Hadjila Fethallah, Chikh Mohammed Amine, Merzoug Mohammed . Optimizing Semantic Web Service Composition by using Boid Particle Optimization. International Journal of Applied Information Systems. 3, 6 ( July 2012), 10-15. DOI=10.5120/ijais12-450545
The Quality of Service (QoS) is a key factor in Web service selection and composition. In this paper, we propose a meta-heuristic based on renolds'Boid model, in order to compose a sequence of services that optimizes the QOS attributes, and conserve the semantic interaction between components in addition to the global constraints required by the user. This approach uses multiple moving operators such as the cohesion, the alignment, the random velocity, and the social exchange of positions. This paper provides also an experimentation that evaluates the optimality rates of the approach.
