Towards Modeling Role-Aware Centrality for Dialogue Summarization (2022.aacl-short)
Copied to clipboard
| Challenge: | Existing methods for dialogue summarization consider roles separately where interactions among different roles are not fully explored. |
| Approach: | They propose a novel role-aware centrality model to capture role interactions by involving role prompts to control what kind of summary to generate. |
| Outcome: | The proposed model achieves state-of-the-art on two public benchmark datasets, CSDS and MC. |

Improving Role-Oriented Dialogue Summarization with Interaction-Aware Contrastive Learning (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing methods for encoding dialogues do not capture interaction information between roles, thus ignore interaction-related key information. |
| Approach: | They propose a contrastive learning based interaction-aware model for the role-oriented dialogue summarization namely CIAM and use it to train the decoder to learn role-level interaction. |
| Outcome: | The proposed model captures interaction information between different roles and produces informative summaries on two public datasets. |

Structure-Aware Abstractive Conversation Summarization via Discourse and Action Graphs (2021.naacl-main)
Copied to clipboard
| Challenge: | Abstractive conversation summarization has received much attention, but it suffers from insufficient, redundant, or incorrect content due to the unstructured and complex characteristics of human-human interactions. |
| Approach: | They propose to model rich structures in conversations for more precise and accurate conversation summarization by incorporating discourse relations between utterances and action triples in utterrances and designing a multi-granularity decoder to generate summaries by combining all levels of information. |
| Outcome: | The proposed models outperform state-of-the-art methods and generalize well in other domains in terms of automatic evaluations and human judgments. |
