Histogram of ranking position by citation counts (CC) and saliencies (top) and their differences (bottom). Although future citation counts are the target for best estimating the saliencies, they only agree on the publication rankings roughly 80 percent of the time, demonstrating the effects of non-citation factors (Figure 3) in the design of saliency. In contrast to citation counts, saliencies are sensitive to the venues, the authors, the concepts, and the recencies of the citing sources.
