Interoperability Integrating E-Government Portals

In recent years, we have witnessed the rapid evolution of the World Wide Web. This development allowed millions of people all over the world to access, share, interchange, and publish information. In this context, many governments have realized that their information resources are not only of value in themselves. They are valuable economic assets— the fuel of the knowledge economy. By making sure the information they hold can be readily located and passed between the public and private sectors, taking account of privacy and security obligations, it will help to make the most of this asset, thereby driving and stimulating national and international economy. The governments take advantage of information and communication technologies (ICTs) and the continuing expansion of the Web and started e-government strategies to renew the public sector and eliminate existing bureaucracy and therefore reduce costs (Riedl, 2003; Tambouris, Gorilas, & Boukis, 2001).
