KdConv: A Chinese Multi-domain Dialogue Dataset Towards Multi-turn Knowledge-driven Conversation (2020.acl-main)
Copied to clipboard
| Challenge: | Existing knowledge-driven dialog data is limited due to the lack of dialog data which consists of multi-turn conversations on multiple topics and with knowledge annotations. |
| Approach: | They propose a Chinese multi-domain knowledge-driven conversation dataset which grounds the topics in multi-turn conversations to knowledge graphs. |
| Outcome: | The proposed dataset can be enhanced by introducing background knowledge, but there is still a large space for leveraging knowledge to model multi-turn conversations for further research. |
CrossWOZ: A Large-Scale Chinese Cross-Domain Task-Oriented Dialogue Dataset (2020.tacl-1)
Copied to clipboard
| Challenge: | Despite the significant contributions to the community, there is still a gap between existing dialogue corpora and real-life human dialogue data. |
| Approach: | They propose to develop Chinese cross-domain wizard-of-oz task-oriented dataset CrossWOZ with rich annotations of dialogue states and dialogue acts on both user and system sides. |
| Outcome: | The proposed dataset contains 6K dialogue sessions and 102K utterances for 5 domains, including hotel, restaurant, attraction, metro, and taxi. |

| Challenge: | Existing RAG methods do not utilize hierarchical knowledge in human cognition, which limits the capabilities of RAG systems. |
| Approach: | They propose a graph-based approach that utilizes hierarchical knowledge to enhance the semantic understanding and structure capturing capabilities of RAG systems. |
| Outcome: | The proposed approach achieves significant performance improvements over the state-of-the-art methods. |
