Knowledge management systems share information from multiple sources over the network and may have problems in maintaining the consistency due to node failures and data fragmentation in different locations. In this paper we present an architecture for a load balanced and reliable RDF storage system for semantic information distributed over a peer-to-peer network. Peers are self organized in a ring...

This paper presents the design and implementation of software tools for modeling and managing knowledge to be used in knowledge based systems or the semantic Web. The tools presented have been developed based on the inferential modeling technique, which is a technique for modeling the static and dynamic knowledge elements of a problem domain. Some major deficiencies of existing tools include the lack...
GridVine is a semantic overlay infrastructure based on a peer-to-peer (P2P) access structure. Built following the principle of data independence, it separates a logical layer - in which data, schemas, and schema mappings are managed - from a physical layer consisting of a structured P2P network supporting decentralized indexing, key load-balancing, and efficient routing. The system is decentralized,...
