Centrality literature network.

Dataset   Centrality

Description

Centrality_literature.net: 129 vertices (publications), 613 arcs (citations, pointing towards the citing paper), no edges, no loops, line values (1 - regular citation, 2 - double citation, which is possible if the citing paper or the cited paper refers to two mutual citing papers shrunk to one combined vertex).
Centrality_literature_year.clu: a partition showing the year of publication of the paper (129 vertices), which is also indicated by the last two digits in the label of a vertex.

Background

In 1979, Linton Freeman published a paper which defined several kinds of centrality. His typology has become the standard for network analysis. Freeman, however, was not the first to publish on centrality in networks. His paper is part of a discussion which dates back to the 1940s. The network shows the papers that discuss network centrality and their cross- references until 1979. Arcs represent citations; they point from the cited paper to the citing paper.
In principle, papers can only cite papers which appeared earlier, so the network is acyclic. Arcs never point back to older papers just like parents cannot be younger than their children. However, there are usually some exceptions in a citation network: papers which cite one another, e.g., papers appearing at about the same time and written by one author. We eliminated these exceptions by shrinking the papers by an author which are connected by cyclic citations. In the centrality literature network, we used the latter approach (e.g., two publications by Gilch in 1954 are shrunk to one paper #GilchSW-54).
