本文提出了学科知识门户的逻辑模型,指出本体的构建是学科知识门户构建的核心,在此基础上剖析了基于本体的资源组织机制,并根据高校图书馆服务教学、科研实例,设计了一个语义服务本体模型,最后研究了基于推理的语义服务实现路径。研究表明,将本体作为学科知识门户的知识组织体系,不仅能提供网状的语义网络,还能揭示、定义丰富的语义关系,非常有利于知识发现和语义推理,从而满足用户一体化、知识化和语义化的创新需求。这正是语义服务的要求和目的。
This paper puts forward the logical model of subject knowledge portal and points out that the construction of ontology is the core of discipline knowledge portal construction. Based on this, it analyzes the resource organization mechanism based on ontology. According to the service teaching and research examples of university library, we design a semantic Service ontology model, and finally the path of semantic service based on reasoning is studied. The research shows that using ontology as knowledge organization system of subject knowledge portal can not only provide reticular semantic network, but also reveal and define rich semantic relations, which is very conducive to knowledge discovery and semantic reasoning so as to meet user integration and knowledge-based And semantic innovation needs. This is the requirement and purpose of the semantic service.
