dc.description.abstract Substance abuse and mental health issues are severe conditions that affect millions. Signs of certain conditions have been traced on social media through the analysis of posts. In this paper we analyze textual cues that characterize and differentiate Reddit posts related to depression, eating disorders, suicidal ideation, and alcoholism, along with control posts. We also generate enhanced word embeddings for binary and multi-class classification tasks dedicated to the detection of these types of posts. Our enhancement method to generate word embeddings focuses on identifying terms that are predictive for a class and aims to move their vector representations close to each other while moving them away from the vectors of terms that are predictive for other classes. Variations of the embeddings are defined and evaluated through predictive tasks, a cosine similarity-based method, and a visual approach. We generate predictive models using variations of our enhanced representations with statistical and deep learning approaches. We also propose a method that leverages the properties of the enhanced embeddings in order to build features for predictive models. Results show that variations of our enhanced representations outperform in Recall, Accuracy, and F1-Score the embeddings learned with Word2vec , DistilBERT , GloVe ’s fine-tuned pre-learned embeddings and other methods based on domain adapted embeddings. The approach presented has the potential to be used on similar binary or multi-class classification tasks that deal with small domain-specific textual corpora.
