“…There is a close relation between random walks with sinks/sources and currents in electric networks-for details see [41,42]. PageRank augmented with sinks was shown to increase the diversity of top ranked items [43]. After the top ranked object is found by ordinary PageRank computation, it is turned into a sink and the second object is selected from the remaining transient nodes as the one that has the longest time to absorption.…”

“…• Diversity methods: several diversity promotion methods have been proposed, including function-based [31,62], graph-based [127], and clustering methods [28]. These methods may be found adequate for different scenarios and should also be considered.…”
