An Ontology-based method and tool for cross-domain requirements visualization

The complexity associated with understanding the cross-domain scope of a requirement has always been a challenge. Requirement Analysts use their experience in determining the functional scope boundaries of requirements. However, chances of missing out key concepts in domains peripheral to the domain of interest are quite high. Ontologies are increasingly becoming the standard way of representing shared understanding of a domain and their use in understanding and visualizing the cross-domain scope of requirements can be a step towards improving the completeness of requirements. We present a method - based on ontology mapping technique, and an assisting tool that would help Requirement Analysts visualize - how requirements span across multiple domains.
