Attention Is Indeed All You Need: Semantically Attention-Guided Decoding for Data-to-Text NLG

1 code implementation INLG (ACL) 2021 Juraj Juraska, Marilyn Walker

Ever since neural models were adopted in data-to-text language generation, they have invariably been reliant on extrinsic components to improve their semantic accuracy, because the models normally do not exhibit the ability to generate text that reliably mentions all of the information provided in the input.

Can Neural Generators for Dialogue Learn Sentence Planning and Discourse Structuring?

no code implementations WS 2018 Lena Reed, Shereen Oraby, Marilyn Walker

While neural generation methods integrate sentence planning and surface realization in one end-to-end learning framework, previous work has not shown that neural generators can: (1) perform common sentence planning and discourse structuring operations; (2) make decisions as to whether to realize content in a single sentence or over multiple sentences; (3) generalize sentence planning and discourse relation operations beyond what was seen in training.
