从知识检索概念、知识检索基础、知识检索模型、知识检索呈现和知识检索系统几方面,对知识检索的有关理论与方法作了概要梳理和分析。认为知识本体作为领域知识的语义模型,其主要功能体现在知识组织和知识检索两方面;只有以领域知识本体的知识组织体系为基础,才能真正实现基于语义的知识检索。
With a brief discussion and analysis of the theory and method of knowledge retrieval, including concept, basis, model, presentation and system, this paper concludes that as the semantic model of domain knowledge, the main function of knowledge ontology is knowledge organization and knowledge retrieval.
