Traditional development techniques had to be adapted to thisnewsituation,andatthesametimenewtechniquesemerged.Manyresearch teams began to investigate different ways to adapt classic – but still effective – software engineering design and development techniques to the Web and Web engineering emerged as a new research field that relates several subject areas, including agents, e-commerce, e-learning, human-computer interaction, mobile technologies, security, quality and testing, the Semantic Web, etc. The International Conference on Web Engineering (ICWE) continued the traditionofearlierconferenceswiththeaimofbringingtogetherresearchersand practitioners in these areas, trying to offer a good environment where people with different backgrounds could exchange their insights in this area. Thesuccessofthisconferencegeneratedanincredibleamountofworkforthe ProgramCommitteemembersandtheExternalReviewers,leadbytheProgram Committee chairs Oscar Pastor L´opez, Luis Olsina Santos and Mart´ın Gonza´lez Rodr´ıguez. We are immensely grateful for the effort they put into the process of selectingtheverybestpapers.Therewere190paperssubmitted,with25papers accepted (13%) as long papers. A large number of papers describing ongoing researchwereincludedasshortpapersorposters.Unfortunately,wewereforced to reject many good papers. Paper selection is always a difficult task. We want to thank all the members of the Object-Oriented Technologies La- boratoryoftheUniversityofOviedo(http://www.ootlab.uniovi.es)fortheir daily support and encouragement for this enterprise. The School of Computer ScienceEngineeringofOviedogaveitsfullsupporttotheconferenceandwewant totakethisopportunitytocongratulateitonits20thanniversarycelebration.In fact, this conference was part of that celebration. We also want to acknowledge the Department of Software Engineering research group at the Pontifical Uni- versity of Salamanca, Madrid Campus, for its support in the organization and other practical matters. Thanks also to the Department of Computer Science of theUniversityofOviedo.WearealsoverygratefultoStevenFurnellandDieter Fensel for agreeing to deliver keynote lectures at the conference.
