Rationale and aims

Modern Web applications are complex distributed systems that use the Web as their interaction means and the Internet as their communication infrastructure. Web applications allow users to navigate to retrieve information they need and use a wide variety of services that are now fundamental for an increasing number of business processes.

The interaction of hypertextual information repositories and business models is turning Web applications into unique information systems where the navigational aspects demand usability, user-friendliness, and robustness, while the application logic requires correctness and reliability. In general, a number of different qualities need to be taken into account. What makes Web quality (WQ) unique is the mix of aspects of Web applications, coming from the two different domains, namely hypermedia applications and distributed systems, and the fact that Web applications may be used by classes of users that are not easy to identify clearly beforehand. Thus, it is necessary to carefully study, define, combine, and use the many quality dimensions that characterize Web applications and their indicators. In addition, it is necessary to study the influence of these quality dimensions on specific attributes of the Web application development processes such as development effort and time, which have a fundamental impact on the economically successful building of Web applications.

The goal of the International Workshop on Web Quality (WQ 2004) is to provide a forum to discuss the various aspects of Web quality and the deployment of quality applications and services. In addition, WQ 2004 will address the study of the quality models underlying the fundamental approaches, and the investigation of the relationships between the qualities of the Web products and those of the Web processes.

The workshop is an opportunity for the communities that work on the assessment and improvement of the quality of Web applications to meet and share their knowledge to set appropriate theoretical foundations, define special-purpose methodologies, and develop supporting technology. The workshop also aims at promoting research directions on Web quality engineering by providing a forum where academic and industrial researchers can share and disseminate ideas.

The workshop aims at hosting significant, high-quality contributions in all topics related to Web quality engineering, with the goal of letting participants gain insights into the current state of the art and future challenges, create synergies through integration, and foster cross-cooperation.
