A framework and ontology for dynamic Web services selection

TLDR

Current Web services standards lack a way to express nonfunctional attributes such as quality of service, which can be objective (reliability, availability, response time) or subjective (user experience) and are essential for dynamic service selection. The study proposes an agent framework linked to a QoS ontology to enable dynamic selection of Web services. The framework uses an agent-based approach where participants collaborate to assess each other's service quality and trustworthiness through the QoS ontology.

Abstract

Current Web services standards lack the means for expressing a service's nonfunctional attributes - namely, its quality of service. QoS can be objective (encompassing reliability, availability, and request-to-response time) or subjective (focusing on user experience). QoS attributes are key to dynamically selecting the services that best meet user needs. This article addresses dynamic service selection via an agent framework coupled with a QoS ontology. With this approach, participants can collaborate to determine each other's service quality and trustworthiness.
