Abstract�� To solve the problem about the lack of the semantic description and discovery for the simulation model resources in the grid resource management middleware, the ontology technology was introduced and the description ontology was defined to implement the semantic description for simulation models. The semantic matching algorithm based on the ontology inference was presented. This algorithm maps the semantic matching degree to the continuous value in . Especially, this algorithm supports inputs/outputs composition-based matching of simulation model resources. The research result was applied to the implementation of the simulation model discovery service for simulation grid, and has achieved well validation in the typical application cases.
Keywords�� simulation grid   semantic description   service matching   ontology   matching algorithm
