一种基于相似度矩阵的本体检索匹配算法

摘要

针对用户查询与知识文档间检索失配问题，提出了一种基于相似度矩阵的本体检索匹配算法。该方法是对现有的检索匹配算法的一种改进。方法利用领域本体来快速确定候选匹配集；进而从三个层次来综合计算元素间的相似度；利用相似度矩阵得到两本体间的相似度。实验结果表明，在查全率、查准率和响应时间方面都有较好的表现。%The retrieval mismatch problem between the user queries with the knowledge of the document, put forward a body re-trieval based on the similarity matrix matching algorithm. The method is an improvement on the existing search matching algo-rithm. The use of domain ontology to quickly determine the set of candidate matches;consolidated from three levels of similari-ty between elements;similarity matrix is the similarity between the two ontology. Experimental results show that it has a better performance in the recall, precision and response time.
