The eight workshop on Knowledge Engineering and Software Engineering (KESE8) was held at the ECAI 2012 (The European Conference on Artificial Intelligence) organized by European Coordinating Committee for Artificial Intelligence in Montpellier, France, and wants to bring together researchers and practitioners from both fields of software engineering and knowledge engineering, as well as the Semantic Web community. The workshop endeavors to promote the use of KE techniques in SE problems, where significant benefits can be derived from their use. The general goal of the workshop was to show how the KE techniques can provide practical solutions in SE issues. On the other hand, the influence of SE methods and tools on the practical design of KBS within KE.AGH University of Science and Technology, Kraków, Poland. University of Almería, Almería, Spain
