中文摘要：
为了解决利用主题词表构建的本体在描述上过于简单的问题,提出了一种优化主题词本体的框架。对主题词本体进行本体解析,在此基础上,对已有的相似度计算公式进行修改,给出了一种适合主题词本体的综合的相似度计算公式,并制订了优化主题词本体的规则,设计了相应的算法,将优化主题词本体功能发布成了语义Web服务。该方法弥补了主题词本体在描述上的不足,实验结果表明了该方法的可行性和有效性。
英文摘要：
In order to solve the problem that the description of ontology built by thesaurus is too sample, a framework of optimizing thesaurus ontology is given. At first, the thesaurus ontology is parsed, on the basis of this, after the existing similarity calculating formula is changed, an integrated similarity calculating formula which is suitable to thesaurus ontology is designed, and the rules of optimizing thesaurus ontology is made, and the corresponding algorithm is designed. At last, the thesaurus ontology optimization is released to a semantic web service. This method is very good to make up for the lack of the description of thesaurus ontology. The experimental result reveals that this framework is feasible and effective.
