HELIOS

HELIOS (Helios Evolving Interaction-based Ontology knowledge Sharing) is conceived for supporting dynamic ontology-based knowledge sharing and evolution in P2P systems.
The knowledge sharing and evolution processes in HELIOS are based on peer ontologies, describing the knowledge of each peer (that is, the knowledge a peer brings to the network and the knowledge the peer has of network), and on interactions among peers, allowing information search and knowledge acquisition/extension, according to pre-defined query models and dynamic ontology matching techniques.
