Easy-First Dependency Parsing with Hierarchical Tree LSTMs
Eliyahu Kiperwasser, Yoav Goldberg · Transactions of the Association for Computational Linguistics · 2016
We suggest a compositional vector representation of parse trees that relies on a recursive combination of recurrent-neural network encoders. To demonstrate its effectiveness, we use the representation as the backbone of a greedy, bottom-up dependency parser, achieving very strong accuracies for English and Chinese, without relying on external word embeddings. The parser’s implementation is available for download at the first author’s webpage.
