An adaptive taxonomy-based query modification method for the web retrieval

摘要

We consider using the [f3]information provided by the existing taxonomy-based search engines for facilitating searches in other information resources in the web. For doing this, we send a user query to a taxonomy-based search engine, modify the query using a decision tree built from the retrieval results and send the modified query to other search interfaces available in the Web space. The query modification is adaptive in that it depends on the user query and a context selected from the taxonomy by the user. Furthermore, to give flexibility to users to control the retrieval performance and to deal with the variety of the search interface abilities, we propose a decision tree construction algorithm adapted for the web retrieval tasks. We conduct some experiments showing the usefulness and effectiveness of the proposed method and the algorithm.
