Abstract
There are several well-known methodologies for determining the ranking of authors. These methodologies could be classified into two major groups; one is single-authored index, in this group, it does not take into consideration the number of co-authors in one single publication; the other is multi-authored index. Since papers with multi-authors tend to get more citations, indexes in this group propose some solutions to evaluate a single author’s index alone, without other co-authors. This is the so called multi-authored problem.
In this paper, we proposed a novel methodology for author ranking; we called it hex-index. We made improvements both in single-authored index and multi-authored index. In single-authored index, we have more resolution than the h-index, the most popular index for author ranking around the academic world. And in multi-authored index, we provide more reasonable measurements for the contribution of each author in one publication. In addition, our method not only could calculate an author’s index excluding all co-authors, but also could measure his or her index when excluding a portion of the co-authors.
We collected data from DBLP and Google Scholar, including each author’s publications, co-authors and citation records. From this dataset, we sampled two hundred authors, and we discovered the fact that for authors with higher h-index, their hex-index would slightly bigger than hm-index, the famous multi-authored index.
