Patent Document ID: 8452782
Application ID: 12919463

Base Claim:
1. A text mining device including a central processing unit (CPU) comprising: a first processor portion which includes an element extracting unit that extracts language elements from respective document data included in a pair of document data that comprises first document data and second document data related to the first document data, a plurality of the pair of document data being input to the element extracting unit; a second processor portion which includes a differential processing unit that extracts an element extracted from a description part of the first document data by the element extracting unit as a differential element, and outputs a set of the differential elements as a difference set, said description part of the first document data being related to a content that is not included in the second document data; and a third processor portion which includes a statistical processing unit that performs a text mining process including a process in which a degree of characteristic of the differential element against the respective differential elements included in the difference set is statistically calculated, a plurality of said difference being input to the statistical processing unit.

Claim 6:
6. The text mining device according to claim 1 , wherein the differential processing unit further comprises: an element associating unit that associates respective elements which are in identical, similar, synonymous, or analogous relation by comparing the elements of the document data between the first and second document data; a differential element extracting unit that extracts an element with no corresponding element of a pair in the association by the element association unit; and a differential block extracting unit that extracts a block of the element that does not include the corresponding element extracted by the corresponding element extracting unit from the document data as a differential block.
