Word2vec math: king - man + woman = queen, mostly

In Which I Lose My Mind over Embeddings (HPLM Chapter 2)

Maayan Roth tests the famous word embedding equation king - man + woman = queen across three models: text8, enwik9, and GloVe 6B. All three return queen, but other equations fail, like paris - france + italy yielding venice, turin, or rome depending on model size. Roth also built an interactive app to explore word vector arithmetic.
