Semantic Space Grounded Weighted Decoding for Multi-Attribute Controllable Dialogue Generation (2023.emnlp-main)
Copied to clipboard
| Challenge: | Controlling chatbot utterance generation with multiple attributes is a useful but under-studied problem. |
| Approach: | They propose a framework that possesses strong controllability with a weighted decoding paradigm and improves generation quality with an attribute semantics space. |
| Outcome: | The proposed framework achieves high control accuracy with simultaneous control of 3 aspects while producing interesting and sensible responses even in an out-of-distribution robustness test. |
Detection of Multiple Mental Disorders from Social Media with Two-Stream Psychiatric Experts (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing mental disease detection methods are not backed by domain knowledge and thus fail to produce interpretable results. |
| Approach: | They propose a framework that can learn the shared clues of all diseases while also capturing the specificity of each single disease. |
| Outcome: | Experiments on the detection of 7 diseases show that the proposed model can boost detection performance by more than 10%, especially in relatively rare classes. |

| Challenge: | Existing studies focus on the semantic content of social media posts, overlooking the evolving nature of mental disorders and symptoms. |
| Approach: | They extract causality between psychiatric symptoms and life events from social media posts and extract temporal attributes to improve diagnosis and treatment planning. |
| Outcome: | The extracted causality features improve diagnostic and treatment planning and improve performance in tasks such as depression and diagnosis point detection. |
Symptom Identification for Interpretable Detection of Multiple Mental Disorders on Social Media (2022.emnlp-main)
Copied to clipboard
| Challenge: | Mental disease detection (MDD) from social media has suffered from poor generalizability and interpretability due to lack of symptom modeling. |
| Approach: | They propose to annotate a social media corpus of symptom classes related to 7 mental disorders using a knowledge graph and a new annotation framework to facilitate further research. |
| Outcome: | The proposed model outperforms strong pure-text baselines and provides convincing MDD explanations with case studies. |
