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

Information retrieval (IR) systems are important key players for every Internet user and there are many Information Retrieving frameworks and algorithms, which are currently using or under development. As the technology trend is always changing and current industrial and business world is willing to emphasize on not only providing knowledge but also supporting service, cloud computing and Web Services (WSs) become popular. Cloud computing 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 research community. WS plays important role in service oriented computing in World-Wide-Web and Cloud environment. Developing a Cloud Wide IRSystem using WSs can fill one blank of Cloud Environment. In this case, retrieving desired specific information from WSs on Cloud Environment cannot be completed by single WS. Hence, there should be a way to build an IRSystem based on a set of related WSs in order to fulfill users' requests and provide desired services. To compose WSs, Multi-Agent System (MAS) can give great help. Agent systems are self-contained software programs embodying domain knowledge and having ability to act as a specific degree of independence to carry out actions needed to accomplish desired goals. Therefore, this paper mainly focuses on building a WSs Based IR MAS framework and Agent Processing Algorithm, which will be running on a Private Cloud 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.
