An architecture for dynamic organization and publication in semantic portals

ABSTRACT

Semantic portals are characterized for storing and structuring informational contents according to specific domain ontologies. These contents are represented through ontological languages, which are able to infer new knowledge onto the portal. However, instantiating these portals is usually done manually or by the use of specific forms, which may be a problem, since a portal should always be up to date. In this work we propose an architecture to retrieve information from the Web according to domain ontologies, from which it is possible to integrate, structure, organize and publish information in a semantic portal, making it possible to deduce and aggregate new information to this environment in a dynamic way. This work also presents the POSEDU portal, a Semantic Educational Portal generated through the architecture proposed in this paper.
