In the analysis of digital content consumption, session progress provides a good alternative to using manual ratings for measuring user engagement. A good prediction of session progress is useful for optimizing and personalizing the end-user experience. Most prevalent methods of predicting session progress are based on matrix completion and only consider the interaction among users and videos, while the associated contextual information is usually not used. In this paper, we present our approach for video recommendation, based on session progress prediction and incorporating the context. We test our approach on real-world session progress data, and observe considerable improvement in prediction accuracy achieved by incorporating selected context. Our experiments also show that proper context selection and the number of observed sessions for users are two key factors affecting the prediction accuracy.
