Description

RECORD REVIEW SYSTEM AND METHOD

Technical Field

The present invention relates to a system and method for facilitating review of a plurality of records, and, particularly, but not exclusively to a system and method foτ facilitating review of records obtained via a search.

Background to the Invention

Computer systems provide a convenient interface by which many records may be presented to a user for review. For example, documents, audio eta, may be provided over the Internet to a user for presentation to the user.

Computer systems maybe used to provide the results of searches of records to a user so that the user can review the records. For example, documentary searches, such as searches of patents and patent applications, may be presented to a user for a review via a computer interface.

The task of reviewing searches, particularly searches with large numbers of records, however, can still be very arduous, despite the convenience of a computing interface.

It is known to provide the results of patent searches, for example, via computer to a searcher (or other user) for review. Present computer interface search systems, however, provide little or no assistance to facilitate review by more than one person, for example in a collaborative context. There is presently no alternative but for one or more users to review the records separately.

Summary of the Invention

In accordance with a first aspect, the present invention provides a system for facilitating review of a plurality of records, comprising: a user interface arranged to have allocated to it a plurality of records for access for review via the user interface, and arranged to have a user assigned permission to access the user interface, and attribute allocation means arranged to enable the assigned user to apply an attribute against one or more of the plurality of allocated records, ϊa an embodiment, the user interface is arranged to have allocated to it a plurality of users assigned with permission to access the user interface. In this embodiment, the attribute allocation means is arranged to enable each of the assigned users to apply an attribute against one or more of the plurality of allocated records.

In an embodiment, the plurality of records are obtained from a search of one or more record databases.

In an embodiment, the plurality of records are obtained from a plurality of searches.

In an embodiment, the records are documentary records. In an embodiment, the records are patent records obtained from one or more patent searches.

Li the context of this specification, the terms "record" and "document" encompass any information item and may include text, images, sounds and video or any combination thereof. The records may be represented to a user as an icon in the user interface, but the invention is not limited to this form of representation, and may equally include, for example, thumbnails, text, sounds and the like.

In an embodiment, the system further comprises an indicator means arranged to enable application of an indicator providing identification of the user(s) who have applied the attributes. Applied attributes and their respective associated user(s) can therefore be ascertained, in order to facilitate the review.

The indicator of the user who applied the attribute may be itt the form of text, images, sounds or the like. Further, the indicator may provide information to identify a particular user (such as a person's name) or an attribute of that person Such as the organisation that the user represents, their age grouping, or geographical location.

In an embodiment, the user interface further comprises a workspace including, in one form, a plurality of computer accessible screens, by which the records can be displayed and to which the attributes and user indicators can be applied. The workspace therefore facilitates the review of τecords by allowing users to consider and apply attributes against individual ones of those records together with an indication of the user.

According to this embodiment, a number of significant advantages are achieved. Users of the workspace can readily establish which records are yet to be considered simply by inspecting for applied attributes, Further, the workspace allows for a more coordinated review process by multiple users through the application of the indicator of the user(s) who apply the attributes. On completion of the review process, the workspace can be reviewed to determine attributes applied by tibe users and to apply the attributes, to facilitate the review process.

The attribute applied to the records in the workspace may vary jn form depending on the purpose of the review. For example, the attribute might take the form of a measure of record relevance. In this form, the workspace may allow records to be filtered or ranked in the workspace according to their relevancy, allowing for a more considered approach to the review process. In another form, the attribute may comprise a commentary input by an allocated user. The commentary may, for example, be a critique on a particular part of the record.

The attribute may be applied to the record using many different methods. These may include the user selecting from a plurality of pre-set values, for example a selection of radio buttons implementing a measure of record relevancy. In another form the attribute may be entered as free text in a comments box associated with the record. In an alternative form, the attribute may be applied through placement of a representation of 1he record (e.g. in the form of an icon) in a particular position of the workspace.

In an embodiment, the system further comprises an administration means comprising assigning means, for assigning users to the user interface. This enables an administrator to assign users permission to access the user interface.

In an embodiment, the administration means further comprising an administration, interface.

In an embodiment, the administration means may also enable allocation of a ^• user type. This enables an additional level of granularity to the review process as it allows the users to be classed by their type. This feature may in turn allow better control over the review process. For example, in one embodiment it may be a requirement that at least one user of a particular user type apply an attribute to each record. An alert signal may be provided until this criteria has been met.

In an embodiment, the user interface allows for allocation of a plurality of hierarchical levels and the attribute allocation means may enable one or more users to apply attributes within the plurality of hierarchical levels. For example, in an embodiment, records fall within the "record" hierarchical level, and a user is enabled to apply attributes within the record hierarchical level (e.g. apply attributes to each individual record). The records may have been located by a particular search, for example a search of patent records. In this example, the search is allocated a higher hierarchical level, the "search" hierarchical level, than the record level. Users may also be assigned and enabled to apply attributes to the search (e.g. an attribute on the quality/relevance or other attribute of the overall search). A higher hierarchical level than a search may be a "matter" hierarchical level. For example, a matter may incorporate a plurality of searches. A lower hierarchical level than tecord may be a "document". For example, a single patent record may include a plurality of published documents (patent specifications for each country in a patent family, for example), In an embodiment, the attribute allocation means may require that at least one document be accessed by the user so as to ensure that each record has been properly considered. In an embodiment, the system further comprises an attribute definition means which allows a user to define attributes. For example, an administrator may define attribute types for a particular matter or search (where hierarchical levels are implemented). A user may be given permission to define attributes that that user could apply (and perhaps other users). In at least an. embodiment, the present invention has the advantage that it enables a collaborative approach to review of records. For example, where patent searches has been performed, a number of users (e.g. inventors, clients, patent attorneys), may collaborate in reviewing the patent searches and each apply attributes to records or other hierarchical levels which have been reviewed. Different users may be allowed access to different levels or different records for their input. Users may review (depending upon allowed access) attributes allocated by other users, to facilitate then- own review.

In an embodiment, the system further comprises a report generator for generating reports following review of the records. In an embodiment, the system further comprises an importation means enabling importation into the system of records from one or more sources. The importation means may enable importation into the system of records from a plurality of searches. Bi accordance with a second aspect, the present invention provides a method for facilitating review of a plurality of records comprising the steps of: allocating a plurality of records for review; assigning a user permission to access the records; and enabling the user to apply an attribute against one or more of the plurality o f allocated records.

In an embodiment, the step of assigning a user comprises the step of assigning a plurality of users, and the step of enabling the user includes the step of enabling a plurality of users, In an embodiment, the step of assigning users comprises the step of assigning the user's permission to access a user computing interface via which the plurality of records may be reviewed and also via which the attributes may be allocated.

In an embodiment, the method comprises the further step of applying a user identification associated with allocated attributes, whereby the user who has allocated the attribute can be identified.

In an embodiment, a plurality of records may be allocated from one or more searches. The searches may be documentary searches. The searches may be patent searches.

In accordance with a third aspect, the present invention provides a computer program comprising instructions for controlling a computing device to implement a method in accordance with the second aspect of the present invention.

Ih accordance with a fourth aspect, the present invention provides a computer readable medium providing a computer program in accordance with the third aspect of the present invention.

Detailed Description of the Preferred Embodiment

Figure 1 illustrates a computing system that may be used to implement a system in accordance with an embodiment of the present invention. Referring to Figure 1, a computing system 10 is shown, including a processor 2 and memory 4, linked by way of high speed bus 6. Input and output devices are shown in the form of monitor 8, keyboard 11, mouse 12 and keyboard 13. Computer system 10 in this example is connected via communications network 14, to a search system 16 comprising search engine 17 and electronic document database 18. The computing system 10 is loaded with software to enable implementation of a system for facilitating review of a plurality of records, in accordance with an embodiment of the present invention. Ih this embodiment the plurality of records are obtained irom the electronic document database 18, following a search. The records may be obtained from any other source, however.

Note that any computer hardware/software architecture may be utilised to implement an embodiment of the present invention, the iunctionality of which is described in the following pages. The invention is not limited to implementation by the type of computer architecture illustrated and described in relation to Figure I- For example, other arrangements such as central mainframe/terminal architecture, client/server architecture or any other type of arrangement may be utilised to implement the present invention. In one arrangement, a plurality of network computers may be utilised to enable, for example, a plurality of users to access the system from their own computer terminals. The network may be any network, the Internet for example- Figure 12 is a block diagram illustrating components of the system in accordance with this embodiment of the present invention. It will be appreciated that these components may be implemented by appropriate software running on a computer system such, as illustrated in Figure 1 (or other types of computer architecture).

In this embodiment, the system, generally designated by reference numeral 120 includes a user interface 121 via which one or more users may review a plurality of records 122 available for review via the u$er interface 121. In this example, the user interface 121 may include appropriate software accessible and controllable by way of monitor 8, screen 1, keyboard 11 and mouse 12. The user interface 121 may be accessible via a plurality of personal computers, for example, so the plurality of users can access the user interface 121. In one embodiment, the user interface 121 may be provided via Internet access to a server computer arranged to serve pages forming part of the user interface 121.

In thi$ embodiment, the system 120 includes an attribute allocation means arranged to enable any assigned user to apply an attribute against one or more of the plurality of records 122. In this embodiment, the attribute allocation means may include graphical user interface components provided by the user interface 121 , such as, for example, radio buttons.

In this embodiment, the system also includes an administrator interface 123, again accessible by appropriate computer hardware, for an administrator to provide input to the system. In this example, the administrator interface 123 enables the administrator to have access to a user assigning means 124 which enables the administrator to assign users permission to access the user interface 121. With this facility, the adrmmstrator can control user access to the system.

In addition, the administrator interface 123 allows the administrator access to an importation means 125 which enables the administrator to control import of records 122 into the system 120. In One example, the administrator may import search results from a number of different patent searches into the records 122 (e.g. from search results 126).

A further component of the system 120 is a report generator 127 which enables generation of reports based on a review undertaken by the administrator and/or users of the records 122.

In this embodiment, the user interface 121 includes a "workspace", including a number of computer screens, which enable a plurality of users to allocate attributes to records 122, as part of a collaborative review of the records. The system of this embodiment will hereinafter be described with the reference to a case study illustrating a review process for a plurality of patent records located by the search system 16. It will be appreciated, however, that the system 1 is not limited to review of patent records, but may be used for review of any other type of records, in particular, records obtained by a search (although not limited to records obtained by a search). Figures 2 to 5 illustrate computer screens which may be presented via administrator interface 123. Referring to Figure 2, firstly, an input screen 20 is shown which includes an importation means 125 for assigning patent records 122 to the workspace 1 of the user interface 121,

At this screen an administrator is presented with a list of patent records 22 that have been located by the search system 16. The search process will not be described in any detail, however for the purpose of this embodiment, it is realised that the records could be located from any number of patent databases using any number of different search queries. The searches do not even need to be obtained from patent databases, could merely be input to the system 120 manually (e.g. from a list of ϊirtematϊoaal search, results). An advantage of this arrangement is that searches from different databases can be input to a review system for a single collaborative review. The patent records are assigned to the workspace by clicking on the "select" icon 24 shown in the top right of screen. Also shown in Figure 2 is an identifier in the form of a matter code 26 to identify the particular review. Once the user has selected the patent records 22 to be assigned to the workspace they are directed to the selected records screen 30 shown in Figure 3. An indication of the number of records successfully assigned (imported) to the workspace is shown in the status box 32. In this instance, all 12 patent records were successfully assigned to the workspace.

Turning to Figure 4, there is shown an input screen 40 for allocating users access to the workspace. Ih the left hand portion of the input screen 40 there is displayed a list 42 of all users known to the system. In this embodiment the users are listed in alphabetical order, however it is envisaged that the users could be displayed according to their associated user type 44 which, according to this embodiment is indicative of the user's position. Any number of users can be allocated access to the workspace by selecting the corresponding check box 46.

Once the "save" button 48 has been selected, the list of allocated users is displayed on the allocated users screen 50 depicted in Figure 5. In this instance, three users 52 have been allocated access to the workspace. Allocated users 52 can be denied access to the workspace at any time by toggling the corresponding "status" icon 54, shown at the left of screen. Also provided is the "options" icon 56 for assigning further permissions and privileges to each of the allocated users. By clicking the "options" icon 56 a permissions screen can be accessed so as to select additional access options relating to viewing restrictions, attribute restrictions and the like.

A user "workspace" will now be described in accordance with an embodiment of the invention, with reference to Figures 6 through 9.

After logging on to the workspace, using conventional login techniques, each of the allocated users 52 is presented with a record review screen 60, an example of which is illustrated in figure 6. As shown, the record review screen 60 displays the list of patent records in a bibliographic form which comprising the following record descriptors: publication number 62, title 64, assignee name 66 and status 68. It is to be appreciated that any associated descriptors could be used to represent the patent records depending on the purpose of the review and so as to facilitate a more purposive display format. The allocated users 52 of the workspace can access a detailed summary of the individual patent records by clicking on an icon 69 associated with the descriptors.

Shown with reference to Figure 7 is a detailed summary screen 70 for one of the assigned records. In addition to displaying the detailed information, the summary screen 70 also provides a means to apply an attribute against the patent record- in. the form of radio buttons 72. In this embodiment the radio buttons 72 represent a measure of the record's relevance, whereby a rating of "3" corresponds to a highly relevant record and a rating of "0" denotes a non-relevant record, As illustrated here, the allocated user "George" considers that the patent record is highly relevant and has therefore selected a relevance rating of "3", The relevance rating, user name, user type and time of application axe stored against tfie record and displayed in the ratings box 74. Allocated users subsequently accessing the detailed summary screen 70 can view this information to aid in formulating their own opinion as to the record's relevance, In another form, this information may be suppressed to avoid biasing of subsequent users opinions.

Also provided at screen 70 is a ^<cRelated Publications" selection box 76. The selection box 76 provides links to full text specifications of the selected record. In this instance there are two full text specifications, namely AU 2001061704 and WO 2001/087290. The allocated user views the desired full text specification by clicking on the associated link,

Shown in Figure 8 is the full text specification screen 80 for the patent record AU2001061704. Each specification consists of six distinct sections which can be navigated to by selection of the corresponding tabs 82 found in the top right comer of the^' screen 80, under the heading "Document Type". Also provided in the full text specification screen 80 is a means to applying an additional attribute against the patent record in the form of a comments box 84. The comments box 84 records textual comments input by the allocated user against any one of the $ix sections. By clicking . on the "Save" button 86, the applied comment is saved and displayed in the aforementioned detailed summary screen of Figure 7 under the "Comments⁴* heading 78, In this instance George has applied the comment of "Claim 1 i$ particularly relevant" to the claims section. The full text specification screen 80 can be closed at any time by clicking the close button 88 found in the top right corner of the screen SO. Figure 9 shows a completed record review screen 90 where each of the allocated users has applied a rating and, where appropriate, comments to each of the assigned patent records 22. The star icons 92 depicted to the left of the publication number indicate that one or more relevance ratings have been applied to the patent record, while the comment icons 94 show that a comment has also been applied. By clicking on the desired icon 92, 94 the allocated user is directed to the corresponding ratings or comments box (see Figure 7) to readily inspect previously applied ratings and comments.

The administrator and/or users may view and manipulate the screen of Figure 9, depending upon access permission. Reports may be generated from the collaborative review process, the results of which are summarised on record review screen 90.

Turning to Figure 10, there is shown a report generation screen ΪOO for generating hard copy printouts for the list of patent records 22 and their applied ratings and comments. Using this screen an allocated user and/or administrator can convert the selected records, or parts thereof, into Postscript Document Format (hereinafter "PDF") suitable for print out by the printer 13 of Figure 1. As shown in Figure 10, an allocated user has filtered out records not having an applied rating of "relevant" for conversion to PDF. using the drop down box 104. To proceed to the next step, the allocated user selects the PDF icon 102 and is directed to the "Results Publication Typc(s)" screen 110 ofFigure 11. ^•

At the screen 110, the allocated user selects parts of the selected records that they wish to convert to PDF. In this example, the allocated user wishes to PDF the full text specifications associated with the selected record and ha$ therefore ticked the "Full Document" check box 112. The user also has the option of including information on all or selected parts of attributes and user details that have been applied to the records as part of the review process by ticking the appropriate box 113 in the coversheet section 114 of the screen layout 110. Once the desired check boxes have been ticked, the allocated user selects a continue button (not shown) and the selected parts are complied into a customised PDF report for the record review. This functionality also finds benefit where it is necessary to provide hard copies of relevant records for attachment to a search report that is to be provided to a client and the like. It is to be appreciated that this report functionality may be provided in formats other than PDF. For example, reports could be produced in HTML, XML and the like. The user interface 121 and associated methods of review provide for a more effective and considered review of records where multiple persons are employed in the review process. Records assigned to the workspace are less likely to be overlooked in the review process due to the visible association with attribute mdicators showing that the record has been previously considered by an allocated user. Furthermore, records can be organised and displayed according to their applied attributes. For example, where the applied attributes represent a measures of record relevance, subsequent users of the workspace can request that the selected records be displayed in order of relevance, allowing for a more considered review of only the relevant records.

In the case of a patent search, for example, the system of the present invention may allow a number of interested parties to collaborate to review one or more patent searches relating to a particular invention or technology. For example, inventors, researchers, patent attorneys, patent searchers could be allocated as users for input to the review process. Reports may then be generated providing results of the review process by the various collaborators.

Another aspect of the system of the above described embodiment is the provision for hierarchical levels of user access and attribute application. In the above embodiment, there are four "hierarchies^*'- From the top down, the hierarchies are: • matter;

• search;

• record; and

• document.

For patent searches, a matter may include a plurality of searches. The search will include a plurality of records, and a record may include a plurality of documents (for example, a patent record may include a patent family with a mrøber of patent specifications). Users can be allocated access to any level of the hierarchy. At low level, for example, a user may only be granted to access to provide attributes for document, or at a slightly higher level to a number of records. At higher level, however, an administrator may have control of an entire matter across a number of different searches. Attributes can be allocated depending on the level in the hierarchy. In the above embodiment, users are able to apply attributes to the records. In a further embodiment, means may also be provided to enable a user and/or administrator to define attributes to be applied. For example, where there is a search that relates to specific subject matter, attributes may be defined in relation to the type of subject matter e.g. where the subject matter is motor vehicles, a user may define attributes as being various brands or makes of motor vehicles. This feature is used to define attributes that can then be utilised by users to apply to the records. Where hierarchioal levels are implemented, the user may. define attributes for the hierarchical level e.g. attributes to b© applied to a particular matter or search.

In the above described embodiment, input of attributes, selection of users, importation of search results and generation of reports is generally controlled via a graphical user interface and various GUI components such as buttons, radio buttons, check boxes etc. The present invention is not limited to the use of a GUI or GUI components. Other methods of interfacing may be used, such as keyboard, touch screen or any other method of interfacing.

In the above embodiment, examples of attributes that may be allocated include written comments and radio buttons or check boxes indicating a "level" of relevance. Many other forms of attributes may be provided by the system, and the system is not limited to these attributes only. ϊa the above embodiment, an example is given of records being results of patent searches. The present invention is not limited to use with patent searches, but can be used for collaborative review of any records from any area or search.

It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.

Ia the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word "comprise" or variations such as "comprises" or "comprising" is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.
