Towards Building a Semantic Grid for E-Government Applications

چکیده
Nowadays, there is a growing number of e-government portals and solutions that provide integrated governmental e-services to the customers (citizens, enterprises or other public sectors). However, the administration and interoperability of distributed e-government nodes are faced with increasing challenges caused by the service-oriented modeling difficulties and ontological issues in distributed computing, resource integration and knowledge sharing over heterogeneous computing platforms. To overcome this, a Semantic Grid infrastructure is presented in this paper for distributed management of e-government resources across ubiquitous virtual governmental agencies. An ontology-based service-oriented approach to problem-solving in e-government is proposed in the Semantic Grid, enabling to provide, in an open, dynamic, loosely coupled and scalable manner, the service publication, discovery and reuse for connecting the customers and agencies of egovernment services based on their semantic similarities in terms of problem-solving capabilities. The operation of the system is demonstrated using Protégé-2000, a widely accepted ontology modeling tool to validate the implementation of the proposed approach towards effective ontological maintenance.

Towards a Language Infrastructure for the Semantic Web
In recent years, the Internet evolved from a global medium for information exchange (directed mainly towards human users) into a ”global, virtual work environment” (for both human users and machines). Building on the world-wide-web, developments such as grid technology, web services and the semantic web contributed to this transformation, the implications of which are now slowly but clearly bei...
متن کاملTowards Building a Semantic Grid for E-Learning
In an E-learning scenario, educational resources, such as course documents, videos, test-bases, courseware, and teacher information etc., are shared across different schools. DartGrid is built upon several techniques from both Semantic Web and Grid research areas, and is intended to offer a semantic grid toolkit for data integration. In this paper, a Semantic Grid for E-leaning based on DartGri...

متن کاملIRS-III: A Broker for Semantic Web Services Based Applications
In this paper we describe IRS-III which takes a semantic broker based approach to creating applications from Semantic Web Services by mediating between a service requester and one or more service providers. Business organisations can view Semantic Web Services as the basic mechanism for integrating data and processes across applications on the Web. This paper extends previous publications on IR...
