Abstract
In this paper, the f-index is proposed as a new index in citation analysis that measures both the productivity and impact of the published work of a scientific researcher. Firstly, the definitions of hindex and g-index are shortly revisited. Next, a new index f-index for citation analysis is proposed and then some properties of f-index are investigated. The relationships between f-index and some other bibliometric indicators (such as h-index and g-index) are discussed. Finally, we conclude this paper with some remarks.
Keywords: Informetrics, Bibliometric analysis, F-index, G-index, H-index
1 Introduction
In the last few years, many new bibliometric rankings or indices have been proposed for comparing the output of scientific researchers. Among them, the most famous one is ft-index, an index that measures both the productivity and impact of the published work of a scientific researcher. The ft-index (Hirsch, 2005) is a tool that is increasingly used to measure individual research productivity. Moreover, the ?-index can also be applied to the productivity and impact of a group of scientific researchers, such as a department or university or country, as well as a scholarly journal.
The g-index (Egghe, 2006) is very similar to the ft-index, and attempts to address the shortcomings of ?-index. Moreover, there are many bibliometric indicators, such as ?-o-index (Banks, 2006), generalized ?index (Sidiropoulos et al., 2007), Hirsch-type indices (Prathap, 2006), ftp-index (Alonso et al., 2010), and extension of ft-index (Garcia-Perez, 2009), to study quantitative aspects of recorded information. All the above mentioned indices are belong to citation analysis, or bibliometrics, a branch of informetrics (Bar-Ilan 2008; Garfield, 1983; Rubin, 2004).
The ft-index has received an enormous attention for being an indicator that measures the quality of a researcher and an organization (Glänzel, 2006). The ft-index was intended to address the main disadvantages of other bibliometric indicators, such as total number of papers or total number of citations. Total number of papers does not account for the quality of scientific publications, while total number of citations can be disproportionately affected by participation in a single publication of major influence. The ft-index is intended to consider simultaneously the quality and quantity of scientific output, as well as, to some extent, the diversity of scientific research. The ?-index serves as an alternative to...
