SPEAKER: Prem Devanbu, University of California at Davis, USA

TIME: 11.00

 

ABSTRACT:

Commercial software project managers design project organizational structure carefully, mindful of available skills, division of labour, geographical boundaries, etc.  These "cathedrals" are to be contrasted with the "bazaar-like" nature of Open Source Software (OSS) Projects, which have no mandated organizational structure.  Any structure that exists is dynamic, self-organizing, latent, and not necessarily explicitly stated.  However, because of the size and complexity of some OSS projects, we expect that sub-communities will form organically within these project teams, suggesting that within the "bazaar", some sorts of small cathedrals will spontaneously emerge.  Building on advances by statistical physics researchers in detecting community structure in complex networks, we extract and evaluate latent subcommunities from within the email social network of several projects, including Apache HTTPD, Python, PostgresSQL, Perl, and Apache ANT.  We show that these a) subcommunities do exist b) theyare statistically significant c) they are more pronounced in discussions concerning artifacts than in other discussions (e.g., process, personnel etc) d) they are significantly related to collaborative technical behaviour (commits).
