King – man + woman is queen; but why?
I've never found the "vector space" of word2vec remotely satisfying. In order to form a vector space, you need to also be able to make sense of scalar multiplication, and you need to be closed under arbitrary linear combinations. What is 2king? What is 3king - 2green + 0.5brutality? You can kind of make sense of this for adjectives, but it really breaks down with nouns.
