    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 text search method for structured documents and apparatus wherein structured document database to be searched is created by adding logical structure length information to logical structure discriminating information on the basis of a structured document constituted by a plurality of logical structures and logical structure discriminator information, and in searching the structured document database in accordance with an entered search key constituted by a logical structure and a search character string, the search of a logical structure other than the entered logical structure is skipped based upon the data length information. In the method and apparatus, by using a structured document, structured document database to be searched is created which is constituted by a condensed text for each logical structure constituted by a list of words contained in the logical structure, a character occurrence bitmap for each logical structure constituted by a list of characters contained in the logical structure and an source structured document, and then the structured document database is searched in accordance with an entered search key constituted by a logical structure and a search character string. An source structured document is searched optionally depending upon the entered search key.

    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 document search method and system for searching and retrieving a document containing a specific character string in response to search requests issued by a plurality of search request sources. When a search request is received in the course of execution of a search processing for an earlier prior search request, the former is stored in a queue buffer. When a plurality of search requests have been stored in a queue buffer in this manner, a search processing is performed for the plurality of search requests simultaneously as stored. The results of search processing as performed are then distributively outputted to the relevant search request sources, respectively. Output buffers for storing a set of search results of the search processings performed in the past may be provided in correspondence to the search request sources, respectively, for screening the documents for which the character string search is to be performed.

    摘要: A character stream search system using an FSA for determining at a time whether or not a plurality of character streams as search objects exist in a search character stream which undergoes a search operation and which comprises a plurality of characters expressed with codes. In the system, a collation is conducted between the search character stream and a search object character. In a case where there exists a matched search object character as a result of the collation, a state transition is carried out of a predetermined state indicated by the FSA. In a case where there does not exist a matched search object character, a failure processing to effect a state transition to a transistion destination which is determined in association with the configuration of the FSA. The following processing is completed at a count which is a predetermined upper-limit value for each character undergone the search operation.

    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.
