二型模糊系统理论及其在知识个性化推荐中的应用

Type-2 fuzzy system and personalized recommendation systems are the newest theory and platform emerging at the beginning of this century for subjective uncertainty complex modeling and saling promotion E-business intelligence platform, respectively. Large data growth and network socialization arise the complexities of business models and user behavior, which bring both new opportunities and challenges for the theoretical study of the former and applied research of the latter. With the solid, deep research accumulations and extensive, in-depth basis of international cooperation, this project plans to study the information process and knowledge representation theory with type-2 fuzzy logic and corresponding personalized recommendation models, algorithms and applications. They include: the representation of type-2 fuzzy uncertainty metric system and the model expansion of collaborative filtering with type-2 fuzzy logic system; The design optimization and calculation simplification of type-2 fuzzy systems and its dynamic type-2 fuzzy recommendation algorithm; The semantics extraction and representation method and their applications in knowledge based type-2 fuzzy recommended models; Type-2 fuzzy information aggregation decision theory and the recommendation algorithms with behavioral preferences and social networks; type-2 fuzzy system computer simulation and its recommended decision support system. The project provides background for the relevant theoretical research and the support method for the applied research, respectively. The project were of great theoretical significance and application value. It improves and complements the weaknesses of the research and research gaps in some extent.
