YAGO - D5: Databases and Information Systems (Max-Planck-Institut für Informatik) Overview YAGO is a huge semantic knowledge base, derived from Wikipedia WordNet and GeoNames.
Currently, YAGO 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.
Web 3.0. A short story about the Semantic Web.
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. 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. Daniel Pfirrmann is Managing Director of DiOmega GmbH, a full service agency for IT and Web services, multimedia applications, mobile applications and web-based training, which he founded in 2006 together with Dominique Bös.

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. In a Single Tweet, as Many Pieces of Metadata as There Are Characters. Reuters To understand big data, look no further than a single tweet.
At 140 characters a tweet seems tiny, but it can yield a wealth of information. According to Elasticsearch, a startup that builds software to help companies mine data from social media, there are 150 separate points of so-called metadata in an individual tweet. Metadata loosely refers to information that can be gleaned about a piece of content.
For example, in legal terms, the body of an email is considered content, while the time stamp, the sender and the receiver are considered metadata. For a tweet, metadata includes a unique numerical ID attached to each tweet, as well as IDs for all the replies, favorites and retweets that it gets. Métadonnée.

Semantic Web: introduction & overview. Reveal.js - The HTML Presentation Framework. Microformats. 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 Neither CommerceNet nor Microformats.org operates as a standards body. Class rel. 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). 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.
The Amazon E-Commerce API - open access to Amazon's catalog. World leading expertise in Linked Data and the Semantic Web. Web 3.0 – Artificial Intelligence? 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 is a collaborative movement led by international standards body the World Wide Web Consortium (W3C). The standard promotes common data formats on the World Wide Web.
Thoughts on Google Plus: The Magic Isn’t Social, It’s Semantic. It’s been said that I’ve called Google Plus “one of the subtlest and most user-friendly ontology development systems we’ve ever seen.” I did, and you can listen for yourselves on the Semantic Link podcast. Why did I do so? Well, G+ follows some of the basic principles of linked data: it uses persistent HTTP URIs for people, Sparks (concepts) and posts.
It allows you to indicate a relationship between to entities and give that relationship a type. It collects, and types, attributes about entities from the expected experts – the entities themselves.
