Bibliometric indices for the assessment of the citation curve tail

Scientometrics is an area recently attracting greater research interest. To a great extent this area has been fertilized by the proposal of the h-index (2005), which represents a measure for the quality and quantity of a researcher's impact. The Perfectionism Index has been recently proposed aiming at differentiating between 'influentials' and 'mass producers' (2015); the former category produces articles, which are (almost all) with high impact, whereas the latter category produces a lot of articles with moderate or no impact at all. In this paper, we record a number of metrics that are of similar nature, i.e. they shed light into these publishing patterns (influentials vs. mass producers). We carry out a correlation analysis to reveal which metrics are describing the above phenomenon in a similar way and, thus, retain the most descriptive features. Finally, we report the results of an experiment with a dataset consisting of the academic staff of Greek Computer Science/Engineering departments.
