Multi-resolution model applied to knowledge base system for personalized service

This paper focuses on problem-solving expert system to generate the more personalized solutions. The multi-resolution model is combined into the knowledge base organization of expert system. Firstly, the combination possibility of multi-resolution model and knowledge expert system is discussed and the multi-resolution organization structure and representation of knowledge base is proposed. Secondly, the choice process of multi-resolution model based on user model is given. The new system based on it can automatically select appropriate model and carry out abstract reasoning and concrete reasoning to meet different requirements of users. Finally, the application example in the intelligent problem-solving expert system verifies the proposed model is feasible. © 2012 Springer-Verlag.
