Abstract

PURPOSE:To execute the cancel of competition by using the environment of a rule, to execute flexible control to the competition cancel and to improve the decoding ability of the rule by reproducing the environment at a time when rule is made successful in the case of canceling the competition to obtain an evaluated value. CONSTITUTION:A central processing means 2 is connected to a competition cancel system 1 and the evaluation function for the competition cancel to respective rule object is set to an evaluation function setting part A1 in an evaluation function operating means A of the cancel system 1. The evaluation function set by the setting part A1 is stored and the respective rule objects are generated to a system slot by a slot generating part A2. The evaluation function is stored to the generated slot by a slot storing part A3 and when the evaluation function set by the setting part A1 is made ineffective, the slot generated by the generating part A2 is deleted from the rule object by a slot deleting part A4. The evaluation function stored to the rule object, which is stored to the storing part A3, is referred by a slot referring A5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a conflict resolution method, and particularly to a conflict resolution method forming a part of an inference system.

[Conventional technology]

In conventional conflict resolution methods, the unique priority of each rule, the number of objects referenced by that rule, the generation time of the newest object referenced by that rule, etc. are used to resolve conflicts. is used as a guideline.

A document showing such a conventional conflict resolution method is Japanese Patent Application No. 181581/1983 titled ``Conflict Resolution Method with Specified Conflict Resolution Strategy''.

[Problem to be Solved by the Invention] The conventional conflict resolution method described above is based on the unique priority of each rule, the number of objects referenced by that rule, the generation time of the newest object referenced by that rule, etc. , but does not refer to the contents of the object, so it has the problem that it is difficult to perform detailed control to resolve conflicts.

In order to refer to the contents of an object in the conventional conflict resolution method, there is no success environment for a specific rule at the time of conflict resolution, so when checking whether a rule is successful or not, calculations are made within the rule at the same time. It is necessary to bind it to a variable and use it for conflict resolution.

When written in this way, the number of descriptions in the rule increases in addition to the original rule, making the rule difficult to read and the evaluation function itself difficult to read.

Therefore, in conventional conflict resolution methods, the contents of objects cannot be referenced when resolving conflicts, so it is difficult to perform detailed control over conflict resolution. Using a method in which values are calculated in advance has the disadvantage that the rules themselves become difficult to read.

An object of the present invention is to reproduce the environment at the time of a successful rule at the time of conflict resolution, execute an evaluation function therein to obtain an evaluation value, and perform conflict resolution using the successful environment of the rule. Detailed and flexible control over cancellation is possible, and the evaluation function is written into the system slot provided by the system, so there is no need to write extra rules in the rules themselves, the rules are highly readable, and the evaluation function itself is easy to read. The objective is to provide a conflict resolution method.
