exploratory search? ...
In this paper, we investigate recommender systems from a network perspective and investigate recommendation networks, where nodes are items (e.g., movies) and edges are constructed from top-N recommendations ...
For small N s, node memberships vary. With increasing N , most of the nodes are in the largest strongly connected component (SCC).
