A Health Recommeder System to Tailor Message Preferences in a Smoking Cessation Programme

Patients in a smoking cessation program will use a mobile application to receive messages and rate them from their smartphones. The messages patient will receive belong to one of the following five topics: general motivation, diet tips, physical exercise tips, personal performance, and the benefits of being a non-smoker. For each one of these topics, there will be a pool of 150 different messages with tailored information for the patient. Topics and messages were approved by a smoking cessation psychologist and a pulmonologist. The selection of the time the messages have to be sent, and the message topic is selected by an health recommender system algorithm based on the patients' user profile (demographic information, message rating information, and app interaction information).
