Papers with suicide ideation detection
Multi-Task, Multi-Channel, Multi-Input Learning for Mental Illness Detection using Social Media Text (D19-62)
Copied to clipboard
| Challenge: | Existing methods for mental illness detection have limited data available for training . lack of sufficient annotated data and inability to extract explanations on the derived outcome have restricted researchers to use traditional methods. |
| Approach: | They propose to use emotional patterns identified by clinical practitioners to enhance the prediction capabilities of a mental illness detection model built using a deep neural network architecture. |
| Outcome: | The proposed method achieves a task-specific AUC higher than 0.90 . it compares multi-task learning with multi-channel convolutional neural network and multiple inputs to methods such as multi-class classification . |
PHASE: Learning Emotional Phase-aware Representations for Suicide Ideation Detection on Social Media (2021.eacl-main)
Copied to clipboard
| Challenge: | Recent studies indicate that individuals exhibiting suicidal ideation increasingly turn to social media rather than mental health practitioners. |
| Approach: | They propose a time-and-phase-aware framework that adaptively learns features from a user’s historical emotional spectrum to contextualize suicidal intent. |
| Outcome: | The proposed framework outperforms state-of-the-art methods while outperforming existing methods. |
A Time-Aware Transformer Based Model for Suicide Ideation Detection on Social Media (2020.emnlp-main)
Copied to clipboard
| Challenge: | Suicide ideation is often linked to a history of mental depression. |
| Approach: | They propose a time-aware transformer based model for preliminary screening of suicidal risk on social media that augments linguistic models with historical context. |
| Outcome: | The proposed model outperforms competing models and shows that it is time-aware and contextually useful for suicide risk assessment. |
