…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
