A hybrid deep learning framework for multilingual depression detection and symptom classification from social media text
摘要
Detecting depression in low-resource and code-mixed social media text remains highly challenging, due to scarcity of annotated datasets and complexity of mixed language pattern. The study presents Multi-MentalBERT, a hybrid deep learning framework to perform dual-level multi-class classification across code-mixed and monolingual datasets. It first classifies the text as depressive, non-depressive or neutral, and then predicts the specific Major Depressive Disorder (MDD) category for each depressive instance. The framework integrates multilingual contextual features from MuRIL with mental health specific embeddings of MentalBERT through Cross-Attention fusion, supported by Hierarchical attention and Deep Joint Autoencoder to create a unified representation learning. The framework achieved a macro F1-score of 91.03% for three-class depression detection and 87.75% for MDD classification on Kannada-English dataset, and obtained 95.87% macro F1-score for MDD classification on English Reddit depressive dataset. The result outperforms the baseline models and demonstrates the effectiveness of the approach in automated mental health analysis across linguistic boundaries.
