PROBLEM TO BE SOLVED: To provide a document retrieval device enabling a user to retrieve a desired document without performing a special setting operation even if the user's taste or the like is changed with the lapse of time. SOLUTION: Formers and browsers of various documents stored in a Web server 3 are compared with a retrieval user to determine weighting factors related to various documents. On the other hand, for each of the documents stored in the Web server 3, the number of words recognized for matching by a collation part 18 is multiplied by the weighting factor to calculate the evaluation point of each document, and the documents are presented in descending order of evaluation point.
