Abstract: Studying scientific collaboration using coauthorship networks has
attracted much attention in recent years. How and in what context two
authors collaborate remain among the major questions. Previous studies,
however, have focused on either exploring the global topology of coauthorship
networks (macro perspective) or ranking the impact of individual authors (micro
perspective). Neither of them has provided information on the context of the
collaboration between two specific authors, which may potentially imply rich
socioeconomic, disciplinary, and institutional information on collaboration.
Different from the macro perspective and micro perspective, this article
proposes a novel method (meso perspective) to analyze scientific collaboration,
in which a contextual subgraph is extracted as the unit of analysis. A
contextual subgraph is defined as a small subgraph of a large-scale
coauthorship network that captures relationship and context between two
coauthors. This method is applied to the field of library and information science.
Topological properties of all the subgraphs in four time spans are investigated,
including size, average degree, clustering coefficient, and network
centralization. Results show that contextual subgprahs capture useful
contextual information on two authors' collaboration.
