Community web portals serve as portals for the information needs of particular communities on the web. We here discuss how a comprehensive and flexible strategy for building and maintaining a high-value community web portal has been conceived and implemented. The strategy includes collaborative information provisioning by the community members. It is based on an ontology as a semantic backbone for accessing information on the portal, for contributing information, as well as for developing and maintaining the portal. We have also implemented a set of ontology-based tools that have facilitated the construction of our show case - the community web portal of the knowledge acquisition community.
