Berners-Lee regards today’s Web as a rebellious adolescent that can never fulfill his original expectations. By 2005, he hopes to begin replacing it with the Semantic Web—a smart network that will finally understand human languages and make computers virtually as easy to work with as other humans.
As envisioned by Berners-Lee, the new Web would understand not only the meaning of words and concepts but also the logical relationships among them. That has awesome potential. Most knowledge is built on two pillars: semantics and mathematics. In number-crunching, computers already outclass people. Machines that are equally adroit at dealing with language and reason won’t just help people uncover new insights; they could blaze new trails on their own.
Even with a fairly crude version of this future Web, mining online repositories for nuggets of knowledge would no longer force people to wade through screen after screen of extraneous data. Instead, computers would dispatch intelligent agents, or software messengers, to explore Web sites by the thousands and logically sift out just what’s relevant. That alone would provide a major boost in productivity at work and at home. But there’s far more.
Software agents could also take on many routine business chores, such as helping manufacturers find and negotiate with lowest-cost parts suppliers and handling help-desk questions. The Semantic Web would also be a bottomless trove of eureka insights. Most inventions and scientific breakthroughs, including today’s Web, spring from novel combinations of existing knowledge. The Semantic Web would make it possible to evaluate more combinations overnight than a person could juggle in a lifetime. Sure scientists and other people can post ideas on the Web today for others to read. But with machines doing the reading and translating technical terms, related ideas from millions of Web pages could be distilled and summarized. That will lift the ability to assess and integrate information to new heights. The Semantic Web, Berners-Lee predicts, will help more people become more intuitive as well as more analytical. It will foster global collaborations among people with diverse cultural perspectives, so we have a better chance of finding the right solutions to the really big issues—like the environment and climate warming.

Can privacy be preserved (2) bringing safety and security to a world that seems increasingly (3) ?
Last month, Howard Schmidt, the nation's cyber-czar, offered the federal government a (4) to make the Web a safer place a "voluntary trusted identity" system that would be the high-tech (5) of a physical key, a fingerprint and a photo ID card, all rolled (6) one. The system might use a smart identity card, or a digital credential (7) to a specific computer, and would authenticate users at a range of online services.
The idea is to (8) a federation of private online identity systems. User could (9) which system to join, and only registered users whose identities have been authenticated could navigate those systems. The approach contrasts with one that would require an Internet driver's license (10) by the government.
Google and Microsoft are among companies that already have these "single sign-on" systems that make it possible for users to (11) just once but use many different services.
(12) , the approach would create a "walled garden" cyberspace, with safe "neighborhoods" and bright "streetlights" to establish a sense of a (13) community.
Mr. Schmidt described it as a "voluntary ecosystem" in which "individuals and organizations can complete online transactions with (14) ,trusting the identities of each other and the identities of the infrastructrue (15) which the transaction runs".
Still, the administration's plan has (16) privacy rights activists. Some applaud the approach; others are concerned. It seems clear that such a scheme is an initiative push toward what would (17) be a compulsory Internet "drive's license" mentality.
The plan has also been greeted with (18) by some computer security experts, who worry that the "voluntary ecosystem" envisioned by Mr. Schmidt would still leave much of the Internet (19) . They argue that all Internet users should be (20) to register and identify themselves, in the same way that drivers must be licensed to drive on public roads.
