Ontology Driven Requirement Specification

Abstract—Requirement engineering (RE) process is an important step of software development lifecycle and it includes a variety of activities starting with requirement elicitation to requirement documentation. This form of engineering is the backbone of a quality product. This research focus on the attention for requirement engineers to understand the criticality of requirement specification and how a complete, consistent requirement can be extracted using an Ontology. It covers the intrinsic knowledge of the domain into machine readable easy format and requirement represented in Ontology serves as the formal representation of natural language context in a model. It is often the case in software development that requirement creep leads to an unpredictable stage in software lifecycle which becomes hard to handle. Many techniques to improved requirement specification has been tested but this paper address how user stories are represented in Ontology model by extracting the main classes of Role, Object and Action from the user and later building a model based on these core concepts along with property link for relating the three basic root classes for completion.
