Abstract: A seed document typifying document information delivery of which a user desires from user terminals through a communication line is registered to an information delivering service system. The system extracts feature characters from the seed document and creates a user profile for each user. Acquiring document information from an information delivering party, the system extracts the feature characters from the document information and compares them with the feature characters of the user profile. The document information is transmitted to the user terminal to which the seed document having a relevance ratio exceeding a predetermined level is registered. Receiving the delivery of the document information, the user evaluates the document information as “relevant” or “irrelevant” and inputs the evaluation result to the system. The system decides a delivery service fee to each user terminal by taking the evaluation from the user into account.

Abstract: A computerized document management system that manages and allows efficient viewing of attachment documents in groups of electronic mail messages is disclosed. According to one aspect of the system, a first program determines whether an electronic mail message sent and/or received via an electronic mail server is a task message. If so, task history information, including the main text of the electronic mail message, attribute information, and information about relations with other messages, is registered in a memory storage region. A second program then extracts attachment documents from the electronic mail message. A third program stores the attachment documents in the memory storage region. Attachment document management information, including attachment document filename, attachment document file size, electronic mail transmission date, sender name, and a pointer to the storage region of the attachment document, is stored in the memory storage region.

Abstract: A document search method and apparatus and a portable medium used therefor are described, in which when registering a document in a data base, the logic structures of each document to be registered are superposed one on another to generate a structure index in which the structure elements having the same position of occurrence in the document are represented by a single meta-node. At the time of document search, a mass of the meta-nodes meeting a specified structural condition is determined with reference to the structure index. A string index is searched with the meta-node identifiers as a key thereby to determine a mass of documents meeting the specified condition. As a result, a highly accurate structure-specified search is made possible on a document data base including a mass of structured documents.

Abstract: In the information filtering for presenting document information through the filtering using profiles as the search condition data, it is requested to urge a user to take a proper measure to obtain the result of distribution without any noise and omission at the time of information filtering by detecting existence of a plurality of similar profiles and old profiles and then notifying this fact to a user.

Abstract: In a text mining technique, if the system only extracts characteristic words and phrases frequently cooccurring with the respective components of an analysis axis as an analysis condition, similar words and phrases are extracted for any component. To clearly indicate existence of characteristic words and phrases which do not appear as cooccurrence words and phrases for other components of the analysis axis, it is desired to appropriately present distinguishable features between the components to the user. For this purpose, the frequency of appearances of a plurality of characteristic words and phrases in a document satisfying each analysis condition is calculated. As a result, multiple cooccurrence words and phrases and component-cooccurrence words and phrases are discriminatively displayed. It is therefore possible for the user to appropriately analyze the contents of a plurality of documents.
