Abstract: Software requirements description and analysis have always been the important work of requirements engineering, while there exists close association, and automation needs analysis should be based on standard description of the requirements. This paper presents an automatic analysis modeling method based on the structural description of domain requirements, and the whole system is described according to some given organizational structure. The sentence pattern is combination of semantically rich pattern and common sentence pattern, meanwhile natural language is used to deal with related technical problem. Automatic modeling is achieved based on modeling elements identification under structural description through predefined conversion rules, and finally forms the UML graphical analysis results.

Key words: domain requirements, natural language processing, sentence rule, text analysis, requirements modeling

摘要： 软件需求描述和需求分析建模一直以来是需求工程的重要工作，且存在紧密的关联，自动化需求分析建模与验证需要以规范的需求描述为基础。提出基于领域需求的结构化描述的自动分析建模方法，通过对系统整体按照一定的组织结构进行描述，描述句式采用富含语义的句型和普通句型相结合的方式，运用自然语言处理相关技术，通过预定义的转换规则对结构化描述下的需求文本进行建模元素识别，实现自动化的建模，最终生成UML图形化分析结果。
