As the actively implementing of Chinas sixth five-year plan for public legal education(PLE),on-line public legal education discourse(PLED)has been drawing increasing attention from the public.It,therefore,has been put at the top of the agenda by the PLE officials as to how to produce discourses that the public would accept at large in order to ensure the effect of legal education.This paper attempts to explicit the major elements behind our processing mechanism that may influence the acceptability of PLED and substantiate them into a frame so that all these parameters can be programmed for the computer to process.The aim of this research is to construct an automatic system which can evaluate multi-discourses for PLE in their acceptability.A further survey is to be conducted to verify the working of the proposed frame as well,and adaptations will be made if there is any inconsistency.This research provides PLE officials and researchers with explicit criteria when evaluating the acceptability of PLED and a corresponding automatic system which is able to structurize and evaluate massive discourses simultaneously.
