Length Control in Abstractive Summarization by Pretraining Information Selection

1 code implementation ACL 2022 Yizhu Liu, Qi Jia, Kenny Zhu

In this paper, we propose a length-aware attention mechanism (LAAM) to adapt the encoding of the source based on the desired length.

Reference-free Summarization Evaluation via Semantic Correlation and Compression Ratio

1 code implementation NAACL 2022 Yizhu Liu, Qi Jia, Kenny Zhu

In this paper, we propose a new automatic reference-free evaluation metric that compares semantic distribution between source document and summary by pretrained language models and considers summary compression ratio.

Improving Topic Relevance Model by Mix-structured Summarization and LLM-based Data Augmentation

no code implementations3 Apr 2024 Yizhu Liu, Ran Tao, Shengyu Guo, Yifan Yang

To tackle above two problems, we first take query concatenated with the query-based summary and the document summary without query as the input of topic relevance model, which can help model learn the relevance degree between query and the core topic of document.

Zero-shot Faithfulness Evaluation for Text Summarization with Foundation Language Model

1 code implementation18 Oct 2023 Qi Jia, Siyu Ren, Yizhu Liu, Kenny Q. Zhu

Despite tremendous improvements in natural language generation, summarization models still suffer from the unfaithfulness issue.

Taxonomy of Abstractive Dialogue Summarization: Scenarios, Approaches and Future Directions

no code implementations18 Oct 2022 Qi Jia, Yizhu Liu, Siyu Ren, Kenny Q. Zhu

Abstractive dialogue summarization is to generate a concise and fluent summary covering the salient information in a dialogue among two or more interlocutors.

Post-Training Dialogue Summarization using Pseudo-Paraphrasing

1 code implementation Findings (NAACL) 2022 Qi Jia, Yizhu Liu, Haifeng Tang, Kenny Q. Zhu

Previous dialogue summarization techniques adapt large language models pretrained on the narrative text by injecting dialogue-specific features into the models.

Multi-turn Response Selection using Dialogue Dependency Relations

1 code implementation EMNLP 2020 Qi Jia, Yizhu Liu, Siyu Ren, Kenny Q. Zhu, Haifeng Tang

In this paper, we propose a dialogue extraction algorithm to transform a dialogue history into threads based on their dependency relations.

Controlling Length in Abstractive Summarization Using a Convolutional Neural Network

1 code implementation EMNLP 2018 Yizhu Liu, Zhiyi Luo, Kenny Zhu

Convolutional neural networks (CNNs) have met great success in abstractive summarization, but they cannot effectively generate summaries of desired lengths.
