- 87 abstract "Recommender systems play an important role in support- ing people when choosing items from a overwhelming huge number of choices. So far, no recommender system makes use of domain knowledge. We are modeling user prefer- ences with a machine learning approach to recommend peo- ple items by predicting the item ratings. Specifically, we pro- pose SemTree, an ontology-based decision tree learner, that uses a reasoner and an ontology to semantically generalize item features to improve the effectiveness of the decision tree built. We show that SemTree outperforms comparable ap- proaches in recommending more accurate recommendations considering domain knowledge.".
