Bellefield Ave., Pittsburgh, PA 15260 (United States) Abstract Three group centrality measures--degree, closeness, and betweenness--are utilized in this paper to explore the role of disciplines in two journal co-citation networks by using 677 journals from 40 disciplines categorized by Web of Knowledge. The result shows that social science disciplines play a more central role in knowledge communication and… 

Figures and Tables from this paper

Linking the network centrality measures closeness and degree

The authors derive a mathematical approximation that link two of the most used centrality measures in graph theory, degree and closeness, finding that the inverse of closeness is linearly dependent on the logarithm of degree.

k-step betweenness centrality

This work proposes an algorithm that can compute successively the k-step GBC of several groups of vertices, a measure of the likelihood that at least one group member will get the information communicated between pairs of Vertices through shortest paths within the first k steps of the start of the communication.

EDGly: detection of influential nodes using game theory

This novel proposed algorithm aims to find the most significant communities in a graph with community structure and then employs the SV-based games to finding the most influential node from each community.

Using network centrality measures to improve national journal classification lists

The aim of this paper is to analyse the potential use of network centrality measures to identify possible mismatches of journal categories, and emphasise the use of these measures to better calibrate journal classifications as a general bias in these lists towards older journals is observed.

The Impact of intragroup Social Network Topology on Group Performance: Understanding intra-organizational Knowledge Transfer through a Social Capital Framework

This thesis examines the effects of intragroup social network relations on group performance. Building on prior studies, it views social network topology along structural, relational and cognitive

Global Rank Estimation

This work proposes fast and efficient methods to estimate the global centrality rank of a node without computing the centrality value of all nodes and discusses how to apply these methods for degree and closeness centralityRank estimation.

A methodology for structured literature network meta-analysis

This paper aims to structure extant literature data into a network and demonstrate by graph visualization and manipulation tool “Gephi” how to obtain an evidence-based literature review and enables researchers in any domain to systematically extract and visualize meaningful and evidence- based insights from existing literature.

Faster computation of successive bounds on the group betweenness centrality

The method is an improvement of the method of Kolaczyk et al.

Network Analysis of Design Automation Literature

A new unsupervised learning algorithm, propagation mergence (PM), was created to address identified shortcomings of existing methods and applied to study the existing DAC citation network, and investigated the DAC co-authorship network by identifying key authors and showing that the network structure exhibits small-world-network properties.



Mapping library and information science in China: a coauthorship network analysis

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.

Maps of science as interdisciplinary discourse: co-citation contexts and the role of analogy

This analysis reveals that interdisciplinary connections are often based on authors’ perceptions of analogous problems across scientific domains, and cue words drawn from the citation contexts suggest that these connections are viewed as important and ripe with both opportunity and risk.

Mapping the backbone of science

A new map representing the structure of all of science, based on journal articles, is presented, including both the natural and social sciences, including biochemistry, which appears as the most interdisciplinary discipline in science.

Centrality in social networks conceptual clarification

Detecting, identifying and visualizing research groups in co-authorship networks

A method for detecting, identifying and visualizing research groups and the structures of the socio-centric and co-authorship networks and the strategies underlying collaboration among researchers, were discussed with the members of the departments analyzed.

A global map of science based on the ISI subject categories

The nested maps of science (corresponding to 14 factors, 172 categories, and 6,164 journals) are brought online and an analysis of interdisciplinary relations is pursued at three levels of aggregation using the newly added ISI subject category of "Nanoscience & nanotechnology".

Using field cocitation analysis to assess reciprocal and shared impact of LIS/MIS fields

Using Field Co-citation Analysis to Assess Reciprocal and Shared Impact of LIS/MIS Fields Fields is used to assess reciprocity and shared impact in information systems research.

Social Network Analysis: Methods and Applications

This paper presents mathematical representation of social networks in the social and behavioral sciences through the lens of dyadic and triadic interaction models, which provide insights into the structure and dynamics of relationships between actors and groups.

Journal maps on the basis of Scopus data: A comparison with the Journal Citation Reports of the ISI

Using the Scopus dataset (1996–2007) a grand matrix of aggregated journal-journal citations was constructed. This matrix can be compared in terms of the network structures with the matrix contained
