User reputation and data quality in a crowdsensing platform for impaired mobility

This dissertation project aims to deal with all these problems by proposing a platform to support people with reduced mobility. There are systems that deal with the problem of urban accessibility through sets of data provided by certified authorities. Such systems have the limit of not being updated in real time and do not extend the possibility of adding information to all participants. From this comes the idea of creating a new application. The application purpose is to collect information on urban accessibility from all users and guarantee, by applying the concept of crowd-sensing, a high level of data trustworthiness. To be effective in its goal, the application must be easy to use and accessible to everyone at anytime and anywhere. For this reason, the software will be developed around two must-haves that form the main basis for today's communication: Internet and smartphones.
