基于本体的数字图书馆知识组织研究

20世纪80年代末以来，在人工智能和知识工程等新兴领域里，本体逐渐被广泛应用，也引起了图书情报界的极大关注。数字图书馆知识组织构建模式研究在基于本体的前提下为知识组织在语义层面上拓展了一个崭新的领域，为实现信息服务的语义化和智能化奠定了基础。本文介绍并阐述了本体的形式化模型以及本体的具体功能、概念、特点，同时分析了本体作为一种能在知识层次和语义上描述概念体系的相关工具在进行数字图书馆知识组织中的不足，并提出了基于本体的知识组织模式及流程。

On the Digital Library Knowledge Organization Based on Ontology

Since the 1990s, ontology is widely used in artificial intelligence, knowledge engineering and other fields, and has aroused great concern in library and Information field.
