An ontology for software requirements modelling

Ontology provides means to describe concepts effectively. It has become an increasingly useful tool in understanding concepts in various fields of Information Systems and Technology. The aim of this paper is to build and evaluate an ontology that standardizes concepts and semantics of requirements modelling notations, in order to provide a common understanding of those concepts among software engineers. This ontology will lead to easy learning of modelling diagram concepts for new system developers. It will also allow software engineers to move from one modelling notation to another easily.
