Abstract(in English) | Depression is a prevalent mental health disorder that can have a significant impact on an individual's well-being. Therefore, early detection and treatment is crucial for symptom management. Recently, social media platforms have emerged as a valuable source of data for mental health research, and machine learning techniques can be employed to analyze text to identify potential signs of depression. In this study, we present a model for detecting depression based on Twitter data, which has high usage rates in Japan. We utilized the morphological analyzer Juman++ and an LDA (Latent Dirichlet Allocation) topic model to summarize Japanese tweets. User activity information was also integrated into the feature set. By testing morphological analyzers and the number of words in the dictionary, our model made improvements upon previous models [1]. Our analysis of the tweet and user features revealed that individuals with depression tend to tweet about lifestyle, work, and negative mental states. Furthermore, depressed individuals tended to post more tweets during nighttime, possibly indicating the presence of insomnia. |
