The convergence of telecommunications, mass media and computer technologies has brought spectacular developments of ubiquitous intelligent interconnected systems. In the course of these evolutionary changes, debate and policy has swung again towards privatization, deregulation and increased reliance upon competition. Nevertheless, the underlying and powerful role of new information continues to bring so much restructuring and organizational change, that a reassessment of ideas about competition in this dynamic context, is essential. The aim of this volume is to provide an update of research...

Global changes in policy and technology in the telecommunications industry in the 1990s are described and analyzed in this volume, showing how this industry creates a bridge for society's transition to the next century. Dynamic innovations in technology are encouraging a relatively free world market and a Global Information Infrastructure for use by developed and developing economies. The volume discusses the challenges posed by these innovations for closing the gap between the information-rich and information-poor. Lessons are included for corporate and individual users as they prepare for...

Telecommunications systems are central to the development of a global economy, and are fundamental to the means by which most business is conducted, organised and managed. Supported by recent sophisticated econometric analyses, the International Telecommunications Union considers the link between telecommunications and economic development to be axiomatic. This volume takes a broader view. Four themes are considered: Telecommunications and Development focuses on new technology diffusion, and the regional impact of telecommunications investment. International Dimensions provides an examination...

The Semantic Web is an idea of World Wide Web inventor Tim Berners-Lee that the Web as a whole can be made more intelligent and perhaps even intuitive about how to serve a users needs. Although search engines index much of the Web's content, they have little ability to select the pages that a user really wants or needs. Berners-Lee foresees a number of ways in which developers and authors, singly or in collaborations, can use self-descriptions and other techniques so that the context-understanding programs can selectively find what users want.

The Semantic Web: Crafting Infrastructure...
