 301 captures a symbol (typically a character string) in the same manner as was described above at the several embodiments. When network mode is selected, the linker 301, as was the case in the above embodiments, sends the aforesaid captured symbol to a URL
server (reference number 5 at FIG. 1), receives a corresponding URL from the URL
server, specifies that URL for use by a WWW browser 313 which it then launches, and the WWW
browser 313 accesses the website at that CIRL. On the other hand, in local mode, the linker 301 looks to sec whether the aforesaid captured symbol is contained in the text-action lookup table 305, and it a match is Found, an action corresponding to that text is read therefrom, and a program for executing the task specified by that action is launched so as to cause execution of the action in question.
Moreover, independent of the network-local mode selection described above, the linker 301 can be set to a telephone mode. In this telephone mode, the linker 301, in the event that the aforesaid captured symbol is a text string, uses the telephone word lookup table 303 to determine whether that character string contains a known telephone number.
If the character string contains such a telephone number, the linker 301 automatically extracts that telephone number from the character string and specifies that telephone number for use by a dialup application 311 which it then launches, and the dialup application 311 dials the telephone number in question.
FIG. 12 is flowchart showing processes occurring at the linker 301 when in telephone mode.
Upon capturing a character string symbol (S51), the linker 301 compares that character string with each keyword in the telephone word lookup table 303 (S52). If the character string contains a m.~rd that matches any of the keywords ("Yes" at S53), this indicates that there is a high probability that the character string contains a telephone number. In such a case, the linker 30'1 extracts a telephone number from the character string (S54) and specifies that telephone number for use by a dialup application 311 which it then launches, and the telephone number in question is dialed (S55). It is also possible to omit steps S52 and S53 and proceed directly to step S54 from step S51.
In parallel with the aforementioned processing for dialing of the telephone number, the linker 301 also carries out the processing indicated at step S56 and thereafter. To wit, the linker 301, if set to local mode ("Local" at 556), compares the captured character string with text in the text-action lookup table 305 (S57). If the character string matches any text in the text-action lookup table 305 ("Yes" at SS$), the linker 301 carries out processing for execution of the task specified by the action linked to the matched text in the text-action lookup table 305 (559). For example, referring to the example shown in FIG. 11, if the matched text is "sotinap", then because the action linked to the text "sotmap" is the URL "http://....", the linker 301 specifies the URL
"http://...." for use by a WWW browser 313 which it then launches, as a result of which the website at that URL is accessed. If the matched text is "cd", then because the action that is linked to the text "cd"
is the executable program tile "CDplayer.EXE" for playing an audio CD, the linker 301 launches CDplayer.EXE 315, as a result of which playing of audio CDs is permitted. If the matched text is "letter", then because the action linked to the text "letter"
is the document file "LetterHead.DOC", which is capable of being opened by a word processor 317, the linker 301 specifies the document tile "LetterHead.DOC" for use by the word processor 317 which it then launches, as a result of which the document file is opened.
If the matched text is "Mary", then because the action linked to the text "Mary" is the telephone number "te1031234567", the linker 301 specifies the telephone number "031234567" for use by a dialup application 31 I which it then launches, as a result of which that telephone number is dialed.

On the other hand, the linker 301, if set to network mode ("Network" at S56), sends the captured character string to a URL server, receives a corresponding URL from the URL server, and specifies that URL for use by a WWW browser 313 which it then launches (S60).
FIG. 13 shows a sequence of steps that might be used to extract a telephone number at step S54 of FIG. 12.
The linker 301 first extracts from the captured character string any pure or mixed numeric string, "mixed" here meaning that the initially extracted numeric string may in addition contain certain non-numeric formatting typical of telephone numbers.
That is, the initially extracted numeric string may be a pure, continuous numeric string, such as "12345678", or it may contain certain non-numeric formatting typical of telephone numbers. Included among such non-numeric formatting typical of telephone numbers are, tbr example, hyphens which may be used to separate sets of numbers, such as is the case in "1-234-5678"; parentheses which may surround a portion of an otherwise numeric string, such as is the case with "1(234)5678"; and so forth. Regardless of whether the initially extracted numeric string contains, in addition, such non-numeric characters, a pure numeric string is subsequently extracted therefrom (S61). The linker 301 then counts the number of digits in the numeric string to determine whether the number of digits falls within a prescribed range recognized as suitable for a telephone number (S62).
For example, a numeric string containing only one or two digits is probably too short, and a numeric string containing more than 20 digits is probably too long. Only if the number of digits contained in the numeric string falls within the prescribed range therefor does the linker 301 treat that numeric string as a telephone number (S63), and proceed to step S55 of FIG. 12, described above.
The above-described sequence of steps for extracting a telephone number is merely an example, there being a wide variety of conceivable algorithms according to which a telephone number may be extracted.

In the embodiments described above, where a linker handles a character string symbol, the character string is fundamentally represented by a character code.
However, even when a character string is represented by a bitmapped font image or an outline font image, by employing pattern recognition (e.g., optical character recognition;
hereinafter "OCR") art to convert that font image into a character code, it is possible for a linker to handle such a character string in the same manner as has been described in the above embodiments. For example, a user can use a region selecting tool in an image processing application to select a region corresponding to a desired character string from a text image scanned in using an image sc<~nner or from a photographic image downloaded from a digital camera, and use the Control+C key sequence or a similar operation to pass the bitmapped image in the selected region to the linker. Alternatively, the linker may also be constituted such that after using the mouse to point to or select an arbitrary icon, tool, or the like displayed on the display screen and carrying out a prescribed linker operation, a bitmapped-image character string containing a bitmapped image of the icon, tool, or the like is passed to the linker. Upon receiving the character string image, the linker carries out pattern recognition (e.g., OCR) and okays (i.e., finalizes) selection of character code for each letter in the character string. After the character string image has thus been converted to a character code string, it is then possible for the linker to carry out processing for accessing a website at a URL corresponding to that character string, for dialing a telephone number contained within that character string, or for executing an action corresponding to that character string, as has already been described in the above embodiments.
FIG. 14 shows yet another embodiment of a linker.
A linker 401 on a client computer is constituted from two different program modules: a core linker 415 and an Internet linker 419. The core linker 415 may be a TSR-type program. FIG. 15 is a flowchart showing the sequence of operations carried out by the core linker 415, and FIG. 16 is a flowchart showing the sequence of operations carried out by the Internet linker 419.

Below, we describe operation of the core linker 415 and the Internet linker with reference to FIG. 14 through FIG. 16.
The core linker 415 has two operational modes between which the user can choose, these being "network" and "local." In either mode, the core linker 415 employs a method, such as one of the various methods already described, to capture a symbol entered or selected by the user at an application on a client computer 401 (step S71 at FIG. 15). As an example, FIG. 14 shows a symbol 431 entered or selected by a user at a word processor 405 being captured by the core linker 415, as indicated by arrow 433. The operation that will next be carried out by the core linker 415 branches into two paths depending on the currently selected mode (S72). We will hrst describe the sequence of operations occurring in network mode.
In network mode, the core linker 415 launches the Internet linker 419, passing the captured symbol 435 thereto (S73 in FIG. 15), as indicated by arrow 437 in FIG. 14. The core linker 415 then goes into standby mode and awaits a new symbol. If the user enters or selects a new symbol, the core linker 415 captures the new symbol (S71 at FIG. 15), and then goes back and repeats the aforementioned operational sequence.
The Internet linker 419 is launched by the core linker 415 and receives the symbol from the core linker 415. The Internet linker 419 then creates a search request 441 requesting that a URL server 403 search its database 425 for that symbol (S81 at FIG.
16). The Internet linker 419 then launches a WWW browser 413 if one is not already launched on the client computer 401 (S82 and S83 at FIG. 16), and passes the of the URL server 403, which has been previously registered therewith, and the aforesaid symbol search request 441 to this WWW browser 413 (S84 at FIG. 16), as indicated by arrow 443. Operation of the Internet linker 419 thereafter terminates.
The WWW browser 413 employs the URL of the URL server 403, which it received from the Internet linker 419, to access the URL server 403, and passes the symbol search request 445, which it received from the Internet linker 419, to the URL
server 403, as indicated by arrow 447. The URL server 403 employs the symbol search request 445 which it has received to search the database 425 of the URL server 403 for the requested symbol, and if a match is found, reads trorn the database 425 the URL (or URLs) linked thereto (or the set comprising the symbol and the URL) and returns these to the WWW browser 413, as indicated by arrow 449. As a result, the WWW browser accesses the website at the URL corresponding to the symbol in question.
We will next describe operations in local mode.
In local mode, upon capturing a symbol 435, the core linker 415 searches for the captured symbol 435 within a local database 417 previously prepared within a client computer 401 (S75 at FIG. 1.5). Within the local database 417 are various symbols 421A, 4218, 421C, 421D, ... , and the various actions 423A, 4238, 423C, 423D, ...
linked thereto. Here, "action" refers to a task to be executed by the client computer when a certain symbol is specified by a user. For example, an action may be the name of a file (including the directory thereat) containing a program to be executed, the name of a data file (including the directory thereof) to be opened, a telephone number to be dialed, a URL
to be accessed, an e-mail address to which e-mail i5 to be sent, and so forth.
In the example shown at FIG. 14, the action linked to symbol 421A is the name of a certain file 423A that can be opened by a spreadsheet application 407, the action linked to symbol 4218 is the name of a certain image file 4238, the action linked to symbol 421C is a certain telephone number 423C, and the action linked to symbol 421D is a certain URL
423D.
The core linker 415 searches the local database 417 for the captured symbol 435, and if a match is found ("Yes" at S76 in FIG. 15), reads from the local database 417 the action (or actions) linked to that symbol 435, and executes the task indicated by that action (S77 at FIG. 15). For example, in the example shown at FIG. 14, if a match to Symbol 421A is found, a spreadsheet application 407 is launched, the name of the spreadsheet data file 423A is passed thereto, and that spreadsheet data file is opened, as indicated by arrow 451; if a match to symbol 4218 is found, a graphics application 409 is launched, the name of the graphics file 4238 is passed thereto, and that graphics file is opened, as indicated by arrow 453; it a match to symbol 421C is found, a dialup application 411 is launched, the telephone number 423C is passed thereto, and that telephone number is dialed, as indicated by arrow 455; and if a match to symbol 421 D is found, a WWW browser 413 is launched, the URL 423D is passed thereto, and that website is accessed, as indicated by arrow 457.
Whereas the above embodiments possess the two operational modes "network"
and "local," as a variation thereof it is also possible to have an embodiment wherein there is only one or the other of the two modes.
Whereas several embodiments of the present invention have, been described above, these embodiments are intended only for the purpose of example, it not being intended that the present invention should be construed as limited to these embodiments alone.
Accordingly, the present invention may be carried out in the context of a wide variety of embodiments other than those specifically presented herein. For example, in addition to Internet URLs, it is possible to apply the present invention to a wide variety of other types of network locations and resources.
