基于语义主题相似度的Web教育资源查询方法
A Novel Query Method on Web Educational Resources Based on Semantic Theme Similarity
摘要
Abstract
In order to make users acquire high availability of educational resources to solve the defects of the keyword search,a Web edu-cational resources query methods oriented semantic theme is proposed. This method builds the ontology concept semantic networks,on the basis of this,the concept retrieval method based on the semantic theme similarity matching is designed,that is the semantic theme was in-troduced into ontology concept semantic network,then a Web education resource vertical search engine was set up which blended with the semantic characteristic,and map the corresponding semantic distance into similarity by constructing a similarity function to meet the con-ditions,improving the query efficiency effectively. Experiment results show the method can improve information retrieval precision and recall.关键词
