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. The Amazon E-Commerce API - open access to Amazon's catalog We have written here before about Amazon's visionary WebOS strategy. Why has Amazon offered this service completely free? The rise of the API culture The web 2.0 poster child, del.icio.us, is also famous as one of the first companies to open a subset of its web site functionality via an API. Standardized URLs - the API without an API So how do these services get around the fact that there is no API?
How to use a Concept Map to organize and comprehend information Used as a learning and teaching technique, concept mapping visually illustrates the relationships between concepts and ideas. Often represented in circles or boxes, concepts are linked by words and phrases that explain the connection between the ideas, helping students organize and structure their thoughts to further understand information and discover new relationships. Most concept maps represent a hierarchical structure, with the overall, broad concept first with connected sub-topics, more specific concepts, following. Concept Map Example Definition of a Concept Map A concept map is a type of graphic organizer used to help students organize and represent knowledge of a subject. Benefits of Concept Mapping Concept mapping serves several purposes for learners: How to Build a Concept Map Concept maps are typically hierarchical, with the subordinate concepts stemming from the main concept or idea. Start with a main idea, topic, or issue to focus on. Then determine the key concepts
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. That presentation marked the beginning of a year of travel for me. Last week I attended a NYC screening of Tiffany Shlein‘s fantastic new documentary Connected which discusses a “new declaration of interdependence” created by technology. The importance of this connectivity applies to cities, individuals, companies, as well as nations and global causes. We have moved from a siloed, individualistic world to one that is hyperconnected and there is no return. Like this: Like Loading...
60% Of Students Won't Attend A School Without Free WiFi 20 December '11, 07:13pm Follow A recent study by Online Colleges finds that more US college students prefer a hybrid of online/offline education than a pure experience in either direction. This may be a surprise for those that rave about the pros or perils of online classes, but a hybrid learning environment really helps capture the benefits of each. Online universities tend to create a disconnect between students and their school, causing students to miss out on the chance of “bumping elbows” with peers (Cabel Harris, Professor at VCU Brandcenter). Surprisingly, according to research by Educause, only 78% of students feel that wifi is extremely valuable for their academic success, while 60% of students said they wouldn’t attend a college all if it didn’t offer free wifi. As someone with both online and traditional campus experience, this totally resonates with me.
The Next Big Thing is Web 3.0. Catch It If You Can Home | Talis Consulting | World leading expertise in Linked Data and the Semantic Web Forecast 2020: Web 3.0+ and Collective Intelligence « simple processes “We know what we are, but we know not what we may become” – Shakespeare The ancient Chinese curse or saying — “May you live in interesting times.” — is upon us. 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. Past and Present (Web 1.0 and Web 2.0) The best way to explain what Web 2.0 is to compare it to Web 1.0, its earlier version. Afterwards, there was a sudden shift to Web 2.0. Fast Forward to 10 Years from Now (Web 3.0 and beyond) In 10 years, humans and computers will join forces to create “collective intelligence”. Let’s focus on the resulting element — the “collective intelligence”. Please refer to the following diagram where I illustrate how man and machines will achieve such an amazing accomplishment. Obviously this is part thought-experiment and part prophesy. Like this: Like Loading...
3.0 Semantic Web The Semantic Web is a collaborative movement led by international standards body the World Wide Web Consortium (W3C).[1] The standard promotes common data formats on the World Wide Web. By encouraging the inclusion of semantic content in web pages, the Semantic Web aims at converting the current web, dominated by unstructured and semi-structured documents into a "web of data". The Semantic Web stack builds on the W3C's Resource Description Framework (RDF).[2] According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries".[2] The term was coined by Tim Berners-Lee for a web of data that can be processed by machines.[3] While its critics have questioned its feasibility, proponents argue that applications in industry, biology and human sciences research have already proven the validity of the original concept.

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 So how did we arrive at a Web that is less about social and more about you? It's not how much content you consume that is important, it's about what you do with data.
Metadata Metadata is "data about data".[1] 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." [2] Definition[edit] Metadata (metacontent) is defined as the data providing information about one or more aspects of the data, such as: Metadata is data.

Métadonnée Un article de Wikipédia, l'encyclopédie libre. 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. 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). Les bibliothèques numériques ont eu recours aux mêmes dispositifs pour gérer et localiser des documents électroniques. Le terme métadonnée (en anglais : metadata) est apparu dans le cadre de la description de ressources sur Internet dans les années 1990 et s'est ensuite généralisé.
