Using Public Data to Fight a War. How does a technology built for apartment-hunting end up being evaluated by the U.S.
Army for use in Afghanistan? Cazoodle is using public data sources like Flickr and OpenStreetMap to build detailed guidebooks for American soldiers. Last week at Strata I sat down with company CTO Govind Kabra to find out how they do it. Its project for the Army is to build a detailed database of information about places in Afghanistan, using only public sources on the Web. The goal is to describe in detail the towns and cities including everything from names, locations and populations, as well as lists and coordinates for schools, mosques, banks and hotels.

Refining UMBEL’s Linking and Mapping Predicates with Wikipedia We are only days away from releasing the first commercial version 1.00 of UMBEL (Upper Mapping and Binding Exchange Layer) .
To recap, UMBEL has two purposes, both aimed to promote the interoperability of Web-accessible content. First, it provides a general vocabulary of classes and predicates for describing domain ontologies and external datasets. Second, UMBEL is a coherent framework of 28,000 broad subjects and topics (the “reference concepts”), which can act as binding nodes for mapping relevant content. The INSEMTIVES ISWC2010 Tutorial - 10 ways to make your semantic app addictive. Co-located with the 9th International Semantic Web Conference (ISWC 2010) 7th November, 2010, Room 3D, Shanghai, China Summary Useful semantic content cannot be created fully automatically, but motivating people to become an active part of this endeavor is still an art more than a science.
In this tutorial we will revisit fundamental design issues of semantic-content authoring technology in order to find out which incentives speak to people to become engaged with the Semantic Web, and to determine the ways they can be transferred into technology design. Meditating on Perl, Python and the Semantic Web. I have been working on a project with the National Labs over the past several months.
A central element of that work has been an effort to bring much of the information and computatiom power of the Labs into a Service Oriented Architecture paradigm and the Semantic Web constructs are at the heart of that part of the work. Not being that familiar with the Semantic Web constructs, I embarked on a concerted effort to teach myself about it. So I have read through several books. But, for me, there is no substitute for doing some actualy programming on a topic to really do a "deep dive" into the material. Web - python semantic proxy/server, wich framework use.

Seth Grimes's Tweet on the Sandro Hawke's video presentation caught my attention.
The presentation, entitled An Introduction to Linked Data, was recorded in June 8, 2010 at the Cambridge Semantic Web Gathering, occurred at Massachusetts Institute of Technology(MIT) in Cambridge, MA. Sandro works at World Wide Web Consortium, an international community where Member organizations, a full-time staff, and the public work together to develop Web standards. From a Summary: "Although the first Semantic Web standards are more than ten years old, only recently have we begun to actually see machines sharing data on the Web. How-to create a Linked Data site.

Présentation du web de données. Use Google Refine to Export JSON. Henry Thompson : Are Uris really names? The Twitter data extraction begins! « Laurens goes semantic… Today I started with the implementation of the extraction package.
The package contains two models: one for the user’s profile and one for the user’s tweets. They then will be annotated in the “Annotator” module and converted into a list of simple triples in the “Triplifier” module. It is being implemented in PHP. There is a very good API: PHP Twiter with OAuth to help with this task. Extraction Package. Featured Tools and Technologies. Encyclopedia and Glossary. Présentation du web de données. Object-Oriented PHP for Beginners. Twice a month, we revisit some of our readers’ favorite posts from through out the history of Nettuts+.
This tutorial was first published in July, 2010. For many PHP programmers, object-oriented programming is a frightening concept, full of complicated syntax and other roadblocks. Recherche à facettes. Un article de Wikipédia, l'encyclopédie libre.
La recherche à facettes (ou recherche facettée, ou navigation à facettes) est une technique en recherche d'information correspondant à une méthodologie d'accès à l'information basée sur une classification à facettes. Elle donne aux utilisateurs les moyens de filtrer une collection de données en choisissant un ou plusieurs critères (les facettes). Il n'est donc pas tant question de recherche que de filtrage (une recherche brute, taxonomique, pouvant être utilisée en complément). Une classification à facettes associe à chaque donnée de l'espace de recherche un certain nombre d'axes explicites de filtrage, par exemple des mots clés issus d'une analyse texte, des métadonnées stockées dans une base de données, etc. On trouve par exemple des recherches à facettes basées sur des catégories sur de nombreux sites de e-commerce.
Tunnel SSH, proxy HTTP [NoJhan - Site perso] Par nojhan le 3 septembre 2008 Quand on utilise des applications réseaux, il peut arriver que l’on soit bloqué par des administrateurs systèmes tatillons (et compétents, donc), qui vont bloquer tous les ports, sauf ceux du web, et faire passer le traffic dans un proxy HTTP.
Dans cet article, je détaille une des (nombreuses) méthodes possible permettant de contourner ce genre de restriction : le tunnel SSH. Configuration Le détail des commandes est donné ici pour Linux, mais la méthode en elle-même, une fois comprise, peut fonctionner pour n’importe-quelle combinaison d’OS. Strata Conference 2011, Day 2 Keynotes. Day 2, and after yesterday’s tutorials the conference is really getting going. Here’s a stream of consciousness from the morning’s keynotes at this sold-out event. “In the same way that the industrial revolution changed what it meant to be human, the data revolution is changing what it means to be alive.” The first of this morning’s keynotes; Hilary Mason from link shortener bit.ly. Data and the people who work with data; “The state of the data union is strong.” The Semantic Link Podcast RSS Feed is live! Episode 2 of The Semantic Link podcast discusses Drupal and more.
Episode 2 of our new Semantic Link podcast went up on SemanticWeb.com this evening, and it’s another good one. Not that I’m biased or anything. The whole team is present once more, and we start the show discussing the implications of Drupal 7 and its newly formalised RDFa-publishing capabilities. Unlike regular semantic technology solutions, which someone has to consciously procure as a Semantic Technology solution, Drupal is first and foremost a (popular, free) Content Management System; the semantic smarts come for free, and therefore reach a massive new audience.
