Towards NLP-based psychological evaluation.
This study considers methodology aimed at capturing subjective emotional properties of written texts. The range of possible applications would include forensic linguistics, psychological diagnosis, or political/cultural evaluations. As a measure of emotional text fluctuations we use entropy. For texts written under atypical mental conditions, the level of relative text entropy falls below a certain threshold and the distribution of entropy across the text shows unusual pattern, thus contributing to the evaluation of subjects mental state.
