Multi-Agent Based Cloud Service Composition usingContract Net Protocol for Information Retrieval Purpose

Information retrieval (IR) systems are important key players for every Internet user and there are many InformationRetrieving frameworks and algorithms, which are currently using or under development. As the technologytrend is always changing and current industrial and business world is willing to emphasize on not only providingknowledge but also supporting service, cloud computing and Web Services (WSs) become popular. Cloudcomputing is internet based system development in which large scalable computing resources are provided“as a service” over the internet to users and has attracted more and more attention from industry and researchcommunity. WS plays important role in service oriented computing in World-Wide-Web and Cloud environment.Developing a Cloud Wide IRSystem using WSs can fll one blank of Cloud Environment. In this case, retrievingdesired specifc information from WSs on Cloud Environment cannot be completed by single WS. Hence, thereshould be a way to build an IRSystem based on a set of related WSs in order to fulfll users’ requests and providedesired services. To compose WSs, Multi-Agent System (MAS) can give great help. Agent systems are selfcontained software programs embodying domain knowledge and having ability to act as a specifc degree ofindependence to carry out actions needed to accomplish desired goals. Therefore, this paper mainly focuses onbuilding a WSs Based IR MAS framework and Agent Processing Algorithm, which will be running on a PrivateCloud Environment. We propose Contract Net Protocol for IR Purpose in order to perform WSs Composition.The implementation and testing of this system utilizes the real datasets of clinics in the Yangon area
