Emotional reactions to risk perception in the Herculaneum Archaeological Park

Abstract

The evaluation of perceived risk by people is particularly valuable for safety and security management. Each person is based on the opinion of others to make a choice and the Internet embodies the place where these opinions are mainly researched, found, and reviewed. Social networks have a significant impact: 92% of consumers declare they trust more of social media reviews than in any other form of advertising. For this reason, Opinion Mining and Sentiment Analysis have found noteworthy uses in different context, among which the most advanced is surely represented by public safety and security. Security managers can use the perceptions communicated by people to find the unpredicted and possible faults of a monitored environment or anyway the risk and security perception of people that sometimes can be truly diverse from real level of risk and security of a given site. Since the perceptions are the effect of mostly unconscious elaborations, it is necessary to go deeper and to search for the emotions, triggered by the sensorial stimuli, that define them.
