Web 3.0 is getting attention
PC Magazine (link) has an interesting overview of Web 3.0 on page 74 of the April 10, 2007 issue. The article, by Cade Metz, is “Web 3.0: The Internet is changing … again.” The buzzword is “semantic web,” which W3C (the World Wide Web Consortium) characterizes as a “web of data”, link here: A closely related concept is the Resource Descriptor Framework (RDF).
The idea is to navigate the web through the data itself, with a kind of human or mammalian intelligence. One weakness of the way we work now is that, while we can link all we like (and use embedded images or links, sometimes transparent to users – with some legal risks) and we can search for keywords in any combination we like, we really can’t link up “meaning” very well yet. One problem that is bothering employers, for example, is that they can find the names of associates on the web in combinations with derogatory words, but the results may not mean anything. There is nothing that tells you what a file means, or what the publisher’s intention was in putting it up. Other problems are linguistic. English and Chinese are “analytic” languages with lots of little words; other languages use endings (conjugations and declensions) to achieve meaning.
The PC article gives a detailed example of a patient scheduling all of the services associated with a medical appointment. But really, a really semantic web would help us understand different patterns in the way people think, in contrasts, an idea I have discussed before.
