词汇本体知识及其在信息检索中的应用

Lexical Ontology and Its Application in Information Retrieval

本文介绍信息检索、语义搜索、本体知识、词汇本体知识等基本概念及其相互之间的关系,特别是Ontology这个概念的内涵从哲学本体论到信息技术的本体知识的演进、本体知识的构造与类别、跟汉语相关的词汇本体知识库的建设、本体知识特别是词汇本体知识对于信息检索和语义搜索的作用。希望向自然语言处理及其应用研究的学者展示词汇本体知识的特殊的资源价值;同时,也为语言学研究人员提供一些通向当代语言信息处理技术的路径,为汉语词汇学的研究注入面向工程应用的活力。

This paper introduces basic concepts including information retrieval, semantic search, ontology, lexical ontology, etc. Special emphasis is laid on ontology, which has evolved from a philosophical domain to the domain of information technology. The structures and types of ontology, the construction of lexical ontology in relation to the Chinese language, the roles that ontology(especially lexical ontology) play in information retrieval, and semantic search are adequately explained. We hope that such an endeavor will show the researchers on natural language process and its application that the lexical ontology has especial value as resource, and provide linguists with approaches to contemporary language information technology and will give impetus to Chinese lexicology in terms of project-oriented applications.
