Numerous papers have lobbied for one or another variety of representation, other papers have argued for various properties a representation should have, while still others have focused on properties that are important to the notion of representation in general. In this paper we go back to basics to...Fri Jul 06 10:33:42 CEST 2007Santa Fe Institute, 1399 Hyde Park Road, Santa Fe, NM 87501, USA. girvan@santafe.eduProc Natl Acad Sci U S AJune127821--7826Community structure in social and biological networks.992002social-networks A number of recent studies have focused on the statistical properties of networked systems such as social networks and the Worldwide Web. Researchers have concentrated particularly on a few properties that seem to be common to many networks: the small-world property, power-law degree distributions, and network transitivity. In this article, we highlight another property that is found in many networks, the property of community structure, in which network nodes are joined together in tightly knit groups, between which there are only looser connections. We propose a method for detecting such communities, built around the idea of using centrality indices to find community boundaries. We test our method on computer-generated and real-world graphs whose community structure is already known and find that the method detects this known structure with high sensitivity and reliability. We also apply the method to two networks whose community structure is not well known--a collaboration network and a food web--and find that it detects significant and informative community divisions in both cases.Fri Jul 06 10:33:42 CEST 2007NatureDecember7070900--901Internet encyclopaedias go head to head4382005collaborative-communities Fri Jul 06 10:33:42 CEST 2007{LSCs: Breathing Life into Message Sequence Charts}1999no-tag Fri Jul 06 10:33:42 CEST 2007Logic and Software Engineering, Int.
