Semantic Web. The Semantic Web is a collaborative movement led by international standards body the World Wide Web Consortium (W3C).[1] The standard promotes common data formats on the World Wide Web. By encouraging the inclusion of semantic content in web pages, the Semantic Web aims at converting the current web, dominated by unstructured and semi-structured documents into a "web of data". The Semantic Web stack builds on the W3C's Resource Description Framework (RDF).[2] According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries".[2] The term was coined by Tim Berners-Lee for a web of data that can be processed by machines.[3] While its critics have questioned its feasibility, proponents argue that applications in industry, biology and human sciences research have already proven the validity of the original concept.
History[edit] Purpose[edit] Limitations of HTML[edit] Semantic Web solutions[edit] 10 Semantic Apps to Watch. One of the highlights of October's Web 2.0 Summit in San Francisco was the emergence of 'Semantic Apps' as a force. Note that we're not necessarily talking about the Semantic Web, which is the Tim Berners-Lee W3C led initiative that touts technologies like RDF, OWL and other standards for metadata.
Semantic Apps may use those technologies, but not necessarily. This was a point made by the founder of one of the Semantic Apps listed below, Danny Hillis of Freebase (who is as much a tech legend as Berners-Lee). The purpose of this post is to highlight 10 Semantic Apps. We're not touting this as a 'Top 10', because there is no way to rank these apps at this point - many are still non-public apps, e.g. in private beta. It reflects the nascent status of this sector, even though people like Hillis and Spivack have been working on their apps for years now. What is a Semantic App? Firstly let's define "Semantic App".

Par Hubert Guillaud le 05/11/07 | 7 commentaires | 8,581 lectures | Impression Nova Spivack, le président de Radar Networks, s’apprête à lancer un outil en ligne, baptisé Twine, qui ambitionne de changer la manière dont nous organisons notre information.
Dévoilé au récent Sommet du Web 2, Twine est un site web où les gens pourront déposer l’information qui leur est importante, des mails, aux vidéos (voir la traduction du communiqué de presse réalisée par Jean-Marie Le Ray). Twine peut collecter toutes les pages que vous visitez ou les mails que vous envoyez et recevez, explique Kate Greene pour la Technology Review. Une fois que Twine est connecté sur vos données, il les analyse et automatiquement, les catégorise selon les concepts discutés, les personnes, les lieux, les organisations et les sociétés qu’ils concernent , afin de proposer une recherche facilitée. Twine respecte les standards du web sémantique, précise Nova Spivack, ce qui le rend compatible avec d’autres applications. Semantic Web: What Is The Killer App? The Semantic Web has been in the making for some time and people think it is nearing maturity. We have written about this trend extensively, with our two most notable posts being an analysis of the challenges of the classic bottom-up approach and the promise of the new top-down one.
Regardless of how the Semantic Web will come about, for it to flourish it needs to hit the mainstream. There is no way that consumers will appreciate the elegance and mathematical soundness of RDF and OWL. People don't care about math, they care about utility and even more, about fun. What the Semantic Web needs, then, is a killer app. Whatever it is, it needs to layer an understanding of semantics on top of a consumer application. In this post, we analyze several existing and potential applications of semantic technologies and look for the killer app. Natual Language Understanding Since the beginning, the Semantic Web has been associated with Artificial Intelligence.

Par Hubert Guillaud le 21/01/08 | 3 commentaires | 14,760 lectures | Impression Quelle sera l’application phare du web sémantique ? C’est la question que se pose Alex Iskold dans Read/Write Web, alors que le web sémantique, dit-il, “approche de la maturité”. Une maturité qui se jauge d’ailleurs à l’aune des premières applications publiques. Comme ces 10 applications sémantiques à surveiller qu’évoquaient le Read/Write web quelques semaines plus tôt. Un panel assez intéressant d’applications sémantiques en bêta ou déjà disponibles comme : Freebase, Twine ou ClearForest (dont nous vous avons déjà parlé) ;Powerset, TrueKnowledge et Hakia, les moteurs de recherche en langage naturel ;Spock, le moteur de recherche de personnes ;ou encore les outils de raccourcis comme Adaptive Blue ;ou encore TripIt, un agrégateur d’information autour du voyage.
On voit bien en tout cas, que c’est dans ces services-là qu’aujourd’hui les propositions sont les plus riches argumente Iskold. The Semantic Web Gang » Blog Archive » October 2008: The Semanti.
