Cross-lingual word embeddings can be applied to several natural language
processing applications across multiple languages. Unlike prior works that use
word embeddings based on the Euclidean space, this short paper presents a
simple and effective cross-lingual Word2Vec model that adapts to the Poincar\'e
ball model of hyperbolic space to learn unsupervised cross-lingual word
representations from a German-English parallel corpus. It has been shown that
hyperbolic embeddings can capture and preserve hierarchical relationships. We
evaluate the model on both hypernymy and …
