Abstract

One interesting problem in data integration is, when users submit a query in one domain, he may also want to know more information in other domains which haven't come up to his or her mind yet. It's a great idea to recommend correlated domains to users so that they could get more information. However, the existing researches in solving this problem are quite rare and limited. In this paper, we propose a method of selecting query paths, and the query paths consist of correlated domains. We propose an entity class model which is based to construct a domain correlation graph, and query paths are picked based on the graph. At last we evaluate our method by experiments and demonstrate the effectiveness of our method.
