Most publications of Context-Aware Recommender Systems (CARS) do not follow a Software Engineering process while building their systems, rather they focus on proposing and testing algorithms. We believe that CARS can be built following a structured development process, therefore this paper reviews Context-Aware Recommender System literature, identify the(More)
