摘要： PURPOSE: To disable even the third person, who knows the change method of the cipher system, from deciphering the communication contents on the way of communication. CONSTITUTION: This communication system consists of information processors 11 and 21 communicating with each other, a communication equipment 3 connecting them, and communication controllers 12 and 22 which control the communication at the time of communication passing them. Each of communication controllers 12 and 22 is provided with plural kinds of ciphering means 124 and deciphering means 123, a means 121 which obtains the frequency in appearance of communication data communicated between computers from the start of communication to the present, and a means 122 which generates and selects new ciphering rules.

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 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.

摘要： PROBLEM TO BE SOLVED: To use a computer with a user interface in a human-centered form and not in a computer-centered form by making the computer interactive in a multi-modal form such as voice, handwriting and gesture. SOLUTION: Paper 2 on a real disk 1, an environment viewer 3, a pen input computer 4, a keyboard 9, a pen with scanner 8, a microphone 6, a speaker 5 and a camera 7 are provided. The pen input computer 4 displays the file of a virtual desk top and executes application as the interface of real paper and virtual paper by using the pen with scanner 8, which incorporates a small CCD camera in the pen. The desk top is displayed in the environment viewer 3 and an intelligent agent 10 and the like are displayed on the monitor. The displayed agent 10 extracts a user intention from the multi-modal indication from an instruction (by pen, voice and gesture) for the system, solves a problem and outputs a result.

摘要： PURPOSE: To input information which are mutually related to at arbitrary timing through plural input means without considering an input procedure. CONSTITUTION: The respective input means 1-3 accept input at all times, add input time to the recognized result and output them. A recognition result selection part 4 merges or divides the recognized result, estimates the input time on the recognized result which is newly generated by division and collects the results whose input time is close as semantic analysis units. A semantic analysis part 5 refers to an instruction information table 10, and converts the notified semantic analysis unit into an operation instruction content. A command generation part 6 refers to a control information table 11, converts the operation instruction content into a command and issues it to a display part 7 or a DBMS part 8.

摘要： PURPOSE:To improve the throughput with good man-machine properties by performing inference only by known event data, and inquiring of a system operator and handling the known and unknown events so that maximum effect is obtained only when a sufficient likelihood ratio is not obtained. CONSTITUTION:An inference is performed by using events which are known to the system so as to improve the likelihood ratio of events that the operator of the system inputs up to a target value. Then it is decided whether or not the likelihood ratio of events to be decided about truth is sufficient. If the likelihood ratio is not sufficient, events which contribute to the truth decision making most among events whose likelihood ratios are not known are calculated and when there is an unknown even which contributes to the inference, the operator of the system is inquired about its likelihood ratio. The inference is carried on based on input values and the processing is repeated. Then, the inference result is outputted on a monitor and the processing is completed when there is no event which contributes to the inference or when the specified likelihood ratio is reached.

摘要： PURPOSE:To realize forward inference and backward inference with the aid of an identical network by allowing the forward inference to flow state quantity changed from a forward-root node being the summit node of the network of a condition part and allowing the backward inference to flow a goal from a backward-root node being the summit node of the network of a conclusion part. CONSTITUTION:When the network is made by positioning the network showing the rule condition part at an upper part and the network showing the conclusion part at a lower part, the node of a highest rank is made to be the forward-root node and the node of a lowest rank is made to be the backward-root and processing flowing to the backward-root node of the low rank from the forward- root node of the high rank is the forward inference and processing flowing to the forward-root node of the high rank from the backward-root node of the lower rank is the backward inference. Thus, not only the forward inference but also the backward inference and the bidirectional inference which the forward inference and the backward inference are closely combined.
