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.
Qu'est-ce que le Web de données, comment le mettre en oeuvre, quelles sont les ressources qui le composent ? Voici seulement quelques-unes des questions soulevées lors de ce "5 à 7" qui s'est déroulé dans les locaux de l'ADBS. A sujet passionnant, intervenante captivante : Emmanuelle Bermès a fait preuve d'une grande pédagogie pour faire le tour de la question pendant près d'une heure et demi.
6 September 2007 : W3C Launches the OWL Working Group . A. OWL is a Web Ontology language.
From 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.
In computer science and information science , an ontology formally represents knowledge as a set of concepts within a domain , and the relationships between pairs of concepts. It can be used to model a domain and support reasoning about entities. In theory, an ontology is a "formal, explicit specification of a shared conceptualisation". [ 1 ] An ontology renders shared vocabulary and taxonomy which models a domain with the definition of objects/concepts, as well as their properties and relations. [ 2 ] Ontologies are the structural frameworks for organizing information and are used in artificial intelligence , the Semantic Web , systems engineering , software engineering , biomedical informatics , library science , enterprise bookmarking , and information architecture as a form of knowledge representation about the world or some part of it. The creation of domain ontologies is also fundamental to the definition and use of an enterprise architecture framework .
