活动简介:

Depression is a common mental disorder involving a depressed mood or loss of pleasure for long periods of time, which induces grave financial and societal ramifications. Social media-based depression detection is an effective method for early intervention to mitigate those consequences. Such a high-stake decision inherently necessitates interpretability. Although a few studies explain this decision based on the importance of input features, these explanations misalign with the depression diagnosis criteria that are based on depressive symptoms. To fill this gap, we develop a novel Focused Temporal Prototype Network (FTPNet) to detect depression and interpret depressive symptoms as well as how often they occur. Extensive empirical analyses using large-scale datasets show that FTPNet outperforms comprehensive benchmark methods with an F1-score of 0.864. Our result also reveals new symptoms that are unnoted in the survey approach, such as sharing admiration for a different life. We further conduct a user study to demonstrate improved interpretability over the benchmark. This study contributes to Information System (IS) literature with a novel interpretable depression detection method in social media. In practice, our proposed method can be implemented in social media platforms to provide personalized online resources for detected depressed users.
