Self-Adapting Web-based Systems: Towards Universal Accessibility

This paper discusses the employment of self-adaptation techniques in WWW-based interactive systems, as a tool for ensuring their universal accessibility. The paper first elaborates on the underpinnings of universal accessibility and their relevance to Web applications and services. Then it provides a contextual definition of self-adapting systems and an account of how self-adaptation relates to accessibility. Subsequently, different adaptation approaches that may be employed on the Web are presented, as well as their potential correlation to accessibility solutions. Finally, the application of some of the proposed approaches in the development of Web-based information systems is presented.
