Aligning Ontologies with Falcon - Home

by night.kame

Falcon-AO, a prominent component of Falcon, is an automatic ontology matching system that helps actualize interoperability between (Semantic) Web applications that use different but related ontologies. Recently, it has become a very practical and popular choice for matching Web ontologies expressed by RDF(S) and OWL. Falcon-AO is implemented in Java, and presently, it is an open source project under the Apache 2.0 license.

MWSAF(METEOR-S Web Service Annotation Framework) is a semantic web based graphical tool that enables you to annotate existing Web service descriptions with Ontologies. It facilitates the parsing of WSDL files and Ontologies. This enables the user to annotate Web service descriptions semi-automatically.

D2RQ - Treating Non-RDF Databases as Virtual RDF Graphs - Chris Bizer

by parmentierf (via)
D2RQ is a declarative language to describe mappings between relational database schemata and OWL/RDFS ontologies. The D2RQ Platform uses these mapping to enables applications to access a RDF-view on a non-RDF database through the Jena and Sesame APIs, as well as over the Web via the SPARQL Protocol and as Linked Data.

Le moteur d’inférence qui va rajouter des nouvelles informations à partir des informations existantes est le composant pour lequel il n’y a pas d’équivalent dans le monde SGBD (1); c’est lui qui vient donner tout son sens au reste de la pyramide des technos (XML, URI, RDF, OWL), en interprétant et “motorisant” une ontologie.

Introduction to Semantic Web Vision and Technologies - Part 4 - Protege 101 (Screencast) - Blog - Semantic Focus

by parmentierf
Today, we present a screencast exhibiting Protégé — a free, open source ontology editor and knowledge-base framework developed by Stanford Center for Biomedical Informatics Research at the Stanford University School of Medicine. In this screencast, we show you how to develop a useful Semantic Web-ready application in just minutes. You will learn how to model a very simple ontology in OWL (the Web Ontology Language).

Image Annotation on the Semantic Web

by benoit

Many applications that process multimedia assets make use of some form of metadata that describe the multimedia content. The goals of this document are to explain the advantages of using Semantic Web languages and technologies for the creation, storage, manipulation, interchange and processing of image metadata. In addition, it provides guidelines for Semantic Web-based image annotation, illustrated by use cases. Relevant RDF and OWL vocabularies are discussed, along with a short overview of publicly available tools.

HTTP and resource identity

by CharlesNepote
"[...] It seems that folks like Yahoo! and Twittervision offer different representations of the same resource using different URIs .xml, .json, .php, .yaml, etc. I’d say that’s arisen because users have little control over content-negotiation in their browser. Isn’t having the same resource identified by lots of different URIs an issue for the Semantic Web? [...]"
