Well, well, well. I know what I'll be playing with over the holidays. Some get Legos®, some get knowledge graphs. But seriously, I've been playing around with Wikidata's Query Service[0]. Here's an example...[1], the example asks, "What is `nature' a part of?" (Once you click through the URL shortener you can click execute to run the SPARQL[2] query. SPARQL's a W3C recommendation, sort of like SQL but for triplestores, but its details are not readily graspable I think.) It seems like Google's Knowledge Graph is based on Wikidata? I used to think the Semantic Web was always going to be a decade away but now I think that it is going to play a large part in the near future of the web though if you pushed me to explain my change in reasoning I don't think I'd be able. What we need are Semantic Web Browser, no idea what they'd look like though :( Here is Wikidata's table of properties from which it builds up its entire knowledge graph[3]. I think it's fascinating.

Wow, thanks! I didn't know there was a wikipedia knowledge graph. Looks like my holidays may be fun too :-)

  There are tons of RDF sources out there if you'd like: http://dbpedia.org/sparql http://dbpedia.org/sparql is generally accepted as a better curated resource (both in quality and quantity) http://data.linkedmdb.org/ http://data.linkedmdb.org/ http://www.rdfdata.org/ http://www.rdfdata.org/ I think the some subsets of the US federal government releases their data structured as such too

  Most of Google's data is scraped from Wikipedia, so either/or is probably pretty similar. I assume Google ranks the results of the data better, mind you.

Google's knowledge graph was in part based on Freebase, a large open knowledge base written by Metaweb. Google acquired Metaweb, continued to grow it's triple extractors [1] and eventually shut write access to the graph. Wikidata is slowly extracting information from the last public version of Freebase to grow out their own knowledge base.
