Syntactic Similarity for Ranking Database Answers Obtained by Anti-Instantiation
Flexible query answering can be implemented in an intelligent database system by query generalization to obtain answers close to a user’s intention although not answering his query exactly. In this paper, we focus on the generalization operator “Anti-Instantiation” and investigate how syntactic similarity measures can be used to rank generalized queries with regard to their closeness to the original query.
