Analysis Of Interrogative Pronouns In NLU And Its Application In Product Design

Product Requirement Analysis has become an inevitable trend. In this paper, the interrogative pronouns processing technology of Nautral Language Understanding is applied in Product Requirement Analysis. Firstly, the development status and difficulties of NLU is introduced. Then we talk about the basic theories of interrogative pronouns study, including three analysis methods of Natural Language Understanding and the common knowledge representation methods, as well as the basic concepts and the semantic types of interrogative pronouns. With the analysis of usages of interrogative pronouns in texts, the processing content has been determined. According to the ontologic relationship of concepts and features of concepts set, by using the tree model of Conceptual Dependency Theory, we work out the processing strategy of interrogative pronouns in texts. Afterwards, to improve the processing efficiency, by the analysis of different semantic interrogative pronouns, the usages of interrogative pronouns are classified from the structure and sematic aspects. And for each type, the theoretical model is designed. Moreover, by designing related knowledge representation and writing the rules, interrogative pronouns processing is realized. Finally, the processing model is applied in the NLU system for Product Design, and interrogative pronouns understanding in the customer requirements of product in Chinese is realized.
