基于角色与目标注册元模型的语义互操作能力研究

为了促进需求模型间的语义互操作并有效评估角色与目标注册元模型为两种需求模型提供的语义互操作能力,提出了一种互操作能力评估方法.实验中以需求模型i＊和KAOS对会议安排进行建模得到需求模型实例,同时基于现有的角色与目标注册元模型以及对应的需求模型规格,通过连续两次映射,将需求模型的元素映射到角色与目标注册元模型的元类及其关联,并针对映射结果定量分析i＊模型与KAOS模型间部分语义互操作的程度.实验结果表明,该方法能有效评估需求模型间通过角色与目标注册元模型进行语义互操作的能力,并为需求模型间实现深度语义互操作提供度量支持.

Semantic Interoperability Based on MFI Role and Goal Registration

To improve the semantic interoperability between requirements models and evaluate effectively their semantic interoperability provided by MFI Role and Goal registration between two requirements models,we propose an approach in this paper for interoperability evaluation.Based on MFI Role and Goal registration and related specifications of requirements models,this approach maps the model elements of a requirement model to the metaclasses and the relationships defined in MFI Role and Goal registration with the i* model and KAOS model for Meeting Scheduler case.For the results of the mapping,we perform a quantitative analysis to the degree of partial semantic interoperability between i* and KAOS models,then we propose an evaluation approach for the semantic interoperability based on MFI Role and Goal registration.Experimental results show that the approach can effectively evaluate the semantic interoperability provided by MFI Role and Goal Registration between requirements models and provide measurement support to realize the deep semantic interoperability between requirements models.
