DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 illustrates a computer 100 configured in accordance with an embodiment of the invention. The computer 100 includes standard components, such as a central processing unit 110, which communicates with a set of input and output devices 112 via a bus 114. The input and output devices 112 may include a keyboard, mouse, touch pad, display, monitor, printer, and the like. A network interface circuit 116 is also attached to the bus 114 to facilitate interconnectivity with a network (not shown).
A memory 120 is also connected to the bus 114. The memory includes executable instructions to implement operations associated with the invention. A legal categorization pre-processor module 122 includes executable instructions to analyze a set of documents in accordance with specified legal criteria and thereby produce a set of documents with associated legal categorizations that are inserted into a document queue 124. A legal categorization approval module 126 includes executable instructions to accept the legal categorizations associated with a document and invoke a subsequent document for viewing with a single input action (e.g., a single click of a mouse, a single tap on a touch screen, etc.).
FIG. 2 illustrates processing operations associated with an embodiment of the invention. The legal categorization pre-processor module 122 may be used to implement the operations 200-208 of FIG. 2. Individual documents within a set of documents may be isolated through the selection of filters 200, defining rules 202 and/or providing example documents 204 consistent with the legal categorization. This information is processed to initially categorize documents 206. As each document is categorized, it is loaded into a queue 208. Commonly coded documents may be placed adjacent to one another in the queue to facilitate the review of common documents. Once the queue is loaded, the documents may be processed, for example, using the legal categorization approval module 126.
The legal categorization approval module 126 includes executable instructions to implement the operations 210 through 220 of FIG. 2. In each cycle the next document in the queue is selected 210. The document is then displayed 212. If the initial categorizations within the document (e.g., those provided by the legal categorization pre-processor module 122) are accurate (block 214—Correct—Yes), then single action approval 218 results in acceptance of the categorization and the invocation of the next document in the queue 210. Prior to selecting the next document, global categorizations may be revised 220. That is, the legal categorization approval module 126 may include executable instructions to refine the initial categorizations based upon ongoing input from the user. The initial categorization criteria and/or the ongoing input from the user may be used to supply a confidence level for any given legal categorization. If the initial categorizations within the document are not accurate (block 214—Correct—No), the user may revise the document categorizations 216. Thereafter, single action approval 218 results in the selection of the next document 210. Optionally, global categorizations may be revised 220 based upon user input.
FIG. 3 illustrates a graphical user interface (GUI) 300 that may be used to support operations associated with the invention. The GUI 300 includes a filter pane 302, which lists a number of filters that may be used to categorize documents. In this example, available filters include filters based upon such criteria as email addresses (e.g., “To: CC: BCC”, “From”) non-email authors, concept groups, responsiveness, issues, subject codes, priorities and privileges. The GUI 300 also includes selectable issues in pane 304, which may be assigned to documents. The pane 304 includes a box 306, which allows one to specify new issues for document categorization, Thus, the GUI 300 may be used to collect information that is utilized by the legal categorization pre-processor module 122.
FIG. 4 illustrates a GUI 400 that may be used to support single action approval in accordance with an embodiment of the invention. The GUI 400 includes a block 402 to display a list of queued documents. Pane 404 displays a document to be reviewed. Pane 406 (also referred to as coding panel 406) displays coding or legal categorizations associated with the document in pane 404 (also referred to as document 404). In this example, the legal categorizations include specified issues, subjects, priority, responsiveness, attorney-client privilege and attorney work product. In an embodiment of the invention, a confidence level 408 is associated with each legal categorization. The legal categorization pre-processor module 122 may be used to supply the legal categorizations while the legal categorization approval module 126 may be used to update codes and confidence levels based upon user input. In one embodiment of the invention, clicking on a confidence level 408 results in highlighting of relevant portions within the document 404, which are associated with the confidence level, thereby allowing the user to understand the bases for a categorization.
FIG. 4 also illustrates a single action approval button 410. This button allows a user to accept the presented legal categorizations and invoke a subsequent document. Thus, with a single computer input action, a user may endorse legal categorizations and invoke a subsequent document. This streamlined approach saves time and effort in the event that no changes are necessary. Even if changes are necessary, a user may modify the coding panel 406 and thereafter press the single action approval button 410. The pre-populated legal categorizations allow for accelerated processing even when coding information needs to be changed.
FIG. 5 illustrates a GUI 500 that displays the queued document following the document displayed in FIG. 4. The GUI 500 includes a panel 502 to display queued documents. Observe here that processed documents are marked by a check, including the email 503, which was processed in FIG. 4. Pane 504 illustrates the current document. Pane 506 includes different coding information associated with the document in pane 504. The displayed coding information has associated conl1dence values 508. A single action approval button 510 is also shown in FIG. 5.
FIG. 5 also illustrates template buttons 512 which may be assigned to a document. For example, each template button 512 may have a pre-populated coding schema that may be applied to a document by simply clicking on the template button 512. FIG. 5 also illustrates additional features associated with embodiments of the invention, such as an expressions block 514 for document annotation and a highlighting tool 516 to facilitate user highlighting of a document.
