The Analysis Of Pronoun Understanding Faced To Chapter And Its Application In Machine Design Domain Products

It is briefly introduced that the application of natural language understanding to product design, and the ways of semantic analysis and expressing of knowledge are understood. The way of understanding of Anaphora Resolution Algorithm for Double of Groups of Words and Instructions Pronoun is focused on in chapter which is a large class of pronoun in natural language understanding system. through analysis and understand of User needs which is expressed in natural language. With the whole system running, the results are conversed into the requirement of conceptual design to support the future design.First, methods of semantic analysis and expressing of knowledge are carefully introducted in paper. the characteristic of natural language understanding system is combined with ,which is based on knowledge and the ontology theory is chosen as an important complementarity to the method. Second,briefly introducted pronoun, given emphasis to study characteristic of naphora Resolution Algorithm for Double of Groups of Words and Instructions Pronoun and analyzed.After Macro-analysis is given to this class of Pronoun, establishment of static knowledge base and digestion model are gotten to.Third, based on the conceptual dependency theory and Ontology, classes templates are established and specific strategies to achieve the Anaphora Solution are given. Last, Semantic analysis of natural language understanding is applied to requirement analysis archetypal system for the design of worm. The pronoun phrase in user requirements is understood and analyzed. With other models running, the system runs well after debug.
