信息检索技术在网络数据库中的应用研究

Research on the Application of Information Retrieval Technology in Network Database

以信息检索技术为脉络,结合Ei Village2、ISI Web of Knowledge、CSAIDS、EBSCO Host、ProQuest Online等多个著名检索平台综合分析布尔逻辑、位置逻辑、模糊检索技术、网络叙词表构建技术在网络数据库的应用,研究表明信息检索技术已深深植入网络信息资源管理之中,深入剖析信息检索技术,可以清晰揭示提问表达式的构建机理,掌握网络数据库的原理及使用方法,为网络信息资源评价和建设提供依据。

According tn the development of the information retrieval technology, this paper analyzes comprehensively the application of Boolean logic, location logic, fuzzy logic, network thesaurus construction technologies in network databases. Through the study of retrieval platforms such as Ei Village 2, ISI Web of Knowledge, CSA IDS, EBSCO Host and ProQuest Online, the paper shows that the information retrieval technology has been taking a very important role in the network information resources management. It also clearly reveals that the result of this research could provide some bases for the acquirement of evaluation principles and the construction mechanism of network information resources.
