Design and Evaluation of Recommender Systems
Abstract: Recommender Systems (RSs) help users search large amounts of contents by allowing them to identify the items that are likely to be more attractive or useful. RSs play an important role in many domains (e.g., e-commerce, e-tourism, entertainment), as they can potentially augment the users’ trust towards an application and orient their decisions or actions towards specific directions. The goal of this lecture is to give participants a solid background of how to design and evaluate RSs, with a focus on user experience aspects, and to provide pragmatic guidelines to perform these activities more effectively. The lecture is structured into two parts. The first part will provide a general overview of recommender systems and their design issues. The second part will analyze “off-line” (system-centric) evaluation techniques.
