Role of the CWB-RS in the Companion. CWB-RS will process the content generated by the users of the educationally managed social media and the content externally recommended for them by the RSs of the external social media platform to create new recommendations aimed at maximizing the cumulative long-term collective well-being metric. Content Analyzers and Threat Detectors will analyze and evaluate the level of threat for each piece of content and other relevant information as the users' emotional state. This information will be used to: 1) augment the information provided to the users by the companion interface; 2) evaluate through predictive models of users' opinions and reactions the future effects of different sequences of re-ranking and recommending actions; 3) select the re-ranking and recommending actions that resulted in the highest expected cumulative improvement in terms of learning objectives, CWB metrics, agreement with selected educational strategies and user engagement.
