基于对象过程方法的概念建模语言研究

Concept modeling language research based on the object-process methodology

对象过程语言简洁而严谨,但在建模时某些概念难以被准确、细致地表达.针对此问题,通过本体论和经验主义认识论相结合的思维方式识别缺失的语义和易混淆的语义,改进相关语义,并优化语法.对对象过程语言扩展的语义主要包括:1)增加“观测”过程构造型和“描述链接”关系,区分物理事物和信息事物这两种语义;2)增加“关联算子”过程构造型,使对象过程语言能描述多种参数之间的数值关系、逻辑关系或映射等关系;3)限定“影响链接”的方向,有效区分过程与对象之间的两种影响关系.对象过程语言是图文等价的,这为验证工作提供了有效方法.利用典型模型的文本模式验证改进方案.改进方案能使概念模型的内容更准确、更细致.

Object-process language(OPL)is concise and rigorous,but some concepts are difficult to be expressed accurately and meticulously in modeling.In view of this problem,the thinking mode combining ontology and empiricism epistemology is applied to identifing the missing semantics and confusable semantics,improving the relevant semantics,and optimizing the grammar.The extended semantics of OPL mainly includes:1)adding“observation”process stereotypes and“description link”to distinguish the two semantics of physical things and informatical things;2)adding“association operator”process stereotypes to enable OPL to describe the numerical,logical,mapping and other relationships between various parameters;3)defining the direction of“impact link”and effectively distinguishing two relationships between process and object.OPL is graph-literal equivalent,which provides an effective method for verification.Verifying the improved scheme by using typical models of text patterns,the improved scheme is proved to be able to make the content of conceptual model more accurate and detailed.
