Web Engineering

In the last decade, we have seen tremendous successes in World Wide Web and Internet technologies. Traditional development techniques had to be adapted to thisnewsituation,andatthesametimenewtechniquesemerged.Manyresearch teams began to investigate di?erent ways to adapt classic but still e?ective software engineering design and development techniques to the Web and Web engineering emerged as a new research ?eld 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 tradition of earlier conferences with the aim of bringing together researchers and practitioners in these areas, trying to o?er a good environment where people with di?erent backgrounds could exchange their insights in this area. Thesuccessofthisconferencegeneratedanincredibleamountofworkforthe Program Committee members and the External Reviewers, lead by the Program Committee chairs Oscar Pastor L opez, Luis Olsina Santos and Mart ?n Gonz alez Rodr ?guez. We are immensely grateful for the e?ort they put into the process of selecting the very best papers. There were 190 papers submitted, with 25 papers accepted (13%) as long papers. A large number of papers describing ongoing research were included as short papers or posters. Unfortunately, we were forced to reject many good papers. Paper selection is always a di?cult task.
