Overview YAGO2s is a huge semantic knowledge base, derived from Wikipedia WordNet and GeoNames.
Currently, YAGO2s has knowledge of more than 10 million entities (like persons, organizations, cities, etc.) and contains more than 120 million facts about these entities. YAGO is special in several ways: The accuracy of YAGO has been manually evaluated, proving a confirmed accuracy of 95%. Every relation is annotated with its confidence value.YAGO combines the clean taxonomy of WordNet with the richness of the Wikipedia category system, assigning the entities to more than 350,000 classes.YAGO is an ontology that is anchored in time and space.

We are in the midst of a new revolution fueled by advancements in the Internet and technology. Currently, there is an abundance of information and the size of social interaction has reached a colossal scale. Within a span of just one generation, the availability of information and our access to them has changed dramatically from scarcity to surplus. Web 3.0+: The Hyperconnected Global Internet « Nothing Ventured… The title of this blog comes from a presentation I did at last year’s Web 2.0 conference in NYC, in September 2010.
I overviewed the growth of the global internet and penetration, noting that the future of the Web was going to be driven by emerging countries, as mobile connectivity continues to be more ubiquitous and the West is largely penetrated. The slides are here. While I haven’t updated the numbers, if anything, the pace of adoption has accelerated. We also have the experience of the Arab Spring, Japan earthquake and, more recently, Occupy Wall Street in the past year to highlight how global the Web has become.
Some Internet experts believe the next generation of the Web - Web 3.0 - will make tasks like your search for movies and food faster and easier. Instead of multiple searches, you might type a complex sentence or two in your Web 3.0 browser, and the Web will do the rest. For example, you could type "I want to see a funny movie and then eat at a good Mexican restaurant. What are my options? " The Web 3.0 browser will analyze your response, search the Internet for all possible answers, and then organize the results for you. Web 3.0: "Semantic Web" – navigating in an ocean of data. Even before the interactive "Web 2.0" was established with its social networks such as Facebook and Twitter, ways had been conceived of making semantic links, in other words meaningful connections, visible in a "Web 3.0".
But despite some promising attempts, fifteen years later the "Semantic Web" is still waiting for a breakthrough. The Alumniportal talks about this to Daniel Pfirrmann. The Next Big Thing is Web 3.0.

Ontologie (informatique) Un article de Wikipédia, l'encyclopédie libre.
Par analogie, le terme est repris en informatique et en science de l'information, où une ontologie est l'ensemble structuré des termes et concepts représentant le sens d'un champ d'informations, que ce soit par les métadonnées d'un espace de noms, ou les éléments d'un domaine de connaissances. L'ontologie constitue en soi un modèle de données représentatif d'un ensemble de concepts dans un domaine, ainsi que des relations entre ces concepts.
Elle est employée pour raisonner à propos des objets du domaine concerné. Plus simplement, on peut aussi dire que l' « ontologie est aux données ce que la grammaire est au langage ». L'objectif premier d'une ontologie est de modéliser un ensemble de connaissances dans un domaine donné, qui peut être réel ou imaginaire.
Metadata. Metadata is "data about data". There are two "metadata types;" structural metadata, about the design and specification of data structures or "data about the containers of data"; and descriptive metadata about individual instances of application data or the data content.
The main purpose of metadata is to facilitate in the discovery of relevant information, more often classified as resource discovery. Metadata also helps organize electronic resources, provide digital identification, and helps support archiving and preservation of the resource. Metadata assists in resource discovery by "allowing resources to be found by relevant criteria, identifying resources, bringing similar resources together, distinguishing dissimilar resources, and giving location information.
"  Definition Metadata (metacontent) is defined as the data providing information about one or more aspects of the data, such as: Home - Common Tag. Infobox. An infobox may be implemented in another document by transcluding it into that document and specifying some or all of the attribute–value pairs associated with that infobox, known as parameterization.
Wikipedia Baeza-Yates and King say that some editors find templates such as infoboxes complicated, as the template may hide text about a property or resource that the editor wishes to change; this is exacerbated by chained templates, that is templates transcluded within other templates. As of August 2009, English Wikipedia used about 3,000 infobox templates that collectively used more than 20,000 attributes.
Since then, many have been merged, to reduce redundancy. As of June 2013, there were at least 1,345,446 transclusions of the parent Infobox template, used by some, but not all, infoboxes, on 4,251,127 articles. Machine learning About 44.2% of Wikipedia articles contained an infobox in 2008, and about 33% in 2010. Notes In a Single Tweet, as Many Pieces of Metadata as There Are Characters. Métadonnée.

Un exemple type est d'associer à une donnée la date à laquelle elle a été produite ou enregistrée, ou à une photo les coordonnées GPS du lieu où elle a été prise. Historique[modifier | modifier le code] Tous les établissements qui ont à gérer de l'information, bibliothèques, archives ou médiathèques ont déjà une longue pratique dans la codification du signalement ou des contenus des documents qu'ils manipulent.
Avant l'arrivée de l'informatique on utilisait des fiches cartonnées dont la structure a été normalisée en 1954 sous la référence ISBD (International standard bibliographic description). Ces descriptions ont ensuite été informatisées sous la forme de notices bibliographiques et normalisées (voir par exemple les formats MARC en 1964 utilisant la norme ISO 2709 dont la conception a démarré en 1960).

Optimus—Microformats Transformer. What is it? Optimus—is a microformats transformer. Easily transform your microformatted content to nice, clean, easily digestible, XML, JSON or JSON-P. Microformat. A microformat (sometimes abbreviated μF) is a web-based approach to semantic markup which seeks to re-use existing HTML/XHTML tags to convey metadata and other attributes in web pages and other contexts that support (X)HTML such as RSS. This approach allows software to process information intended for end-users (such as contact information, geographic coordinates, calendar events, and similar information) automatically. Although the content of web pages is technically already capable of "automated processing", and has been since the inception of the web, such processing is difficult because the traditional markup tags used to display information on the web do not describe what the information means. Microformats can bridge this gap by attaching semantics, and thereby obviate other, more complicated, methods of automated processing, such as natural language processing or screen scraping.
Background Home - schema.org. GetSchema. Schema Creator. Beyond Social: Read/Write in The Era of Internet of Things. This blog was founded in 2003 on the philosophy of a read/write Web - a Web in which people can create content as easily as they consume it. This trend eventually came to be known as Web 2.0 - although others preferred Social Web - and was popularized by activities like blogging and social networking. It would be easy to say that the 'social' element is still the primary part of today's Web, since the popular products of this era enable you to say what's on your mind (Facebook), what's happening (Twitter), or where you are (Foursquare).
All of these are mostly social activities. But more significantly, these and other products output data that will increasingly be used to build personalized services for you. The more data there is, the better Web services will be at delivering personal value to you. How We Went Beyond Social. Web 3.0: When Web Sites Become Web Services. Today's Web has terabytes of information available to humans, but hidden from computers. It is a paradox that information is stuck inside HTML pages, formatted in esoteric ways that are difficult for machines to process. The so called Web 3.0, which is likely to be a pre-cursor of the real semantic web, is going to change this. What we mean by 'Web 3.0' is that major web sites are going to be transformed into web services - and will effectively expose their information to the world. The transformation will happen in one of two ways. Some web sites will follow the example of Amazon, del.icio.us and Flickr and will offer their information via a REST API.

Representing the Digital Enterprise Research Institute, Liam Ó Móráin , recently discussed the work of the DERI on the Semantic Web and the move from Web 2.0 to Web 3.0. Liam explains how the evolution of Web 2.0 to Web 3.0 (also known as Semantic Web) is taking the web experience to the user in a new and more powerful way. Web 3.0 will quickly and easily combine information from very diverse sources and serve the information to the user, based on intelligent browsing. It is due to the power of the Semantic Web that Google and other search applications serve up, not just what you search for but also related links which are specific to your search history, demographic area and personal browsing preferences.
Google and other sites, such as Amazon are able to serve user-specific content within seconds, using the powerful, artificially intelligent brain of Web 3.0.

The Semantic Web, Syllogism, and Worldview. The Semantic Web, Syllogism, and Worldview First published November 7, 2003 on the "Networks, Economics, and Culture" mailing list. Subscribe to the mailing list. The W3C's Semantic Web project has been described in many ways over the last few years: an extension of the current web in which information is given well-defined meaning, a place where machines can analyze all the data on the Web, even a Web in which machine reasoning will be ubiquitous and devastatingly powerful.
The problem with descriptions this general, however, is that they don't answer the obvious question: What is the Semantic Web good for? Collective intelligence: an interview with Pierre Levy. About Eelke Hermens Hacker and cultural critic, passionate about information theory and semantics. Fed up with cyber utopians. In a previous post I discussed and, hopefully, debunked some common assumptions on the next phase of the World Wide Web, or web 3.0. The general assumption is that in the 2.0 era the user was at the centre, the produser took control and the cult of the amateur was born. 3.0 Semantic Web.
