An architecture to support information sources discovery through semantic search

In most scenarios, different information sources coexist and their content overlap, thus requiring domain knowledge to discover, understand and integrate information. In general, information sources are not designed for integration and their descriptive metadata do not suffice to enable IIS to consistently and unambiguously discover which information sources contain the required data to be integrated. This paper proposes an architecture to discover information sources through the use of semantic search techniques on top of corporative metadata repositories. Our experiments using a prototype of the proposed architecture obtained positive results with regard to precision and recall.
