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...
At present, most scholars know the important of requirements evolution, however, efficient methods to guide are still lacked. The paper presents the modeling of reflection requirement based on the ??-calculus to capture the requirements evolution, and makes it carry out efficiently and controllable. Aimed at the evolution issues of OWL-S requirements specification, this paper proposes a ??-Calculus...
The classic requirement engineering provides limited technology and inefficient methods for requirements evolution, which leads to great restriction on finish the task of requirements evolution with high-efficiency and high-quality. For resolving above problem, this paper presents a reflective requirements specification for requirements evolution. The reflective requirements specification divides...
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,...
The process of traditional requirements acquisition and analysis is generally completed by domain experts and requirements analysts, which will greatly restrict the requirements modeling automatization degree and userpsilas participation degree in the requirements process. This paper presents a reflective mechanism for evolution of requirements specifications (RMERS) that supports OWL-S. In the phase...
The traditional Architectural Description Languages ADLs lack the ability to describe the crosscutting concerns and crosscutting interactions in the software architecture, which result in the design of the system difficulty in comprehension, evolution and reuse. This paper proposes a new Aspect-Oriented ADL-AC2-ADL to provide a formal basis for representation of the tangling and scattering concerns...
Software architecture design is an important stage in the whole software development lifecycle. Yet non-functional requirements (NFRs) have been afflicted architects for a long time and how to efficiently design and address them also becomes a big headache problem. This paper focuses on the NFRs in architecture and offers a preliminary insight on separating them in a multiple dimensional way. Consequently,...
In this paper we present a semantic programming language (SPL)-a language that facilitates the integration and orchestration of semantic Web services using a process based approach. The SPL is equipped with semantic service to decouple the static binding relation between business process and its participants and it enables describing process activity implementations semantically which increases the...
