A document processing device includes: a document classification section configured to sequentially apply a plurality of classification processes in a prescribed sequence to a plurality of documents to classify the plurality of documents into a plurality of groups; and a classification determination section configured to every time one of the plurality of classification processes is applied, determine whether or not each group contains two or more documents. The document classification section, after applying a preceding one of the plurality of classification processes, applies a succeeding one of the plurality of classification processes to the two or more documents in each group determined as containing the two or more documents. The prescribed sequence is an ascending order of an amount of calculation involved in the plurality of classification processes.

[Problem to be Solved] Provided is a computer system that can accurately evaluate data to be analyzed without adding training data. [Solution] The computer system forms, from a matrix based on a co-occurrence frequency of first data elements forming at least one piece of data out of a plurality of data and second data elements appearing in vicinity of the first data elements, vectors for a plurality of data elements as the first data elements, calculates similarities for the first data elements on the basis of the vectors, and sets evaluation values for the first data elements on the basis of evaluation values corrected in accordance with the similarities.
