Discovering relevant publications for researchers is a non-trivial task. Recommender systems can reduce the effort required to find relevant publications. We suggest using a visualization- and user-centered interaction model to achieve both a more trusted recommender system and a system to understand a whole research field. In a graph-based visualization papers are aligned with their keywords according to the relevance of the keywords. Relevance is determined using text-mining approaches. By letting the user control relevance thresholds for individual keywords we have designed a recommender system that scores high in accuracy (\(\bar{x}=5.03/6\)), trust (\(\bar{x}=4.31/6\)) and usability (SUS \(\bar{x}=4.89/6\)) in a user study, while at the same time providing additional information about the field as a whole. As a result, the inherent trust issues conventional recommendation systems have seem to be less significant when using our solution.
