Papers with coherence model
Coherence Modeling of Asynchronous Conversations: A Neural Entity Grid Approach (P18-1)
Copied to clipboard
| Challenge: | Existing coherence models are not able to distinguish coherent discourses from incoherent ones. |
| Approach: | They propose a novel coherence model for written asynchronous conversations . they propose to lexicalize the model's entity transitions and extend it to asynchron conversations based on conversational structure . |
| Outcome: | The proposed model outperforms existing models on coherence assessment and thread reconstruction tasks. |

Peng Xu, Hamidreza Saghir, Jin Sung Kang, Teng Long, Avishek Joey Bose, Yanshuai Cao, Jackie Chi Kit Cheung
| Challenge: | Existing coherence models do not generalize to unseen categories of text . previous work advocates for generative models for cross-domain generalization . |
| Approach: | They propose a local discriminative neural model with a smaller negative sampling space that can discriminate against incorrect orderings. |
| Outcome: | The proposed model outperforms state-of-the-art methods on a standard benchmark dataset on the Wall Street Journal corpus and multiple challenging settings on Wikipedia articles. |
Rethinking Self-Supervision Objectives for Generalizable Coherence Modeling (2022.acl-long)
Copied to clipboard
| Challenge: | Prior work on text generation models focused on new architectures for permuted document tasks. |
| Approach: | They propose to use a basic model architecture to improve coherence evaluation of machine generated text. |
| Outcome: | The proposed model improves on a task-independent test set and shows significant improvements in coherence evaluations of downstream tasks. |
Sentence Ordering with a Coherence Verifier (2023.findings-acl)
Copied to clipboard
| Challenge: | Recent sentence ordering studies can be classified into 2 categories: pair-wise ranking-based and sequence generation-based methods. |
| Approach: | They propose a sentence ordering method by plugging a coherence verifier into ranking-based and sequence generation-based methods. |
| Outcome: | The proposed method improves on topological sorting-based and pointer network-based methods with topological and point-based models. |
Incremental Neural Lexical Coherence Modeling (2020.coling-main)
Copied to clipboard
| Challenge: | Recent work on pretrained language models has led to significant improvements in a range of NLP tasks. |
| Approach: | They propose a coherence model which interprets sentences incrementally to capture lexical relations between them. |
| Outcome: | The proposed model interprets sentences incrementally to capture lexical relations between them. |
Centering-based Neural Coherence Modeling with Hierarchical Discourse Segments (2020.emnlp-main)
Copied to clipboard
| Challenge: | Prior studies of coherence focused on identifying semantic relations between adjacent sentences. |
| Approach: | They propose a coherence model which takes discourse structural information into account without relying on human annotations. |
| Outcome: | The proposed model performs state-of-the-art on automated essay scoring and assessing writing quality tasks. |
