CLPsych Shared Task
The Computational Linguistics and Clinical Psychology (CLPsych) workshop has hosted shared and unshared tasks for several years. In 2015 the shared task used data from Twitter users who state a diagnosis of depression or post traumatic stress disorder (PTSD) along with demographically-matched community controls. The shared task provided an apples-to-apples comparisons of various approaches to modeling language relevant to mental health from social media. The shared task consisted of three binary classification experiments: (1) depression versus control, (2) PTSD versus control, and (3) depression versus PTSD.
