Fractional counting of authorship to quantify scientific research output [article]

Vincenzo Carbone
2011 arXiv   pre-print
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.  ...

Contributory inequality alters assessment of academic output gap between comparable countries

Nils T. Hagen
2015 Journal of Informetrics  
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.  ...  Marshall for improving the style and flow of the manuscript, and thanks to the University of Nordland for providing a supportive work environment during data analysis and manuscript preparation.  ...

Fair ranking of researchers and research teams

2018 PLoS ONE  
The main drawback of ranking of researchers by the number of papers,  ...  Authorship-weighted counting This type of counting attempts to distribute credit between authors more properly than the simple fractional counting.  ...  By contrast, the fractional and authorship-weighted counting is sensitive to the number of co-authors of published papers.  ...

Bibliometrics for collaboration works [article]

Paolo Rossi, Alessandro Strumia, Riccardo Torre
2020 arXiv   pre-print
When counting citations we suggest the exponent α≈ 1, that corresponds to fractional counting.  ...  An important issue in bibliometrics is the weighing of co-authorship in the production of scientific collaborations, which are becoming the standard modality of research activity in many disciplines.  ...  The top-right panel of fig. 7 shows that h f exhibits the expected scale-invariant behaviour, and can thereby be used to quantify the scientific output of authors in a way that does not depend on their  ...

Towards Authorship Attribution for Bibliometrics using Stylometric Features

Andi Rexha, Stefan Klampfl, Mark Kröll, Roman Kern
2015 International Conference on Scientometrics and Informetrics  
In this paper, we aim at a more fine-grained analysis of scientific authorship.  ...  These results can be considered as an initial step towards a more detailed analysis of scientific authorship, thereby extending the repertoire of bibliometrics.  ...  Introduction Bibliometrics has had to face the ever growing amount of scientific output in recent years --a challenge as well as a great opportunity.  ...

A scientometrics law about co-authors and their ranking. The co-author core [article]

Marcel Ausloos
2013 arXiv   pre-print
Based on data about the publication output of a specific research group, a new bibliometric law is found. Let a co-author C have written J (joint) publications with one or several colleagues.  ...  Rather than "measuring" a scientist impact through the number of citations which his/her published work can have generated, isn't it more appropriate to consider his/her value through his/her scientific  ...  All scientific colleagues mentioned in the text have frankly commented upon the manuscript and enhanced its content .  ...

The h-index is no longer an effective correlate of scientific reputation

Vladlen Koltun, David Hafner, Sergi Lozano
2021 PLoS ONE  
We find that a fractional analogue of the h-index outperforms other measures as a correlate and predictor of scientific awards.  ...  The impact of individual scientists is commonly quantified using citation-based measures. The most common such measure is the h-index.  ...  This can ameliorate distortions introduced by contemporary authorship practices, lead to a more effective allocation of resources, and facilitate scientific discovery.  ...

2015 Canadian journal of physics (Print)  
Are existing ways of measuring scientific quality reflecting disadvantages of not being part of giant collaborations? How could possible discrimination be avoided?  ...  Based on the growing debate about defining potential biases and detecting unethical behavior, a standardized method to measure contributions of the astronomical number of coauthors is introduced.  ...  To quantify the estimate of an individual's scientific research output, we investigate the number of papers of three scientists, one experimentalist and two theoreticians during the last five years (Fig  ...
