Description
Autonomous Semantic Grid (http://asg.niit.edu.pk)
This project comes in the domain of Distributed Computing. Distributed Computing has three major emerging areas like Web Services Framework, Grid Computing and Multi Agent Systems. Web Service Framework is based on principles of service oriented computing for providing loosely coupled, implementation neutral and heterogeneous resources. Grid Computing focuses on coordinated resource sharing among dynamic virtual organizations. Basic Grid Computing infrastructure then evolved to OGSA by adopting Web Services Framework. It can be defined as Open Grid Services Architecture (OGSA) that supports creation, termination, management, and invocation of state-full, transient services as named, managed entities with dynamic, managed lifetime via standard interfaces and conventions. Multi Agent Systems focuses on systems in which intelligent Software Agents interact with each other. The Agents are autonomous entities that can control their own state. Different Agents can share a common goal or they can pursue their own interests. Multi Agent Systems develop communications languages, interaction protocols, and agent architectures. Autonomous Semantic Grid project is aimed to provide a framework for open distributed systems and is based on synergy of Web Services, Grid Computing and Multi Agent Systems. By synergy we mean that it would combine properties of the three technologies without disturbing existing specifications to enable semantic interoperability of autonomous entities with each other, and semantically rich description of resources in Grid environment for better utilization. Software Agents will be able to discover resources in grid, form dynamic workflow, compose services, negotiate with other services or Agents to fulfill the agenda of goals.
There exist several issues in order to achieve synergy of Software Agents, Grid Computing and Web Services . These are due to inherent gap in service discovery, service description and communication protocol specifications of software agents and web services (act as basis for Grid in WSRF). There is need of establishment of a paradigm for integration of Software Agents and Web Services. We also call it as interoperability among Software Agents and Web Services. Web services lacks in capabilities than software agents. Web services are needed to be semantically enriched. For this a W3C compatible ontology is needed to be proposed and design which would add as semantics over existing service description of web services. After proposition of the standard ontology, software is to be developed which should automate the process of incorporating the proposed ontology into the existing web service description. There is also one inherent lack in the capability of software agents that they can
