Özet:

     In this study, classification models were implemented using natural language processing (NLP) methods to predict individuals' mental distress. The study utilized a labeled dataset of social media user comments, which included tags indicating the users' mental health status. Two different word representation approaches, Word2Vec and Term Frequency-Inverse Document Frequency (TF-IDF), were evaluated. To classify mental health status, models such as Naïve Bayes (NB), Support Vector Machine (SVM), K-Nearest Neighbors (KNN), and eXtreme Gradient Boosting (XGBoost) were applied. The results indicated that the XGBoost model, developed with data represented by TF-IDF, outperformed the other models.

     The methods employed, the models applied, and the findings of this study are expected to make significant contributions to further research in the fields of machine learning, natural language processing, and mental health. The results obtained may lead to advancements in predictive mental health monitoring systems and facilitate early intervention and support for individuals experiencing psychological distress.
