I want to know the current state of research regarding 'data mining in psychiatry (especially in analyzing and evaluating mental disorders)'. Is there any work that makes use of social media data ?
In psychiatry, the most impressive data mining researchers imo are Stefan Leucht (Munich) and Jari Tiihonen (now Karolinska). I should add I have no personal connection with either of these two academics.
However, on a personal note you could access my own paper on early death in the mentally ill (see my site) as an example of the Scottish data mines.
