Abstract: It is possible to reduce a review load of a reviewer. A document management system acquires digital information recorded in a plurality of computers or a server and analyzes the acquired digital information for relevance to a lawsuit. The document management system includes a thread classification unit that verifies supplementary information of each piece of document data included in the digital information and classifies the document data into threads based on the supplementary information, a similarity analysis unit that extracts elements included in the supplementary information of the classified document data for each thread and analyzes similarity between the threads based on the extracted elements, and an integration unit that integrates the threads based on the similarity.

Abstract: In discovery, it is necessary to execute efficiently work and the like. A data analysis system (5) includes an identifying section (121) that, when a first word that indicates a predetermined action is included in data, identifies a second word that indicates an object of the predetermined action; and an association assigner (122) that associates attribute information that indicates an attribute of data including the first word and the second word with the first word and second word.

Abstract: Possible events in the future can be predicted by analyzing existing data. A document analysis system (1) includes: a score calculator (116) that calculates a score that represents a strength of connection of a document extracted from document information to a classification symbol representing a degree of relevancy between the document information and a litigation or fraud investigation; a phase identifying section (122) that identifies a phase by which a predetermined action to be a cause of the litigation or fraud investigation is classified along with development of the predetermined action, based on the calculated score; and a change estimation unit (120) that estimates change in the identified phase, based on temporal transition of the phase.
