Problems solved by technology

[0006] The above methods mainly improve the matching efficiency of the rule engine based on the Rete network from the aspects of Rete network construction, intermediate matching result caching and filtering, and Rete network screening. Let the constructed Rete network have a better degree of node sharing, the rule constraints must be arranged in a certain order, and the wrong arrangement order will cause the constructed Rete network to fail to share nodes, and redundant matching is performed in the rule matching process. The present invention aims at Insufficient of this rule engine, a rule engine self-optimization method based on constraint frequency is proposed

Abstract

The invention discloses a rule engine self-optimization method based on constraint frequency, which includes the following steps: S1: counting the frequency of rule constraints, performing statistics on the constraints in all rule patterns; S2: processing the statistical results of rule constraint frequencies, Merge the pattern constraint frequency results according to the constraint name; S3: Alpha network construction, obtain the rule constraint list through rule constraint reordering, and construct the Alpha network in the Rete network; S4: Beta network construction, generate Rete according to the generated Alpha network Beta nodes of the network. This method solves the problem that the rules written by users in practical applications do not target the sharing degree of the Rete network, resulting in insufficient sharing of the Rete network built by the rule engine, improves the sharing degree of the Rete network, and reduces the Rete network built by the rule engine. The complexity of the network can effectively improve the efficiency of rule matching.

Description

technical field [0001] The invention relates to a rule engine optimization method, in particular to a rule engine optimization method based on rule constraint frequency. Background technique [0002] The rule engine is a generative system. The generative system is a part of the artificial intelligence system. It is mainly composed of a rule base and a reasoning machine, which provides the necessary rule execution mechanism to achieve a certain goal. The rule base is a set of rules about behavior, also known as the production formula, which is used for the basic presentation of knowledge in the expert system. The production is of the form IF <conditions>THEN <actions>, specifies actions to be executed under certain conditions. When a production is triggered, it means that the precondition of a production is matched; when a production is triggered, it means that the action of a production is executed. The description of the real world is called a fact, usually ...
