RG (ResearchGate Score)

The RG Score is a metric that measures scientific reputation based on how all of your work is received by your peers. We believe that fellow researchers are the best judges of each other's work, and that all your research, published or not, deserves credit. With this in mind, your RG Score is based on how both your published research and contributions to ResearchGate are received by your peers.

A contribution is anything you share on ResearchGate or add to your profile, from published papers and questions and answers, to negative results and raw data. Our algorithm looks at how your peers receive and evaluate your contributions and who these peers are. This means that the higher the scores of those who interact with your research, the more your own score will increase.

In contrast to more traditional metrics, the RG Score focuses on you, an ever-growing community of specialists, and puts reputation back into the hands of researchers.

h-index score

The h-index is calculated based on two bits of information: the total number of papers published (Np) and the number of citations (Nc) for each paper. It is defined by how many h of a researcherís publications (Np) have at least h citations each. This means that if you have one publication with at least one citation, your h-index is 1, if you have two publications with at least two citations each, your h-index would be 2, and so on.

On ResearchGate, you'll see two separate h-indices displayed for each author. The first metric is an h-index that includes self-citations. The second h-index displayed excludes self-citations so that anyone looking at the numbers can compare them and quickly gauge whether other authors are paying attention to a researcher's work.

Please note: The h-index takes into account only citations of your work from scientific literature, reflecting impact in the scientific community. Furthermore, it is calculated based on the publications in your profile.
