Schema Matching across Web Query Interfaces


Overview

This task matches query schemas across different Web query interfaces for sources in the same domain. Such schema matching is critical for integrating heterogeneous information sources, to enable query mediation. As searchable sources proliferate on the Web, there are often many sources that provide structured information in the same domains (e.g., books and automobiles). Integrating these sources is important because they often provide either alternative or complementary information of the same kind. The goal of this task is to, given many query interfaces from sources in the same domain, discover attribute matching across these sources.
