I'm not sure I get your point. The relationship between the categories “Chemistry” and “Acid-base chemistry” is present both in Wikipedia and in DBpedia. In Wikipedia, it can be seen as the first subcategory on the Category:Chemistry page. In DBpedia, it is expressed as a triple using the skos:broader predicate, which can be found in the “Categories (Skos)” dump: http://downloads.dbpedia.org/3.2/en/skoscategories_en.nt.bz2 > I know that wikipedia > categories are pretty messy, but I've found that graph traversals & > filtering can be applied to them to find members of classes that slip > through the cracks of more rigorous taxonomies -- I used methods like > that in the construction of > > http://carpictures.cc/ > > Are there any plans to improve category parsing in future dbpedia > versions?
