This paper presents a social network analysis (SNA) of the recommender system research area based on relations of co-authorship. A collaborative 10 year data set of 192published papers in the top 125 MIS journals database was analyzed. In order to identify relation of co-authorship, this study performed centrality, centralization, and key player analysis. The results represented in this paper have significant implication. First, through betweenness centralization score, we find that oligopolies of the co-author network by several recommender systems researchers are still remaining. Second, through centrality scores, we discover that Kim, J. K and Zhu, X and Gil-Solla, seem to be very popular and influential individuals. But they are closely followed by a number of other popular individuals. Finally, Our research result will provide the practitioner and academic with guideline for future research on recommender systems.
