Abstract
Providing useful recommendations is an important challenge for user-centric media systems. Whereas current recommender systems research mainly focuses on predictive accuracy, we contend that a truly user-centric approach to media recommendations requires the inclusion of user experience measurement. For a good experience, predictive accuracy is not enough. What users like and dislike about our systems is also determined by usage context and individual user characteristics. We therefore propose a generic framework for evaluating the user experience using both subjective and objective measures of user experience. We envision the framework, which will be tested and validated in the large-scale field trials of the FP7 MyMedia project, to be a fundamental step beyond accuracy of algorithms, towards usability of recommender systems.
