In an inference machine having a knowledge set portion which stores therein a set of knowledge items such as rules, and an inference portion which interprets the rules for execution; priority level information items which set precedence degrees among the rules within the rule set are stored in a plurality of series with respect to standpoints of users, one series which meets the standpoint of a particular user is selected from among the plurality of stored series of priority level information items, and the rule of the highest precedence degree is selected on the basis of the selected series of priority level information items, with the result that the rule conforming to the standpoint of the particular user is selected and executed. On the other hand, a plurality of optimum solutions for the respective standpoints can also be found in such a way that the different series of priority level information items are successively selected, whereupon the inference portion finds the solutions for the respective selected series of priority level information items.

A programmable logic device with ferroelectric configuration memories storing multiple configuration data sets. The device has programmable logic blocks, interconnections, and I/O blocks to provide desired logic functions. Those building blocks can be dynamically reconfigured by changing the selection of configuration data stored in the device's integral configuration memories. The configuration memories are divided into groups, so that they can be loaded concurrently with multiple configuration data streams. To protect the content of configuration memories from unauthorized access, the device employs an authentication mechanism that uses security IDs stored in the configuration memories. The device has a memory controller to provide an appropriate power supply sequence for ferroelectric memory cells to ensure the reliable data retention when the device is powered up or shut down.

An office information system has a plurality of work stations connected via a network to mutually exchange electronic mail, each work station including a control information definition unit for defining control information representing what kind of processing can be performed on mails after reception, a processing log memory unit for storing log information of operations which have been performed on received mail, a control unit for guiding a receiver by referring to both the control information and log information, a task tracking instruction unit for inquiring into the processing status of mail, and a task tracking unit for reporting the status in response to such a tracking instruction. The system stores and interprets control information relating to the flow of an OA object on the network, which has been conventionally involved in the memory of an office worker, and guides the office worker to work to be done by the office worker. As a result, the chance that the OA object will stagnate at a certain location is reduced, and the circulation of OA objects on the network is improved.
摘要:
An inference method and an inference apparatus for use with a knowledge base system and knowledge base system supporting method and apparatus using the inference method and apparatus wherein there are employed rules each being comprised of a set of (1) a condition description part including a condition stipulating a plurality of states of a frame representing an object and constituting an object world of at least one pair of a slot and a value thereof and (2) an operation description part stipulating an operation to be executed when the condition is satisfied. For an inference processing, a rule for which a condition of its condition description part is satisfied is executed according to an operation described in the operation description part. A condition judging sequence is specified for satisfaction of a condition for each frame of the condition description part of the rule. It is also specified whether or not information related to a processing result obtained from a condition judge processing on each said frame is stored in a memory. Condition judgements are achieved for satisfaction of conditions respectively associated with the frames of the condition description part according to the specified sequence based on the processing results in the memory, thereby conducting a reasoning operation.

A planning support system and process in a workstation having an operator interface, planning process feature, a data file server, and memory feature therein, characterized in storing a planner model having data indicating a plurality of planning actions in the data file server and indicating flow among the planning actions and having process times of the planning actions, and in processes executed by the planning process feature including setting an operator model on the basis of a planning request input through the operator interface, and including determining action of a first planning action to be executed according to the planner model on the basis of the operator model and for determining a second planning action to be executed following the first planning action, and including storing data needed for process of the second planning action into the memory feature until the process of the second planning action is started after process of the first planning action ends on the basis of the planner model. Parts of a model of the planning work usually made by man can be carried out by computer, and necessary data can be predicted according to process of the planning work of the planner to prepare in advance. This makes it possible that data supply time for the planner is made at a pace of his or her working process.

A method and apparatus for processing a knowledge which divides a knowledge base into at least two knowledge portions, that is, rule groups so as to permit the rule groups to be processed independently of one another, and selects, as a portion to be processed, only a corresponding divided knowledge portion based on characteristics of knowledge required for a knowledge processing in a scheduling problem which includes a large number of planning data to be processed and a plurality of restricting conditions, thereby enabling a highly efficient and high speed scheduling.

A rectifier circuit converts an alternating current into a direct-current voltage and outputs it as a power supply voltage. A ferroelectric holding circuit has a volatile holding circuit and a plurality of ferroelectric capacitors. Data held in the ferroelectric holding circuit has a read margin greater than that of data held in ferroelectric memory cells in a memory array. The ferroelectric holding circuit thus operates with reliability even if power that the semiconductor integrated circuit receives is low. Consequently, since the ferroelectric holding circuit is formed on the semiconductor integrated circuit to be implemented on an RFID transponder or a non-contact IC card, the communication range between the RFID transponder or non-contact IC card and a reader/writer can be extended.

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 information 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.

A dynamic network reconstruction method in which the node processing information such as a node processing volume and a ratio at which a node is satisfied is collected for all nodes to maintain an efficient network even when the characteristic of an object described in a condition clause is changed in a Rete network of a production system using the knowledge technology and the network is changed based on the node processing information.

A programming equipment is used for automatically constructing programs by selecting and interconnecting a plurality of previously prepared unit programs in accordance with instructions by an operator. A screen of a display unit is divided into a plurality of partial display areas. A memory has a plurality of unit storage areas, one for each partial display area, for storing unit program names and data flow specifications. The information of the respective area is displayed in block form on the display unit so that the operator can readily construct a process data flow by operating the input device while watching the display unit. The programming equipment reads out the area information from the areas in a predetermined sequence, and selects and interconnects the unit programs to construct the program corresponding to the process data flow.
