Abstract

The goal of translation is to preserve the original text meaning. However, lexical-based machine translation (MT) evaluation metrics count the similar terms in MT output with the human translated reference rather than measuring the similarity in meaning. In this paper, we developed an MT evaluation metric to assess the output of MT systems, semantically. Inspiring by the dependency grammar, we consider to what extent the headword and its dependents contribute in preserving the meaning of the original input text. Our experimental results show that this metric is significantly better correlated with human judgment.
