Recently dependency information has been used in different ways to improve neural machine translation. For example, add dependency labels to the hidden states of source words. Or the contiguous information of a source word would be found according to the dependency tree and then be learned independently and be added into Neural Machine Translation (NMT) model as a unit in various ways. However, these works are all limited to the use of dependency information to enrich the hidden states of source words. Since many works in Statistical Machine Translation (SMT) and NMT have proven the validity and potential of using dependency information. We believe that there are still many ways to apply dependency information in the NMT structure. In this paper, we explore a new way to use dependency information to improve NMT. Based on the theory of local attention mechanism, we present Dependency-based Local Attention Approach (DLAA), a new attention mechanism that allowed the NMT model to trace the dependency words related to the current translating words. Our work also indicates that dependency information could help to supervise attention mechanism. Experiment results on WMT 17 Chineseto- English translation task shared training datasets show that our model is effective and perform distinctively on long sentence translation
