Software system have been faced challenge such as change of business rules, software resources and system context environment, software requirements must support sustainable evolution. We presented a logical model for reasoning about requirements evolution in the construction of software systems. Our model defined the π-Calculus semantics of OWL-S, giving the formal description methods for requirements...
Semantic Web Service technology provides a strong support for automation software development based on Web service. By analyzing the existing description models and methods of semantic Web service, a Semantic Web Service Description Model (WSDM4S) and its formal description based on SHOIN+(D) are proposed, which attempt to offer an effective model for description, publication, discovery, composition,...
Software architecture design is an important stage in the whole software development lifecycle.
