Abstract: Inducing multilingual word embeddings by learning a linear map between embedding spaces of different languages achieves remarkable accuracy on related languages. However, accuracy drops substantially when translating between distant languages. Given that languages exhibit differences in vocabulary, grammar, written form, or syntax, one would expect that embedding spaces of different languages have different structures especially for distant languages. I will present our work on understanding the behavior of linear maps learned by word translation methods. Additionally, I will present some initial solutions to the shortcomings of such linear maps.
