Intelligent Resource Discovery Based on Web Service in Information Security Resource Grid

Intelligent discovery model with the concept expression for information security under the information security resource grid is proposed in this thesis, in which Concept Expression is adopted in the formal method of description on information security knowledge, this method is used to support reasoning and semantically intelligent discovery. Characterization and resource optimization are two main technologies in resource intelligent discovery. Through normative concepts and semantic correlation between concepts, resource characteristics are dealt with in terms of characterization and in regard to the disunity of concepts while algorithm of resource characteristics is proposed. During the optimization process of the resource discovery, the optimized algorithm based on concept expression of reasoning is sought for realizing the automatic expansion of concepts and enhancing coverage and accuracy.
