A Taxonomy for Generating Explanations in Recommender Systems

Gerhard Friedrich, Markus Zanker


In recommender systems, explanations serve as an additional type of information that can help users to better understand the system's output and promote objectives such as trust, confidence in decision making or utility.

Finally, the authors present their view on open research issues and opportunities for future work on this topic.
