DreamerNLplus: Interpretable Modeling of Mental Health Dynamics from Social Media Timelines using Hybrid Rule-Based and RAG Methods
The article presents DreamerNLplus, a hybrid framework designed to model mental health dynamics from social media timelines. It addresses three main tasks: psychological state modeling, temporal change detection, and sequence-level summarization. The findings highlight the complexities involved in modeling mental health dynamics and suggest areas for future research.
- ▪DreamerNLplus combines LLM-based data augmentation, DeBERTa classification, and Random Forest regression for structured state prediction.
- ▪The framework achieved strong performance in detecting psychological changes, ranking 1st for Improvement and 3rd for Deterioration.
- ▪Key challenges identified include the mismatch between classification and regression performance and difficulties in modeling temporal transitions.
