When we hear about the semantic web there comes many questions in the mind of the user. Some users ask about the web data and its explanation whereas others ask about the contributions of an ordinary web user to this semantic web. Abandon Babel has defined the philosophy behind this semantic web so clearly and easily that any ordinary user can understand that semantic web is “A web of data”. According to W3C and Tim Berners-Lee the amazing world of web is a virtual place for both machines and humans to start off from one database to an

The new public review draft of the document "ebXML Registry Profile for Web Ontology Language (OWL) Version 1.5" has been released. Being produced by the OASIS ebXML Registry Semantic Content Management Subcommittee, it defines a new version of the ebXML profile used for publishing, management, discovery and reuse of the ontologies developed by the OWL Lite standards. This document tries to define the normative ebXML Registry Profile for the OWL (Web Ontology Language) Lite. It has the purpose to normatively specify how the OWL Lite constructs are

The Semantic Web is a new idea that came from the creator of the WWW, URIs, HTTP and HTML. Imagine yourself the information from all over the world being linked as in a global database, in such a way that the information would be easily processable by the machines, on the global scale. This could be the next step in improving the efficiency of representing the data from the Internet. W3C is already working on creating the new Internet standard, as many tools, languages and publications that are focused on semantic web have already been created. But

The OWL is a set of markup languages which are intended for utilization by applications that require processing the data as an alternative of just existing details to humans. Ontology Web language explain the hierarchical association of thoughts in a domain, through this method it can be parsed and implicit by application. OWL has extra services for articulating meaning and semantics than XML, RDF, and RDF-S, and therefore OWL goes outside such languages in its ability to stand for machine interpretable content on the Web. It is part of the

The technology resolves semantic ambiguities in the descriptions of Web service interfaces by combining information retrieval and semantic Web techniques. Information retrieval techniques are used to resolve the domain-independent relationships. For example, in this approach, semantic similarity is derived using an English thesaurus after "tokenization" and part-of-speech tagging of the names of the elements that describe the interfaces of Web services. Semantic Web techniques are used to resolve domain-specific similarities. For example, the

"'A web of data' is a well conducted explanation of the Semantic Web. From the beginning, Tim Berners-Lee and the W3C expected the Web to become a place that allows humans and machines "to start off in one database, and then move through an unending set of databases which are connected not by wires but by being about the same thing." In the Semantic Web, data is annotated with unambiguous definitions and connected by meaningful links. The entire Web thus becomes a network of machine-processable data (including links, which are also data in another

The Semantic Web is a mesh of information linked up in such a way as to be easily processable by machines, on a global scale. You can think of it as being an efficient way of representing data on the World Wide Web, or as a globally linked database.The Semantic Web was thought up by Tim Berners-Lee, inventor of the WWW, URIs, HTTP, and HTML. There is a dedicated team of people at the World Wide Web consortium (W3C) working to improve, extend and standardize the system, and many languages, publications, tools and so on have already been developed.

OASIS announced the publication of a public review draft for the "ebXML Registry Profile for Web Ontology Language (OWL) Version 1.5" specification, ending 11-February-2007. Produced by members of the OASIS ebXML Registry Semantic Content Management Subcommittee, this document defines the ebXML Registry profile for publishing, management, discovery, and reuse of OWL Lite Ontologies. The SC was chartered to define use cases and requirements for managing semantic content within the ebXML Registry 4.0, seeking to establish a formal liaison with relevant

Uche Ogbuji wrote a good article on XML.com here is a summary: "I’m still getting my Weblogger profile here updated, but this year I transitioned from one company I co-founded to another. Zepheira provides data architecture solutions, with a focus on semantic technology. I was early on the Semantic Web bandwagon, and I almost fell off at one point because I felt the useful, modest ideas at the core had been overrun by an academic brand of technological megalomania. This year I felt the timing was right to not only renew my interest in the technology,

Web Ontology Language (OWL) is a markup language for publishing and sharing data using ontologies on the Internet. OWL is a vocabulary extension of the Resource Description Framework (RDF) and is derived from the [[DAML+OIL]] Web Ontology Language (see also DAML and OIL). Together with RDF and other components, these tools make up the Semantic Web project. OWL represents the meanings of terms in vocabularies and the relationships between those terms in a way that is suitable for processing by software. The OWL specification is maintained by the

Introduction Multimedia Web Ontology Language (MOWL) has been designed to facilitate semantic interactions with multimedia contents. It supports perceptual modeling of concepts using expected media properties. While the reasoning in traditional ontology languages, e.g. Web Ontology Language (OWL), is based on Description Logics, MOWL supports a probabilistic reasoning framework based on Bayesian Network. [edit] History W3C forum has undertaken the initiative of standardizing the ontology representation for web-based applications. The Web

Members of the OASIS ebXML Registry Technical Committee have approved a September 2006 Committee Draft version of "ebXML Registry Profile for Web Ontology Language (OWL) Version 1.5" as a new Committee Specification. The document defines the ebXML Registry profile for publishing, management, discovery and reuse of OWL Lite Ontologies. The ebXML Registry holds the metadata for the RegistryObjects and the documents pointed at by the RegistryObjects reside in an ebXML repository. The basic semantic mechanisms of ebXML Registry are classification

Introduction The Resource Description Framework (RDF) - developed by the World-Wide Web Consortium (W3C) - provides the foundation for metadata interoperability across different resource description communities. One of the major obstacles facing the resource description community is the multiplicity of incompatible standards for metadata syntax and schema definition languages. This has lead to the lack of, and low deployment of, cross-discipline applications and services for the resource description communities. RDF provides a solution to these

With more and more Metadata standards or schemas used in various projects, the need of encoding, searching, and exchanging different Metadata sets in one interface becomes much more important. The Resource Description Framework (RDF) is being developed by the World Wide Web Consortium (W3C) to provide an infrastructure for the interoperability of Metadata in a wide range of applications. Every Metadata must define the syntax, semantics, and structure of its elements for its applications. Using XML (eXtensible Markup Language) as its common syntax,

This RDF document currently provides information and references for both the Resource Description Framework (RDF) Model and Syntax Specification and the Resource Description Framework (RDF) Schema Specification. References are given for articles/papers, in addition to RDF software. A more complete RDF reference collection, in many respects, is "Dave Beckett's Resource Description Framework (RDF) Resource Guide." "RDF (Resource Description Framework) is a framework for metadata; it provides interoperability between applications that exchange

The Resource Description Framework (RDF) is a W3C standard for describing resources on the Web. RDF is a framework for describing Web resources, such as the title, author, modification date, content, and copyright information of a Web page. Resource Description Framework (RDF) RDF is the Resource Description Framework proposed by Netscape as an open industry standard for describing how metadata for content is defined in web documents. This metadata is descriptive information about the structure and content of information in a document. This

The members of the METEOR-S project are happy to announce the support for SAWSDL(Semantic Annotations for WSDL) SAWSDL is a simple extension of WSDL using the extensibility elements. It has two basic types of annotations, the model reference and the schema mapping. The model reference annotation, the same as the WSDL-S model reference, is used to associate interfaces/port types, operations, inputs, outputs, and xml schema elements and attributes with Semantic Concepts. Model reference annotations are used by the METEOR-S framework to support the

What is the Semantic Web Challenge? The central idea of the Semantic Web is to extend the current human-readable web by encoding some of the semantics of resources in a machine-processable form. Moving beyond syntax opens the door to more advanced applications and functionality on the Web. Computers will be better able to search, process, integrate and present the content of these resources in a meaningful, intelligent manner. The core technological building blocks are now in place and widely available: ontology languages, flexible storage and

1. Introduction There is a recent tendency in the Semantic Web community to stress the Web aspect of the Semantic Web, meaning that the Semantic Web is increasingly understood as a single, global information space consisting of interlinked RDF data. This tendency is carried by the revival of ideas around interlinking data on the Semantic Web: Current W3C efforts stress the fact that URI references should be dereference-able (W3C working draft on Best Practice Recipes for Publishing RDF Vocabularies). There is a nice memo by Tim Berners-Lee about

The formal specification of knowledge, which is also known as knowledge representation, is not new. Long before the Semantic Web knowledge representation has been part of several studies. Starting in the seventies AI-scientists startet to work on predicate logics for the formal specification of knowledge. Later on knowledge representation with description logics, which are a subtype of predicate logics. Description logics powress is restriced compared to predicate logics but allows efficient reasoning. In 2001 Tim Berners-Lee and others published an

The Future is Here "If [computer networking] were a traditional science, Berners-Lee would win a Nobel Prize,” Eric Schmidt, CEO of Novell, once commented. Indeed, Tim Berners-Lee revolutionized the world when he created the web in 1991. Now, he is talking about the second generation of the web and his talks are generating buzz, the W3C is establishing standards for it, and universities, companies and industry consortiums are building the technologies necessary for it. He refers to it as The Semantic Web. The Semantic Web is envisaged as a place

Identifiers: Uniform Resource Identifier (URI) If I want to discuss something, I must first identify it. How else will you know what I'm referring to? I might do this in an indirect manner: "The North Star." "The strange man at the grocery store." "Those really sour candies that Bob always eats." I might also choose to be more direct: "Polaris." "Jonathan Roberts." "Mega Warheads." To identify items on the Web, we also use identifiers. Because we use a uniform system of identifiers, and because each item identified is considered a "resource," we
