Linking Quality of Service and Experience in Distributed Multimedia Systems Using PROV Semantics

Experimenters creating innovative applications that combine diverse distributed multimedia services with rich end user applications require enhanced insight into the relationships between the perceived quality of experience (QoE) and provided quality of service (QoS). We have implemented software which not only captures QoE and QoS measurements but, using a provenance ontology, also records the interactions between end users, the content, applications and the services. The data exploration interface provided allows an experimenter, working with participants in real-world situations, to understand the detail of the participants´ usage and experience of the system and the system performance factors contributing to their quality of experience.
