Hi Kingsley! The problem is: 1. How to KNOW which categories represent types. There are 5-10 approaches for this, based on NLP and ML. E.g. Yago2 assumes that if the head-word of the cat name is a plural noun, that's a class. MENTA improves this by looking for a head-word that's a countable noun. A lot of them tie up into Wordnet, some into OpenCyc/UMBEL. It's a hard research problem. 2. How to KNOW which category-entity instance is an exception. E.g. a category "Books of Author Xyz" is typically applied to the page "Author Xyz" and a naïve interpretation will conclude that the author is a book. In wikipedia, Categories are a navigational aid, i.e. "mere" links. The trick is how to find those links that are type links. > >> >http://dbpedia.org/c/9CH4UXVL -- shortened version of the above > > Kingsley, how do you get this? My question was about the shortening. Hacking the URL I find that the dbpedia URL shortener is at http://dbpedia.org/c/ But is there a quick way to invoke it from SPARQL results? Should I make a browser bookmark? ------------------------------------------------------------------------------ Dive into the World of Parallel Programming!
