Abstract:
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.
