The University of Maryland CLPsych 2015 Shared Task System

摘要

The 2015 ACL Workshop on Computational Linguistics and Clinical Psychology included a shared task focusing on classification of a sample of Twitter users according to three mental health categories: users who have self-reported a diagnosis of depression, users who have self-reported a diagnosis of post-traumatic stress disorder (PTSD), and control users who have done neither (Coppersmith et al., 2015; Coppersmith et al., 2014). Like other shared tasks, the goal here was to assess the state of the art with regard to a challenging problem, to advance that state of the art, and to bring together and hopefully expand the community of researchers interested in solving it.
