A system for monitoring, assessing and certifying Quality of Service in telematic services

This work presents a knowledge-based system and architecture for the formalization of quality of service (QoS) characteristics and measurement methods in telematic services, and for the collection, distribution and assessment of the QoS information obtained using these methods. The solution makes use of ontologies and reasoning technology to define and compare QoS information. The system can help customers to select the service offer that best fits their quality requirements. Providers will use it to detect when the delivered service fails to fulfill the quality agreements that they signed with customers.
