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 existing CSSCI information service system can only provide a single, linear search function, search results are not good, mainly due to unreasonable background data organization. Therefore, a solution based on ontology-based knowledge service platform is proposed instead of the existing CSSCI search service system, and a knowledge-based service is proposed to improve the user’s search environment. Based on the general model of ontology information retrieval system, a practical knowledge service platform KRSP_CSSCI_Onto based on CSSCI_Onto is designed, and the basic functions and system framework of the platform are discussed. Based on this, an experimental knowledge retrieval system is developed. The detailed This paper elaborates on the application of ontology in knowledge retrieval service, including semantic extension of user search, recommendation of related knowledge of query results, knowledge navigation based on academic resource network model, and knowledge relation retrieval based on rule base.
