Retrieving and semantically integrating heterogeneous data from the Web

Building Finder uses semantic Web technologies to integrate different data types from various online data sources. The application´s use of the RDF and RDF data query language makes it usable by computer agents as well as human users. An agent would send a query, expressed in terms of its preferred ontology (schema), to a system that would then find and integrate the relevant data from multiple sources and return it using the agent´s ontology. We discuss about retrieving and semantically integrating heterogeneous data from the Web.
