For analysis of the posting behaviour of the programmers, the short name that each programmer uses for checkins had to be matched to the full name or email address used for postings. For 175 persons, this has been possible using several regular expressions with human check-up."}, month = {01/2002}, pages = {27 - 42}, abstract = {This paper presents results from research into open source projects from a software engineering perspective. The research methodology employed relies on public data retrieved from the CVS repository of the GNOME project and relevant discussion groups. This methodology is described, and results concerning the special characteristics of open source software development are given. These data are used for a first approach to estimating the total effort to be expended.}, keywords = {cvs, discussion, effort estimation, gnome}, issn = {1365-2575}, doi = {10.1046/j.1365-2575.2002.00110.x}, author = {Koch, Stefan and Schneider, Georg} }
