Semantic Web Patterns: A Guide to Semantic Technologies

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. In a recent interview Tim Berners-Lee pointed out that the infrastructure to power the Semantic Web is already here.

Top-Down: A New Approach to the Semantic Web

Earlier this week we wrote about the classic approach to the semantic web and the difficulties with that approach. While the original vision of the layer on top of the current web, which annotates information in a way that is "understandable" by computers, is compelling; there are technical, scientific and business issues that have been difficult to address. One of the technical difficulties that we outlined was the bottom-up nature of the classic semantic web approach. Specifically, each web site needs to annotate information in RDF, OWL, etc. in order for computers to be able to "understand" it.

Dans le développement logiciel, les démarches « Lean » inculquent une culture de l’amélioration continue qui s’articule autour de méthodes et d’outils, parmi lesquels : le kanban, la gestion des flux, le WIP, la taille des lots, la gestion des queues, l’intégration poussée des tests depuis les phases de spécifications, etc. Mais je remarque que, outre les nombreuses vertus de ces démarches, elles peuvent avoir des effets anesthésiants sur le comportement des équipes et peuvent s’avérer néfastes si l’on n’y prend pas garde. Car, à force de travailler à petit pas, à flux tendu et dans une perspective systémique ; à force d’être attentif aux petites corrections et optimisations, on devient aveugle aux aspects environnementaux et architecturaux qui rendent possible cette logique de l’amélioration continue.

Semantic Web W3C's Semantic Web logo The Semantic Web is a collaborative movement led by international standards body the World Wide Web Consortium (W3C).[1] The standard promotes common data formats on the World Wide Web. By encouraging the inclusion of semantic content in web pages, the Semantic Web aims at converting the current web, dominated by unstructured and semi-structured documents into a "web of data". The Semantic Web stack builds on the W3C's Resource Description Framework (RDF).[2] Semantic Web


DBpedia is a crowd-sourced community effort to extract structured information from Wikipedia and make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link the different data sets on the Web to Wikipedia data. We hope that this work will make it easier for the huge amount of information in Wikipedia to be used in some new interesting ways. The Semantic Web is the extension of the World Wide Web that enables people to share content beyond the boundaries of applications and websites. It has been described in rather different ways: as a utopic vision, as a web of data, or merely as a natural paradigm shift in our daily use of the Web. Most of all, the Semantic Web has inspired and engaged many people to create innovative semantic technologies and applications. is the common platform for this community.

The Protégé Ontology Editor and Knowledge Acquisition System

The Protégé Ontology Editor and Knowledge Acquisition System Protégé is a free, open source ontology editor and knowledge-base framework. The Protégé platform supports modeling ontologies via a web client or a desktop client. Protégé ontologies can be developed in a variety of formats including OWL, RDF(S), and XML Schema. Protégé is based on Java, is extensible, and provides a plug-and-play environment that makes it a flexible base for rapid prototyping and application development.
Ontology Tools Survey, Revisited July 14, 2004 A new survey of ontology editors was conducted as a follow-up to an initial survey conducted in 2002. The results of the survey are summarized in this article. The results of the original survey may be found at Ontology Tools Survey, Revisited
