Ontology-Based Reasoning in Requirements Elicitation

This paper introduces an ontology-based reasoning method for requirements elicitation. We start with an ontology structure contains knowledge of functional requirements and relations among them. We then propose a framework to elicit requirements using ontology: First we map initial requirements to functions in domain ontology. After that, we use rules and relations among functions to reason for errors and potential requirements. Using that result, analysts can generate questions to customers and correctly and efficiently revise requirements. We have been developing an ontology-based checking tool for requirements elicitation based on our method.
