Par Guillaume Noé • Jan 30th, 2008 • Catégorie: Web sémantique Ma première fois avec le web sémantique, j’ai trouvé le concept génial mais je n’ai rien compris. Qu’est-ce donc que cette chose savante? Encore une nouveauté 2.0?
[ translations into other languages ] The world of the semantic web, as based on RDF, is really simple at the base. This article shows you how to get started.
Presentation by Paul Storey, Director Stakeholder Relations and Strategic Communications, Pharmaceutical Evaluation Branch. Paul started off with comparing himself with The Monkees so automatically he has credit :) Paul assured us that he isn't here on public service time with a sly reference to grogsgamut as well as giving us a profile of his social media footprint. Paul gave us the background of the pharmaceutical guide and why they moved it online to make it easier for access.
Stories of despair in the geek world started to overwhelm the Web.
Did you ever think about becoming Editor-in-Chief of your own newspaper? Well, Paper.li can score you that gig. In an automated process, those you follow on Twitter and the links included in their tweets, can essentially become the subject matter of your own daily online newspaper that you can create in less than 5 minutes. As social media generates real-time news, it can now interface with Paper.li to not only publish this news onto a micro-site, it will also tweet it out to all of one's Twitter followers daily. Social Media Scientist Daily by Ron Callari Curation of existing Web content is being explored by a number of semantic technology companies today, like Adaptive Semantics that's been generating content for the Huffington Post (see previous post, " HuffPo & The 'Wisdom of Machines' Crack Open Semantic Web Portal ").

This series on the semantic web started with an introduction in Part I. In Part II, I made the business case for going semantic. Part III focused on complementary technologies . In Part IV, I provided a case study of how one company is already successfully reaping the benefits of the semantic web.
How the pull paradigm and the semantic web combine to help businesses face the challenges of the future. The Problem On the Web today, we see millions of web sites, each of which presents web pages and documents. These are simply electronic versions of the old paper-based ways of doing things: writing checks, filing taxes, looking at menus, catalog pages, magazines, etc. When you search for something on Google, you get a list of web sites that may or may not have what you’re looking for, based on keywords found in the text.
The core Semantic Web technology is RDF, a W3C standard that reduces all data to three-part statements known as triples . If your data fits into the triple data model and is stored in one of the specialized databases known as triplestores , the advantages of Semantic Web technology are obvious. This doesn't mean, though, that the technology has nothing to offer you if your data is in more traditional formats such as relational databases and spreadsheets. Open source and commercial tools are available to convert data in these formats to triples, giving you an easy way to combine data from multiple sources using different formats.
Exemple d'utilisation de Dbpedia Labs > Exemples d'utilisation de Dbpedia Cette page rassemble une série d'exemples d'utilisation de DBpedia.org, qui propose les données de Wikipedia sous une forme structurée grâce à RDF. A ce titre, ces exemples ne proposent pas de graphisme ou de design travaillé et leur pérennité n'est pas assurée.
In general, semantics is the study of meaning. (The word "semantic" comes from the Greek semantikos, or "significant meaning," derived from sema, or "sign.") Semantic Web technologies help separate meanings from data, document content, or application code, using technologies based on open standards. If a computer understands the semantics of a document, it doesn't just interpret the series of characters that make up that document: it understands the document's meaning. The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries. You can think of the Semantic Web as an efficient way to represent data on the World Wide Web, or as a database that is globally linked, in a manner understandable by machines, to the content of documents on the Web.
Yogi Berra once said, “It’s like deja-vu, all over again.” With regard to new technologies, the same continues to hold true: The technologies themselves might be new, but they are fundamentally addressing old problems. Many of today’s emerging technologies such as cloud computing, SaaS, MDM, and social networks are really attempts to deal with core business issues. These include: Cost Communication Collaboration Data integrity Access to data Network reliability Scale The eternal battle to do more with less And many, many others
First of all, since ARML (augmented reality markup language) is based on KML and KML uses „Placemarks“ (which all have corresponding identifiers) as basic entities, these could be identified quite easily via URIs within the W3C Resource Description Framework (RDF) . Another basic concept of KML is „Point“. Geo RDF provides properties like „geo:long“ or „geo:lat“ which express longitude and latitude of a POI and thus makes it possible to uniquely identify certain points on a map using RDF standards. Thus it is possible to map the geo conventions of ARML to the geo conventions of the Semantic Web which are mainly based on Geo RDF. As soon as a placemark has received a URI it is also possible to expose it as linked data and interlink it with repositories like Geonames , DBpedia or LinkedGeoData (which is based on Open Street Map ) to generate Linked Geodata. ARML makes it possible to link / make a relation between a „Provider“ and a „Placemark“.
Don't get too excited by the title. But I do want to share a few thoughts... It was running through my head just now, the work that we were doing here in Moncton to work on an e-learning cluster. Because I saw that 'cluster building' is still one of the major pillars of NRC's strategy, and I was wondering whether our work would ever be a part of that again.
This is my collection of weblogs or sites with Semantic Web topics that I've found. Let me know any updates. Dave Beckett
