This research introduces semantic method into the study of the data storage and information sharing models in grid environments. We set out from application and base our research on the application of mass information sharing in large scale networks. The research utilizes the state-of-the-art technologies such as complex networks, information extraction, information retrieval and etc. to study the issues including ontology semiautomatic generation, ontology based information extraction, information classification, information representation and information querying, ontology update, merging and mapping, semantic similarity based self-organized topology of large scale networks, and efficient information search in semantic based self-organized large scale networks.

　　We have developed the SemreX system, which is a semantic based peer-to-peer system for bibliography information sharing. Semantic based Grid Storage Architecture
