• Abstract: In recent years, cognitive and mental health (CMH) disorders have increasingly become an important challenge for global public health, especially the suicide problem caused by multiple factors such as social competition, economic pressure and interpersonal relationships among young and middle-aged people. Social media, as an important platform for individuals to express emotions and seek help, provides the possibility for early detection and intervention of suicide risk. This paper introduces a large-scale dataset containing 15,000 user-level posts. Compared with existing datasets, this dataset retains complete user posting time sequence information, supports modeling the dynamic evolution of suicide risk, and we have also conducted comprehensive and rigorous annotations on these datasets. In the benchmark experiment, we systematically evaluated the performance of traditional machine learning methods, deep learning models, and fine-tuned large language models. The experimental results show that our dataset can effectively support the automatic assessment task of suicide risk. Considering the sensitivity of mental health data, we also discussed the privacy protection and ethical use of the dataset. In addition, we also explored the potential applications of the dataset in mental health testing, clinical psychiatric auxiliary treatment, etc., and provided directional suggestions for future research work.
