The Intelligent Wireless Web
How does the Web Learn?
The various 15 billion worldwide devices available today produce about 30% of all data communications. The Web may be the nexus of much of this information flow, but you must admit, it is not overly smart. In the future, however, the Web will need to do much more than pass raw data between people via search engines.
Facilities to put device-understandable data on the Web are becoming a high priority for many communities. Tomorrow's programs should be able to share and process data even when different applications and data sources are developed independently. The Semantic Web Â as advocated by the World Wide Web Consortium (see Inset) - is a vision of having data on the Web defined and linked in a way that it can be used by devices, not just for display purposes, but for automation, integration and reuse of data.
The Worldwide Web Consortium (W3C)
The Worldwide Web Consortium (see www.w3.org/) was created in 1994 and has grown to more than 500 member organizations from around the world. The objective of W3C is to lead the World Wide Web to its full potential by developing common protocols that promote its evolution and ensure its interoperability.
The Semantic Web
The Semantic Web can be considered to be the realization of a vision of the future in which data on the Web will be defined and linked in such a way that it can be readily used by machines, not just for display, but for direct use in various applications.
The technology now exists to realize the Semantic Web. We know how to build the terminologies and how to use metadata. The future vision depends on agreeing on common standards that can be used and extended everywhere.
Work is going on to realize tools and techniques, which will help to create the Semantic Web. For further information on the approaches being explored, visit the following Web page: http://www.semanticweb.org/.
Ideally, the wireless communication process should start by talking to a personal, or embedded, device that recognizes your words and commands. It will connect seamlessly to the correct transmission device drawing on whatever resources are required from around the Web. Perhaps only database search, sorting and retrieval are required. Or perhaps a specialized application program will be needed. In any case, the information will be evaluated and the content of your message with the appropriate supporting data to fill in the 'blanks' will be provided. If there is appropriate supplementary audio, or video, it will be included for reference. Finally, the results will be delivered to the appropriate parties in their own language through their own different and varied connection devices.
