Building a composite web service as per the user's complex need requires using the multiple online web services available. Selecting the best web service for composition will become combinatorial problem leads to be the NP (Nondeterministic Polynomial) complete problem. To solve this problem they are proposing a framework for composite web service using ant colony optimization algorithm. For choosing the proper path selection, the authors are negotiating with individual web service to select it for the participation during composite web service. For negotiation they are using intelligent agents for analyzing web services for based on semantic, WSDL (Web Services Description Language) and QoS (Quality of Service) description. As per the profile of the users the negotiation agents are built for building composite web services.
