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.
