LTL-INAOE's Participation at eRisk 2019: Detecting Anorexia in Social Media through Shared Personal Information

Detecting mental-health risk behaviours at primary stages is crucial to bring help to people and to avoid undesired consequences. In this paper, we describe our participation at the eRisk 2019 shared task. The proposed approach mainly relies on analysing the sentences that include personal information, i.e., fragments of texts reflecting user’s interests, concerns, beliefs, personality traits and psychological state. The obtained results are very competitive, validating the important role of personal information for early detection of traces related to anorexia.
