Bilingual lexicons form a critical component of various natural language processing applications, including unsupervised and semisupervised machine translation and crosslingual information retrieval.We improve bilingual lexicon induction performance across 40 language pairs with a graph-matching method based on optimal transport.The method is especially strong with low amounts of supervision.
