Abstract: A digital information analysis system includes a target selection unit that selects target digital information, a combination storage unit that stores each of a plurality of word combinations related to a predetermined specific item, a search unit that searches whether the plurality of word combinations stored in the combination storage unit are included in the target digital information selected by the target selection unit, a relation determination unit that determines the relation of the target digital information to the predetermined specific item on the basis of a morphological analysis result when the plurality of word combinations stored in the combination storage unit are included in the target digital information, and a determination result setting unit that associates the determination result of the relation determination unit with the target digital information.

Abstract: Disclosed is a forensic system capable of enhancing the accuracy and efficiency of classification work of whether to submit document information as evidence in a lawsuit by highlighting a portion including a specific keyword in a unit of a sentence. The forensic system includes: a database that registers a keyword for determining by a user whether a plurality of pieces of document information included in the digital information is related to a lawsuit; a retrieving unit that retrieves the keyword registered in the database from the document information; a sentence extracting unit that extracts a sentence including the retrieved keyword from the document information; a score calculating unit that calculates a score indicating a degree of relevance to the lawsuit using a feature value extracted from the sentence extracted by the sentence extracting unit; and a highlighting unit that changes a degree of highlighting of the sentence according to the score.

Abstract: It is possible to analyze digitized document information gathered to be provided as evidence in a legal action and to classify the document information to be easily accessible in the legal action.

Abstract: A forensic system includes a result information receiving unit that receives result information which is a determination result of connection between a lawsuit and a document group including a predetermined number of documents, which is extracted from document data included in digital information, by a user, an element selection unit that calculates evaluation values of elements which commonly appear in the document group in each result information item from the characteristics of the elements and selects the elements on the basis of the evaluation values, a score calculation unit that calculates a score of each document in the document data from the selected elements included in each document of the document data and the evaluation values of the selected elements, and a recall ratio calculation unit that calculates a recall ratio related to the determination of the connection to the lawsuit on the basis of the score.

Abstract: Embodiments of the inventive concept can extract digital document information related with a specific individual to achieve a work load reduction associated with evidentiary material preparation for litigation. Recorded digital information can be displayed and user-specifying information can be set for each of a plurality of document files. The user-specifying information shows which user contained in user information one or more document files is related with. A recording unit can record the set user-specifying information. At least one user is selected, and a document file where user-specifying information which corresponds to the selected user was set is searched. Additional information showing whether or not the searched document file is related with the litigation is set via a display unit. A document file which is related with litigation is outputted based on the additional information.

Abstract: Embodiments of the inventive concept can extract digital document information related with a specific individual to achieve a work load reduction associated with evidentiary material preparation for litigation. A specific individual is selected from at least one individual included in user information. Only digital document information which was accessed by the specific individual is extracted based on access history information regarding the selected specific individual. Additional information indicating whether or not document files in the extracted digital document information are each related with the litigation is set, and a document file related with the litigation is outputted based on the additional information.

Abstract: Embodiments of the inventive concept reduce the burden of creating litigant sources of evidence or other evidentiary materials in connection with litigation in a court of law. Designation of at least one document file included in digital document information is accepted and designation of a language into which the designated document file is translated is accepted. The document file, the designation of which is accepted, is translated into the language the designation of which is accepted. A common document file representing the same content as that of the designated document file is extracted from digital document information recorded in a recording unit. Translation-related information representing that the extracted common document file is translated by invoking a translated content of the translated document file is generated, and, based on the translation-related information, a litigant-related document file is output.
