In the same way that the Holy Roman Empire was neither holy nor Roman, Facebook’s OpenGraph Protocol is neither open nor a protocol. It is, however, an extremely straightforward and applicable standard for document metadata. From a strictly semantic viewpoint, OpenGraph is considered hardly worthy of comment: it is a frankenstandard, a mishmash of microformats and loosely-typed entities, lobbed casually into the semantic web world with hardly a backward glance.
Best Buy may be considered by many as a poster child for why businesses should use Semantic Web technologies. An early adopter of the GoodRelations vocabulary ( just recommended for product and price information usage in web pages by Google), the retailer has been at the forefront of the Semantic Web wave – but it’s only just begun. Semantic Web technologies, says Jay Myers, lead web development engineer at Best Buy, are a portal to better insight, in more ways than one (thoughts he’ll be sharing in more detail with attendees at this week’s Semantic Web Summit in Boston).
iGlue , which wants to “wikify the web“, has officially launched its semantic content organizer and search application. Three years in the making before being unveiled at TechCrunch Europe’s GeeknRolla event in London last April, iGlue creates an additional information layer over web pages by using natural language technology to understand its content. The browser plug-in or bookmarklet recognises names of relevant entities in text, such as people, geographical locations, institutions etc. and then when a user rolls their mouse over those entities, displays related information, images and videos.
Internetome , the U.K.'s first full day conference dedicated to the Internet of Things was held on Nov 10 in London. In front of a full attendance, with representatives from academia, government, and enterprise, a wide range of speakers illustrated the promise and the challenges of the complex systems based on smart sensor networks.

But, this one seems set to take off, unlike the seemingly eternal wait for so-called "semantic web" technologies to flourish - heck, emerge would suffice at this stage! According to Nova Spivack , from this post : A Web of Intent is a participatory web: a web where we’re active consumers of content. Webs of Intent are an extension of the remix culture that has emerged.
This site introduces ontologies and semantic web, with the emphasis on how ontologies are defined and used for semantic web applications today (more about this site background is here ). This tutorial is extracted from the introductory chapter of the dissertation that deals with the applications of ontologies in multi-agent systems - Marek Obitko (advisor Vladimir Marik): Translations between Ontologies in Multi-Agent Systems, Ph.D. dissertation, Faculty of Electrical Engineering, Czech Technical University in Prague, 2007 . Enough for introduction, you can choose the Next buttons to continue reading or select any topic of interest from the menu on the left.

Le Web sémantique, ou « langage naturel » est le Saint Graal sur lequel planchent les chercheurs depuis quelques années. Pour un de ses théoriciens, Tim Berners-Lee, l’idée est de parvenir à un Web intelligent, où les informations ne seraient plus stockées mais comprises par les ordinateurs, pour apporter à l’utilisateur ce qu’il cherche vraiment. Le Web sémantique permettra donc de rendre le contenu sémantique du Web interprétable non seulement par l’homme, mais aussi par la machine.
RDF is defined as an abstract data model, plus a collection of practical notations for exchanging RDF descriptions (eg. RDF/XML, RDFa, Turtle/N3). In theory, your data modelling activities are conducted in splendid isolation from the sleazy details of each syntax. RDF vocabularies define classes of thing, and various types of property/relationship that link those things. And then instance data uses arbitrary combinations of those vocabularies to make claims about stuff. Nothing in your vocabulary design says anything about XML or text formats or HTML or other syntactic details.
Yesterday we wrote about the increasing usage of Semantic Web technologies by large commercial companies like Facebook, Google and Best Buy. The Semantic Web is a Web of added meaning, which ultimately enables smarter and more personalized web apps to be built. In this post we explore how a leading U.S. retailer, Best Buy , is using a Semantic Web markup language called RDFa to add semantics to its webpages. This is not just an academic exercise for Best Buy. As we will see, semantic technology has already led to increased traffic and better service to its customers. We spoke to Jay Myers , Lead Web Development Engineer at BestBuy.com, to find out how.
In an hour long interview posted today about the Semantic Web, W3C Director Tim Berners-Lee says all the pieces are in place to move full steam ahead and realize the potential of a world of structured, machine readable data. Available as a part of the Talking with Talis semantic web podcast series, the interview ( listen here ) is summarized on interviewer Paul Miller's new ZDNet blog dedicated to the semantic web. A full transcript is available here . It's an important conversation and a good introduction to what the semantic web is. Also notable is the way that Berners-Lee sees Semantics and Data Portability as very related. Some highlights are excerpted below.
During an interesting session called the ‘Great Global Graph’ at the CETIS conference this week I formed the opinion that, in the recent rush of enthusiasm for ‘linked data’, three ‘memes’ were being conflated. These next three bullets outline my understanding of how these terms have been used in recent discussions, including the CETIS session: Open data: I see this as something expressed as a philosophy or, in more concrete terms, as a policy, such as that espoused by the UK Government. There are aspects of public ownership in this, but also a philosophical approach based on ‘openness’ and a rejection of the economic idea of value in scarcity of information. I think that specific technology does not come into this really: for example one concrete realisation of this policy in the UK is the Freedom of Information Act under which it is perfectly permissible for a data owner to supply data in any reasonable format and medium.
Quand la donnée prend le dessus. C’est ainsi que pourrait être, très vulgairement, résumé le Web sémantique. Un vaste projet qui a éclaté aux yeux de tous suite à l‘intervention de Tim Berners-Lee, patron du W3C - et également père du Web -, le consortium en charge de définir les standards du Web. Dans un entretien réalisé par l e Courrier Unesco en 2000 , il est parvenu à transmettre sa vision d’un autre web.
The Semantic Web The Semantic Web is a big step toward Web 3.0, where the ultimate goal is to make Web content more machine-friendly. Most Websites are produced using HTML, which is a markup language used to make a Website “look” a certain way.
Socialmedia.biz contributor Deltina Hay now has a featured column on Technorati called You’ll Be Back: Search Optimization & Survival . The column focuses on search optimization as it applies to the entire Web: search engines, social search, mobile search, the semantic Web, etc. You can read the articles right here on Socialmedia.biz every week.
Le web 2.0 a-t-il fait long feu? «C’est vraiment aisé, pour n’importe qui, de mettre un peu d’Ajax dans une page, d’ajouter quelques tags et de réaliser une jolie interface utilisateur. Mais ça ne suffit pas pour créer une valeur durable», juge sévèrement Nova Spivak, le créateur de Radar Network. Avec sa société, il veut apporter une nouvelle dimension au web, transformer un simple catalogue en un guide intelligent, avec lequel l’utilisateur pourra interagir sur un mode beaucoup plus naturel. La force des applications du web 2.0, en général accessibles depuis un simple navigateur, est de s’appuyer sur des " mash-ups ", ces remix de différents services qui ajoutent des couches plus pratiques et fonctionnelles au web.
