Abstract
An input section inputs a document set. A normalization section calculates a similarity as a relative value between documents, with respect to combinations of a plurality of documents, in the document set. The normalization section employs the tf·idf method. In tf·idf method, a document vector and a significance of a word included in the document is used to perform normalization to convert each similarity to an absolute value.
