Program Committee

Call for papers

The goal of BENEVOL is to bring together researchers who are working in the field of software evolution and maintenance. BENEVOL offers an informal forum to meet and to discuss new ideas, important problems and obtained research results.

BENEVOL accepts submissions in two categories:

Technical papers (max 4 pages main text + 1 page of references) will undergo a mild yet constructive review. We explicitly solicit papers in the early stages of research, which are still rather rough around the edges and would benefit from feedback from the community. Technical papers will be reviewed by at least three members of the program committee, assessing whether they are within the scope of BENEVOL (i.e., software maintenance and evolution) and meet its quality criteria. Authors will be asked to improve their paper and submit a camera ready version that will be published in the workshop proceedings.

Presentation abstracts (max 1 page) report on research results that have already been published, or that are ready to be submitted to a conference or a journal. They will only be reviewed for relevance, and will not be included in the BENEVOL proceedings. When accepted, the 1-pagers will be made available on the website of the workshop. Of particular interest are summaries that try to provoke discussion, initiate challenging new avenues, etc.

Submission Guidelines

All submission must conform to the IEEE Formatting Guidelines For Conference Proceedings. All submissions must be in PDF format; must use the A4 page size and must add page-numbers at the bottom. Technical papers, when properly formatted, must not exceed four (4) pages main text + one (1) page of references, while presentation abstracts should not exceed one (1) page. This limit includes the main text, figures, tables, and appendices.

Submit your paper via EasyChair. Mark the category it belongs to, i.e., a technical paper or a presentation abstract. You can upload incremental versions of your paper so do not wait until the last minute to submit.
