Personality Based User Similarity Measure for a Collaborative Recommender System. Tkalčič, M., Kunaver, M., & Tasic, J. In Proceedings of the 5th Workshop on Emotion in Human-Computer Interaction - Real world challenges, 2009. Fraunhofer Verlag. abstract bibtex We propose a novel approach for calculating the user similarity for collaborative filtering recommender systems that is based on the big five personality model. Experimental results showed that the performance of the proposed measures is either equal or better (depending on the measure under evaluation) than the ratings based measures used in stateof-the-art collaborative recommender systems. This makes the proposed approach, with its benefits in terms of computational complexity, for calculating user similarities a very promising one for future collaborative recommender systems that will be more affect-oriented.
