Structure-aware Sentence Encoder in Bert-Based Siamese Network

no code implementations ACL (RepL4NLP) 2021 Qiwei Peng, David Weir, Julie Weeds

Recently, impressive performance on various natural language understanding tasks has been achieved by explicitly incorporating syntax and semantic information into pre-trained models, such as BERT and RoBERTa.

Towards Structure-aware Paraphrase Identification with Phrase Alignment Using Sentence Encoders

no code implementations COLING 2022 Qiwei Peng, David Weir, Julie Weeds

Therefore, we here propose to combine sentence encoders with an alignment component by representing each sentence as a list of predicate-argument spans (where their span representations are derived from sentence encoders), and decomposing the sentence-level meaning comparison into the alignment between their spans for paraphrase identification tasks.

Representing Syntax and Composition with Geometric Transformations

1 code implementation Findings (ACL) 2021 Lorenzo Bertolini, Julie Weeds, David Weir, Qiwei Peng

The exploitation of syntactic graphs (SyGs) as a word's context has been shown to be beneficial for distributional semantic models (DSMs), both at the level of individual word representations and in deriving phrasal representations via composition.
