Web service composition techniques based on semantics: A comparative study

Web services are considered as modular, self describing units of application that can be hosted across the web and accessed from other applications. Web service composition is a technique in which two or more existing web services are combined together as a complex web service to satisfy the user requirements. The automated service composition is done with less human intervention. Many researchers did their work in service composition using technologies such as Artificial Intelligence (AI), Fuzzy Predicate, Service Agent, Constraint Aware Composition, heterogeneous In this work, we analyse the recent automated web service composition techniques. The comparative analysis of various performance metrics is also given. This paper helps the researchers to find the best approach in the field of service composition.
