Description Uncertainty is prevalent in most recommendation systems. The inability to effectively present results of objects with scarce data remains an opportunity for investigation. This thesis investigates how items within a system lacking user reviews can be recommended in a content-based recommendation engine. This research contributes to the body of existing knowledge on uncertainty, recommendation systems, and participant experience. The results of this research are measured by determining participant trust given unexpected results provided by this recommendation system. The following research question is presented, which this thesis aims to answer: How does introducing uncertain results in a content-based/collaborative filtering hybrid recommendation system impact a participant's trust towards a recommendation system? In other words, this thesis addresses how uncertain results affect the participant. The results of this thesis proved to not be statistically significant. Each variable tested against the control showed similar results to one another. Participant scores were collected regarding their satisfaction and trust in the recommendation system. The scores showed no statistical significance between the different tests. Therefore, this thesis concludes different ways of displaying uncertain results does not improve their chance of satisfaction or use. Since the different ways of displaying uncertain results are not relevant, this suggests that simply showing uncertain results may be sufficient to overcome the bubble-up problem.
