"UK based Protégé Ltd has merged with San Mateo-based Voquette Inc in an all-stock deal, generating a new company called Semagix...Semagix applies patented semantic web technologies to aggregate, enhance,
integrate, analyse and manage all internal and external content. Its patented SCORE (Semantic Content Organization and Retrieval Engine) technology automates these processes and semantically meta-tags digital media of any type and format, so enabling organisations to make fast, intelligent associations between relevant content from multiple sources."
This is not the same as the Stanford Ontology tool Protégé.
They too have a paper on applying semantic technology to homeland security, with some rather spooky screen shots of detecting a terrorist (or anyone else you don't like).
