by Jens Bowman, Sudhir Poole, Boris 9000

Main Research Hypothesis Main problems in SW:

Difficult to access knowledge sources unnatural query languages

Difficult to interpret results Who wants to read RDF fragments?

Existing user interfaces suck! We need a better one!

Our ideal:

Our 24 Hrs. (Research) Goals Provide a query-answering system

based on natural text Make Philipp jealous – we

Make Nenad jealous – we developed in 24 hrs. new query refinement techniques

Have fun!
