| Challenge: | Existing studies have generated nods from the final morphemes at the end of an utterance. |
| Approach: | They propose to generate head nods from Japanese dialogues using morphemes . they compile a corpus of 24 dialogues including utterance and nod information . |
| Outcome: | The proposed model outperforms a model using morpheme information in the Japanese language and shows that dialog acts can predict nods. |

Automatic Dialogue Generation with Expressed Emotions (N18-2)
Copied to clipboard
| Challenge: | a growing interest in neural dialogue generation systems is focusing on generating human-like responses based on past utterances . despite efforts, few consider putting restrictions on the response itself . authors present three models that concatenate the desired emotion with the source input . |
| Approach: | They propose three models that concatenate the desired emotion with the source input or push the emotion in the decoder. |
| Outcome: | The proposed model is more efficient than the previous models, but it lacks the emotion vector. |
Neural Generation of Dialogue Response Timings (2020.acl-main)
Copied to clipboard
| Challenge: | Using neural models, the timings of spoken response offsets in human dialogue can vary based on contextual elements of the dialogue. |
| Approach: | They propose neural models that simulate the distributions of response offsets taking into account the response turn as well as the preceding turn. |
| Outcome: | The proposed models can generate distributions of response offsets based on the response turn and preceding turn based upon human listening tests and offline experiments. |
Language Model as an Annotator: Exploring DialoGPT for Dialogue Summarization (2021.acl-long)
Copied to clipboard
| Challenge: | Existing dialogue summarization systems encode text with a number of general semantic features, but these are often not available in open-domain tools. |
| Approach: | They propose to use DialoGPT to label three types of features on two datasets . they propose to employ pre-trained and non-pre-tried models as dialogue annotators . |
| Outcome: | The proposed method improves on two dialogue summarization datasets and achieves state-of-the-art performance. |

Dialogue-Act Prediction of Future Responses Based on Conversation History (P19-2)
Copied to clipboard
| Challenge: | Sequence-to-sequence models are a common approach to develop chatbots, but they are prone to a black-box response generation process. |
| Approach: | They propose a method to predict a DA of the next response based on the history of previous utterances and their DAs. |
| Outcome: | The proposed model achieves 10.8% higher F1-score and 3.0% higher accuracy on DA prediction compared to baseline using only a single utterance . |
Explicit Use of Topicality in Dialogue Response Generation (2022.naacl-srw)
Copied to clipboard
| Challenge: | Existing chat dialogue systems only implicitly consider the topic given the context, but not explicitly. |
| Approach: | They propose a dialogue system that responds appropriately following the topic by selecting the entity with the highest “topicality” they define the entity as a noun or compound nouns, and topicality as the degree of speaker awareness directed toward each entity in the dialogue context. |
| Outcome: | The proposed system can follow the topic more than existing systems that only consider the context . |
Reimagining Intent Prediction: Insights from Graph-Based Dialogue Modeling and Sentence Encoders (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing approaches to intent prediction are limited in highly specialized fields, such as closed-domain dialogue systems, where context comprehension is of paramount importance. |
| Approach: | They propose a method that uses scenario dialog graphs to model dialogues as sequences of transitions between intents, representing distinct goals or requests. |
| Outcome: | The proposed method significantly advances the field of dialogue systems, providing valuable insights into the effectiveness and potential limitations of the proposed approaches. |
