Hi all, just seen this thread. In case it was not known or already considered here, please see [1] as an example of how to use DOLCE-Zero foundational patterns to revise and reorganise DBpedia ontology and data. Best Aldo Gangemi [1] http://www.heikopaulheim.com/docs/iswc2015.pdf > On 02

Hi, thanks Heiko for spotting this. BTW in the original mappings for version 3.9 those axioms were all subClassOf. Probably something has gone weird in the versioning. My proposal, which I made two years ago, is that, since DOLCE mappings have the main goal to help integrity checking or top-lev

Hi, I think that Peter has good reasons to complain on the current status of the DBpedia ontology :) But besides debatable choices on names, I’d concentrate on the main issue, which is the data-grounding of the ontology. The major example is that there is no systematic checking of the relation b

Hi, this is one example of the limits in producing an ontology without considering the full range of data that it has to provide a schema for. See e.g. [1] for an approach of deriving "ontology patterns" from data, in order to optimize the semantics of the ontology. In DBpedia, one may want to e
