[wiki-research] Inference over Ontology + Data

[GerardM]

Hoi,
For your information, at http://wiktionaryz.org we have the basic
functionality to import ontologies in a database that is represented from
within a wiki. We have succesfully experimented with some big ontologies. It
is on our wish list to do OWL. This is to import (and export) and integrate
even more ontologies

When you want to import an ontology into a standard MediaWiki, you will be
able to get data in there. You are likely to get it in there in a structured
way. However, keeping the data structured will be a struggle. When you
import into Semantic MediaWiki, you will be saved as in: the data DOES go
into specific files.

Honesty has me say that WiktioanryZ is still very much pre-alpha, it does
not have the inference possiblities that you need.. However, we need the
same inference logic that everyone else needs and we are Open Source .. Free
Software ..

(thinking of this Sesame Street scene where the BIG monsters and the little
monsters are talking about coopering ...)

Thanks,
     GerardM
