Reserch On An Method Of Requirement Analysis Drived By Ontology

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. Domain ontology is a semantic model, which describes the semantic relation of domain conception. Domain ontology can act as the foundation of domain understanding and the bridge of communication; consequently resolve the question of requirement analysis.The thesis present a technique of requirement analysis based on ontology, the technique join the ontology into the traditional process of software development. We research the develop technique of ontology used in requirement analysis, and present a capture algorithm of application ontology based on domain ontology. At last, we present the method of change the application into class diagram.The thesis is structured as follows: Chapter 1 is the introduction. In chapter 2, we introduce the develop technique of ontology used in requirement analysis, and the describing language of ontology. In chapter 3, we discuss a capture algorithm of application ontology based on domain ontology. In chapter 4, we discuss the method of change the application into class diagram. In chapter 5, we introduce the realization of prototype system. The last chapter is summarization and expectation.
