【摘要】 CAD系统的智能化发展指出了自然语言作为人机交互的必然趋势。将人工智能技术特别是自然语言理解技术引入CAD系统,使其具有专家的经验和知识,具有学习、推理、联想和判断的能力,以及智能化的视觉、听觉、语言的处理能力,从而达到设计自动化的目的。本课题利用汉语自然语言理解技术,针对现有几种语义分析方法,特别是概念从属理论和格语法,进行了科学探究,提出了新的语义分析概念——完整语义。并将以此为基础,对汉语中包含“V的”结构复杂句的分类和处理进行了较为深入的讨论。最后,对机械设计中以自然语言形式表达的用户需求进行理解和分析,并将分析结果转化成概念设计要求或设计参数,为后续设计提供支持,为用户和设计人员提供了一个良好的设计环境。更多还原

【Abstract】 The CAD system intellectualized development had pointed out the natural language takes the man-machine interactive inevitable trend. Lead CAD system into Artificial Intelligence technology especially Nature Language Understanding technology, enable it to have expert’s experience and the knowledge, has the study, the reasoning, the association and the judgment ability, as well as intellectualized vision, sense of hearing, language handling ability, thus the purpose to achieve design automation. This topic used Chinese Natural Language Understanding technology, in view of several semantic analysis method, specially Conceptual Dependency Theory and Case Grammar, carried on the scientifically study, proposed the new semantic analysis concept - comprehensive semantics. And based on this, had carried on a more thorough discussion to Chinese Structure‘V+de’complex sentence classification and processing. Finally, carried on the understanding and analyzing to the user’s needs that are expressed in the form of natural language, and transformed analysis result into the designing requirement of the concept or design parameter, offered a good design environment to user and designer.更多还原
