A Subsymbolic Model of Schizophrenic Language (2010)
Author: Uli Grasemann
The DISCERN system is trained to paraphrase stories consisting of multiple scripts and including emotional content and self-reference; it is then lesioned in various ways to model possible underlying causes of schizophrenia. This demo allows the user to specify the lesions and their intensity, and observe the resulting impaired storytelling graphically and in individual stories.
