À propos des extraits de code enrichis et des données structurées - Centre d'aide Outils pour les webmasters. Extraits de code enrichis (microdonnées, microformats, RDFa et marqueur de données) Les extraits, les quelques lignes de texte qui s'affichent sous chaque résultat de recherche, sont conçus pour donner aux internautes un aperçu du contenu de la page et leur montrer la pertinence du résultat par rapport à leur requête. Si Google interprète correctement le contenu de vos pages, nous pouvons créer des extraits enrichis, c'est-à-dire des informations détaillées visant à aider les internautes lors de recherches spécifiques.

Par exemple, l'extrait enrichi pour un restaurant peut indiquer sa note moyenne et un ordre de prix. L'extrait enrichi d'une recette de cuisine peut contenir une photo et indiquer la durée totale de préparation ainsi que la note attribuée à la recette, une photo et la note moyenne de la recette. Enfin, l'extrait enrichi d'un album musical peut contenir la liste des titres avec un lien permettant de lire chacun d'entre eux. 1. 2. 3. Et c'est tout ! Remarque : Siri and the Semantic Web. If you haven’t heard, the iPhone 5 just came out. Over 2 million people pre-ordered it within 24 hours of it going on sale.

There are a lot of reasons why people rushed to buy it, but Siri wasn’t one of them. Although the iPhone 5 is adding new abilities to Siri like making dinner reservations and getting sports scores, Siri will be just as arbitrary as it has been in the past. It’s not Siri’s fault. To understand why Siri was the best idea that hasn’t work out, we need to understand the semantic web and why we’re not there yet.

What the web is today and what it’ll be tomorrow For those that don’t follow the history of the web and how it has changed over the last 30 years, I’ll spare you the details. But what’s next? Examples for what’s to come in Web 3.0 Currently, Siri accepts only a few commands that it can actually act upon. Seems simple right? How it works (getting a little more complicated) <item rdf:about=" What this means for you. How Siri Works – Interview with Tom Gruber, CTO of SIRI.

Sneak Preview of Siri – The Virtual Assistant that will Make Everyone Love the iPhone, Part 2: The Technical Stuff In Part-One of this article on TechCrunch, I covered the emerging paradigm of Virtual Assistants and explored a first look at a new product in this category called Siri. In this article, Part-Two, I interview Tom Gruber, CTO of Siri, about the history, key ideas, and technical foundations of the product: Nova Spivack: Can you give me a more precise definition of a Virtual Assistant?

Tom Gruber: A virtual personal assistant is a software system that Helps the user find or do something (focus on tasks, rather than information)Understands the user’s intent (interpreting language) and context (location, schedule, history)Works on the user’s behalf, orchestrating multiple services and information sources to help complete the task In other words, an assistant helps me do things by understanding me and working for me. Tom Gruber: In general my answer is that Siri is more focused.

The semantic web in translational medicine: current applications and future directions. Catia M. Machado*Catia M. Machado is a PhD student at the Department of Informatics of the Faculty of Sciences and at INESC-ID, of the University of Lisbon. Her research interests are data representation and integration, in particular with semantic web technologies, knowledge discovery and translational medicine. Dietrich Rebholz-SchuhmannDietrich Rebholz-Schuhmann (PhD) is ‘Oberassistent’ (similar to Associate Professor) with the University of Zürich, Department of Computational Linguistics.

His research interests are biomedical literature and data analysis, data integration and knowledge discovery. Ana T. Abstract Semantic web technologies offer an approach to data integration and sharing, even for resources developed independently or broadly distributed across the web. Biomedical research has evolved into a data-intensive science, where prodigious amounts of data can be collected from disparate resources at any time [1]. Figure 1 Knowledge workflow in translational medicine.

Nine Ways the Semantic Web of Data Will Change Marketing. In marketing, data is power. But up until recently, the flow of data has been a one-way street. Data is collected at the point of sale, through market research and web analytics. Over the last decade, the volume of data available has grown exponentially to the point of becoming overwhelming. And yet, marketers derive little value from much of the data they collect, because it is largely unconnected and disorganized. The Semantic Web links and organizes data, making it more useful and insightful to marketers.

The Semantic Web is changing how marketers think about and use data. Linked Data-Semantic advertising will make it possible for advertisers to create sponsored metadata--semantic web data about the people, places, things, etc. listed in a webpage--so advertisers can bid to associate their metadata with names, facts or events. Mashable Data-Mash-ups pull data from multiple sources to create a new application, page or function.

NetAppVoice: How The Semantic Web Changes Everything. Again! The “semantic Web” is hugely important to tomorrow’s business. Do not underestimate its significance: It truly changes everything. Embrace it, or risk extinction. But what is it? And what does it mean for your business? “Semantic” is the latest buzzword to hit the online world. From semantic search to the semantic Web; and from semantic marketing to semantic technologies, it seems like everyone wants to ride the semantic train. But let’s take things from the beginning. So What? It marks the transition into a new phase of the Web, where we stop searching and start finding. In other words, we discover not just the information that matches the keywords we search for, but the information that we really wanted to find.

This is exactly what is happening with Google GOOG +0.27%’s semantic search, which finds content in direct response to the intent of our search query.

Technology | Berners-Lee on the read/write web. In August 1991, Sir Tim Berners-Lee created the first website. Fourteen years on, he tells BBC Newsnight's Mark Lawson how blogging is closer to his original idea about a read/write web.

Mark Lawson: Because of your invention, I was able to look up every article written by or about you quickly and easily. But at the same time, I was sent several unsolicited links to porn sites. I have to accept that someone in Mexico may have stolen my identity and now be using it. Is the latter absolutely worth paying for the former? Tim Berners-Lee: That's an interesting question that you ask, as though it's a yes or no answer. I feel that we need to individually work on putting good things on it, finding ways to protect ourselves from accidentally finding the bad stuff, and that at the end of the day, a lot of the problems of bad information out there, things that you don't like, are problems with humanity. ML: When you think in terms of what it has allowed, what is the achievement of the web? Plenary talk by Tim BL at WWWF94: Overview. This is an incomplete collection of slides which I promised to put on the web and didn't get around to for a long while -- sorry!

[These are from my talk a the very first International World Wide Web Conference, at CERN, Geneva, Switzerland, in September 1994. This was the conference at which the formation of W3C was announced]. The images are available multiple formats. If you can't see them properly, see the diagnostics page. on the need for a more collaborative space, with synchronous colboration and annotation Let me go into one future development direction in more detail. This is an arbitrary choice, perhaps because it is an issue which has been covered less than some of the others. This is the classic picture of hypertext which used to be a part of talks in the days when we had to explain what hypertext is. To a user, this has become an exciting world, but there is very little machine-readable information there. To a computer, then, the web is a flat, boring world devoid of meaning. Big data. L’alliance du Big Data et de la technologie RFID en passe de révolutionner l’industrie.

Le phénomène Big Data est désormais plus qu'un mot à la mode. Il devient une réalité concrète au même titre que la révolution de l'information joue un rôle de plus en plus crucial dans la croissance de tous les secteurs de l'industrie. A l’heure où les industries recherchent des solutions complètes de gestion de données pour exécuter leurs opérations et résoudre toutes sortes de problèmes, nous verrons que la technologie RFID devient l’outil du futur dans la gestion des Big Data. Comparé à l'étiquetage code à barres traditionnel, le tag RFID donne accès à des capacités de stockage de données supérieures tout en offrant une capacité de lecture plus élevée dans un laps de temps plus court. Les avantages de l’utilisation de la technologie RFID pour gérer de manière efficace les grands volumes de données dans de nombreux secteurs professionnels verticaux n’étant plus à prouver, cette technologie offre désormais la possibilité de révolutionner le monde de l'industrie.

Big Data et CRM. Depuis une quinzaine d'années, c'est-à-dire depuis l'avènement de l'internet commercial, de toutes les directions fonctionnelles de l'entreprise, c'est certainement la direction du marketing dont l'écosystème applicatif s'est le plus transformé. Gestion de campagnes, gestion d'enquêtes, gestion de 'leads', community management, veille sociale, e-reputation, les outils dédiés au marketing se sont multipliés. La direction du marketing est aussi celle qui s'est le plus tôt emparée des produits numériques, autrement dit de prestations en mode 'Saas'. Les limites des projets tactiques Cette approche tactique a ses avantages : la direction marketing a pu se rendre opérationnelle sur de nouvelles technologies, dans un délai et pour un coût raisonnables , et sans passer par les affres d'une gestion de projet SI traditionnelle.

L’autre sémantique - Le Web Sémantique et les systèmes de recherche d’information. [3.3] 3. Le Web Sémantique : une utopie condamnée ou une révolution en marche ? 21 octobre 2006, par Cariboo Le Web Sémantique à ses militants inconditionnels, mais aussi ses pourfendeurs et ses détracteurs. Le débat porte sur le caractère utopique ou non de la démarche. Certains pensent que c’est une idée géniale, et qu’il est vital d’avancer le plus vite possible dans cette direction qui, de toute façon, finira par s’imposer. D’autres pensent que pour des raisons psycho-sociologiques, sociétales, politiques, commerciales, le web sémantique ne peut pas se généraliser car il demande une trop grande discipline. Les arguments des inconditionnels du web sémantique Pour caricaturer, les arguments ressemblent au slogan du Loto : le web sémantique, c’est facile, c’est pas cher et ça peut rapporter gros L’apport du web sémantique serait immense.

Le Web Sémantique offre un grand nombre de possibilités pour de nouvelles applications d’outils de recherche. L’avenir et le web semantique 1. Philippe YONNET. Semantic web | History and Context. As early as the 1980s significant research appeared in information science literature about the development of expert systems for improving search results.Hundreds of universities, start-up companies, and major corporations have published research and filed patents on various algorithmic techniques for machine-aided searching over three decades (and earlier when much of this work was classified as artificial intelligence). By the late 1990s and early 2000s, these technologies began to be described as semantic search components.In 2001 Tim Berners-Lee published an article in Scientific American proposing a semantic web evolving out of the expanding worldwide web.

Quite simply, the vision of semantic search is the availability of software algorithms that would improve retrieval for the average person by interpreting their native inquiry and returning semantically relevant results. The idea is that something as mundane as typing, “where can I find a gas station in Bolton, Mass?” An introduction to Semantic Web and Linked Data.
