Re: [Dbpedia-discussion] Advancing the DBpedia ontology

Hi all,

I am currently working with Aldo Gangemi on exploiting the mappings to 
DOLCE (and the high level disjointness axioms in DOLCE) for finding 
modeling issues both in the instances and the ontology.

I will not be able to travel to the meeting either, but of course we 
will share our findings once we're finished, and probably also ask for 
some input and feedback.
