    • Ability to “slice and dice” data in several dimensions: thematic, spatial, temporal, sentiment, etc.
  • Streaming data + background knowledge
    • Enables automatic evolution and serendipity
  • Scalable real time delivery
    • Using sparqlPuSH(SFSW’10)
use cases ipad scenario
Use Cases (IPad Scenario)
  • Location
    • Retrieve stream of locations where my product is being mentioned right now.
  • Consumer sentiment
    • Retrieve all people that have said negative things about my product.
  • Content suggestion
    • Retrieve all URLs that people recommend with relation to my product.
  • Related entities
    • What competitors are being mentioned with my product?
use case 1 location query
Use Case 1: Location (query)
  • Retrieve a stream of locations where my product is being mentioned right now.

  • Highlights
    • When a new competitor “appears” in the KB, no change is needed in the query => Automatic Evolution
    • We found interesting products that we didn’t initially consider as competitors of IPad(e.g. IPhone)=> Serendipity
