Semantic Web


DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia and to link other datasets on the Web to Wikipedia data.

W3C Semantic Web Logos and Policies

The three sides of the tri-color cube in these logos evoke the triplet of the RDF model. The peeled back lid invites you to Open Your Data to the Semantic Web!


Semantic Annotations for WSDL

W3C Working Draft 30 June 2006. This document describes a set of extension attributes for the Web Services Description Language Version 2.0 (WSDL 2.0) [WSDL 2.0] that describes the semantics of WSDL 2.0 components. The specification defines how such semantic annotation is accomplished using references to semantic models, e.g. ontologies, defined outside the WSDL 2.0 document.


Why the World is ready for the Semantic Web

Some people argue that although the Semantic Web technologies are all in place, the world isn’t ready for the Semantic Web vision yet; that we’re still a couple of years away from fully embracing and adopting Semantic Web principles and attitudes. Perhaps, though, the opposite is closer to the truth: that some of the biggest and best projects on the web today are based on Semantic Web principles - they just don’t happen to be using Semantic Web technologies.



OASIS Technical Committees - UBL Naming and Design Rules

The purpose of the NDR SC is to recommend to the TC rules and guidelines for normative-form schema design, instance design, and markup naming, and write and maintain documentation of these rules and guidelines.


Semantic Web Architecture: Stack or Two Towers?

Horrocks et al discuss language architecture for the Semantic Web, and in particular different proposals for extending this architecture with a rules component. They argue that an architecture that maximises compatibility with existing languages, in particular RDF and OWL, will benefit the development of the Semantic Web, and still allow for forms of closed world assumption and negation as failure.

XML Resource Directory Description Language (RDDL)

This document is the official spec for the Resource Directory Description Language (RDDL). A RDDL document, called a Resource Directory, provides a package of information about some target, including human-readable descriptive material about the target, and a directory of individual resources related to the target, each directory entry containing descriptive material and linked to the resource in question.


Semantic Web to be Berners-Lee's second success?

WWW10 report from xmlhack: With the Semantic Web, Tim Berners-Lee is attempting to reproduce the technique that worked so well with the Web -- a simple concept magnified by billion of distributed sites. However, more effort will be needed to convince the skeptics.
