Search Results for "semantics"

As the technology is changing day by day there have been many changes in the web servers, especially the technology is trying to find out the ambiguities in the semantics, to resolve the domain independent relationships informational retrieval technologies are used web techniques of the semantics are used to resolve domain-specific similarities the relationships among the concepts are modeled as domain ontology semantic annotations are annotated in the web services from domain ontologies. The ontological similarity of the semantic annotations

The terms used to represent and describe an area of knowledge is called as ontology. For applications that need to merge information from or search across diverse communities ontologies are critical. Although DTDs , XML and XML Schemas are enough for exchanging  data between parties who have beforehand agreed to the definitions. Due to their lack of semantics the machines deny performing this task with new XML vocabularies. The vision for the future of the web is Semantic web in which explicit meaning is given to information, making

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 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

A markup language named Web Ontology Language (OWL) used to publish and share data with ontology’s on internet. It’s a language expansion of resources description framework and resultant from DAML including Oil. Jointly with resources description framework and additional parts, these tools structure the Semantic net project. OWL symbolizes the senses of types in vocabularies or language and the relations among those conditions in a way that is appropriate for dispensation by software. OWL conditions are retained by the World Wide

The World Wide Web Consortium (W3C) issued Web Ontology Language (OWL) as a W3C Candidate Recommendation. Candidate Recommendation is an explicit call for implementations, indicating that the document has been reviewed by all other W3C Working Groups, that the specification is stable, and appropriate for implementation.OWL is a language for defining structured, Web-based ontologies which enable richer integration and interoperability of data across application boundaries. Early adopters of these standards include bioinformatics and medical communities,

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

An ontology defines the terms used to describe and represent an area of knowledge. Ontologies are critical for applications that need to search across or merge information from diverse communities. Although XML DTDs and XML Schemas are sufficient for exchanging data between parties who have agreed to the definitions beforehand, their lack of semantics prevents machines from reliably performing this task with new XML vocabularies. The Semantic Web is a vision for the future of the Web in which information is given explicit meaning, making it easier

Annotation is the process of associating metadata with data. This article presents a Web services API intended as an industry standard for client-server systems designed to facilitate the structured annotation of heterogeneous data. The author presents the goals of the Annotation Web services API and then discusses how those goals motivate the data model around which the API operates. The author also discusses 29 methods that comprise the API including two examples of possible sequences of API calls to create and retrieve annotations. The Annotation

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

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

An ontology defines the terms used to describe and represent an area of knowledge. Ontologies are critical for applications that need to search across or merge information from diverse communities.

Abstract As the semantic web grows, there is the need for more and more formal ontology definitions in standard languages such as the Web Ontology Language (OWL) of the World Wide Web Consortium. With that said, there are numerous projects that predate OWL that can serve as useful foundations. One such project is bibTeX, a method of marking up bibliographic data, primarily for use in LaTeX documents, but also useful for generic bibliographic storage. This document describes bibTeX recast in OWL for use in RDF applications. Status of this

The Ontology Web Language (OWL) is a set of markup languages which are designed for use by applications that need to process the content of information instead of just presenting information to humans. OWL ontologies describe the hierarchical organization of ideas in a domain, in a way that can be parsed and understood by software. OWL has more facilities for expressing meaning and semantics than XML, RDF, and RDF-S, and thus OWL goes beyond these languages in its ability to represent machine interpretable content on the Web. OWL is part of the W3C

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

The future of Web languages seems to be the Semantic Web, and OWL is one of its activities. Now a question arises: What does OWL provide that XML and XML Schema don't? The answer is outlined below. 1. XML provides a syntax for structured documents, but doesn't define semantic constraints on the meaning of the documents. 2. XML Schema is a language for restricting the structure of XML documents. 3. RDF is a data model for objects ("resources") and relations between them; it provides simple semantics for this data model, and these data models can be

Features of RDF In general, RDF provides the basis for generic tools for authoring, manipulating, and searching machine understandable data on the Web thereby promoting the transformation of the Web into a machine-processable repository of information. RDF provides the following features: - interoperability of metadata - machine understandable semantics for metadata - better precision in resource discovery than full text search - future-proofing applications as schemas evolve Further development will enable RDF to also provide: - a uniform

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,

Abstract The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. This Primer is designed to provide the reader with the basic knowledge required to effectively use RDF. It introduces the basic concepts of RDF and describes its XML syntax. It describes how to define RDF vocabularies using the RDF Vocabulary Description Language, and gives an overview of some deployed RDF applications. It also describes the content and purpose of other RDF specification documents. Status of this

GILS subset of the Basic Semantics Register (with stylesheet) This RDF schema contains GILS schema elements as registered in the ISO Basic Semantics Register (BSR). It defines a hierarchy of RDF Classes rooted to the BSR concept "InformationResource" (RDF Classes are roughly equivalent to BSR Semantic Components). The RDF schema also defines for each GILS element an RDF Property (RDF Properties are roughly equivalent to BSR Semantic Units). English tags in SGML/XML (with stylesheet) This RDF schema has SGML/XML element tags in English, expressed as

[February 10, 2004] W3C Recommendations: Resource Description Framework (RDF) and Web Ontology Language (OWL). The World Wide Web Consortium has announced "final approval of two key Semantic Web technologies, the revised Resource Description Framework (RDF) and the Web Ontology Language (OWL). RDF and OWL are Semantic Web standards that provide a framework for asset management, enterprise integration and the sharing and reuse of data on the Web. These standard formats for data sharing span application, enterprise, and community boundaries, since

As the set of available Web Services expands, it becomes increasingly important to have automated tools to help identify services that match a requester's requirements. Finding suitable Web services depends on the facilities available for service providers to describe the capabilities of their services and for service requesters to describe their requirements in an unambiguous and ideally, machine-interpretable form. Adding semantics to represent the requirements and capabilities of Web services is essential for achieving this unambiguity and

We recommend that certain principles guide any work to define a framework for Web services semantics. Our work is guided by the following principles. ? Build on existing Web Services standards: The Web services standards are fast becoming a preferred technology for application integration because of the promise of their interoperability. Companies are making investments in integration projects based on Web Services. Therefore, we believe that any approach to adding semantics to Web Services should be specified in an upwardly compatible

Introduction The Web Services Description Language (WSDL) specifies a way to describe the abstract functionalities of a service and concretely how and where to invoke it. The WSDL 2.0 specification does not include semantics in the description of Web services. Therefore, two services can have similar descriptions while meaning totally different things. Resolving this ambiguity in Web services descriptions is an important step toward automating the discovery and composition of Web services — a key productivity enabler in many domains including

Abstract This document defines a set of extension attributes for the Web Services Description Language and XML Schema definition language that allows description of additional semantics of WSDL components. The specification defines how semantic annotation is accomplished using references to semantic models, e.g. ontologies. Semantic Annotations for WSDL and XML Schema (SAWSDL) does not specify a language for representing the semantic models. Instead it provides mechanisms by which concepts from the semantic models, typically defined outside the WSDL

Semantic Tools for Web Services are semantics-based, semi-automatic Eclipse plug-ins for Web service matching, discovery, and composition. Software developers can use these tools to find and compose existing software (represented as Web services) in order to implement new or changed business processes. Internet technology (IT) consultants and developers can use them to integrate new or legacy business applications that are represented as Web services. The tools are now available as an Eclipse plug-in that can be installed on IBM's WebSphere®

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

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
