计算机信息检索中的本体构建研究

Study on the construction of ontology in computer information retrieval

利用本体理论技术,以最终检索需求应用为导向,结合"技术的更新在科研文献上能得到很大程度的反映"这一假设对本体中的概念进行进化,结合分类主题词表及百科等通用的知识库中的概念,半自动构造了一个计算机技术领域的本体,消除了构建本体过程中细节的干扰从而实现机器智能,从而为Web信息检索提供建议.

Making use of the theory and technology of ontology, directed by final retrieved demand application, combined with the assumption that the technical update can get a large extent of reflection on the scientific literature, the concept of ontology was evolved. Combined with the concept of common knowledge data in the classification, thesaurus and encyclopedia, an ontology of semi - automatic computer technology area was constructed, which eliminated the interference in the building process in order to achieve machine intelligence, providing useful suggestion for Web information retrieval.
