We show that semantic relationships can be used to improve word alignment, in ad- dition to the lexical and syntactic features that are typically used. In this paper, we present a method based on a neural net- work to automatically derive word simi- larity from monolingual data. We present an extension to word alignment models that exploits word similarity. Our exper- iments, in both large-scale and resource- limited settings, show improvements in word alignment tasks as well as translation tasks.
