But in the bilingual English-Spanish word embedding space, the word embedding of "EEUU" sits close to the word embedding of "US" and the sum of word embeddings of "Estados Unidos" sit close to the sum of word embeddings of "United States".
a coreference model trained using English-Spanish bilingual word embeddings on English data has the potential to make the correct coreference decision between "EEUU" and "Estados Unidos" without ever encountering these mentions in training data.
