What is the Semantic Web really all about? › Web Science - the World of the World Wide Web
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. Circa 1995, my research group began playing with an idea (first proposed by my then student Sean Luke now a faculty member at GMU) that if web markup (it was all HTML back then) contained some machine readable “hints” to the computer, then we could do a better job of Web tasks like search, query, and faceted browsing. “Linked Data” (or “Web of Data”) – close to the original vision.

Web 3.0 : aux gros mots, les gros remèdes ! Vous aimez « Person of interest » sur TF1, série dans laquelle deux héros sauvent de futures victimes en croisant des milliards de données rendues prédictives ? Tant mieux, car la réalité est en train de rejoindre la fiction. C'est bien, c'est mal, la question ne se pose plus vraiment car c'est là. Le big data arrive et vous êtes concernés, à titre personnel et dans celui de la gestion de la Cité. 10 % seulement de la masse des informations disponibles aujourd'hui ont été générées entre la création du monde (ça fait donc un bail) et 2011 inclus, le reste soit 90 % ayant été produit au cours des deux dernières années. Et la même proportion va se reproduire tous les deux ans, de façon exponentielle.

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.

La boîte à souvenirs A l'image de Michel Rolland et de, certainement, beaucoup d'autres, je me suis posé des questions sur la survie de Flick'r au moment de l'offre de rachat de Yahoo ! par Microsoft. Même si ces dernières n'ont pas abouti, mes interrogations ne m'ont pas quitté, d'autant plus que Flick'r ne semble pas une priorité de Yahoo !. Or, je préfèrerais récupérer mes données, avant d'être dans la situation que décrit Karl dans ce billet. Mes besoins

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. People preferred navigating the web through link directories of Yahoo! and dmoz. Web 2.0 – This is about user-generated content and the read-write web. Design Issues Up to Design Issues The Semantic Web isn't just about putting data on the web. It is about making links, so that a person or machine can explore the web of data. With linked data, when you have some of it, you can find other, related, data. Like the web of hypertext, the web of data is constructed with documents on the web.

What to expect from Web 3.0 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. Over the next couple of weeks I'm going to be writing a series of posts about what I see as the key characteristics of Web 3.0, using a variety of on-demand companies by way of illustration. Of course I'll be mentioning Google, and eBay. But don't assume these companies will inevitably become the dominant players of Web 3.0.

RWW Tim Berners-Lee, Part 1 During my recent trip to Boston, I had the opportunity to visit MIT. At the end of a long day of meetings with various MIT tech masterminds, I made my way to the funny shaped building (see photo right-below) where the World Wide Web Consortium (W3C) and its director Tim Berners-Lee work. Berners-Lee is of course the man who invented the World Wide Web 20 years ago. This was my first meeting with the Web's creator, whose work and philosophy was a direct inspiration for me when I launched ReadWriteWeb back in 2003.1 Top 10 Semantic Web Products of 2009 2009 has seen a lot of Semantic Web and structured data activity. Much of it has been driven by Linked Data, a W3C project which gained momentum this year. According to Sir Tim Berners-Lee, the inventor of the Web, Linked Data is a sea change akin to the invention of the WWW itself. We've gone from a Web of documents to a Web of data. The 10 products we've picked out for this end-of-year review are ones that have done interesting things with data.

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
