Encoder-Decoder Shift-Reduce Syntactic Parsing
This work addresses a gap in NLP for researchers by providing an incremental study on encoder-decoder models in transition-based parsing.
The paper tackled the lack of empirical study on encoder-decoder neural networks for transition-based syntactic parsing by applying a simple encoder-decoder model, achieving comparable results to Dyer et al. (2015) on dependency parsing and outperforming Vinyals et al. (2015) on constituent parsing.
Starting from NMT, encoder-decoder neu- ral networks have been used for many NLP problems. Graph-based models and transition-based models borrowing the en- coder components achieve state-of-the-art performance on dependency parsing and constituent parsing, respectively. How- ever, there has not been work empirically studying the encoder-decoder neural net- works for transition-based parsing. We apply a simple encoder-decoder to this end, achieving comparable results to the parser of Dyer et al. (2015) on standard de- pendency parsing, and outperforming the parser of Vinyals et al. (2015) on con- stituent parsing.
