Key-Tree: An Approach for Enhancing Queriability of Form-Based Interface

Web users often post queries through form-based interfaces on the Web to retrieve data from the Web; however, answers to these queries are mostly computed according to keywords entered into different fields special in a query interface, and their precision and recall could be low. An enhancement in answering this type of queries can be achieved by considering closely related, previous queries submitted through the same interface, along with their answers. In this paper,we present an approach for enhancing the retrieval of other relevant answers to a form-based Web query using previous, relevant queries and their answers. Experimental results show that our query-rewriting approach achieves higher average for precision and recall.
