Analysis and definition of the framework of quality determinants in the shared mobility sector

The idea of this study is to produce and examine the set of determinants relevant to the perception of the quality of some specific use-oriented PSS in the shared mobility sector. The methodology applied for the extraction of the quality dimensions of the services consists in the application of a topic modeling algorithm, the Structural Topic Modeling, to a database of reviews released by users. The application of the proposed approach drives to the definition of a framework of common quality dimensions for all sharing mobility services, starting from the evaluation and comparison of three separate services: car sharing, bike sharing and e-scooter sharing.
