As wireless communication and mobile devicesadvances, recommendation system is one of the keytechnologies to realize personalized service. This paperproposes a service recommendation mechanism using aprobabilistic model in mobile devices. With the contextualinformation and the use's demand state inferred by the model, we can recommend a service to meet the user's preferencesand needs at real time. Finally, the model checking method is used to verify the reliability of the service composition recommended by the above method.
