The Semantic Web: An Introduction

This document is designed as being a simple but comprehensive introductory publication for anybody trying to get into the Semantic Web: from beginners through to long time hackers. Recommended pre-reading: the Semantic Web in Breadth. Table Of Contents What Is The Semantic Web? The Semantic Web is a mesh of information linked up in such a way as to be easily processable by machines, on a global scale. You can think of it as being an efficient way of representing data on the World Wide Web, or as a globally linked database. The Semantic Web was thought up by Tim Berners-Lee, inventor of the WWW, URIs, HTTP, and HTML. What's the rationale for such a system? So the Semantic Web can be seen as a huge engineering solution... but it is more than that. URI - Uniform Resource Identifier A URI is simply a Web identifier: like the strings starting with "http:" or "ftp:" that you often find on the World Wide Web. RDF - Resource Description Framework A triple can simply be described as three URIs. Logic

RDF - Semantic Web Standards Overview RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications. This linking structure forms a directed, labeled graph, where the edges represent the named link between two resources, represented by the graph nodes. Recommended Reading The RDF 1.1 specification consists of a suite of W3C Recommendations and Working Group Notes, published in 2014. A number of textbooks have been published on RDF and on Semantic Web in general. Discussions on a possible next version of RDF

Semantic Web The promise of web standards W3C standards define an open web platform for application development. The web has the unprecedented potential to enable developers to build rich interactive experiences, that can be available on any device. The platform continues to expand, but web users have long ago rallied around HTML as the cornerstone of the web. W3C Standards and Drafts Why W3C web standards? W3C publishes recommendations, that are considered web standards. W3C develops technical specifications according to the W3C Process, which is designed to maximize consensus, ensure quality, earn endorsement and adoption by W3C Members and the broader community. W3C web standards are optimized for interoperability, security, privacy, web accessibility, and internationalization. W3C's proven web standards process is based on fairness, openness, royalty-free, we make the web work, for everyone. Wide array of applications W3C standards, technical specifications and guidelines are widely deployed on the web:

The US sub-prime crisis The US sub-prime mortgage crisis has led to plunging property prices, a slowdown in the US economy, and billions in losses by banks. It stems from a fundamental change in the way mortgages are funded. Traditionally, banks have financed their mortgage lending through the deposits they receive from their customers. This has limited the amount of mortgage lending they could do. In recent years, banks have moved to a new model where they sell on the mortgages to the bond markets. This has made it much easier to fund additional borrowing, But it has also led to abuses as banks no longer have the incentive to check carefully the mortgages they issue. In the past five years, the private sector has dramatically expanded its role in the mortgage bond market, which had previously been dominated by government-sponsored agencies like Freddie Mac. They also included "jumbo" mortgages for properties over Freddie Mac's $417,000 (£202,000) mortgage limit. But no one is sure how long the slowdown will last.

Greasy Fork - scripts de usuario útiles y seguros C Semantic Web Activity The Semantic Web is a web of data. There is lots of data we all use every day, and it is not part of the web. I can see my bank statements on the web, and my photographs, and I can see my appointments in a calendar. But can I see my photos in a calendar to see what I was doing when I took them? Why not? The Semantic Web is about two things. See also the activity news for an account of recent events, publications, etc. The following groups are part of the Semantic Web Activity. Active Groups Semantic Web Coordination Group The Semantic Web Coordination Group is tasked to provide a forum for managing the interrelationships and interdependencies among groups focusing on standards and technologies that relate to this goals of the Semantic Web Activity. RDFa Working Group The mission of the RDFa Working Group, formerly known as the W3C RDF Web Application Working Group, is to support the developing use of RDFa for embedding structured data in Web documents in general.

Hindu Articles Las relaciones familiares de todas las lenguas de Europa, explicadas en este brillante mapa Europa es un crisol de lenguas: un vivero que comienza en Tarifa y termina en el Ártico a través del cual conviven y se relacionan entre sí un centenar de lenguas de la más variopinta procedencia. Hay de todo, desde herencias deformadas y antiquísimas del latín hasta monstruos deformes que han terminado dominando el mundo, pasando por idiomas arcanos e ignotos y lenguas que provienen más allá del muro. Si no eres lingüista, hacerse una idea de cómo se relacionan entre sí y de dónde provienen las principales lenguas (y las más pequeñitas) puede convertirse en un quebradero de cabeza. El último y más espectacular con el que nos hemos topado es este realizado por Alternative Transport, un divertido blog anglosajón que atraviesa algunas de nuestras pequeñas obsesiones (transporte, mapas, idiomas, etcétera). El objetivo del mapa es ilustrar cómo de cerca o de lejos están los idiomas entre sí. Las urálicas, incluyendo la lengua húngara, ugria. Las lenguas celtas. Restan los pesos pesados.

WhatsApp Ghost, usa WhatsApp sin que se refleje tu última conexión (Android) A pesar de las muchas quejas sobre su seguridad, WhatsApp sigue siendo el cliente de mensajería móvil más popular y empleado por usuarios de todo el mundo. Otra de las características de esta aplicación que no gusta a bastantes de sus usuarios es que se refleje la última conexión, es decir la última vez que abrimos el programa y participamos de WhatsApp. Si formas parte de este segundo grupo, de los que están molestos con que WhatsApp muestre la última vez que se conectaron, puedes evitarlo con la ayuda de una aplicación llamada WhatsApp Ghost. Se trata de una app gratuita para Android que no incluye publicidad, mejor que mejor. El primer paso, como es obvio, es instalarla, después deberás recordar pulsar sobre el icono de WhatsApp Ghost antes de abrir WhatsApp. Si recuerdas este sencillo paso no se reflejará tu conexión, podrás leer todos los mensajes e incluso contestarlos para que se envíen al cerrar WhatsApp Ghost.
