Query processing is a key problem in semantic caching.However,there are some deficiencies in the algorithms of the existent query processing,such as low efficiency of time and space as well as the complexity of the trimming result,which restricts the application of semantic caching.For overcoming the limitations,this paper developed a new method,which optimized the query trimming and invalid accessing to database,then gave the trimming algorithm of the probe query and the remainder query.Finally,the performance analysis of simulation experiment also indicates that the optimization technology is excellent more better than the non-optimization query trimming in improving the efficiency of time and space and reducing the complexity of trimming result.
