Research on Information System Requirment Elicitation Method Based on Ontologies

The key problem of information system development is how to acquire requirement. It has become the puzzled problem to the system developers for a long time. How to build a communication bridge between the developers and users has become a hot issue in requirement engineering. Ontology defines the common concepts and the relationships among them. A communication bridge can be built between the domain users and the system developers. Therefore, the ontology can direct the users and the developers to construct the requirement model. According to the different views of the system, their paper provides ontologies named business ontology, technique ontology and functionality Ontology for requirement elicitation. Firstly, this paper defines the concept of the ontology. Second, we describe the three ontologies in detail. Finally, through the ontologies, this paper provides the domain requirement model.
