Semantic Query Transformation for the Intelligent Integration of Information Sources over the Web

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