| Challenge: | a dataset of document grounded conversations provides information on content of a document . current datasets lacking conversation grounding do not provide this information . |
| Approach: | They propose a document grounded dataset for conversations . they use Wikipedia articles about popular movies to define document grounded conversations based on their results . |
| Outcome: | The proposed dataset provides a source of information and provides benchmark performance on the task of generating the next response. |

Copied to clipboard
| Challenge: | Existing work treats document-grounded dialogue modeling as a machine reading comprehension task based on a single document or passage. |
| Approach: | They propose a task and dataset for modeling goal-oriented dialogues grounded in multiple documents. |
| Outcome: | The proposed task and dataset address realistic scenarios where goal-oriented dialogues involve multiple topics and hence are grounded on different documents. |
Image-Chat: Engaging Grounded Conversations (2020.acl-main)
Copied to clipboard
| Challenge: | In order for machines to communicate with humans, they must understand the natural things that humans say about the world they live in and respond in kind. |
| Approach: | They propose to fuse a set of neural architectures using image and text representations to achieve this goal. |
| Outcome: | The proposed model performs well on the Image-Chat task and humans prefer it 47.7% of the time. |

Incremental Transformer with Deliberation Decoder for Document Grounded Conversations (P19-1)
Copied to clipboard
| Challenge: | Existing dialogue systems do not exploit document knowledge effectively enough. |
| Approach: | They propose a Transformer-based architecture for document grounded conversations that incorporates document knowledge into a two-pass decoder to improve context coherence and knowledge correctness. |
| Outcome: | The proposed model outperforms baselines on context coherence and knowledge relevance on a real-world document grounded dataset. |
Towards Exploiting Background Knowledge for Building Conversation Systems (D18-1)
Copied to clipboard
| Challenge: | Existing dialog datasets contain a sequence of utterances without any explicit background knowledge associated with them. |
| Approach: | They propose to use movie chats to generate responses by copying unstructured background knowledge . they use a dataset of 9K conversations to test whether responses are generated by copy-and-modify models . |
| Outcome: | The proposed model mimics human process of conversing by copying and/or modifying sentences from unstructured background knowledge. |
The PhotoBook Dataset: Building Common Ground through Visually-Grounded Dialogue (P19-1)
Copied to clipboard
| Challenge: | Using the PhotoBook dataset, we investigate shared dialogue history accumulating during conversation . human interlocutors are known to collaboratively establish a shared repository of mutual information during a conversation - this common ground is then used to optimise understanding and communication efficiency. |
| Approach: | They propose a data-collection task formulated as a collaborative game prompting two online participants to refer to images utilising both their visual context and previously established referring expressions. |
| Outcome: | The proposed model takes into account shared information accumulated in a reference chain and is important to resolve later descriptions. |
Action-Based Conversations Dataset: A Corpus for Building More In-Depth Task-Oriented Dialogue Systems (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing goal-oriented dialogue datasets focus on identifying slots and values, but in reality, customer service agents follow multi-step procedures derived from explicit company policies. |
| Approach: | They propose to use a fully-labeled dataset to study customer service dialogue systems in real-world scenarios. |
| Outcome: | The proposed dataset outperforms existing models but still lacks 50.8% absolute accuracy to reach human-level performance on the dataset. |
