AI for the Web — Ontology-based Community Web Portals

Community web portals serve as portals for the information needs of particular communities on the web. We here discuss how a comprehensive, ontology-based approach for building and maintaining a high-value community web portal has been conceived and implemented. The ontology serves as a seman-tic backbone for accessing knowledge on the portal, for con-tributing information, as well as for developing and maintain-ing the portal. In particular, the ontology allows for flexible querying and inferencing of knowledge. Actual usage of our technology is facilitated through a set of tools that are about to turn our research system into a portal for wide-spread usage right now. The development of these tools has greatly ben-efited from some first experiences we had with actual users of the community web portal of the knowledge acquisition community.
