An artificial intelligence expert system based on a knowledge management system and a construction method thereof

Abstract

The invention discloses an artificial intelligence expert system based on a knowledge management system and a construction method thereof. The method comprises the following steps: obtaining teachingmaterial information, question and answer information and user behavior information through the knowledge management system; carrying out Data structuring processing on the teaching material information, and constructing a knowledge graph according to the obtained structured data; Obtaining first association information according to questions and matched answers in the question and answer information, and updating the first association information to the knowledge graph; According to the user behavior information and the structured data in the knowledge graph corresponding to the user behavior, performing mining to obtain second associated information, and updating the second associated information into the knowledge graph. Therefore, online education content is directly used as a knowledge input source, and the knowledge acquisition cost is reduced. And more implicit knowledge is further mined according to the knowledge class information and the behavior class information of online education, so that the information breadth and the information depth of the knowledge graph are improved.

Description

technical field [0001] The invention relates to the technical field of knowledge management, in particular to a construction method of an artificial intelligence expert system based on a knowledge management system and a system applying the method. Background technique [0002] Artificial Intelligence (Artificial Intelligence), the English abbreviation is AI. It is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. Artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a manner similar to human intelligence. Research in this field includes robotics, language recognition, image recognition, natural language processing and expert systems, etc. [0003] Artificial intelligence walks on two legs: data-driven and knowledge-driven, but the current devel...

[0006] 2. Data-driven is only doing a good job in the field of artificial intelligence perception, but because there is no accumulation of basic knowledge of world cognition, it is impossible to bring artificial intelligence into the field of cognition

[0009] 1. Due to excessive costs, inability to open source compatibility, and limited computer computing power, expert systems are mostly explicit system theoretical outlines, and cannot sort out tacit knowledge th
