Problems solved by technology

[0003] The current expert system knowledge acquisition is basically a mechanical learning method based on experience. It is difficult to update knowledge, and knowledge rules often have serious inconsistencies, redundancy, and even combination explosions.
At present, there have been many research works on knowledge acquisition of rough sets, neural networks, support vector machines, etc., but not linked to expert system knowledge base

Embodiment Construction

[0014] A kind of expert system knowledge acquisition method based on Weka software described in the present invention, combines figure 1 The shown structure exemplifies the present invention in detail, and verifies the practical effect of the method described in the present invention.

[0015] A kind of expert system knowledge acquisition method based on Weka software, comprises the steps:

[0016] Step A, create a knowledge base, establish a rule table and a failure mode table, and establish a case library composed of training samples; based on historical accumulated data, conduct in-depth research on various failures and unqualified cases, and use statistical analysis methods to determine The structure of the rule table and failure mode table in the knowledge base. The rule table is generally composed of the preconditions of the rules, and the conclusion of the rules. The failure mode set is composed of fault codes, fault descriptions, and fault suggestions. Finally, the cas...

Abstract

The invention provides an expert system knowledge acquisition method based on Weka software. The method comprises the followings steps of: creating a knowledge library; extracting rules from samples by using the Weka software, and verifying the rules; and storing the verified rules into the expert system knowledge library for diagnosis of an expert system. By the method, the knowledge rules of the expert system can be automatically acquired, so that the expert system knowledge library is updated in real time; and knowledge is acquired reliably, the method is high in practicality, and the rules can be extracted by selecting appropriate data mining methods for various data.

Description

technical field [0001] The invention belongs to the technical field of information processing, in particular to an expert system knowledge acquisition method based on Weka software. Background technique [0002] With the development of high technologies such as aviation, aerospace, nuclear power plants, and robots, and the expansion of people's exploration of natural fields, the automation level of the system is increasing day by day, the scale is expanding day by day, and the complexity is increasing rapidly. In the face of complex systems, reliability, maintainability and availability are becoming more and more important. Especially in aviation, aerospace, navigation, nuclear industry, etc., due to their specific working environment, in principle, only success is allowed, and failure is not allowed, which puts forward higher requirements for the safety, reliability and effectiveness of the system. Fault detection and diagnosis opens up ways to improve system reliability, ...
