摘要：
In peer-to-peer based information grid environment, applying ontology to describe resource has become current research trend. However, different peer maybe use different ontology to describe resource metadata according to its domain knowledge. How to discover and match these resources is a desiderate research problem in this environment. In this paper, based on formal description of node ontology and metadata model, a hybrid resource matching approach is proposed. It combines exact matching and fuzzy matching. At the same time, it combines semantic matching and resource instance feature matching. This approach will improve flexibility and accuracy of resource discovery in decentralized environment.
