Gradient-Based Adversarial Factual Consistency Evaluation for Abstractive Summarization

no code implementations EMNLP 2021 Zhiyuan Zeng, Jiaze Chen, Weiran Xu, Lei LI

Based on the artificial dataset, we train an evaluation model that can not only make accurate and robust factual consistency discrimination but is also capable of making interpretable factual errors tracing by backpropagated gradient distribution on token embeddings.

Triangular Bidword Generation for Sponsored Search Auction

no code implementations27 Jan 2021 Zhenqiao Song, Jiaze Chen, Hao Zhou, Lei LI

Our proposed model is simple yet effective: by using bidword as the bridge between search query and advertisement, the generation of search query, advertisement and bidword can be jointly learned in the triangular training framework.

Taxonomy Completion via Triplet Matching Network

1 code implementation6 Jan 2021 Jieyu Zhang, Xiangchen Song, Ying Zeng, Jiaze Chen, Jiaming Shen, Yuning Mao, Lei LI

Previous approaches focus on the taxonomy expansion, i. e. finding an appropriate hypernym concept from the taxonomy for a new query concept.

Rethinking Text Attribute Transfer: A Lexical Analysis

1 code implementation WS 2019 Yao Fu, Hao Zhou, Jiaze Chen, Lei LI

We apply this framework to existing datasets and models and show that: (1) the pivot words are strong features for the classification of sentence attributes; (2) to change the attribute of a sentence, many datasets only requires to change certain pivot words; (3) consequently, many transfer models only perform the lexical-level modification, while leaving higher-level sentence structures unchanged.

On Tree-Based Neural Sentence Modeling

1 code implementation EMNLP 2018 Haoyue Shi, Hao Zhou, Jiaze Chen, Lei LI

To study the effectiveness of different tree structures, we replace the parsing trees with trivial trees (i. e., binary balanced tree, left-branching tree and right-branching tree) in the encoders.
