It is based on the ways of semantic analysis and expressing of knowledge areunderstood, briefly introduced that the application of natural language understanding toproduct design.The way of understanding of Anaphora Resolution Algorithm forDouble of Groups of Words and Instructions Pronoun is focused on in chapter which isin natural language understanding system. Through analysis and understand of Userneeds which is expressed in natural language. With the whole system running, theresults are conversed into the requirement of conceptual design to support the futuredesign.First, method based on knowledge should be adopted in the natural languageunderstanding and methods of semantic analysis and expressing of knowledge arecarefully introducted in paper. The characteristic of natural language understandingsystem is combined with, which is based on knowledge and the ontology theory ischosen as an important complementarity to the method. Second, briefly introductedpronoun, given emphasis to study characteristic of naphora Resolution Algorithm forDouble of Groups of Words and Instructions Pronoun and analyzed.Third, based on theconceptual dependency theory and Ontology, class templates are established andspecific strategies to achieve the Anaphora Solution are given. Last, Semantic analysisof natural language understanding is applied to requirement analysis archetypal systemfor the design of worm. The pronoun phrase in user requirements is understood andanalyzed. With other models running, the system runs well after debug. |
