I'm impressed with Cortex - All industry leaders (Google, Siri, Alexa) answer "Who killed John Wilkes Booth" with "Abraham Lincoln," but this gives the correct answer. It shows that it has a deeper understanding of it's data sources.

It's definitely impressive. However it still fails at questions like "How old is the Earth".

  Pretty cool. It answered 'how old is the president' correctly, but got confused with 'how old is the vice president' and gave president Bush's age. Fun to play with!

  Thanks for checking it out! There are definitely question domains that need work and some overfitting problems but we wanted to get this out to HN community early and see what they thought.

Thanks for pointing this out - we didn't know about this case and it's cool to see Cortex can answer it correctly! For data sources right now, we use Wikipedia for Cortex but we're planning to add additional ones soon to handle more questions (e.g. questions around movies, restaurants, etc.). There are definitely some questions (e.g. earth age) that we aren't as good at right now, but we're improving those!

I asked "What is taller, a dog or a giraffe?" and it didn't know. Common sense is not yet in the knowledge graph. Maybe it can't perform comparisons Also: "What is the largest city in Europe?" -> "New York City". "What is the largest city in the world?" -> "Gotham City" So it seems to make KB lookup errors and probably can't do logic/set operations.

  Right now we think of Cortex as a competitor to Google KnowledgeGraph and WolframAlpha, rather than a common sense knowledge graph. But, we hope to answer questions like that one day :)

  Correct, we can't do logic/set operations yet, but we can handle some graph traversal questions where the answer is the property of a n-off related entity like: (1) "Who is Arya Stark's father's wife?" or (2) "Mark Zuckerberg's wife's birthday"

    I also tried things like: How old is the French Prime-Minister? How old is the Portuguese President? President always defaults to Trump and Prime-Minister to May (May also responds with two different results even though it show the same text(/source?). Also in Sapien "Prime-Minister" wasn't recognized. I'm very excited about technologies like this one.

      Yes, this is definitely a class of questions we don't do right now, but have updates coming for soon! Good catch on "Prime-Minister", we will patch that.
