- W2353772334 abstract "Currently,different provinces and distinct departments have their own different expert information systems with distributed and heterogeneous expert information,so expert information sharing is difficult and expert information retrieval based on keywords is inefficient in the practical applications.According to the above issues,this paper presents the implementation schema for the semantic-based expert information system.The concepts and relations in the expert domain are summarized by the 5W1H analysis method,and conceptual model of expert ontology based on 5W1H is created to model expert information based on semantic.Four-layered system structure for the system is built,and semantic reasoning rules are also defined.The algorithm of semantic rule reasoning and algorithm of semantic information retrieval by SPARQL are designed,to realize the function of reasoning and information retrieval based on semantic.The experimental results show that the expert information retrieval based on semantic has got improvement on information retrieval recall." @default.
