Cumulative Revision Map
This addresses the challenge of visualizing collaborative revision processes in documents, though it appears incremental as it builds on existing visualization methods for version control.
The authors tackled the problem of visualizing version-controlled documents, such as code, papers, and Wikipedia articles, by proposing a new technique that reveals authoring patterns, which are useful for readers, participants, and supervisors.
Unlike static documents, version-controlled documents are edited by one or more authors over a certain period of time. Examples include large scale computer code, papers authored by a team of scientists, and online discussion boards. Such collaborative revision process makes traditional document modeling and visualization techniques inappropriate. In this paper we propose a new visualization technique for version-controlled documents that reveals interesting authoring patterns in papers, computer code and Wikipedia articles. The revealed authoring patterns are useful for the readers, participants in the authoring process, and supervisors.
