Mapping library and information science in China: a coauthorship network analysis
TLDR
This paper constructs the LIS coauthorship network using data from 18 core source LIS journals in China covering 6 years, and identifies some key features of this network: this network is a small-world network, and follows the scale-free character.
Analysis of the status of Iranian scientific production in some subject areas by scientometric and social network analysis indicators
The aim of this study is to analyze the status of Iranian scientific production in selected areas relating to science and information technology including information technology, management, and
Co-authorship Network Analysis of iMetrics Researchers
Introduction Nowadays, scientific collaboration is prevalent in various scientific disciplines. Scientific collaboration has been resulted from knowledge complexity, increase in demand for more
Research on Complex Network Characters of Weighted Industrial Cluster
TLDR
This paper simulated the evolution process of the industrial cluster network, and analyzed the network characteristics such as degree distribution, the average clustering coefficient and the average network shortest path.
Correlation between Impact Factor and productivity with centrality measures in journals of Information science: A social network analysis
TLDR
Examination of information science researchers’ outputs during 1996-2011 in ISI Web of Science database shows a significant correlation between Journal Impact Factor (JIF) and all centrality measures except closeness centrality at P= 0.001 and direct relationship of degree, closeness and flow betweenness and inverse relationship of betweenness.
Empirical analysis on a keyword-based semantic system
AbstractKeywords in scientific articles have found their significance in information filtering and classification. In this article, we empirically investigated statistical characteristics and
Estimating the partnership ability of Scientometrics journal authors based on WoS from 2001 to 2013 according to ϕ-index1
TLDR
This research revealed in detail that, the less scattered the co-authors of an author, the higher ϕ-index.
The use of centrality measures in scientific evaluation: A coauthorship network analysis
TLDR
It is found that the four measures are significantly correlated with citation counts and it is suggested that centrality measures can be useful indicators for impact analysis.
An improved degree measurement index based on the social network
TLDR
Based on analysis of the classic centrality metric, an improved node centrality metrics (c-index) is proposed, to measure collaboration strength of nodes in a weighted collaboration network.

The architecture of complex weighted networks.
TLDR
This work studies the scientific collaboration network and the world-wide air-transportation network, which are representative examples of social and large infrastructure systems, respectively, and defines appropriate metrics combining weighted and topological observables that enable it to characterize the complex statistical properties and heterogeneity of the actual strength of edges and vertices.
Finding and evaluating community structure in networks.

TLDR
It is demonstrated that the algorithms proposed are highly effective at discovering community structure in both computer-generated and real-world network data, and can be used to shed light on the sometimes dauntingly complex structure of networked systems.
Evolution of networks
TLDR
The recent rapid progress in the statistical physics of evolving networks is reviewed, and how growing networks self-organize into scale-free structures is discussed, and the role of the mechanism of preferential linking is investigated.

TLDR
Using computer databases of scientific papers in physics, biomedical research, and computer science, a network of collaboration between scientists in each of these disciplines is constructed, and a number of measures of centrality and connectedness in the same networks are studied.
Mutual selection model for weighted networks.
TLDR
A mutual selection model to characterize the weighted networks is proposed and can produce power-law distributions of degree, weight, and strength, as confirmed in many real networks.
Modeling the world-wide airport network
TLDR
A new model is proposed that explains the behavior of the world-wide airport network in terms of the geo-political constraints that affect the growth of the airport network and hypothesizes that in other infrastructures, critical locations might not coincide with highly-connected hubs.
