Semantic QoS Synchronization of Web Services

Due to their promise to transform the way business is conducted, Web services increased tremendously in number. Accordingly, service providers are competing to make their services more visible to get closer to service consumers. This fact leads to having service description (including the quality of service, for short, QoS) of same Web services published in many service registries but with different vocabularies and terminologies according to the service publication requirements of each service publisher. Consequently, the challenge is how to synchronize QoS values over these service registries, whenever they are updated. The solution to this problem should be based on the semantics of QoS to be able to synchronize their values regardless of their different representations.
