An RDF programmer would like to work with an extension of KB that includes also the realized semantics that KB is implicitly carrying. To generate this extension, or view, the RDF programmer can define an instance of [ nrl:ViewSpecification ] that computes and returns the procedural semantics for KB . The view specification uses a rule language of choice that provides a number of rules, one of which computes the transitive closure of rdfs:subClassOf , as defined in the RDFS semantics, for a set of RDF triples. Executing the chosen rules over the triples in KB result in a semantic view RDFS(KB) consisting of the RDF triples in KB plus the generated entailment triples. Next, the RDF programmer needs to present some of this extended data to an average user in a simplified way. In particular, the user would at some point like to see the class hierarchy present in RDFS(KB) .

Semantic Technologies Center
Oracle Database 11g Semantic Technologies is an open, standards-based, scalable, secure, reliable and performant RDF management platform. Based on a graph data model, RDF data (triples) are persisted, indexed and queried, like other object-relational data types. Application developers use the power of the Oracle Database 11g to design and develop a wide range of semantic-enhanced business applications in areas that include intelligence, law enforcement, integrated bioinformatics and health care informatics, finance, web social network, and media, games, and content management.
Welcome to OpenRDF.org, the home of Sesame and related applications and developments. Sesame is being used in industries such as pharmaceutical, healthcare and manufacturing for integrating disparate data sources and as a flexible data storage solution. Sesame is used worldwide by some of the worlds largest companies and government agencies. Sesame is a development of Aduna, a company rich in the art of business related search and information integration. If your goal is to open up and integrate your isolated information silos, Sesame and Aduna can help you deliver your project.

Before you start By reading this tutorial you will learn practical details of how to implement a semantic URI scheme, the conceptual structure of the pages of your Web site, and how to apply microformats and RDFa to your markup to add semantic value to your Web pages. The tutorial will focus on certain aspects of Apache configuration and the rendered HTML, rather than the PHP and MySQL itself, so even if you only have a superficial understanding of those two technologies, you can still follow along. About this tutorial This tutorial shows you how to use Semantic Web technologies in the context of a very simple social networking site, SemanticBook (see Prerequisites to access the site). SemanticBook represents your friends by a URI that you can use on any other site, allowing your network of friends to be embedded into a wider network across multiple sites.

Structured Dynamics
Structured Dynamics is an innovative technology and consulting company helping to catalyze the semantic enterprise. Our open semantic framework is the full expression of these innovations. Our services , training , products and ontologies address the challenge of bringing semantic interoperability to the organization. We identify and use the best where it exists; we fill gaps with our own developments and products where it does not.
Welcome to the Bibliographic Ontology Website | The Bibliographi
This is the official Web site for the Bibliographic Ontology, known as BIBO (namespace: bibo ). Here you may find the BIBO specification , examples of its use, links to news and blog postings , projects that are using or extending BIBO, and links to where the community discusses the specification and exchanges information.Fatal error: MyActiveRecord::Connection() - could not connect to database server: 127.0.0.1 in /var/www/vhosts/dotnet/htdocs/classes/MyActiveRecord.class.php on line 127
DOAC: Description of a Career
Description of a Career - Wikipedia, the free encyclopedia
Description Of A Career ( DOAC ) is a semantic vocabulary created by Ramon A. Parada to describe professional capabilities of a worker. It has been designed to be compatible with the European curriculum ( Europass ) so those can be generated from a FOAF+ DOAC file. It includes information about education, working experience, publications, spoken languages and other skills so it can be shared and processed by any application.
This article discusses what you need to know to make your Web site part of the Semantic Web. It starts with a discussion of the problems the Semantic Web tries to solve and then moves to the technologies involved, such as Resource Description Framework (RDF), Web Ontology Language (OWL), and SPARQL Protocol and RDF Query Language (SPARQL). You'll see how the Semantic Web is layered on top of the existing Web. It then covers some issues that you want to know about when you plan a new Web site and also gives specific examples of how to use technologies like RDFa and Microformats to enable your existing Web site to become a part of the Semantic Web. Introduction to the Semantic Web The World Wide Web is the largest single information resource humanity has ever produced.
Planning a Semantic Web site
The Protégé Ontology Editor and Knowledge Acquisition System
Protégé is a free , open source ontology editor and knowledge-base framework. The Protégé platform supports two main ways of modeling ontologies via the Protégé-Frames and Protégé-OWL editors. Protégé ontologies can be exported into a variety of formats including RDF(S), OWL, and XML Schema. (more)Home | Semantic Web Dog Food
Welcome to the Semantic Web Conference Corpus - a.k.a. the Semantic Web Dog Food Corpus ! Here you can browse and search information on papers that were presented, people who attended, and other things that have to do with the main conferences and workshops in the area of Semantic Web research. If you want to learn more on what this site is all about, or how you can have your own conferences and workshops included, you should head over to our FAQ section .FOAF is an RDF spec for describing people and the relationships between them. I thought FOAF had mostly died and been replaced by hcard/XFN. However, it looks like FOAF is going to make a come back as one of the technologies that people build their OpenSocial APIs on top of. So I decided to add it to CrowdVine.
