OntoZilla: An ontology-based, semi-structured, and evolutionary peer-to-peer network for information systems and services (in Journal of Future Generation Computer Systems) (original) (raw)

We present a system called "OntoZilla", which combines ontologies and peer-to-peer (P2P) technology, with a vision of improving the information search process and facilitating greater integration as well as interoperability. In OntoZilla, peers supporting the same concept are grouped into the same cluster, and the relationships between clusters are modeled according to the concepts they specialize in. Therefore, a query belonging to a specific concept can be routed to the suitable group of peers in a systematic way, thus supporting efficient concept search. Moreover, since peer relationships are based on peers' expertises which may change over time, our semi-structured system can flexibly cope with the changing environment as peers evolve.
