Papers with abstractive summarization task
Enhancing Multi-Document Summarization with Cross-Document Graph-based Information Extraction (2023.eacl-main)
Copied to clipboard
| Challenge: | Information extraction (IE) and summarization (summarization) are closely related, but both aims to abstract the most salient information into a generated text summary. |
| Approach: | They propose to use structured IE graphs to enhance the abstractive summarization task by using cross-document IE output to incorporate an alignment loss between IE nodes and their text spans to reduce inconsistencies. |
| Outcome: | The proposed model can generate summaries that are more factual while not losing abstractiveness. |
Discrete Diffusion Language Model for Efficient Text Summarization (2025.findings-naacl)
Copied to clipboard
| Challenge: | Existing discrete diffusion models fail on conditional long-text generation due to incompatibility between the backbone architectures and the random noising process. |
| Approach: | They propose a semantic-aware noising process that enables Transformer backbones to handle long sequences effectively. |
| Outcome: | The proposed model outperforms existing models on three benchmark summarization datasets while achieving much faster inference speed compared to autoregressive models. |
AdaptSum: Towards Low-Resource Domain Adaptation for Abstractive Summarization (2021.naacl-main)
Copied to clipboard
| Challenge: | State-of-the-art abstractive summarization models rely on extensive labeled data, which lowers their generalization ability on domains where such data are not available. |
| Approach: | They propose to use domain adaptation methods to simulate the low-resource domain adaptation setting for abstractive summarization systems with existing datasets across six diverse target domains. |
| Outcome: | The proposed model can be used to adapt to a low-resource domain adaptation setting. |
Deep Reinforcement Learning with Distributional Semantic Rewards for Abstractive Summarization (D19-1)
Copied to clipboard
| Challenge: | Abstractive summarization tasks are often based on deep reinforcement learning (RL) but the traditional reward system Rouge-L simply looks for exact n-grams matches between candidates and annotated references, which makes the generated sentences repetitive and incoherent. |
| Approach: | They propose to use distributional semantics to measure matching degrees instead of Rouge-L to generate sentences with n-grams matches. |
| Outcome: | The proposed reward has superiority over the existing reward, despite the incoherence of the generated sentences. |
Multimodal Abstractive Summarization for How2 Videos (P19-1)
Copied to clipboard
| Challenge: | Abstractive summarization is a task of producing a shorter version of the content in the document while preserving its information. |
| Approach: | They propose a new evaluation metric that measures semantic adequacy rather than fluency of abstractive summarization tasks. |
| Outcome: | The proposed model integrates information from different sources into a coherent output. |
Enriching and Controlling Global Semantics for Text Summarization (2021.emnlp-main)
Copied to clipboard
| Challenge: | Abstractive summarization models have been proven effective in creating fluent and informative summaries, but they suffer from the short-range dependency problem, causing them to produce summary that miss the key points of document. |
| Approach: | They propose a neural topic model empowered with normalizing flow to capture global semantics of the document and integrate them into the summarization model. |
| Outcome: | The proposed model outperforms state-of-the-art summarization models on five common text summarizing datasets, namely CNN/DailyMail, XSum, Reddit TIFU, arXiv, and PubMed. |
