Abstract

String-to-tree MT systems translate verbs without lexical or syntactic context on the source side and with limited targetside context. The lack of context is one reason why verb translation recall is as low as 45.5%.
We propose a verb lexicon model trained with a feedforward neural network that predicts the target verb conditioned on a wide source-side context. We show that a syntactic context extracted from the dependency parse of the source sentence improves the model’s accuracy by 1.5% over a baseline trained on a window context.
When used as an extra feature for re-ranking the n-best list produced by the string-to-tree MT system, the verb lexicon model improves verb translation recall by more than 7%.
