I've often joked that it is ironic that a term that contains the word "semantic" has such an ambiguous meaning for most people. Most people just have no idea what this means, they have no context for it, it is not connected to their experience and knowledge. This is a problem that people who are deeply immersed in the trenches of the Semantic Web have not been able to solve adequately -- they have not found the words to communicate what they can clearly see, what they are working on, and why it matters for everyone. In this article I have tried, and hopefully succeeded, in providing a detailed introduction and context for the Semantic Web for non-technical people. But even technical people working in the field may find something of interest here as I piece together the fragments into a Big Picture and a vision for what might be called "Semantic Web 2.0.""The meaning and the future of the semantic web" .

Dans le prolongement de mes billets RDF pour les nuls et A la découverte du Web sémantique , je vous propose de découvrir RDF en cinq minutes à travers quelques slides créés pour des formations au Web sémantique, que j'ai données ces dernières semaines. Il faudrait que je l'accompagne de l'explication de texte, mais le temps me manque... Il faudra donc s'en contenter ou vous référer aux différents billets de ce blog sur la question . PS : pour s'amuser, on fait un concours avec Manue : celui qui aura le plus de hit sur un diaporama sur son sujet favori . Alors, cliquez !

Explication sur la construction d'un tripplet RDF. by Mar 1
Ce deuxième screencast montre les opportunités du web sémantique via des exemples concrets issus du projet Linking Open Data . Ce projet est mené par le W3C , son objectif est de référencer les plus grandes sources de données sémantiques. Le projet le plus abouti de cette initiative est sans aucun doute dbpedia .En effet Wikipedia est de loin l’encyclopédie la plus grande au monde et est accessible gratuitement sur le web. Les éditions de Wikipedia sont accessibles dans plus de 250 langues différentes avec une version anglaise contenant plus de 2 millions d’articles. Malheureusement Wikipedia fournit un moteur de recherche qui se limite à la recherche de texte et de mots clés, ce qui réduit considérablement l’accès à cette base de données de grande valeur.Le web sémantique permet d’effectuer des requêtes explicites sur des informations structurées ainsi que sur des données liées sur différentes sources de données.

Common Tag
Depuis dejà quelques années, le tagging est entré dans les mœurs de bon nombre d’internautes. On trouve des tags partout : sur les blogs, sur YouTube, sur Flickr… Mais un problème de taille subsiste : quand vous mettez en ligne les photos de vos dernières vacances en Bretagne, les tagguez-vous “Saint Malo” ou “st malo” ? Comment s’assurer dès lors que vos contenus seront correctement identifiés, que d’autres contenus pertinents pourrons lui être associés ? Et quand vous rencontrez le tag “Orange”, comment savoir s’il s’agit de France Télécom ou d’un fruit ?
Livre: Programming the Semantic Web
Colophon The animal on the cover of Programming the Semantic Web is a red panda ( Ailurus fulgens , or "shining cat"), named for its bright, cinnamon-colored fur. Its resemblance to other animals has given it many nicknames, including firefox, cat bear, and lesser panda. Although predominantly red, it has white markings on its face and a black belly and limbs.
The Semantic Web is the logical next step in the evolution of the ENTIRE Web, and this book makes a strong case why its not all hype and a pipe-dream as some detractors would put it. And Jeff Pollock knows what he's talking about. A well-known figure in Semantic Web circles, he also manages Fusion - Oracle's middleware solution for the enterprise. In it, he clearly explains what's wrong with the current state of the Web, and how we manage and produce data in general. He shows how Semantic technologies can clear the way for computers and systems not only in helping us produce (and drown ourselves) in a sea of data, but actually help us consume and find information in it. Despite the "for Dummies" pejorative, the text is actually quite useful even for veteran Semantic Web followers.

Michael Hausenblas. We are currently working on a Technical Report about Linked Data Applications - The Genesis and the Challenges of Using Linked Data on the Web : Abstract: We are writing the year 2009. Three years after the linked data principles have been formulated by Tim Berners-Lee and two years after the grass-root community project 'Linking Open Data' has started to apply them to publicly available datasets such as Wikipedia, DBLP, and GeoNames, we are still at the very inception to understand how to use linked data in order to build Web applications and Web services.

Introduction to linked data
When a web site or web page is described as complying with web standards, it usually means that the site or page has valid or nearly valid HTML, CSS and JavaScript. The HTML should also meet accessibility and semantic guidelines. An honorary mention for One Web The Web is designed as a universal space. Its universality is its most important facet. I spend many hours giving talks just to emphasize this point.This book gives an overview of the principles of Linked Data as well as the Web of Data that has emerged through the application of these principles. The book discusses patterns for publishing Linked Data, describes deployed Linked Data applications and examines their architecture. The World Wide Web has enabled the creation of a global information space comprising linked documents. As the Web becomes ever more enmeshed with our daily lives, there is a growing desire for direct access to raw data not currently available on the Web or bound up in hypertext documents. Linked Data provides a publishing paradigm in which not only documents, but also data, can be a first class citizen of the Web, thereby enabling the extension of the Web with a global data space based on open standards - the Web of Data. In this Synthesis lecture we provide readers with a detailed technical introduction to Linked Data.
Livre : Linked Data: Evolving the Web into a Global Data Space
This document provides a tutorial on how to publish Linked Data on the Web. After a general overview of the concept of Linked Data, we describe several practical recipes for publishing information as Linked Data on the Web. This tutorial has been superseeded by the book Linked Data: Evolving the Web into a Global Data Space written by Tom Heath and Christian Bizer.
How to publish Linked Data on the Web
Your data is broken. You publish RDF data on the web, and thereby contribute to our shared passion: the emerging global information space that we call the web of data. Thank you for that! Thank you for sharing your data! But your data is broken.

LinkedData in action
Following the Online Information Conference 2009 , at which I demonstrated live examples of Linked Data in action, I have been asked several times if my presentation had been videoed. Unfortunately it had not. So I have tried to recreate the presentation, if not the atmosphere, by recording this screencast. In an attempt to find a quite uninterrupted environment, I recorded this early on a Sunday morning. I hope therefore you will forgive the odd clink of the first coffee cup of the day.Linked Data – thermo view
Though Linked Data (the set of principles) can be considered being around since roughly three years, the technologies it builds upon are around already considerable longer: two of the three core Linked Data technologies (URIs and HTTP) are some 20y old. And because I know that you’re at least as curious as I am I thought it might be nice to sit down and capture a more complete picture:In a conversation with data owners about how they should be publishing their data, it is usually not long before the following question turns up: “ So, what do I actually have to do to publish my data? ” Often the conversation then wanders off into a game of buzzword bingo–RDF, RDFa, SPARQL, dereferenceable URIs, triples, content negotiation, open data, Linked Data, end-points, etc.—to be followed by a blank look and the unuttered question " Yes, but what do I actually have to do to publish my data? ” Sounds simple. Just take the spreadsheet (or similar file) that you use to track information, post it on your web site and link to it from a description posted in an accompanying web page.
