What is the Semantic Web really all about?

What is the Semantic Web really all about?
The Semantic Web is based on the relatively straightforward idea that to be able to integrate (link) data on the Web we must have some mechanism for knowing what relationships hold among the data, and how that relates to some “real world” context. The following is a lot of detail that comes from this simple idea. To answer this question properly, let me start back in the early Web era. While I’m going to do some potentially boring personal history, I’ll note the key ideas as I go along. Slogan: A little semantics goes a long way key idea 1: SIMPLE key idea 2: URI-based Another student, Jeff Heflin (now a faculty member at Lehigh) started playing with this idea and extended it to include a rule-based reasoner, a Web scraper for extracting SHOE from non-annotated Web sites, a visual query by example system and a bunch of other things. “Linked Data” (or “Web of Data”) – close to the original vision.

The Semantic Web Acid Test Tom Heath writes a cracking post on the current attempts by a few people to brand web applications that happen to perform text analysis as “Semantic Web”. For me, this nails it: I certainly notice plenty of unjustified attempts at present to co-opt the term Semantic Web, now that it’s no longer a dirty word, and drive it off down some dodgy alleyway. Some of these products, services or companies may be applications or services that use some semantic technology and are delivered over the Web, but that doesn’t make them Semantic Web applications, services or companies. Anything claiming the Semantic Web label needs to get its hands dirty with Linked Data somewhere along the way. Tom’s right. Like this: Like Loading...

What is Web 3.0? Semantic Web & other Web 3.0 Concepts Explained Web 3.0 will be about semantic web, personalization (e.g. iGoogle), intelligent search and behavioral advertising among other things. This slide neatly sums up the main differences between Web 1.0, Web 2.0 and Web 3.0. Web 1.0 – That Geocities & Hotmail era was all about read-only content and static HTML websites. Web 2.0 – This is about user-generated content and the read-write web. Web 3.0 – This will be about semantic web (or the meaning of data), personalization (e.g. iGoogle), intelligent search and behavioral advertising among other things. If that sounds confusing, check out some of these excellent presentations that help you understand Web 3.0 in simple English.

Main Page - Semantic Web Standards What to expect from Web 3.0 | Software as Services | ZDNet.com Any veteran of the software industry will tell you that version 2.0 of any product tends to be a shortlived staging post on the way to 3.0, which is where it finally hits the mark. Windows was a classic example. 1.0 was so buggy it was hardly worth using. 2.0 fixed some serious problems but still had a lot of shortcomings. 3.0, launched in May 1990, was an instant success, and the rest of the story, as they say, is history. Don't be surprised, then, if Web 2.0 also turns out to be just a staging post on the way to a much more mature and durable Web 3.0 is going to deliver a new generation of business applicationsWeb 3.0 era. I'd like to make one thing is absolutely clear right from the outset: Web 3.0 isn't just about shopping, entertainment and search. Today I'm going to start by mapping out a brief topology of Web 3.0. API services form the foundation layer. Aggregation services form the middle layer. Serviced clients are the 'and-a-half' layer I mentioned earlier.

Article très interessant sur l'histoire du web sémantique. James Hendler insiste sur le fait que la vision historique du web sémantique est de lier les données et que cela ne nécessite en rien l'utilisation d'ontologies compliquées. by nicolas Jul 4
