Topic - Aim organization

Recommender Systems facilitate users' decision making when confronted with complex choice situations by easing the information overload. Technically, Recommender Systems have their roots in different fields such as Information Retrieval, Text Classification, Machine Learning and Decision Support Systems. The course will therefore offer first an introduction to the topic and is open to integrate similar and related topics deriving from PhD projects of participants. The course seeks to provide a comprehensive survey on the state-of-the-art and open research challenges in the recommender system field and therefore includes collaborative and content-based filtering methods (with a particular emphasis on the exploitation of Topic Models) as well as knowledge-based recommendation approaches. Furthermore the course will focus on how to measure and evaluate the efficiency and effectiveness of such systems covering the spectrum of seeing them as technical ranking algorithms and as methods for consumer decision support. Therefore, we will consider research designs from a conceptual perspective and compare them with good assessment practices in other research disciplines like Information Retrieval, Machine Learning or Decision Support Systems. Finally, the course will also cover aspects of making the interaction with personalization mechanisms more transparent to their users and the effects of decision biases in online choice situations.
