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

Orchestrating SOA Using Requirement Specifications and Domain Ontologies

“…Cross-Domain Ontology Mapping: Ajmeri et al [7] propose an approach to identify the concepts that link different ontologies using semantic similarity mapping. The semantic similarity between concepts is calculated based on Fig.…”

“…The semantically similar concepts identified using the above approach are the concepts which map two different domain ontologies (cf. [7] for a detailed description of the cross-domain ontology mapping algorithm).…”

“…Identification of Candidate Services: Once the domain ontologies are linked using the semantic similarity mapping approach, we identify if the concepts in the ontology that are associated with the user query are services. We use the following criteria in [7] to identify if the concept represents a service: the concept or its equivalent concept in the ontologies must be present in the user stories, and the concept or its substring should be part of a verb phrase (VP). However, if it is part of a noun phrase (NP), it should be prefixed by a VP.…”

“…Since a service composition may involve services from different domains, one of the main challenges of our approach is to link domain ontologies to handle requirements from multiple domains. To address this challenge, we extended the existing approach by Ajmeri et al [7] that helps requirement analysts visualize how requirements span across multiple domains. The ontologies are linked using the semantic similarity of concepts.…”
