Hello, we are currently working on something to be able to model the ontology in Wikipedia directly. There was a discussion whether it would be better to have an own database with mappings, rules and classes, which would allow a consistent view on the engineering or if we would include it in Wikipedia. Both approaches have advantages and it was not a light decision. Wikipedia is, after all, a wiki so it might never be possible to get consistent information out of it. So, there is a strong incentive to allow ontology engineering at the place where the data comes from
We are still working on the live extraction and hopefully will face deployment soon, maybe within this week. Once this change arrives at the Wikipedia community, there will be many hands to clean up the extraction process and generate classes. By the way, did you offer some mails ago to set up a Portuguese DBpedia? Regards, Sebastian Hellmann, AKSW Nuno Cardoso schrieb: > Hello, > > I'm perfectly happy with this bottom-up ontology.
