Overview

The KA2 ontology has been built within the Knowledge Annotation Initiative of the Knowledge Acquisition Community (KA)2

More information:

• (KA)2 aims at "intelligent" knowledge retrieval from the Web and automatic derivation of "new" knowledge. In other words, it aims at knowledge-based reasoning on the Web, as opposed to the more usual information retrieval. Another objective of the initiative concerns a distributive ontological engineering process.
• 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.
