After a first analysis of the theme of personal security from a juridical point of view, the project focuses on citizens: which is the italian citizen's perception about crimes and uncertainty? How did it change in the course of time? What does it depend on?
The macro-aim of this part of the project is then to undestand and analize the possible links existing between the perception of personal security and the effective increase of criminality in our society.
The research starts from the definition of five indicators, chosen to observe on the web citizen's behaviour about personal security. Each indicator is antidote to a specific crime: (self defence devices, anti-theft alarms, security services, self defence courses, life and theft insurances). Does the offer of the product/service change proportionally to the increase (or decrease) of criminality?
Specific queries were used to select the first 200 results related to each product or service in Google and in 'Yellow Pages'. The 200 results were then 'cleaned' with Harvester, in order to obtain the pure url (returning hosts and uniques). The returning websites were checked with Google scraper, at a first level, and manually, at a second level, to figure out which websites were actually offering the considered product/service.
A range of 60-100 resulting url's for each indicator was obtained. Using the Wayback machine, it was possible to control when each website was born, the amount of updating per year and when the offer of the product/service started.
Results were compared to volume search for the same queries in Google, using Google Insight for Search.
The second part of the research foucuses on understanding links and relations between actors of the world of "security services" on the web.
With Navicrawler the list of urls was checked again in order to figure out which websites are linked together. Results were then visualized with Gephi: a complex and large net showing effective links between e-markets, portals and governamental institutions is the final result of this part of the research.
