Abstract:
PROBLEM TO BE SOLVED: To compare a cluster with the other one and to extract a pattern peculiar to the cluster.
SOLUTION: In a document information analysis method, a multi-supporting pattern set generation part 4 calculates a supporting rate being the ratio of the number of document information in whose cluster the pattern appears to the number of all document information belonging to the cluster on the respective patterns corresponding to the cluster designated by a control part 3, selects the pattern whose supporting rate is more than the prescribed minimum supporting rate and outputs it to a high certainly pattern output part 5. The high certainty pattern output part 5 calculates certainty being the ratio of the number of document information in whose cluster the pattern appears to the number of all document information in whose cluster the pattern appears and selects the pattern whose certainty is more than prescribed minimum certainty.
