篇章中基于不同抽象程度的名詞聚類及其在產(chǎn)品設(shè)計(jì)領(lǐng)域中的應(yīng)用
[Abstract]:In this paper, noun clustering in natural language understanding based on different degrees of abstraction is applied to product design to understand and analyze the user's needs expressed in natural language form. The analysis results are transformed into the requirements or design parameters of product conceptual design, which provide support for subsequent design and provide a good interactive environment for users. Firstly, several knowledge representation methods in natural language understanding are introduced in detail. By comparing their advantages and disadvantages, we adopt the concept as the basic unit and the template as the basic framework. The theory of concept subordinate tree represented by tree hierarchy is used as knowledge representation method. Secondly, based on the concept models of nouns with different degrees of abstraction, the reasoning based on concept connotation and the reasoning after concept instantiation are discussed. On the basis of conceptual attribute clustering and comparative clustering, a clustering model of noun concepts in text is proposed and finally implemented. Finally, the noun concept clustering model based on different degree of abstraction is applied to the user demand analysis of intelligent instrument design, and the results are satisfactory.
