Research and Implementation of an NLU System

How to automatically transform plane geometry proposition of describing in natural language into specific language which are used by Computer Tutorship Expert System is a blank in Natural Language Understanding(NLU) . By researching into terrain natural language in the range of plane geometry, this paper put forward a NLU’s system which was constituted on the basis of Knowledge-bases with accidence and syntax analysis as assistant means. The system applied mostly semantic analysis’s method to realize terrain natural language’s understanding. Then a feasible language understanding system was set up to realize the transform from terrain natural language to terrain specific forms.
