Ht-index is a head/tail breaks-induced index for characterizing hierarchical levels of fractals or geographic features in particular. Head/tail breaks is a newly developed classification scheme, as well as a visualization tool for data with a heavy-tailed distribution (Jiang 2013, Jiang 2015). The head/tail breaks partitions data values around their average or mean into a few big values in the head, and many small values in the tail, and this partition continues recursively for the head or the big values until the notion of far more small values than large values is violated. The number of times that far more small values than large ones recurs plus one is the ht-index.

Rank the citations of an author from the highest to the lowest, and one can easily compute the ht-index using this program: https://github.com/digmaa/HeadTailBreaks
Using my Google Scholar's citations, http://scholar.google.com/citations?user=ARKxYYUAAAAJ&hl=sv&oi=ao
I computed my ht-index that is 4; see the result below.
My h-index is 28, which means that I have maximum 28 publications that have been cited at least 28 times. The h-index looked at ONLY highly cited publications while ignore less cited ones. The less cited publications (which will be cited in the future) indicate the potentiality of a scholar. Unlike the h-index, the ht-index considers all publications (or publications cited at least once). In my case, my highest citation is 306, and the lowest citation 1 for my 118 publications recorded by Google Scholar. My ht-index indicates that the scaling pattern of far more less-cited publications than highly cited ones recurs three times.
I am curious about how effective the index is in capturing the impact of a scholar, in particular when compared to h-index and others similar. What is your ht-index?
