    摘要: In a computer system having an interface with an I/O bus given disconnect/reconnect functions and a plurality of magnetic disk subsystems connected with the I/O bus, control divides a file at a disk access time with reference to disk management information, file management information and file descriptor translation information to read/write a plurality of such files asynchronously. Thus, high speed file access can be realized by only the plurality of magnetic disk subsystems without requiring any special control hardware. A corresponding relation between subfiles in a virtual directory and the application request file can be taken to construct the directory, thus making the divided storage transparent to the application.

    摘要: In associative memory device, a search key is stored in the first storage element and a storage key is stored in the second storage elements, respectively via a first data bus. The search key is supplied to the comparator via a second data bus, and the storage key stored in the second storage element is supplied to the comparator. The comparator compares the search key with the storage key. When the storage key is consistent with the search key, the comparator delivers as the associative operation results a comparison consistency output signal to a priority encoder circuit which outputs code information having a limited bit length. This code information is transferred to CPU via a selector circuit. If the comparator delivers a comparison inconsistency output signal, this signal is directly passed to CPU via the priority encoder circuit, so that the contents of the first storage element is rewritten. The first and second storage elements are designated by an address signal and data is read or written via the first data bus, so that they are used as a usual memory device.

    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 character string search arithmetic operation is performed at high speed with a small hardware scale processing module, such as a symbol string search module. The search module is connected to a CPU through address and data buses and includes a function definition section for defining a function of the apparatus in accordance with a command from the CPU, a data input/output section for receiving a symbol string to be searched through the data bus and for outputting the result of a search. A search processing section performs the search based on a function defined by the function definition section. A symbol string to be searched for, which is internally stored, is compared with the symbol string data input to the module's data input/output means. A condition holding section holds data indicative of an internal condition corresponding to the result of the search processing. Thereby, the CPU and the symbol string search module can perform the search at high speed.

    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.
