title = "Toward a contextual quality of service evaluation approach",
abstract = "The Quality of Service (QoS) evaluation techniques are required because web services having same functional properties are not a guarantee to have the same quality. This paper deals with a new QoS evaluation method for web services. The objective of the proposed approach is to offer the use of the existing QoS evaluation/assessment methods in constructing a new contextual QoS evaluation approach. The proposed approach is a multi-layer technique specified with the MAP formalism. The principle of the proposed contextual-oriented modelling approach is to guide the evaluator during all web services evaluation steps using different methodologies at varied levels of abstractions. A better understanding of the major web services quality factors that affect QoS will help QoS evaluators to judge the most appropriate QoS evaluation approach corresponding to their user and business requirements with more flexibility in personalising the QoS evaluation process.",
