Aim: The aim of this article was to study the scientific outputs of Semnan university researchers in term of quantitative indexes (number of outputs, research area, and year) and qualitative indexes (number of citations and H-Index). Mapping the co-author network of Semnan university researchers in the Web of Science database was the other purpose of the present paper.
Methodology: The research was conducted based on scientometric methods. The research population included all the documents which mentioned Semnan University as their affiliation and were indexed in Web of Science from 1990 to 2015. Totally, 2106 documents were indexed in this timespan. The co-author network was mapped and analyzed by Coau.exe, Ucinet and Netdraw.
Results: The results showed that Engineering (39%), Physics (19.5) and Mathematics (14%) were the subjects to which Semnan university researchers contributed. Totally, in the time span investigated, Iranian researchers produced 272019 documents out of which 2106 belonged to Semnan University. Therefore, this university ranked 30 among the Iranian universities. During the period studied, Semnan University produced 0.0049% of the universal scientific outputs. The results of the growth rate calculation indicated 43.22 for Semnan University researchers in the past fifty years that reveals a promising rising growth rate. Amjadi, Gorji and Orouji with 25, 23 and 15 H-Indexs ranked first to third, respectively. In term of citation, Amjadi ranked first with 2126 citations and Gorji with 1341 and Orouji with 629 citations were in the next ranks. Investigating the degree from among the centrality measurements was also calculated and the results showed that Gorji, Fereydoun and Asghari were in the top. The highest co-authoring rate occurred in 2005 which included 3 authors. As regards the fields of study, mathematics was the highest single-author subject.
Conclusion: The results of data analysis showed that, although the flow of co-authorship among the Semnan University researchers has fluctuated in recent years, during the studied period, the researchers of Semnan University have tended to write co-authorship. Generally, documents with three authors were the most co-authorship.
