We propose a geometric interpretation to the ranking of patent assignees by their h-indices as indicating the relative positions of their rank-citation curves. We then propose two shape descriptors characterizing the rank-citation curves over the h-cores and h-tails, respectively. Together with...

We propose a novel yet practical method capturing an individual's research or innovation performance by the shape centroids of the h-core and h-tail areas of its publications or patents. A large number of individuals’ relative performance with respect to their h-cores and h-tails can be...
