If such applications cannot find a solution, repair actions are proposed that provide support for getting out of the so-called “no solution could be found” dilemma. Such repairs are not personalized and thus often cause a low level of satisfaction and cancellations of sessions. In this work we introduce a personalized repair algorithm that integrates the concepts of model-based diagnosis with collaborative recommendation approaches. For demonstration purposes, we present the results of a study that show improvements in prediction accuracy when personalized repair actions are proposed.
