A Context Awareness Non-functional Requirements Metamodel Based on Domain Ontology

Abstract

Networked software (NS) is a kind of online software produced by linking information resources on the Web with the help of intercommunication and cooperation between networks and users. Due to the complexity of NS, requirements engineering is now emerging as a critical issue in it. In the user-driven and networked-resources oriented environment, how to capture highly variable non-functional requirements become more and more important. In this paper, a context awareness non-functional requirements metamodel based on ontology is proposed, which introduces knowledge and rules provided by domain ontology to induce non-functional requirements in specified domains. So it can be used to establish meaningful semantic relationship between non-functional and context information, help users to complete their non-functional requirements to some degree, and finally support automatic detection of software requirements.
