The Web service composition is one of the most effective ways to combine the current net resources and realize the re-utilization and satisfy the personalized requirements, and the foundation of the composition is the Web service selection. Expounded the basic principle of genetic algorithm, and brought the genetic algorithm in the field of Web service selection, and transferred the problem of Web...
As an intelligent algorithm with the mechanism of positive feedback, the ant colony algorithm is useful in solving the optimal problem. Web service selection is the foundation of the Web service composition which is one of the most important ways to satisfy the users' personalized requirements. Firstly, analyzed the problem of Web service selection based on expounding the basic principle of ant colony...
The Web service composition is one of the most important ways to satisfy the users' personalized requirements and supply the high quality service for users, and the foundation of service composition is the selection of Web service. Firstly, expounded the basic principle of Ant Colony Algorithm and analyzed the model of Web service selection and brought the algorithm into the fields of Web service...
Matchmaking is the basis of service discovery and composition. Using ontology semantically express the capabilities of services, accurately match, discovery and composition service. Domain ontologies and Formal Concept Analysis (FCA) aim at modeling concepts, the role of FCA in ontology engineering is supporting the critical task of reusing independently developed domain ontologies. Evaluating concept...
A novel multi-objective optimization based particle swarm optimization algorithm is presented to solve the global optimization problem for based services selecting in Web services composition technology. This algorithm takes Web services selection as a multi-objective constrained optimization problem with constraints. It introduces multi-objective PSO intelligent theory to optimize multi parameters...
Describing and verifying OWL-S with the Unified Modeling Language (UML) cannot only improve the efficiency of developing semantic Web service, but also ensure the correctness of dynamic composition process; abstractly modeling semantic Web services with model-driven architecture (MDA) at a higher level is helpful for dynamically binding services. This paper proposes an effective approach to describe...
Web services composition becomes an ideal choice for enterprise level integration. This paper focuses on the problem of how to select the existed Web services so as to compose a complex service with incomplete QoS information constrains. We first proposed a model of composite service based on Markov process, and then a novel service composition algorithm was designed and implemented, which is built...
