2004: A Semantic Web Odyssey
OWL-DL
by Jens Bowman, Sudhir Poole, Boris 9000
Motivation The PL oracles said they will be…
not always available unreliable non-deterministic imprecise (deliberately?!)
Therefore, as willing and eager PhD students we decided to build…
The Tool The Semantic (Web) Oracle!
Powered by
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
implemented the system in 24 hrs. without having a clue of what we’re doing
Make Nenad jealous – we developed in 24 hrs. new query refinement techniques
Have fun!
