DOCUMENT PREPARING DEVICE

PROBLEM TO BE SOLVED: To provide a document preparing device for supporting the preparation of a document to be transmitted through an information filter to plural users. SOLUTION: At the time of preparing a document stored in a document storing part 104, a document evaluating part 105 evaluates information to be provided based on significance corresponding to the level of interest of a user by using a profile stored in a profile storing part 101, and a display part 107 provides a key word whose significance is increased when added to the document to a document preparer. Therefore, a document to be transmitted through an information filter to plural users can be prepared.
