A Survey on Co-authorship Network among the Researchers in the Field of Dentistry in Tehran City, Iran, in Thompson Reuter's Web of Science, and Scopus Databases during 2011-2015

Co-authorship network is a kind of social network that offers significant information about collaboration among authors, which is one of the most important factors of the qualitative and quantitative growth of the scientific publications. The results of this study can clarify the dimensions of collaboration in dental schools in Tehran City, Iran, between the years 2011 and 2015 based on the data in Thompson Reuter’s Web of Science and Scopus databases.
The study was conducted through scientometrics method and social network analysis. The research community consisted of 802 documents indexed in the Scopus and Thompson Reuter’s Web of Science databases published in years 2011-2015.
The majority of collaborations made by Iranian researchers were with the authors from the United States, the United Kingdom, and Turkey. Co-authorship network of researchers consisted of 60 nodes (authors) and density degree of the network was 0.028. There was a strong linear correlation between the number of publications and degree centrality of authors at the level of 0.73.
The results seem to indicate more collaborative research and an increase in the overall production of articles with this cooperation growing at an appropriate level. This suggests that researchers in this field are aware of the benefits of scientific cooperation.
