A study on rating services based on users' categories

In the Internet age, people are becoming more and more familiar in experiencing
online services. In many cases, the customer commits herself and her assets in
a business transaction with no (or limited) possibility to test the
service/good she is booking/buying.  Hence, there is the need to prove the
trustworthiness of such services for supporting a user in her choice. Many
websites feed the customer with reviews of past users representing their degree
of satisfaction.  In this paper, we consider a scenario where different
services may be grouped together to form packets, and we design and implement a
simple procedure through which a customer can choose the packet that best
satisfies her expectations. The final choice will be driven both by the
qualities of the reviews on the constituting services, and by the customer's
personal preference and attitudes. To automatise the procedure, we survey real
behaviours of users when they choose a service and give reviews, by obtaining a
probabilistic model plugged in our simulator.  In particular, we deal with the
issue of false review, reported by unfair users that intentionally act
malevolently. The simulations results show that our system is robust enough up
to a certain number of unfair feedback.
