Scalable and Reliable Semantic Portals (SEAL) in Practice

We present a scalable and reliable framework for Semantic Portals which is an extension of our existing SEAL approach. We illustrate the instantiation of our framework by the real-world example of a heterogeneous and distributed infrastructure of Semantic Portals, viz. the portal of our institute AIFB, the OntoWeb.org portals and the KM-Vision.org portal. The approach relies on the application of current semantic technologies whereby we still keep practical usability. Generally, we show that our approach can be used to build up Semantic Portals from scratch or to build up on existing portal infrastructures as a layered Semantic Portal on top. We present several modi for integration of multiple portals and show how we address practical issues like scalability and robustness of Semantic Portals.
