Suicidal Ideation and Mental Disorder Detection with Attentive Relation Networks
share
Mental health is a critical issue in the modern society, mental disorders could sometimes turn to suicidal ideation without effective treatment. Early detection of mental disorders and suicidal ideation from social content provides a potential way for effective social intervention. Classifying suicidal ideation and other mental disorders, however, is a challenging task as they share quite similar patterns in language usage and sentimental polarity. In this paper, we enhance text representation with lexicon-based sentiment scores and latent topics, and propose to use relation networks for detecting suicidal ideation and mental disorders with related risk indicators. The relation module is further equipped with the attention mechanism to prioritize more important relational features. Through experiments on three real-world datasets, our model outperforms most of its counterparts.
