PROBLEM TO BE SOLVED: To provide a document sorting device which can supply information effective for analyzing a partial document set and also can extract many analysis information from a document set. SOLUTION: A document analysis part 102 extracts word information from a document that is inputted from a document input part 101 and a document sorting part 103 sorts the document into a partial document set on the basis of the word information. A keyword extraction part 104 extracts a keyword set from the partial document set and a relative word extraction part 105 extracts a relative word set of the partial document set by using a relative word dictionary. A partial document set information generation part 106 generates information on each partial document set and the relative information on these partial document sets on the basis of information on the relative word set, the keyword set and the document set of partial document set. Then a sorting result preservation part 107 preserves the sorting result of the part 103 and information generated at the part 106. |
