Based on Relevance Theory,this paper analyzes the process of interpretation thinking and interpretation research and discusses tentatively the prediction in interoperation based on relevance theory with an emphasis on dynamic contextual assumption.

The activation of a series of contextual assumptions based on cognition is the premise of the information decoding mechanism of the structure lian…dou/ye… from the viewpoint of participant/hearer,the projection of three kinds of semantic information of lian…dou/ye… on the outside world is the theoretic foundation of the information decoding,and the structure lian…dou/ye… forms a continuum.

This paper studies the dynamic relationship between parole and langue,information and communication intention,maximum and optimal relevance,and contextual assumption and new information,by applying the principle of maximum and optimal relevance with reference to context,motive,cognitive environment and other factors.

With Dynamic Context Model offered by Istvan Kecskes lately,we have a second thought on Relevance\' cognitive context theory,the context assumption,and we state and prove that "Self Association-Prediction" Model is the very thought pattern and construction mechanism of Context Assumption.

According to Relevance Theory,verbal communication is an ostensive-inferential process on the basis of certain contextual assumptions.
