Abstract

This paper proposes a query routing infrastructure that aims at the Web text information retrieval. The routing information is distributed in each query routing node, and needs no central infrastructure, so it can be used in large distributed system to determine which node need to be queried to achieve the function of query routing in semantic network. At the same time, this paper proposes the concept of preference circle, which organizes Web text data sources efficiently , so querying the information for routing become simpler and easier for maintenance, which improves the efficiency of query routing. In addition, we demonstrate the advantages of our system in work load balancing and the completeness of result of query etc.
