Linked Data | Linked Data - Connect Distributed Data across the Web The Tabulator (1) Tim Berners-Lee Tim coded up the original version at odd times in November and December 2005. See Links on the Semantic Web from Dec 2005 Undergraduate Research Opportunity Program (UROP) over June-August 2006 people are below. Yushin Chen "Joyce" wrote the calendar views, and incorporated the Simle timeline. Lydia Chilton Lydia is working on statistical analysis, charts, etc. Ruth Dhanaraj Ruth worked on the Tabulator in January 2006, adding the asynchronous fetching of documents during queries, etc. Adam Lerer Adam works on the back-end -- the query system, and generic stuff around the query UI. Jim Hollenbach Jim is responsible for the map view. David Sheets David wrote the RDF parser, and does a lot of architecture and release engineering. Thanks also to Dan Connolly and Ralph Swick for co-supervising students and for ideas, support, testing and encouragement. When you use these techniques on the server, the tabulator works better. pulling in data from the web as you go.
Startup America: A Campaign To Celebrate, Inspire And Accelerate Entrepreneurship Note from the editor: This is a guest post from Aneesh Chopra, United States Chief Technology Officer. During last week’s State of the Union address, President Obama challenged the Nation to out-educate, out-innovate, and out-build our competition to win the future. A critical ingredient in this endeavor is the creative spirit of the American entrepreneur that featured prominently in the President’s Strategy for American Innovation – a framework for long-term economic growth and sustainable job creation. Today, President Obama celebrated the launch of Startup America, a national (public/private) campaign to celebrate, inspire, and accelerate high-growth entrepreneurship across all corners of the country, and the formation of the Startup America Partnership to catalyze private support for entrepreneurial ecosystems. To kick-start the campaign, the Obama Administration announced 27 public and private commitments organized across five key goals: 1. Stay tuned. 2. 3. 4. 5.
How to publish Linked Data on the Web This document provides a tutorial on how to publish Linked Data on the Web. After a general overview of the concept of Linked Data, we describe several practical recipes for publishing information as Linked Data on the Web. This tutorial has been superseeded by the book Linked Data: Evolving the Web into a Global Data Space written by Tom Heath and Christian Bizer. This tutorial was published in 2007 and is still online for historical reasons. The goal of Linked Data is to enable people to share structured data on the Web as easily as they can share documents today. The term Linked Data was coined by Tim Berners-Lee in his Linked Data Web architecture note. Applying both principles leads to the creation of a data commons on the Web, a space where people and organizations can post and consume data about anything. The Web of Data can be accessed using Linked Data browsers, just as the traditional Web of documents is accessed using HTML browsers. Literal Triples RDF Links 3.
YAGO2 - 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%. YAGO is developed jointly with the DBWeb group at Télécom ParisTech University.
Documents numériques et métadonnées A la BnF, la numérisation est considérée depuis l'origine (début des années 1990) comme une technique de reproduction et de conservation à part entière des documents. Les choix de formats, de résolution, de prise de vue reflètent ce principe. La numérisation en mode image continue d’être une priorité car elle permet de proposer aux utilisateurs une reproduction fidèle du document original. Dès lors, la structure et l’organisation du document numérique sont traités selon des méthodes précises afin d’en assurer à la fois la communication et la conservation. Un document numérique est une suite de fichiers sans lien entre eux, décrit par un identifiant unique englobant un ensemble de métadonnées : Métadonnées Une métadonnée est un ensemble structuré d'informations décrivant une ressource quelconque. Le schéma XML refNum décrit les données descriptives et techniques associées au document numérisé. Le schéma comprend 3 grandes parties : METS = Metadat Encoding and Transmission Standard
Tools This page gives an overview of software tools related to the Semantic Web or to semantic technologies in general. Due to the large amount of tools being created in the community, this site is always somewhat outdated. Contributions and updates are welcomed.

63 EdTech Resources You May Have Missed–Treasure Chest, Feb. 6, 2011 Here is this week’s edition of Treasure Chest–63 EdTech Resources You May Have Missed. I know, that’s a lot! What’s funny though is that I thought this week would bring my fewest number of resources. Due to time constraints this week, I didn’t think I was doing a very good job of curating resources. I would also like to thank Larry Ferlazzo for including this blog in his “The Best Blogs…” category. “Tech The Plunge” Is A Blog Worth Reading | Larry Ferlazzo’s Websites of the Day…–Tech The Plunge is an excellent resource-sharing blog written by Jeff Thomas.

Jena Semantic Web Framework Graph | UMBEL The core UMBEL ontology now contains about 26,000 reference concepts organized according to 33 super types. There are more than 60,000 relationships amongst these concepts, resulting in a graph structure of very large size. It is difficult to grasp this graph in the abstract. Thus, using methods earlier described in our use of the Gephi visualization software , we present below a dynamic, navigable rendering of this graph of UMBEL core: Note: at standard resolution, if this graph were to be rendered in actual size, it would be larger than 34 feet by 34 feet square at full zoom !!! This UMBEL graph displays: You may also want to inspect a static version of this big graph by downloading a PDF.
