Research On The Architecture Of Fuzzy Semantic Web And Reasoning On It

The concept of the Semantic Web was advanced by Berners-Lee in 2000.Computer in the former web showed information only, seldom involved in information processing.The former web ignored computer's use in information processing. The former web made the vast data cannot be effectively use and caused intelligent applications can not be used on the web. The target of the Semantic Web was that information on the web can be comprehended by computer. Accordingly, information on the web can be handled spontaneously to accommodate the quick growth of resources on the web and provided better service to human. At present, the theories of the Semantic Web put information and relations of resources as definitive. However, the semantic meaning of information is different among distinct domain, culture and social environment. Meanwhile, the semantic meaning also evolutes along with the change of the external world factor. So expanding the theory of the Semantic Web and pulling in ambiguity of resource description, relations among resources and changes of that are needed.Therefore, the thesis researched existing theory of the Semantic Web. On this basis, the thesis put forward the architecture of fuzzy Semantic Web and mainly studied on the concrete and abstract relationship description layers that are related to semantic and gave evolution machinery and methods to describe concrete and abstract relationship. At the same time, the thesis gave evolutionary algorithm of the Fuzzy Semantic Web and did analog experiment.The thesis researched the following research work specifically:1) Researched the mind and development status of the Semantic Web.2) Studied on layers RDF(S) and ontology in the architecture of fuzzy Semantic Web mainly and pulling in ambiguity of resource description. On this basis, the thesis put forward the architecture of fuzzy Semantic Web.3) Discussed the theory of the Fuzzy Cognitive Map.Applied the theory of the Fuzzy Cognitive Map to RDF(S). The thesis applied the theory of the Fuzzy Cognitive Map to RDF(S). The thesis added weight to property of the Resource Description Framework triples to express ambiguity and formed the Fuzzy Resource Description Framework. So as to enhance the ability to express and deal with complex knowledge and semantic.4) Studied ontology layer of semantic web, the thesis gave the defination of fuzzy ontology and its descripition, the thesis gave fuzzy OWL and use it to describe fuzzy ontology.5) Studied evolution of the Fuzzy Semantic Web. The thesis applied the theory of the Feedback Neural Network to evolution of the Fuzzy Semantic Web and proposed evolutionary algorithm of the Fuzzy Semantic Web.6) Constructed the analog system of the Fuzzy Semantic Web and evolution preliminarily on the basis of theoretical research. In order to test and verify application prospects of growing Fuzzy Semantic Web on enhancing intelligent of information search.
