Sentiment Analysis: Applicazione in un dominio psico-forense

This study aims to apply the sentiment analysis to a psycho-forensic context through the analysis of narrative transcriptions related to the crimes committed by violent detainees. We investigate the presence of psychopathy through the Psychopathic Personality Inventory-Revised (PPI-R). Psychopathy is a personality disorder that is characterized by emotional detachment, the lack of empathy and it is often found in the prison population for the brutality of committed crimes. Our study explores possible associations between psychopathy and emotional content present in the narratives. Results show a neutral polarity for both psychopathic and not psychopaths offenders, however it is possible to identify significant emotional characteristics that diversify the narrative transcriptions.
