A service retrieval apparatus stores service data items, each including two words as input and output items and expression as condition, receives request data item including word as input item and expression as condition, acquires first word set which is set of words having meanings identical/similar to meaning of word as input item in request data item, retrieves group of service data items in each of which one word of first word set is included as input item, calculates condition similarity between meaning of expression in each one of group and meaning of expression in request data item, calculates priority of each one of group based on similarity between word as input item in each one of group and word as input item in request data item and condition similarity, and transmits list including priority and address of appliance which correspond to each one of group to first appliance.

Service retrieval apparatus and service retrieval method

An apparatus collects information stored in a host computer through a network. A correspondence acquirement unit acquires a correspondence between an information identifier of requested information and host identifiers of a plurality of host computers each of which stores the requested information. A first decision unit decides at least one host computer to retrieve the requested information by referring to the correspondence. A second decision unit decides a retrieval method used for each host computer decided by the first decision unit from a plurality of retrieval methods. A retrieval unit indicates retrieval of the requested information based on the retrieval method decided by the second decision unit and each host computer decided by the first decision unit.

A mobile agent mediates cooperation among schedulers by executing a cooperation protocol. For heuristics such as strategies and the order in which variables are decided, which are used as criteria of selecting the value of a variable from candidates, when the heuristics are to be built into a solving method of a constraint satisfaction problem, processes with regard to these heuristics are so substantially localized as to be capable of parallel execution. These processes capable of parallel execution, as autonomous operations of different mobile agents, can be under modeling in natural form, resulting in easy installation. This facilitates software construction for reflecting the heuristics in a solving method of a constraint satisfaction problem, as well as improves the maintainability and extendibility of software.

Cooperate processing units using stored cooperation problem solving knowledge and receive information to perform problem solving

A system smoothly performing information processing is realized by dynamically making a decision, when it becomes necessary for an agent currently located at a platform to make use of another platform, with regard to whether to cause the agent to move to the other platform or cause the agent to cooperate with another agent that exists at the other platform. The dynamic decision is made in response to situations, resulting in enabling the unified utilization of mobile and stationary agents. The decision of using either movement or cooperation is typically made based on platform information and agent information. Even if planning changes the plan of an agent and regardless of what agent is using which platform's resources, it is possible to easily establish whether movement or cooperation is to be used, based on the platform profile and agent attributes. Such a system can perform information processing in response to changing situations.

A system and method for processing a large constraint satisfaction problem quickly, including a subset generating module ( ), which divides a set of alternatives provided for a plurality of parts of a given problem into a plurality of subsets, such that each subset has not more than two alternatives for each part. For each subset generated by the division, a solution calculation module ( ) finds a solution by calculating combinations of alternatives satisfying a constraint between alternatives selected for each two parts. The calculation of a solution for a subset, such that each subset has not more than two alternatives for each part, requires a very short period of processing time, even if the parts are many. Thus, the sum of the times required for finding a solution for all the subsets is much shorter than the time required for finding a solution for the original problem without such processing.

A system and method for executing a plurality of programs for control of objects, in which states of the objects are first transmitted to the programs. The programs to which the states of the objects are transmitted are then independently executed. The executed results are evaluated, modified and then transmitted to the objects. Thereby the structure of the programs can be simplified, sequential development of the programs can be realized, and program maintenance can be facilitated. Further, a fault tolerance to bugs on software can be enhanced and perfect operation of the software functions can be realized.

When inexecutable event occurs, an event format conversion rules table is referred to in order to convert the format of the event, then the communication message including the converted event is transmitted through a network. If the communication message is received through the network, the converted event is re-converted into an event that has an executable format by referring to the event format conversion rules table. An event filter refers to an event filter table that has processing necessity information for each event and sends only an event that needs to be processed to an event processing portion. Even if the local system cannot execute an event, the event is transmitted to another system through a communicating portion.

A high-reliability file system which surely keeps multiple file data on one drive even if some drives have failed. If renewal of a plurality of blocks of a disk by data in a buffer is necessary, a buffer manager renews the disk by all the data in the buffer which are to be renewed in the future. Flush management is carried out by the drive and the buffer manager. If another drive is 'examining' or 'renewing' when a flush (renewal) is to be executed, a sequencing means temporarily restrains the buffer manager from starting the flush.

Distributed file system for renewing data with high integrity

In a method of testing a color cathode ray tube, an electron gun assembly is energized to emit electron beams and only a horizontal deflection magnetic field is applied to the electron beams so that a line image is displayed on a screen. A degaussing coil is located in front of the panel and a degaussing magnetic field having a frequency the same as that of a commercial power source. Thereafter, the degaussing coil is moved in a direction away from the panel and is deenergized when the coil is removed from the panel at a predetermined distance. A vertical deflecting coil is energized to display an image and a picture quality of the tube is tested.
