Problems solved by technology

In existing expert systems, knowledge is usually expressed in the form of statement statements one by one, or realized through programming, but the above two methods have disadvantages
In the form of declarative sentences, the language expression ability is weak, the expression lacks flexibility and scalability, and input errors are difficult to track and prompt; the way of programming implementation requires domain experts to learn additional computer language and other knowledge, resulting in increased workload

Embodiment Construction

[0029] The present invention will be further elaborated below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0030] see figure 1 , shows a domain-oriented extensible expert system knowledge expression language system, which includes:

[0031] The language system has an ontology language library, which can satisfy the expression and description of ontology objects in different fields, and realize dynamic expansion in different fields;

[0032] In the field, the user domain language is used for knowledge expression, and the language includes two parts: grammar and vocabulary;

[0033] Based on the ontology language library, the vocabulary package of the corresponding field is generated, and the vocabulary can be dynamically and flexibly expanded without the need to recompile and release the so...

Abstract

A domain-oriented extensible expert system knowledge representation language system comprises an ontology language library, a user domain language, a rule editor and a language compiler, wherein the ontology language library can satisfy the expression and description of ontology objects in different domains, and realize the dynamic expansion of different domains, the user Domain Language (UDL) isused to express knowledge in all domains, which consists of grammar and vocabulary, domain experts can express knowledge flexibly by using familiar vocabulary on the premise of following the requirements of system grammar, avoiding the unnecessary process of learning computer code writing; vocabulary packs are generated based on ontology language library, vocabulary can be expanded dynamically andflexibly without recompiling and distributing software; the rule editor can help domain experts to express knowledge easily; the language compiler can convert the expert domain language into machine-recognizable computer language and start the reasoning engine to execute diagnostic reasoning. The system is flexible, efficient, friendly and scalable.

Description

technical field [0001] The invention belongs to the field of computer technology, and in particular relates to a field-oriented and extensible expert system knowledge expression language system. Background technique [0002] With the continuous improvement of safety awareness of manufacturing personnel, the transformation of production concepts, and the rapid development of computer technology and sensor technology, equipment condition monitoring and fault diagnosis industries have begun to flourish in our country. At present, domestic fault diagnosis is mainly carried out in a manual mode, which has disadvantages such as shortage of personnel, heavy workload, low efficiency, and low reliability. In order to solve the above problems and assist on-site personnel who lack professional knowledge to manage equipment effectively, expert systems came into being. Among them, the knowledge base is a very important part of the expert system. How to express the professional knowledge...
