We're holding an interactive session - Emerging Semantic Ad Platforms - on the Calais Web Service at the SDForum Semantic Web SIG. Calais Evangelist Tom Tague will discuss how Calais can be used to produce computable semantics from any text and feed them into any new search service, Semantic Web application or semantic ad platform. All are welcome. There is no charge for SD Forum members; non-members pay $15 at the door. No pre-registration is required.
