- Abstract: Explanations are used in recommender systems for various reasons. Users have
to be supported in making (high-quality) decisions more quickly. Developers of
recommender systems want to convince users to purchase specific items. Users
should better understand how the recommender system works and why a specific
item has been recommended. Users should also develop a more in-depth
understanding of the item domain. Consequently, explanations are designed in
order to achieve specific \emph{goals} such as increasing the transparency of a
recommendation or increasing a user's trust in the recommender system. In this
paper, we provide an overview of existing research related to explanations in
recommender systems, and specifically discuss aspects relevant to group
recommendation scenarios. In this context, we present different ways of
explaining and visualizing recommendations determined on the basis of
preference aggregation strategies.

It is crucial for all stakeholders to understand the model's rationale behind making certain predictions and recommendations.
This is especially true for the content providers whose livelihoods depend on the recommender system.
We propose a recourse framework for recommender systems, targeted towards the content providers.

Recent work has shown that feedback loops may compromise recommendation quality and homogenize user behavior.
We propose the Causal Adjustment for Feedback Loops (CAFL), an algorithm that provably breaks feedback loops using causal inference.
We show that CAFL improves recommendation quality when compared to prior correction methods.

We analyze different groups of users according to their level of activity, and find that bias exists in recommendation performance between different groups.
We show that inactive users may be more susceptible to receiving unsatisfactory recommendations, due to insufficient training data for the inactive users.
We propose a fairness constrained approach via re-ranking to mitigate this problem in the context of explainable recommendation over knowledge graphs.
