Re: [Dbpedia-discussion] Advancing the DBpedia ontology

Dear all,

     at OEG we are currently working on evaluating the DBpedia ontology 
from different perspectives: using OOPS! [1], inspecting manually the 
ontology for finding some modeling issues that could be improved 
(subclassOf issues, instanceOf issues, partOf issues, etc.), looking for 
modeling patterns in subdomains, and so on.
Of course, we will share our results when we finish the research in 
order to know your opinions and suggestions.

In addition, I read the googleDoc and included a pair of comments.
In this regard, one of the possible improvement of the DBpedia ontology 
could be to modularize the model in order to facilitate the search of 
concepts and properties (something similar to restructure the monolitic 
ontology into a kind of ontology network).

Unfortunately, I will not be able to attend the meeting, but at least 
two of my colleagues will be in Dublin.

Best Regards,

         Mari Carmen.
