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.

Re: [Dbpedia-discussion] Advancing the DBpedia ontology
Thanks for the hint Hugh, Actually this was quite easy to implement, we just needed a new mapping http://mappings.dbpedia.org/index.php/Mapping_en:Distinguish sample extraction: http://mappings.dbpedia.org/server/mappings/en/extractionSamples/Mapping_en:Distinguish It would be great if someone could pick up the rest of the related templates found here http://en.wikipedia.org/wiki/Template:Distinguish Any other ideas for templates we do not currently extract is of course more than welcome These will be included in the next DBpedia release Cheers, Dimitris On Tue, Feb 3, 2015 at 12:18 AM, Hugh Glaser h...@glasers.org wrote: Hi. Not sure how to ask this: It would be great if you could include the tags such as {{distinguish|James McEvoy}} which appears on http://en.wikipedia.org/wiki/James_McAvoy (I don’t see anything like that in the current dbpedia endpoint.) Perhaps as owl:differentFrom, or a dbpprop equivalent. Then I could harvest that stuff and put it in http://differentfrom.org (or it could usefully be published in a dump file, if you wanted to make my life easier :-) ).
