Agent Based Cloud Service Composition for Information Retrieval purpose using IR-CNP

Abstract

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 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. Web Service plays important role in Service Oriented Computing (SOC) in World-Wide-Web and Cloud environment. Developing a Cloud Wide Information Retrieval System using Web Services can fill one blank of Cloud Environment. In this case, retrieving desired specific information from Web Services on Cloud Environment cannot be completed by single Web Service. So, there should be a way to build an Information Retrieval System based on a set of related Web Services in order to fulfill users’ requests and provide desired services. To compose Web Services, Multi-Agent System 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 Web Services Based IR Multi-Agent System framework and Agent Processing Algorithm which will be running on a Private Cloud Environment. We propose Contract Net Protocol for Information Retrieval Purpose (IR-CNP) in order to perform Web Services Composition. The implementation and testing of this system utilizes the real datasets of clinics in the Yangon area.
