Requirements Specification Meta-model And Its Generation Tool

With the development of software engineering technology,the scale of software is very big,and the analysis of requirement becomes the core task of developing.The biggest question of requirement analysis is the lack of background knowledge of domain.How to obtain the system requirement is a hot spots in the software engineering.This thesis use domain ontology to describe the domain knowledge,the domain ontology as a foundation in the analysis of requirement,to eliminate software developers and users because of differences in the knowledge structure by the barrier.On the requirement analysis process,at first,proposed a ternary group as the format of requirement description.Then present a technique of the requirement classification and systematization of the seven kinds of basic association between in requirement.Based upon the aforementioned study,present a requirements specification meta-model.The meta-model play an important guide role in obtaining and analyzing functional requirement.Finally,based on the meta-model designed and implemented domain oriented software requirements specification generation tool.The tool has graphical user interface to obtain and analyze the user requirement,also realize the function of saving the requirement information as an ontology.
