Abstract:The co-authorship network of scientists represents a prototype of social networks. By mapping the graph containing all relevant publications of members in an international collaboration network: COLLNET, we infer the structural mechanisms that govern the topology of this social system. Structure of the network effect not only individual's collaboration pattern deeply, but knowledge flowing process profoundly. However, a single view is not enough to grasp the characters of the network in details. We have to eit… Show more
“…Commonly used measures are diameter, mean distance, components, clusters, etc. Micro-level metrics relate to the analysis of the individual properties of network actors, for example, actor position, actor status, and distance to others, which informs us about ''the differential constraints and opportunities facing individual actors which shape their social behavior'' (Yin et al 2006(Yin et al , p. 1600. It zooms in to capture the features of the individual nodes/actors in a network with the consideration of the topology of the network.…”

“…Newman studied and compared the coauthorship graph of arXiv, Medline, SPIRES, and NCSTRL (Newman 2001a, b) and found a number of network differences between experimental and theoretical disciplines. By mapping the graph containing all relevant publications of members in an international collaboration network COLLNET, Yin et al (2006) found that this scientific community displays many aspects of a small-world network and is vulnerable to disruption. Using the Science Citation Index (SCI) data for 1990 and 2000, Wagner and Leydesdorff (2003) found that in the 10 years between 1990 and 2000, the global network has expanded to include more nations and it has become more interconnected.…”
This paper aims to identify the collaboration pattern and network structure of the coauthorship network of library and information science (LIS) in China. Using data from 18 core source LIS journals in China covering 6 years, we construct the LIS coauthorship network. We analyze the network from both macro and micro perspectives and identify some key features of this network: this network is a small-world network, and follows the scale-free character. In the micro-level, we calculate each author's centrality values and compare them with citation counts. We find that centrality rankings are highly correlated with citation rankings. We also discuss the limitation of current centrality measures for coauthorship network analysis.

“…Newman studied a variety of properties of his networks, including scientists' degree and betweenness [NEWMAN, 2001A,B]. Some studies have directly applied the degree, closeness and betweenness to co-authorship networks of different domains [YIN & AL., 2006;HOU & AL., 2008]. In addition to authors' degree, closeness, betweenness and PageRank centrality, the AuthorRank centrality of authors in the domain of digital libraries was proposed [LIU & AL., 2005].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
