    While the number of electronic marketplaces has increased on the Internet, tools to help buyers in participating in these marketplaces (heterogeneous marketplaces) are lacking. As part of the European Union funded eBroker project on electronic marketplaces, we attempt to address this problem by developing tools that help buyers in trading in these electronic marketplaces. This paper addresses the following issues: problems buyers face when trading in heterogeneous marketplaces, sources of problems, and how to solve them.

    Due to the effects of the Internet on the global economy, organizers nowadays work, compete, and cooperate on a worldwide scale. They must be able to cope with the fast pace of worldwide competition by optimizing to market and, especially, by being highly innovative in the products and the services they offer. Because of the dynamic nature of work processes, there is a need for new frameworks and integrated computational environments to model, develop and support business processes in all their steps. We introduce a case study of an integrated system offering trade fair Web-based information services the FAIRWIS system. Our scientific and software development approaches aim at offering on-line advanced Web-based computational environments offering a common platform for the activities of all the user groups involved in the trade fair business. The underlying conceptual model integrates three basic different innovative aspects. Visual appearance: the deployment of an information visualization mechanism allows the generation of 2D and 3D representations to show retrieved data to the user in an appropriate and significant fashion. User centered approach: the employment of user models as a basis for user interface adaptation, in order to tailor information presented and functionality offered at the user interface to serve the user's needs best. Participatory design: the involvement of relevant users in charge of leading the business process definition of the organization they belong to into the development process as co-developers, not merely as consumers.

    Mobilität gewinnt zunehmend an Bedeutung in unserer Gesellschaft. Dies gilt insbesondere für die Verfügbarkeit von Informationen und Diensten auf mobilen Endgeräten. Ein neuer, stark wachsender Markt ist die Bereitstellung von Informationen und Diensten mittels der WAP Technologie, wobei aktuell meist Handys als Endgeräte eingesetzt werden. Die zumeist kleinen Displays der Endgeräte erfordern Konzepte für die Visualisierung der unterschiedlich strukturierten Inhalte und deren Interaktionen. Im Rahmen der Studie werden potentielle Inhalte und deren Interaktionen kategorisiert und Lösungsvorschläge für die Visualisierung der einzelnen Problembereiche erarbeitet.
