Concept Extractor

Last year ClearForest was bought by Reuters and Tim O'Reilly has covered the story of how the CEO of Reuters sees a Semantic future. This is one of those companies that I'd hope would become semantically enabled way back when. It would be good for other text mining companies like Autonomy and Inxight to jump on board too. The free web service provided "categorizes and links your document with entities (people, places, organizations, etc.), facts (person ‘x’ works for company ‘y’), and events (person ‘z’ was appointed chairman of company ‘y’ on date ‘x’). The metadata results are stored centrally and returned to you as industry-standard RDF constructs accompanied by a Globally Unique Identifier (GUID). Using the Calais GUID, any downstream consumer is able to retrieve this metadata via a simple call to Calais".
