Researchers\u27 Scientific performance in ResearchGate: The Case of a Technology University

With the advancement of technology and changes made in the scientific communication model, changes have been made in scientific evaluation methods. New technologies offer indicators that measure all the actions and interactions of scientists in the digital environment and create new aspects of scientific communication. This work has some purposes; first, mapping profile of scientific activities of faculty members of Sharif University of Technology (SUT) in “ResearchGate” (RG), second, intend to test the correlation h-index between the RG and Web of Science (WoS) and Scopus and Google Scholar (GS). Third, investigate SUT faculty members’ top h cited research RG in WoS, Scopus, and GS. Fourth, investigate Altmetric score of SUT faculty members’ top h cited research RG with Altmetric Explorer (AE). For this purpose, the SUT faculty members were searched in RG. Information was noted for those who were members in RG. Then, all their h index and the number of citations of top h cited research were extracted from WoS, Scopus and GS. Altmetric scores of Top h cited research of SUT faculty members was obtained by using AE. The degree of correlation between RG h index and WoS h index was higher than the h index of other citation databases. Also, the results indicate that there are errors in the calculation of the Almetric score by AE. Only 3% of the top h cited research of SUT faculty members had Altmetric score. While 95.72% of them had been read at least once in Mendeley and 78.7% of them had been cited in Mendeley

Effect of Self-Citation on H-Index: A Study of Top 1% Highly Cited Iranian Scientists in Medical Sciences

Background: H-index is one of the main bibliometric indicators for evaluating researchers. It has been criticized due to the effect of self-citation rate on its increase. Aim: This study aimed at analyzing the state of top 1% highly-cited Iranian scientists in medical sciences in ESI for investigating the effect of their self-citations on their h-indices. Methods: Iranian Medical Science Scientometric Information Database, Essential Science IndicatorsTM (ESI) and Scopus indexing/abstracting database were used for data extraction. Data analysis was conducted in Excel and SPSS.. Results: In total, 6.15% of citations were self-citations that resulted in increase in h-index by 2.49 units. After excluding self-citations, the h-indexes of 23.4% of the studied scientists did not change and the mean rate of h-index decreased by 2.49. A correlational test showed the strong correlation between self-citation count and h-index rate (r=.718). Conclusion: Self-citation is present as a common phenomenon in all scientific communities and increases in h-index. If not used for manipulating bibliometric indicators, it can make the scientific works more visible for potential readers and consequently receiving more citations
