  6. …but not quite far enough Stronger: • Semantics is weak ) Some Collective Ontology Engineering Bigger: • There is no data like more data ) more data sources to create ) more data sources to include Faster: • Scaleability of querying ) a matter of science, not one of witchcraft! ) Impressive track record from tiny to medium size in 10 years

  7. Impacts • New ways of exploring data • Semaplorer (http://btc.isweb.uni-koblenz.de) • Parallax (http://mqlx.com/~david/parallax/) • New ways of mining data • New ways of relating data

  8. Conclusion New forms of collective intelligence generate semantic data ) Use them!
