Psychological Counseling Of Expert System Based On Weighted Fuzzy Reasoning

The research of this paper is supported by the key science program of Beijing Education Committee and by the key program of the natural science foundation of Beijing.(No.KZ200810028016)This paper used expert system technology in the college psychological consultation and researched the theory and technical problems of building university students psychological consultation expert system,which has important practical and theoretical significance for the actual needs of college psychological job.Because knowledge in the psychological field has the feature of accurate statements difficulty, this paper applied of fuzzy knowledge representation method and the weighted fuzzy reasoning method.In this paper,the main achievements are summarized as follows:(1)I designed the various components of the psychological consultation expert system,in accordance with the composition of the structure,combined with system analysis,including the knowledge design,the design of knowledge acquisition,the design of the reasoning module and the design of auxiliary module.(2)Researching and analyzing the fuzzy theory and the weighted fuzzy theory, for the uncertainty characteristics of knowledge,rules and re reasoning process in the psychological consultation expert system.(3)Researching on the fuzzy weighted rules,making use of the knowledge representation of the fuzzy production rule,designed weighted fuzzy reasoning algorithm and structure the weighted fuzzy reasoning machine,by supporting the aggregation operator of different the fuzzy logic relationship between sub-proposition. For the lack of interactive features in common weighted fuzzy reasoning algorithm, this paper improved it and applied it to the university students psychological consultation expert system,realizing the uncertainty reflect for the knowledge and reasoning through the interaction style.(4)Realizing the main functions of university students psychological consultation expert system,by object-oriented programming method.This system has been implemented using Microsoft.net Frameworks and the SQL Server 2000 DBMS.On the one hand,because the topic which involved in the field is still in development stage,on the other hand,because time and experimental conditions,the system has also some flaws,which will be improved and perfected in subsequent days.
