A group of documents in a forum/message board are stored as a document group database in a predetermined server computer. A document group analysis device analyzes a group of documents contained in each set of documents corresponding to each message board in the document group database. A summation device generates a meta-index, a thread index, and an indexed file. A display device displays a group of documents in a display format of a keyword view, a thread view, or an author view using a meta-index and a thread index.

Statistical method for extracting, and displaying keywords in forum/message board documents

A compression unit compresses original data in block units and encodes compressed data, and it generates continuation flag information expressive of the block length of the compressed data at the top part of the compressed data stored in a storage unit. An expansion unit determines the block length of the remaining data of the compressed data on the basis of the continuation flag information, fetches the remaining data from the storage unit and restores the original data.

Apparatus and method for data compression/expansion using block-based

A pattern matching rule for recognizing a weakly linked idiom is previously held in a pattern matching section. If a weakly linked idiom which is registered in the pattern matching rule and has separately placed portions is present in an input sentence, the pattern matching section recognizes the idiom. If the weakly linked idiom is recognized by the pattern matching section, the idiom is replaced by a series of symbolized pattern expressions in a replacing section. A sentence subjected to the replacement process in the replacing section is given to an analyzing section. The analyzing section treats the series of symbolized pattern expressions as one idiom and analyzes the sentence. As a result, the result of analysis in which the weakly linked idiom is adequately processed is obtained as an output of the analyzing section.

This invention pertains to a dictionary-linked text base apparatus having a text searching function and text searching methods using this apparatus at various levels. This realizes a searched result with a higher degree of accuracy and, by linking a text base with an electronic dictionary, this invention enables searches at three levels: all texts containing the morpheme included in a searched object word at a morpheme level; all texts related to the grammatical attribute of the item in the electronic dictionary matching or including the morpheme at a syntactical level; and all texts related to no less than one concept of the item in the electronic dictionary at a semantic level. The invention includes an electronic dictionary for storing, in correspondence with an identifier for each item, no less than one morpheme identifier forming the item, an identifier of the grammatical attribute of the item, and a concept identifier. In addition, it includes a relative information part for showing an identifier for the related text in the electronic dictionary, in correspondence with each of the morpheme identifiers, the grammatical attribute identifier and the concept identifier in the electronic dictionary.
