Web Engineering

This volume contains the proceedings of the seventh International Conference on Web Engineering (ICWE2007), which was held in Como (Italy) in July 2007. The conference is the ?agship event of the community, promoting research and scienti?c progress in the Web engineering ?eld. The importance of the Web and of its many related technologies is widening the scope of the conference year after year, and is also leading to the cross-fertilization of several related disciplines (e.g., requirements engineering, testing and analysis, communication science, HCI, multimedia, and more).The conference brings together practiti- ers, scientists, and researchers committed to investigating and innovating the technologies, methodologies, tools, processes, and techniques used to construct, verify, and maintain Web-based applications and services. This year, the Call for Papers attracted a high number of submissions with a verygoodcoverageof allthe di?erentfacets of the Web engineeringdiscipline.A totalof172submissions(asforresearchpapers)allowedusto buildanattractive program of high technical and scienti?c quality. The 39 selected submissions comprise 26 full papers and 13 short papers (with an acceptance rate close to 23%); they cover the di?erent aspects highlighted in the Call for Papers and represent well the many Web engineering research groups active worldwide. The program spans from service-based systems to testing and analysis, from quality and metrics to models, and from semantic issues and Web 2.0 to application development techniques.
