Since it started in 1983, the International Conference on Software Maintenance (ICSM) has grown into the leading research conference on software maintenance and evolution. Every year, it provides a widely recognized international forum for software maintenance researchers and practitioners to examine key issues facing the software maintenance community.
ICSM '07 was held in the beautiful city of Paris, France, on 2-5 October 2007. The conference hosted several colocated events, including the Seventh IEEE International Workshop on Source Code Analysis and Manipulation (SCAM), the Ninth IEEE International Symposium on Web Site Evolution (WSE), the Third IEEE Workshop on Software Evolvability (SE), and the ERCIM Software Evolution (Evol) Workshop. For ICSM '07, 214 research papers were submitted, out of which the program committee selected 46 full papers for inclusion in the proceedings. The program also included keynote addresses from two distinguished speakers: Gail Murphy and Paola Traverso.
This special section of the IEEE Transactions on Software Engineering ( TSE) contains papers based on two of the best papers of ICSM '07. These papers were accepted from a set of seven papers we invited for this special section based on selections made by the ICSM Program Committee from the papers presented at the conference. The invited papers, extended and enhanced from their conference version, went through the rigorous TSE review process, overseen by us as guest editors.
The first paper, "Recomputing Coverage Information to Assist Regression Testing" by Pavan Kumar Chittimalli and Mary Jean Harrold, addresses a very important topic in the field of software maintenance, namely that of regression testing. The authors present an algorithm for recomputing updated coverage data for a changed program version with respect to a set of test cases without rerunning any test cases that do not execute the change. The algorithm is accurate as it gives the same results as would be obtained by rerunning the entire test suite.
The second paper, "How Software Developers Use Tagging to Support Reminding and Refinding" by Margaret-Anne Storey, Jody Ryall, Janice Singer, Del Myers, Li-Te Cheng, and Michael Muller, reports on two empirical studies that investigated how professional programmers and open source developers used tags to support their exploration and navigation of the source code. The studies are focused on the adoption of TagSEA, Tags for Software Engineering Activities, a tool that combines the notion of way pointing—a mechanism for marking locations in spatial navigation—with social tagging, to support programmers in defining semantic annotations to source code.
This special section is the result of tremendous effort from many volunteers in our community. First of all, we would like to thank Françoise Balmas, the General Chair of ICSM '07, for the excellent organization of the conference. The members of the ICSM '07 Program Committee helped to form the conference program through their efforts in reviewing the submitted papers and selecting the invited papers for this special section. Many thanks to all of the authors and to the reviewers for their hard work. We appreciate the excellent support and the cooperation of Joyce Arnold, TSE Publications Coordinator, during the whole process of preparing this special section.
