Semantic web (05/08/08)

- Semantic Search Arrives at the Web
(source: devX, 18/07/08)
The current generation of search engines is severely limited in its understanding of the user's intent and the web's content. Find out how semantic search can address these limitations.

- A Distributed Process Infrastructure for a Distributed Data Structure (Marko A. Rodriguez)
(source: arXiv, 24/07/08)
The Resource Description Framework (RDF) is continuing to grow outside the bounds of its initial function as a metadata framework and into the domain of general-purpose data modeling. This expansion has been facilitated by the continued increase in the capacity and speed of RDF database repositories known as triple-stores. High-end RDF triple-stores can hold and process on the order of 10 billion triples. In an effort to provide a seamless integration of the data contained in RDF repositories, the Linked Data community is providing specifications for linking RDF data sets into a universal distributed graph that can be traversed by both man and machine. While the seamless integration of RDF data sets is important, at the scale of the data sets that currently exist and will ultimately grow to become, the "download and index" philosophy of the World Wide Web will not so easily map over to the Semantic Web. This essay discusses the importance of adding a distributed RDF process infrastructure to the current distributed RDF data structure.

- Web 3.0 and the Age of Intelligence
(source: Web 2.0 News, 29/07/08)
Often called the Semantic or Pervasive Web, Web 3.0 brings a level of artificial intelligence to transform the Internet from a searchable catalog to a personal guide that can reason in a human-like fashion and provide users with more services and options for social networks. This session will map out the world of Web 3.0, exploring the unique benefits for end users, as well as opportunities for businesses. [...]

Web sémantique: un guide

Semantic Web patterns: a guide to semantic technologies

In this article, we'll analyze the trends and technologies that power the Semantic Web. We'll identify patterns that are beginning to emerge, classify the different trends, and peak into what the future holds.

Le web sémantique dans les faits

Accessible en libre accès, cet article paru en décembre 2007:

Feigenbaum, Lee, Ivan Herman, Tonya Hongsermeier, Eric Neumann, Susie Stephens. "The Semantic Web in Action", Scientific American, vol. 297, Dec. 2007, pp. 90-97.

Corporate applications are well under way, and consumer uses are emerging.
Six years ago in this magazine, Tim Berners-Lee, James Hendler and Ora Lassila unveiled a nascent vision of the Semantic Web: a highly interconnected network of data that could be easily accessed and understood by any desktop or handheld machine. They painted a future of intelligent software agents that would head out on the World Wide Web and automatically book flights and hotels for our trips, update our medical records and give us a single, customized answer to a particular question without our having to search for information or pore through results.

Web sémantique, RDFa et XHTML

RDFa Syntax Last Call Working Draft

The Semantic Web Deployment Working Group and the XHTML 2 Working Group have published the Last Call Working Draft of RDFa in XHTML: Syntax and Processing. RDFa is a specification for attributes to be used with languages such as HTML and XHTML to express structured data. When publishers can express structured data, and when tools can read it, a new world of user functionality becomes available, letting users transfer structured data between applications and web sites, and allowing browsing applications to improve the user experience. For example, a photo's creator, camera setting information, resolution, location and topic can be published as easily as the original photo itself, enabling structured search and sharing. With RDFa, the rendered, hypertext data of XHTML is reused, so that publishers don't need to repeat significant data in the document content.

Le web sémantique expliqué à...

Sur ReadWriteWeb: 11 Things To Know About Semantic Web

1. You don’t need to apologize for calling it Web 3.0. Of course the Web does not upgrade in one go like a company switching to Vista. But there is a definite phase transition from current technologies. My personal Web 3.0 definition is “the combination of Web 2.0 mass collaboration with structured databases”.

2. Semantic Web will start the long, slow decline of relational database technology. Web 3.0 enables the transition from “structure upfront” to “structure on the fly”. The world is clearly too complex to structure upfront, despite the tremendous skills brought by data modelers. Structure on the fly is done by people adding structure as they use the service and by engines that automatically create structure from unstructured content. Structure on the fly is very, very hard and RDBMS is very, very entrenched so this will be a long and slow transition; but the decline is inevitable. Innovation has slowed in the RDBMS world - with open source at one end and Oracle at the other, there is little reason to innovate - just when Semantic Web innovation is accelerating. RDBMS was good for enterprise scale performance and reliability but for Internet scale it falls short; just look at what companies like Amazon use.
