%X The concept of pre-define regions and semantic circle was used,then a semantic circle caching model based on pre-define regions was proposed,which can efficiently resolve the problem of semantic relativity.A cost function based on semantic segment distance and valid scope was presented as the basis of caching replacement.The implementation and experiment results of the replacement policy named PDRSCR(Pre-Defined Regions Semantic Circle Replacement) was given in detail.
