Abstract

Many recently emerging component-based Web portal application platforms allow end users to compose dynamic Web dialogues on the fly. Experts predict that this paradigm will enable a class of new applications for Web-based content delivery in information-rich, agile business domains, such as health care. We present a conceptual analysis of the user-based composition paradigm currently used and argue that its usability is limited with respect to complex, dynamic applications. To overcome these limitations, we present an alternative composition paradigm, which is based on a semantic model of a portal’s application domain. We evaluate this approach with an application scenario in the health care domain.
