To optimize semantic reasoning with ontology-based,a method of ontology similarity calculation based on weighted is proposed. By defining the factor of depth and density,the impact of similarity calculation is resolved. Using Jena API,Lucene and other open-source toolkit,a query expansion method is proposed. Query expansion module result shows that compared with traditional similarity model and Subjective judgments,the weighted semantic similarity model improve the precision and efficiency obviously.
