Well done for the engineering feat here. Parsing Wikipedia at scale isn't easy.<p>Very surprised that they don't mention DBpedia though (<a href="http://wiki.dbpedia.org/" rel="nofollow">http://wiki.dbpedia.org/</a>) or discuss how they navigate through some big NLP challenges with Wikipedia, namely that many edits are made by bots.
Calculating context on mobile is a huge win for content providers, who can use the context to create deep links into other apps.<p>Example: I'm reading an article about James Bond, and ideally the phone can calculate that there's a new Bond movie, and I'm near a theater, and I'm free on Thursday night, and then create a link to buy tickets.
