  Providing personalized recommendations that are also accompanied by
explanations as to why an item is recommended is a research area of growing
importance. At the same time, progress is limited by the availability of open
evaluation resources. In this work, we address the task of scientific
literature recommendation. We present arXivDigest, which is an online service
providing personalized arXiv recommendations to end users and operates as a
living lab for researchers wishing to work on explainable scientific literature
recommendations.
