There exist many portal servers that support the construction of personalizable “My” portals, that is, portals that allow the user to have one or more personal pages composed of personalizable services. The main drawback of current portal servers is its lack of generality and adaptability. This paper presents the approach we are following in the new version of MyPersonalizer, a J2EE-based frame...

We describe collaboration models in Web services, and how to achieve universal access in the heterogeneous devices including conventional desktop PCs and mobile devices. We discuss how a rich synchronous and asynchronous collaboration environment can support virtual communications built on top of Web service infrastructure based on industry standard portal technologies, such as XML, Apache proj...

The Internet is enhancing and challenging traditional approaches to teaching undergraduate neuroscience. In addition to the new FUN-supported development of a Society for Neuroscience Portal for higher education, there is a wealth of available teaching resources currently housed on the web. This article discusses the current state of digital libraries and introduces a series of exemplary web-ba...

We discuss the characteristics of portals defined as web-based interfaces to applications. In particular we focus on portals for either education or computing which we assume will be based on technologies developed for areas such as e-commerce and the large Enterprise Information Portal market. Interoperable portals should be based on interface standards, which are essentially hierarchical fram...

We analyze the development of educational (EDU) web portals from the perspective of meta-design. Here, we focus on the technical issues of meta-design only and consider design-for-change. Our contribution is a variability model based on the variability analysis, generic portal development processes, sub-processes and their relationships. We analyze the interface design problem in the context of...

Developing an intelligent e-Business portal needs various WI technologies. In order to represent, manage, integrate, share, and use the information coming from huge, distributed, multiple data sources, we present a conceptual model with dynamic multi-level workflows corresponding to a multi-layer Grid architecture for multi-aspect analysis in building an e-Business portal on the Wisdom Web, and...

The German National Library of Science and Technology (TIB) is developing an innovative AV-Portal which allows web-based access to scientific films. Therefore the TIB would like to transfer existing methods of visual search, visualisation and automatic content analysis into the field of digital libraries. In order to ensure optimum usability of the AV-Portal, the development has been accompanie...
