Web (and associated computing) is evolving
Web of pages - text, manually created links - extensive navigation
2007
1997
Web of databases - dynamically generated pages - web query interfaces
Web of resources - data, service, data, mashups - 4 billion mobile computing
Web of people, Sensor Web - social networks, user-created casual content - 40 billion sensors
Web as an oracle / assistant / partner - “ask the Web”: using semantics to leverage text + data + services - Powerset, Siri, Watson
