Managing QoS Acceptability for Service Selection :: a Probabilistic Description Logics Based Approach

Quality of Service (QoS) guarantees are usually regulated in a Service Level Agreement (SLA) between provider and consumer of services. Such guarantees are often violated, it may however be the case where the available services do not match exactly all required QoS, leading the system to grind to a halt. It would be better to look for an approximation for acceptable QoS and avoid the complete stopping of the running services. This paper aims at making dynamic QoS acceptability easy for service selection. The proposed model is based on an extension of existing probabilistic description logics reacting to QoS variations. The contributions made are twofold (1) a query description language to express the required QoS by means of a probabilistic description logic (2) a reasoning algorithm for decision making about the acceptability of QoS w.r.t the probabilistic description.
