摘要
现有的CSSCI信息服务系统只能提供单一、线性的检索功能,检索效果不佳,主要原因在于后台数据组织的不合理。为此,提出使用基于本体的知识服务平台代替现有CSSCI检索服务系统的解决方案,提供知识层次的服务,以改善用户的检索环境。在提出基于本体信息检索系统一般模式的基础上,设计一个实用的基于CSSCI_Onto的知识服务平台KRSP_CSSCI_Onto,对该平台的基本功能和系统框架进行探讨,并据此开发一个试验性的知识检索系统,详细阐述本体在知识检索服务中的具体应用,包括用户检索式的语义扩展,查询结果的关联知识推荐,基于学术资源网络模型的知识导航以及基于规则库的知识关系检索等。
The CSSCI information services system can only provide single and linear retrieval, and the retrieval effect is not very good. The main reason lies in the unreasonable data organization background. Therefore, the authors put forward the solution which uses knowledge services platform based on Ontology instead of the existing CSSCI information services system, and provide the services in the level of knowledge, so that to improve the retrieval environment. The paper proposes a general model of information retrieval system based on Ontology, designs a practical knowledge services platform named KRSP_CSSCI_Onto, and gives the basic functions and system framework of the platform. An experimental knowledge retrieval system is developed hereby, and the applications of Ontology in knowledge retrieval services is expounded in detail, including semantic extension of search expression, related knowledge recommendation of query results, knowledge navigation based academic resource networks model and knowledge relationships retrieval based rule library.
