Automatic service composition is an important issue in the field of grid, which enables individual services to be composed together to provide the end user a more powerful service, which would significantly improve the service reuse. This paper proposes a novel service composition approach based on QoS global optimization which tackles the QoS-aware composition optimization problem using ACO algorithm...
With the development of grid service technology, the grid service matching becomes a hot-spot. Service matching is one of the key technologies that can effectively improve the reuse of resources. After analyzing the reason of the lack of communication beforehand between the service requestors and the service providers, this paper proposes an approach to add semantic information into the service description...
Grid service matching is one of the key technologies to improve the reuse of resources and achieve high efficiency in service grid. This paper introduces more semantic features into the Grid service matching and then proposes a four-stage service matching model with semantics (FSMMS) which computes the similarity with the features of the service category, the precondition and outEffect, the inputs...
