Abstract:

Existing methods resolve the problem, which can not return retrieval results since the result set is respond to the univeral set of the keyword retrieval result. However, a non-null subset has more redunndancy as the result set. This paper proposed a keyword retrieval method based on perfect semantics, it made the semantics standradiztion for retrieval keywords. The way employeed different retrieval scorers to score keywords after distinguished keywords. Proposed the different type of retrieval algorithms based on the retrieval focus to generate linked tuple sets, which was transformed to a SQL retrieval sentence to return all query results for users. The experiments show that the method with retrieval focus avoids data redunndancy well.
