I agree with Aaron and this the reason we started this effort. Even a small improvement in quality through the ontology could have a big impact. Improving the ontology should be an iterative process that will take into account both the data and the mappings. However, some decisions/actions can be m

The one thing I would say is that while I agree in general...the one thing that keeps eating away at me is that there is tremendous potential in dbpedia for bigger questions to be answered, but the more advanced analytics require that some level of sanity exists within the ontology...much more s

Hi John, My thoughts are for DBpedia to stay close to the mission of extracting quality data from Wikipedia, and no more. That quality extraction is an essential grease to the linked data ecosystem, and of much major benefit to anyone needful of broadly useful structured data. I think both Wik

John, You make a good point...but are we talking about a complete tear-down of the existing ontology? I'm not necessarily opposed to that notion, by want to make sure that we are all in agreement as to the scope of work, as it were. What would be the implications of a complete redo? Would the

Vladimir, I am more than happy to work the ML problem with you. For your example of the dichotomy with the domain and range of "mother" and queen Victoria being the "mother", this begs for contextual approach to that concept Aaron > On Feb 18, 2015, at 08:03, Vladimir Alexiev > wrote: >
