Abstract


In this thesis research was supported by the science and technology project of the Beijing Municipal Education Commission of Beijing Natural Science Foundation of China project the ( ID : KZ200810028016 ) \This thesis focuses on the actual needs of today 's college students psychological counseling expert system technology is applied in Psychological Consultation and research to build the theoretical and technical problems of college students psychological counseling expert system has important theoretical and practical significance . The system according to the characteristics of the field of psychological counseling knowledge is difficult to accurately expressed the fuzzy knowledge representation methods and weighted fuzzy reasoning method . The main research work and achievements are as follows: (1 ) in accordance with the composition of the expert system structure , combined with the system requirements analysis, detailed design of the various components of the college students psychological counseling expert system , including the design of the design of the knowledge base , knowledge acquisition , inference engine design and the design of the auxiliary module . ( 2) the characteristics of psychological counseling expert system knowledge , rules and reasoning process uncertainty , fuzzy theory and fuzzy weighted theory research and analysis. (3) The weighted fuzzy rules , fuzzy production rules knowledge representation , by supporting sub Proposition fuzzy logic fuzzy aggregate operator is designed based on weighted fuzzy reasoning algorithm is constructed weighted fuzzy inference engine for weighted fuzzy reasoning algorithm lack of interactive features , improvements have been made on the average weighted fuzzy reasoning , and applied to college students psychological counseling expert system , achieved through the interaction reflects the uncertainty of knowledge and reasoning . (4 ) the use of object-oriented programming method , coding in Psychological Consultation main function of the expert system . The system uses Microsoft NET framework integrated development tools and Microsoft SQL Server 2000 database . The one hand because of the subject areas covered are still in the development stage , on the other hand , due to the restrictions of time and experimental conditions , and many other aspects of the system there are still deficiencies and weaknesses , to be further improved and perfected .
