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.
