摘要： A knowledge-based system comprising a plurality of knowledge processors each of which includes a knowledge base and performs a reasoning process for replying to a request from a user, and a file server which is connected to the knowledge processors through a transmission line. When each knowledge processor cannot resolve the user's request with the knowledge base of its own, it sends a request message to the other processor or processors through the transmission line. Reply messages from the other knowledge processors complying with the request message are managed in correspondence with the requests by the file server which receives the reply messages, and when a predetermined condition has been established, a reply is given to the knowledge processor which is the source of the request. Thus, each knowledge processor replies to the user's requests while automatically switching the reasoning process in a local mode which utilizes only the knowledge base of the processor itself and the reasoning process in a multiple or global mode which is based on cooperation of the other knowledge processor or processors.

摘要： In an inference method using a rule, a rule condition part network and rule consequence part network are generated, an integral network of both the networks is used for inference. With this inference method, the inference is performed at high speed by setting a shortcut arc so as to process the inference along the pattern matchable network portion. Further, use of the integral network of the rule condition and consequence parts enables not only forward and backward inferences but also a bidirectional inference with intimate couple between forward and backward inferences.

摘要： PURPOSE:To increase the inferring speed by designating the deciding order of satisfaction of the conditions related to each frame, the storage of the interim results obtained in the decision processing for satisfaction of the conditions, and the range of the interim results to be stored, and deciding the satisfaction of the conditions on these designating operations. CONSTITUTION:A user himself/herself designates the designating order for satisfaction of the conditions, the storage of the interim results obtained in the decision processing for satisfaction of the conditions, and the range of the interim results to be stored respectively. In this case, the designation of a processing structure is described in a rule and this rule is decomposed into three parts, i.e., a condition part, a conclusion part, and a processing structure description part. Then the preceding three designating operations are prescribed at the processing structure designating part. Based on these designating operations, the satisfaction of the conditions are decided. Thus it is possible to decide the satisfaction of the conditions in accordance with the characteristic of each problem and also to increase the inferring speed.

摘要： PURPOSE:To enable a knowledge base of large scale to be divisionally processed and the processing of a computer to be performed by reducing required capacity and quantity of calculation of a main memory by performing inference by using the combination of data view in a designated inference unit with a rule when executing the inference. CONSTITUTION:The system comprises an inference mechanism 1, a stage controller 2, stage definition 3, stage definition 3, stage start-up definition 4, the rule 5, and a frame 6. And a function to define plural frame bases, and a function to define the inference unit by designating the pair of the frame base and the rule 5 are provided, and the inference is performed by using the combination of the data view in the designated inference unit with the rule 5 when the inference is executed. Thereby, it is possible to perform the processing by dividing the knowledge base of large scale and to reduce the required capacity of the memory and the quantity of calculation, which enables the processing with the computer to be performed.

摘要： PURPOSE:To constitute a knowledge data base system capable of flexibly coping with knowledge correction by independently providing a knowledge expression related to data access and writing conversion knowledge and inference knowledge independently of each other. CONSTITUTION:When an inference start signal is given through an interface 5, an inference mechanism 4 sends a conversion execution instruction 11 to a conversion mechanism 1. The conversion mechanism 1 takes out values from data base fields written in external data base entries in order from the top and stores them in frame slots. Inference is started after all of the input processing is terminated. After inference is ended, the conversion mechanism 1 takes out values written in frame slots in order and stores them in external data base fields. By this constitution, required data during inference is designated in a form of table.

摘要： PURPOSE:To attain processing using large quantity of knowledge by forming knowledge bases in plural processing means so that each processing means can request the resolution of a problem not resolved by information in its knowledge base to another processing means. CONSTITUTION:Plural knowledge processors 1A-1C are coupled by a loop-like transmission line 6, a file server 5 having a common memory 4 is connected to the transmission line 6 and each of the processors 1A-1C is constituted of an inference processor 10 and a communication processor 11. The processor 10 is provided with a knowledge base file 103, a request memory 105 for storing a request or the like from the server 5, etc., and the processor 11 is provided with a transmission buffer 113 for storing data to be sent to the transmission line 6, receiving buffer 114 for storing data received from the transmission line 6, and so on. When each processor 1A on the like can not process data by the information in the file 103, the processor 1A sends a request message to the transmission line 6 and receives a prescribed answer message from another processor 1B or the like.
