Sentiment Analysis: applicazione in un dominio psico-forense

Résumé En It

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.

Il presente studio ha l’obiettivo di applicare la sentiment analysis ad un contesto psico-forenseattraverso l’analisi di resoconti narrativi relativi ai crimini commessi da detenuti, autori di reati violenti. Attraverso lo strumento Psycopathic Presonality Interventory-Revised (PPI-R), è stata indagata la presenza di psicopatia, disturbo di personalità affettivo neutro sia per gli offender psicopatici sia per gli offender non psicopatici, tuttavia è possibile individuare peculiarità emotive significative che diversificano i resoconti narrativi.
