In this paper, the authors have discussed the task, dataset, and results of the Linked Data Mining Challenge 2015. The submissions show that Linked Open Data is a useful source of information for data mining, and that it can help to build good predictive models. On the other hand, the experiment with majority voting shows that there is still some headroom for improvement. One problem to address in future editions is the presence of false predictors. The dataset at hand, originating from MetaCritic, averages several ratings on movies into a final score.
