Abstract

:
Scientific collaboration networks (SCNs) are web-like structures generated by
collaborating patterns between scientists. Every co-authoring activity
corresponds to a link between authors in such a network. Being successful
prototypes of evolving complex networks, SCNs display the generic properties of
self-organizing structures including social networks, in an aspect mirroring
the scientific activities of the authors also. Collecting the scientific
collaboration data of Middle East Technical University (METU) from Web of
Science, we constructed a SCN spanning the years 1980 to 2015. Performing the
network analysis procedures, we calculated the network parameters like average
separation, average degree, degree distribution, average clustering coefficient
etc. We outlined that the SCN of METU shows small-world and scale-free
properties, also having high clustering between scientists.

Keywords

Complex networks, scientific collaboration networks, scale-free networks, small-world
