Abstract

SEMANTIC WEB: WEB SERVICE DISCOVERY AND COMPOSITION FOR HEALTH SERVICES

Priyankadevi V.*, Michael Raj T.F. and Sivaprakasam P.

ABSTRACT

Web Service is a collection of open protocols and standards used for exchanging data between applications and systems. Web Service Discovery is the process of finding a suitable Web Service for a given task. Web service composition provides an open, standards-based approach for connecting web services. In web service composition set of web services collectively executed to achieve something. The existing approach makes use of iServe for web service discovery and Compos IT for web service composition which has some drawbacks during searching. The proposed approach uses PSO (Particle Swarm Optimization) algorithm for web service discovery. A basic variant of PSO algorithm works by having a population (called a swarm) of candidate solutions (called particles). The proposed approach also uses AHC (Agglomerative Hierarchical Clustering) for web service composition. AHC is a bottom-up approach, it starts with each service being a single cluster and eventually merges all services into one cluster. Finally, composite services are generated and it is used by the user.
