Abstract

We describe a machine learning approach, a Random Forest (RF) classifier, that is used to automatically compile bilingual dictionaries of technical terms from comparable corpora. We evaluate the RF classifier against a popular term alignment method, namely context vectors, and we report an improvement of the translation accuracy. As an application, we use the automatically extracted dictionary in combination with a trained Statistical Machine Translation (SMT) system to more accurately translate unknown terms. The dictionary extraction method described in this paper is freely available.
