基于本体的主题相关度算法研究

互联网上信息是海量的,并且还在快速的发展.面向主题的Web信息检索已成为当前研究的热点之一.将语义网技术同传统的信息检索技术相结合,给出一个利用本体判断主题相关度的判断算法,通过实验验证了算法的有效性.

Research in topic-specific algorithm based on ontology

There are huge amount of Web pages in Internet,and they are still increasing rapidly.The topic-specific Web information retrieval has been one of the hotspot being studied at present.Combining the semantic Web technology with the traditional information retrieval technology,an algorithm is given to calculate the relevance between the Web pages and the predefined topic utilizing ontology.The experimental system shows the effectiveness of the algorithm.
