“…In their works, Chung et al [34] proposed a pattern oriented ways to deal with NFRs, and discuss the logic models as open world and close world assumptions (OWA and CWA) to evaluate or reason NFRs when using SIG as modelling language [35]. Aiming at reasoning on NFRs automatically, Wei et al [36, 37] proposed the rΣ method to fully formalise SIG with their tool supports. The work presented by Zhu et al [38] extends SIG with quantitative property to evaluation satisfice of softgoals, by introducing fuzzy linguistic variables.…”

Non-functional requirements (NFRs) address important issues in software systems, and are vital in successful software. The NFR problems in a system reflect the complexity of that system. Ideally, NFRs are systematically investigated to determine the aspects that may be harmonious or cause conflicts so that conflicts should be detected as early as possible. The work aims to extend the scopes of the NFRs framework and softgoal interdependency graph (SIG) for modelling and analysing NFRs. A formal ontological approach to modelling NFR interactions is proposed, and a core NFR ontology is developed in the ontology web language. The mechanisms involved in NFR interactions with SIG models (through interdependencies in the softgoals) are investigated and formalised. The NFRs are first analyses using a semantic modelling process to provide evaluation criteria. Next, correlation rules for implicit softgoal interdependencies are proposed from knowledge of the domain, and rules for indirect semantic correlations are proposed by extending the delta evaluation method. Reasonable rules in the semantic web environment are defined to allow conflicts between NFRs in SIG instance models to be detected and analysed. A concepts proof is performed to illustrate tool support of the proposed method, and validate the rules for conflict detection.

“…Users consistently assign significant importance to the quality of a web service. Quality of Service (QoS) is a concept that describes the non-functional aspects of a web service, and has commonly been used in research in the area [1][2][3][4][5][6][7][8]. In general, the quality of a web service may include a large number of non-functional attributes, such as cost, reputation, and availability [5].…”

Since web services intended for the same application environment tend to be functionally homogeneous, researchers have turned to their non-functional aspects in order to constructively compare web services and choose an appropriate one. In general, quality of service is very important to users. Many schemes that consider quality assessment have been proposed for web service selection. With the increasing number of qualityrelated attributes, an effective quality assessment method needs satisfactory scalability. Schemes based on the analytic hierarchy process (AHP) meet this requirement. However, prevalent methods in this vein overlook the fact that the traditional AHP needs a complete judgment matrix. In practice, all the information needed to construct a judgment matrix is often unavailable for a variety of reasons, due to which certain judgments cannot be made. In this paper, for an incomplete judgment matrix, we propose an improved AHP approach to consistency verification and the subsequent ordering. Our method can deal with situations where information is insufficient, and inherits all the merits of the traditional AHP approach. A case study establishes the effectiveness of our proposed method.
