Document extracting device, document extracting program, and document extracting method

A document extracting program allowing a computer to serve as:

• similarity computing device to acquire a plurality of documents to be candidates for extraction and computing all degrees of similarity between the documents;
• and
• document extracting device to extract a combination of documents whose sum of the degrees of similarity between the documents computed by the similarity computing device is the smallest when any number of documents are extracted from among a group of the documents.
