Abstract
At the stage of current studies, the synergetic-linguistic model is mainly used for the validation of individual languages, lacking application to the measurement of linguistic differences. In addition, the structure of the model is largely fixed and the pattern is relatively simple. We have innovatively proposed a lexical differences analysis framework and conducted a comparative study between Vietnamese Chinese (VC) and Mandarin Chinese. The framework, based on the synergetic-linguistic model, shows great effectiveness of lexical synergetic system modification and the reasonability of determining the similarity threshold. The comparative results demonstrate distinct differences that lay between VC and Mandarin Chinese through difference measurement.
