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.
