Multitask Pointer Network for multi-representational parsing

作者:

Highlights:

• Dependency and constituent trees are used by many artificial intelligence applications.

• These structures are separately produced by either dependency or constituent parsers.

• Our approach can parse any input sentence with both dependency and constituent trees.

• We just need to train a single model to efficiently produce any syntactic structure.

• It achieves state-of-the-art results on Penn treebanks and discontinuous German datasets.
