Research And Implementation Of Compound Sentence With The Special Verb Of Nature Language Understanding In Product Design

Presently the auxiliary designing technique of the computer designs for products mainly aimed at later stage, the support to its early stage is not enough. So this text puts forward and gets deeply to nature language understanding the early stage of product design , For example the process of demand analysis, let nature language understanding serve as such intelligence interfaces between the systems as users and product design , through understanding what users want , thus guide the designer's work.. In order to improve the automation and intelligent of machinery design.The current situation of product design and development goal were introduced at first, The systematic necessity and feasibility of nature language understanding of the field was analysed. Secondly, carry on contrast to existing sentence structure semanteme analytical method, The concept of subordinate to the theory was selected as basic theory of this text. Moreover, classify and abstraction and the relation of the concept of subordinate were introduced, strengthen the understanding of concept and abstract problem of the classification to know. And then classified , summed up , summarized the special verb , has proposed the thought of regarding verb as the centre of analytical method and semanteme based on " incident", The semanteme treatment method of the combine with classify and decomposition was adopted, simple and compound sentence with special verb of domain Chinese were dealed with deep research. semanteme implementation process of the special verb was detailedly presented.Finally, applied nature language understanding to human-computer interaction of user's needs of mechanical transmission analysis, had set up corresponding knowledge base and the rule of some incidents, through debuged, run in sound condition, It is hopeful that realize computer auxiliary user's needs analysis.
