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...
Complex service-oriented enterprise application needs compose Web services to satisfy user specific requirements. Several approaches have been proposed to fulfill this need. However, those approaches and their runtime infrastructure are weak in providing flexible features such as dynamism and adaptability, which are needed in mobile networks and wireless scenarios. A semantic programming language...
Reusing software architecture, which is a kind of coarse-grained software resources at design time, is always a very difficult problem in the realm of software engineer. We consider that there are two fundamental reasons for this problem: one is the lack of information which supports the process of reusing software architecture; another is the lack of effective reusing approach. So this paper proposes...
