摘要： High-speed full document retrieval method and system capable of providing result of retrieval within practically acceptable short search time. Upon registration of documents in a document database, condensed texts are created by decomposing each of textual character strings of the documents to be registered into fragmental character strings in dependence on character species and by checking mutual inclusion relations existing among the fragmental character strings. A component character table is created in which characters occurring in each of the condensed texts are registered without duplication. The condensed texts and the component character table are registered in the data base together with the texts of the documents to be registered. Upon retrieval of a document containing a search term designated by a user, a component character table search is first executed to extract those documents which contain all species of characters constituting the search term by consulting the component character table, and subsequently a condensed text search is executed by consulting the condensed texts of the documents. Finally, a text body search is executed for extracting a document which satisfies query condition imposed on the search term by consulting the texts of the documents extracted through the component character table search and the condensed text search.

摘要： A neighboring plural-character occurrence bitmap of a practical capacity capable of eliminating noises by hashing is realized, and a high speed full text search is realized equivalently, by greatly reducing the number of documents to be searched even if a search term constituted by a combination of English characters and words is used. Text data is segmented into words, and n-character strings at every (m+l)-th character positions are extracted from each word. A neighboring plural-character occurrence bitmap is created which stores data representing a presence of each neighboring plural-character string at a certain entry thereof. N-character strings at every (m+l)-th character positions are extracted from a search term and the neighboring plural-character occurrence bitmap is searched by using a search control program. Since the neighboring plural-character occurrence bitmap is searched prior to searching condensed texts, documents not relevant to the search term can be discarded and a high speed full text search can be realized.

摘要： A parallel comparator for performing a parallel and high-speed processing for collation of partial character strings which are partially taken out of a plurality of character strings of interest to be searched out with a character string to be searched in which document data to be searched is arranged sequentially from a leading character, is provided in a front stage of an automaton executing device. Only when a part of the character string to be searched coincides with the partial character string set in the comparator, the collation of the remaining portion of the character string to be searched is performed by the automaton executing device. Also, it is possible to set "don't care" in which a character at any position in the partial character string is ignored at the time of comparison by the comparator and to set a negation condition in which the comparison by the comparator is made taking the negation of a character at any position in the partial character string.

摘要： A document retrieval method and system for retrieving, from a document database storing document data in the form of character codes, a document which contains given search terms and which meets a given search query condition. From documents loaded from the document database, a document containing terms which match the search terms is searched to generate document identification (ID) information including a document identifier of the searched document and containing match terms found to match with the search terms as well as term identifiers of the match terms and position information of the match terms in the searched document. A decision is then made as to whether or not the position information of the match terms satisfies a positional condition specified in the search query condition concerning a positional relation between the search terms, and match information is then generated indicating satisfaction of the search query condition when the positional condition is satisfied. Through a proximity condition decision, it is ascertained whether the match terms satisfy an inter-term distance condition specified in the search query condition. Through a contextual condition decision, it is determined whether the match terms satisfy a concurrence condition specifying concurrence of the search terms in a same sub-sentence, a same sentence or a same paragraph. Through a logical condition, it is decided whether the match terms satisfy a logical condition between the search terms specified in the search query condition.

摘要： A method and apparatus for performing a document information search to uncover specified text data containing a given search subject key word from a group of document text data stored in a memory. In the document information search method, two stages of presearch are carried out to perform the document search with respect to a desired subject key word. In a first stage of presearch, a character component table is generated in which the existence of character codes for every document is set forth with respect to all the character codes contained in the group of document text data of stored documents. The character component table is searched for all the character codes comprising a designated search subject key word to thereby extract all documents containing all the character codes comprising the search subject key word. Further, in the presearch step, all texts without the possibility of containing the search subject key word are eliminated. A comprehensive, narrowed text search is thereby performed in accordance with the search subject key word.

摘要： A method and apparatus for making document information search and a magnetic disk unit to be used for realizing the method and apparatus. In the document information search method, in performing document search with respect to a desired subject key word, two stages of presearch are carried out. In a first stage of presearch (step 402), a character component table (500) in which existence of character codes for every document is stated with respect to all the character codes contained in the group of document text data of stored documents is generated, and the character component table is searched for all the character codes constituting a desiredly designated search subject key word to thereby extract all the documents each containing all the character codes constituting the search subject key word. In a second stage of presearch step 403), contracted text data for every document in which adjuncts and duplication of repeatedly stated words contained in advance in the text data are eliminated is generated, and the documents each containing the search subject key words by word are extracted from the documents extracted by the first presearch. After the second stage of presearch, text search is performed in accordance with a neighbor condition, a contextual condition, or the like (step 404). Further, as a term comparator means, hardware (1106) for exclusive use for term comparison in accordance with a finite automation is employed. Further, as for different notation and synonym, inputted terms are once subject to different notation development in a different notation development processing portion (2601), each of the different-notation developed terms is subject to synonym development in a synonym development processing portion (2602) while referring to a synonym dictionary, and then the results of synonym development are further subject to different notation development in a different notation development processing portion (2603) in accordance with a conversion rule table (2603).
