Semantic query transformation for the intelligent integration of information sources over the Web

Ismail Khalil IbrahimWerner WiniwarterStéphane Bressan

With the proliferation of data sources (databases, knowledge bases, and applications providing structured and semi-structured data) over the Internet, a critical problem is how to find,extract, and aggregate relevant information. In this paper, we present and discuss a variant of an existing algorithm for Answering Queries Using Views by extending it to make use of the semantics of the database in the form of integrity constraints to support the intelligent integration of information sources over the Web.
