Introduction: Scientific co-operation is a process in which two or more authors share their resources and talents with the aim of creating a shared work. One of the forms of scientific co-operation is co-authorship that involves the production of a scientific output by several collaborative researchers and scholars. This research has been designed to map out co-authorship networks in the Hamadan University of Medical Sciences researches indexed in the Web of Science from 2012 to 2016, and analyzes scientific collaboration and co-authorship networks in this university.

Method: The present study is an applied study which has been carried out using the scientometric indicators and social network analysis. The statistical population of this research consisted of all the scientific articles that at least one of the authors of referred to the Hamadan University of Medical Sciences as the affiliation and indexed in the Web of Science from 2010 to 2016. In so doing, the network analysis technique and the software on Citespace and Gephi were run to analyze and visualize co-authorship networks. Furthermore, the software on HISTCITE was used for data analysis.

Findings: All articles related to Hamadan University of Medical Sciences during the years 2012 to 2016, based on a search on the Web of Science, have 838 records. The dominant co-authorship pattern in these years is the 4 and 5 authors with 171 articles and 20.41%. The mean number of authors or collaboration index in the period considered was 5.51, the degree of Collaboration was 0.99 and the Collaborative Coefficient was 0.759. Poorolajal, Alikhani and Shahidi were the most prolific authors. Tehran University of Medical Sciences, Shahid Beheshti University and Islamic Azad University were the most prolific organizations. The greatest collaboration of Iranian researchers has been with Switzerland. Saidijam, Mahjub, Mehdizadeh, and Moghimbeigi have alloacated the highest betweenness centrality, whereas Saidijam, Mahjub, Hajilooi, and Khazaei have allocated the highest degree centrality.

Conclusion: The scientific production of Hamadan University of Medical Sciences during the period from 2012 to 2016 has grown dramatically, and collaborative research at this university is growing at an appropriate level. In this study, the degree of Collaboration and the co-operation rate are high which indicates that here is a great deal of interest in co-authorship and co-operation among researchers of Hamadan University of Medical Sciences, and it is relatively unlikely to see single-authorship, which reflects the willingness of individuals to co-authorship.
