Abstract

A forensic system including: a determination acquiring unit that acquires, as performance information, at least one of result information indicating a result of determination of relevance of plural pieces of document data included in digital information to a lawsuit performed by a user and progress information indicating information relating to a progress speed of the determination of relevance performed by the user; a recording unit that records the performance information acquired by the determination acquiring unit; a prediction information generating unit that generates prediction information relating to at least one of the result information and the progress information; an information comparing unit that compares the performance information with the prediction information; and an icon generating unit that generates an icon for presenting an evaluation of the determination of relevance performed by the user based on a comparison result by the information comparing unit.

Claims

1. A forensic system that acquires digital information recorded in a plurality of computers or a server and analyzes the digital information, comprising:

a determination acquiring unit that acquires, as performance information, at least one of result information indicating a result of a determination, performed by a user, of whether or not a plurality of pieces of document data included in the digital information is related to a lawsuit and progress information indicating information relating to a progress speed of the determination performed by the user;

a recording unit that records the performance information acquired by the determination acquiring unit;

a prediction information generating unit that generates prediction information relating to at least one of the result information and the progress information;

an information comparing unit that compares the performance information with the prediction information; and

an icon generating unit that generates an icon for presenting an evaluation of the determination, performed by the user, of whether or not the plurality of pieces of document data included in the digital information is related to the lawsuit based on a comparison result of the performance information with the prediction information by the information comparing unit.

2. The forensic system according to claim 1,

wherein the prediction information generating unit analyzes a feature of the determination performed by the user from the result information, and generates the prediction information relating to the result information based on a result of an analysis of the feature of the determination performed by the user from the result information.

3. The forensic system according to claim 1,

wherein the prediction information generating unit further analyzes a state of progress of a relevance determination of a different user, and generates second prediction information relating to a progress speed of the relevance determination of the different user based on a result of the analysis of the state of progress of the relevance determination of the different user.

4. The forensic system according to claim 1,

wherein the prediction information generating unit further analyzes a state of progress of a past relevance determination performed by the user, and generates prediction information relating to a progress speed of the past relevance determination based on a result of the analysis of the state of progress of the past relevance determination performed by the user.

5. The forensic system according to claim 1,

wherein the icon generating unit changes a display format of at least one of a motion, a serif and an expression of the icon based on the comparison result.

6. The forensic system according to claim 1, further comprising:

an extracting unit that extracts the plurality of pieces of document data from the digital information to generate extracted document data;

a display unit that displays the extracted document data on a screen;

a result receiving unit that receives the result information of the determination performed by the user with respect to the plurality of pieces of document data;

a selecting unit that classifies the extracted document data, for each determination result, based on the determination made by the user, and analyzes and selects a keyword that appears commonly in the extracted document data;

a keyword recording unit that records the keyword;

a searching unit that searches for the keyword recorded in the keyword recording unit from the extracted document data; and

a score calculating unit that calculates a score indicating a relevance between the determination result and the extracted document data using a search result of the searching unit and an analysis result of the selecting unit,

wherein the prediction information generating unit generates the prediction information relating to the result information using the score.

7. A forensic method for acquiring digital information recorded in a plurality of computers and a server and analyzing the digital information, comprising:

acquiring, by a computer, as performance information, at least one of result information indicating a result of a determination, performed by a user, of whether or not a plurality of pieces of document data included in the digital information is related to a lawsuit and progress information indicating information relating to a progress speed of the determination performed by the user;

recording, by the computer, the performance information which is acquired,

generating, by the computer, prediction information relating to at least one of the result information and the progress information;

comparing, by the computer, the performance information with the prediction information; and

generating, by the computer, an icon for presenting an evaluation of the determination, performed by the user, of whether or not the plurality of pieces of document data included in the digital information is related to the lawsuit based on a comparison result of the performance information with the prediction information.

8. A non-transitory computer readable medium comprising instructions executable by at least one processor and causing the at least one processor to perform a method of acquiring digital information recorded in a plurality of computers and a server and analyzing the digital information, the method comprising:

acquiring, as performance information, at least one of result information indicating a result of a determination, performed by a user, of whether or not a plurality of pieces of document data included in the digital information is related to a lawsuit and progress information indicating information relating to a progress speed of the determination performed by the user;

recording the performance information which is acquired;

generating prediction information relating to at least one of the result information and the progress information;

comparing the performance information with the prediction information; and

generating an icon for presenting an evaluation of the determination, performed by the user, of whether or not the plurality of pieces of document data included in the digital information is related to the lawsuit based on a comparison result of the performance information with the prediction information.
