Nounal Polysemous Words Discriminance In NLU And Application In Intelligent Instruments

The application of NLU technology in the process of products design is one of the most important and difficult application of A.I.technology. This paper studies the nounal polysemous words discriminance in NLU and applies it in the design of artificial intelligence instrument. Through analyzing and understanding the clients'requirements.I transform the results into the design requirements and obtain good effects.A lot of relevant documentations are reviewed and then the main elements of nounal polysemous words discriminance and difficulties are determined. After introducing several theories and methods of NLU knowledge expression and their advantages and disadvantages,a new knowledge representation method is given, which bases on concept dependency theory and uses the framework structure as its forms and reflects the relationship between the nounal polysemous words.Then from the position of nounal polysemous words discriminance.I build the broad model of mark of language situation. Establish the model from syntacttical functions and collocation in semantic meaning and nounal syntaxes.Last I applies the nounal polysemous words discriminance the design of artificial intelligence instrument and obtain good effects.
