  • (1) Big Q: Do you ever have a question about what you are watching? Would you like related information about something you have seen? Something someone mentioned? One option is to pause the TV, go find your smart phone or pad and start some google search. When you carry out the search, your device doesn't know what you were watching, nor what the specific scene was about. Wouldn't it be nice to have a system that knows what you are watching, knows what you like and that presents links to extra pieces of information to you? Technology only likely to be useful when audience , content and program genre match. (2) slide
  • (1) Currently developing tools using 2 program genres

ANCHORS Named Entities => e.g. Jan Sluyters, disambiguated wtih DBpedia link 4. TARGETS web content from WHITE LIST connected to the ANCHORS
