The UMD CLPsych 2016 Shared Task System: Text Representation for Predicting Triage of Forum Posts about Mental Health

We report on a multiclass classifier for triage of mental health forum posts as part of the CLPsych 2016 shared task. We investigate a number of document representations, including topic models and representation learning to represent posts in semantic space, including contextand emotion-sensitive feature representations of posts.
