Keyword Aggregate Query Based on Query Template

摘要：

　　For keywords query,we propose a keyword aggregate query method based on query template.During the keywords processing,symbol table is used to locate the position of the keywords in the database to get a series of query items.In the query template generating stage,we design a heuristic query template generation algorithm.We use the improved scoring rules to rate the query templates,and select the optimal query template.The experimental results have shown that the aggregate query method is effective.
