  • No. It isn’t dead. … We followed that with a couple of major upgrades - in particular the incorporation of a whole Linked Data ecosystem underneath OpenCalais for companies, geographies, products and a few other things. We were really excited about this new capability and we invested a lot of money in making it happen. We released it to moderate fanfare and were ready for a wealth of innovation and new OpenCalais-powered capabilities. It didn’t happen. We saw very little adoption and no fundamentally new capabilities being built. That caused up to step back and think about what we were doing. … Once you’ve evolved past the point your users care about, you have a moment of truth where you decide 1) our users are clueless, 2) maybe we’re doing something wrong. We chose option 2.

  • Calais is a Thomson Reuters initiative to encourage the wide deployment of semantic technologies in the information and content marketplaces. Originally launched in January 2008, the initiative has garnered wide attention due to its technical capabilities and "free to all" business model.

    The Calais Web Service ingests unstructured text and returns Resource Description Framework formatted results identifying entities, facts and events within the text. The service appears to be based on technology acquired when Reuters purchased ClearForest in 2007.

    Recent uses of the technology have included the automatic tagging of blog articles and the organization of museum collections.

    Calais uses natural language processing technologies delivered via a web service interface.
