An infrastructure for scalable, reliable semantic portals

This article extends and implements the basic conceptual framework SEAL (semantic portal) with the aim of using semantic technologies in real-world scenarios through a reliable, scalable infrastructure. We also show how multiple semantic portals can interact with one another to exchange knowledge, thus fostering reuse. The building blocks of our extension include knowledge integration, processing, representation, organization, and access. The authors harness the access facilities of semantic Web technologies to provide an infrastructure suitable for industrial applications.
