An Efficient User-Centric Web Service Composition Based on Harmony Particle Swarm Optimization

Abstract

Generally, the composition is the process of combining services to fulfill complex tasks based on their functional and non-functional values such as quality of services (QoS) and context attributes. However, to produce a composition with values that satisfy many requirements is a challenging focus. In this article, the authors proposed a new approach centered evolutionary algorithm called the harmony particle swarm optimization (HPSO) algorithm that leads to an efficient composition with better performance and execution time. The authors' proposed method is a new hybrid version of the harmony search and the particle swarm optimization. The HPSO is designed to generate the best web service composition in a discrete search space. Furthermore, the method includes two filtering processes called Skyline operator and local consistency reinforcement techniques. These methods filter the search space and keep only the most representative candidate services. Results show the effectiveness and the accuracy of the proposed approach.

Global Optimization Algorithm for Cloud Service Composition

“…Built on the proxy method, this technique can compose services by identifying QoS parameters, based on the fitness function, it can select the best service by using PSO [15]. An evolutionary algorithm [16], called harmony PSO, which can provide an effective composition with better performance and execution time. Hosseini Shirvani [17] proposed a bi-objective time-varying particle swarm optimisation algorithm for Web service composition.…”

Towards a Personalized Web Services Composition Approach

“…Many existing approaches in the literature treat the concept of personalization for Web service composition. In this regard, (Fekih et al) [5] [present an approach that is both semi-automatic and semantic one hand, user intervention is necessary, where it is represented from its profile and its preferences. Furthermore, the service selection is made up of a semantic description based on OWL-S [4].…”

“…The composition of services is coming precisely to answer these two questions. After analyzing several definitions (Fekih et al) [5], (Shanchen et al) [6], (Yuan et al) [7], we hold two views on the services composition; According to (Shanchen et al) [6] who has a vision process on the services composition: "The composition is the selection process, combination and implementation services to accomplish a given objective. "…”

“…A second view more global is that of (Fekih et al) [5], "The composition then being an effective way to create, run, and maintain services that depend on other services. "…”

Adaptive and Optimized Meta-Heuristic Framework for Establishing QoS and Transaction Properties-based Dynamic Web Service Composition

“…It is capable in resolving the services which are included in the service composition process [7]. It is utilized to introduce the properties of the wireless communication depending on the number of web demands emerged in the network [8]. It is potent in accurate classification of the collection of candidate service set based on the user requirement tasks [9].…”
