Fractional counting of authorship to quantify scientific research output
[article]
2011
arXiv
pre-print
Preserved Fulltext
We investigate the problem of counting co-authorhip in order to quantify the impact and relevance of scientific research output through normalized h-index and g-index. ...
We show that, in order to remove the dependence of the various indices on the two populations, the best way to define a fractional counting of autorship is to divide the number of citations received by ...
Acknowledgments: I'm very grateful to C. Basile and S. Donato who provided a partial dataset used in the paper. I'm grateful to P. Veltri and R. Bartolino for fruitful discussions. ...

An elite segment of the academic output gap between Denmark and Norway was examined using harmonic estimates of publication credit for contributions to Science and Nature in 2012 and 2013. ...
Concurrently, the credit produced by the least productive half of the contributions rose tenfold from 0.9% to 10.1% for Norway, but dropped from 7.2% to 5.7% for Denmark. ...
