A simple centrality index for scientific social recognition

Abstract

We introduce a new centrality index for bipartite network of papers and authors that we call KK-index. The KK-index grows with the citation performance of the papers that cite a given researcher and can seen as a measure of scientific social recognition. Indeed, the KK-index measures the number of hubs, defined in a self-consistent way in the bipartite network, that cites a given author. We show that the KK-index can be computed by simple inspection of the Web of Science platform and presents several advantages over other centrality indexes, in particular Hirsch hh-index. The KK-index is robust to self-citations, is not limited by the total number of papers published by a researcher as occurs for the hh-index and can distinguish in a consistent way researchers that have the same hh-index but very different scientific social recognition. The KK-index easily detects a known case of a researcher with inflated number of papers, citations and hh-index due to scientific misconduct. Finally, we show that, in a sample of twenty-eight physics Nobel laureates and twenty-eight highly cited non-Nobel-laureate physicists, the KK-index correlates better to the achievement of the prize than the number of papers, citations, citations per paper, citing articles or the hh-index. Clustering researchers in a KK versus hh plot reveals interesting outliers that suggest that these two indexes can present complementary independent information.
