Query Result Aggregation on Multiple Search Engines

Abstract

As the rapid development of the network environment in recent years, we could get more and more Web resources, however some problems happened as followed, e.g., Lacking of the effective method of finding the Web resources. This problem is solved as the birth of the search engines, but there are some other problems and issues needed to be resolved. For some examples that will be mentioned in this paper: (1) for a short query, it is difficult for search engines to understand what users’ goal of the Web search. As a result, search engines are difficult to provide Web resources that are related to users’ search goal. (2) There is no effective method for helping the users to find their information need among search engines’ enormous indexes. Therefore, this paper will focus on continuing and improving the previous work about clustering on search engine returned results, and also try to study the suitability of pre-deciding that whether the query should be clustered or not, in order to avoid additional overheads both the search engines and users.
