Since the Internet found its way into daily life, placing product information at the user's disposal has become one of its most important tasks. As information sources are very heterogeneous concerning the provider as well as the structure, finding and consolidating the information for generating an allembracing view on a product has become an important challenge. An auspicious approach for resolving the emerged problems are federated search techniques enriched with Information Extraction and Semantic Web concepts. We investigate possibilities for federated product search combining heterogeneous source types, i.e., structured and semi-structured sources from vendors, producers and third-party information providers. The developed approach is evaluated with a Ruby on Rails implementation.
