WSMO
WSMO or Web Service Modeling Ontology is a conceptual model for relevant aspects related to Semantic Web Services. It provides an ontology based framework, which supports the deployment and interoperability of Semantic Web Services. The WSMO has four main components: * Goals - The client's objectives when consulting a Web Service. * Ontologies - A formal Semantic description of the information used by all other components. * Mediators - Connectors between componentes with mediation facilities. Provides interoperability between different ontologies. * WebServices - Semantic description of Web Services. May include functional (Capability) and usage (Interface) descriptions. The WSMO working group, part of the ESSI Cluster aligns the research and development efforts in the areas of Semantic Web Services between several European FP6 research projects. WSMO working group includes the WSML working group, which aims at developing a language called Web Services Modeling Language WSML ...

Web Services Modeling Language
WSML or Web Service Modeling Language is a formal language that provides a syntax and semantics for the Web Service Modeling Ontology (WSMO). In other words, the WSML provides means to formally describe the WSMO elements as Ontologies, Semantic Web services, Goals, and Mediators. The WSML is based on the logical formalisms as Description Logic, First-order Logic and Logic Programming.J. de Bruijn, H. Lausen, A. Polleres, D. Fensel: The WSML rule languages for the Semantic Web. W3C Workshop on Rule Languages for Interoperability, Washington USA, 27–28 April 2005. http://dip.semanticweb.org/TheWSMLrulelanguagesfortheSemanticWeb.htm Language variants of WSML * ''WSML Core'', defined as an intersection of the Description Logic and Horn Logic. Supports modeling classes, attributes, binary relations and instances. * ''WSML-DL'', extension of the WSML Core, fully captures the Description Logic \mathcal^\mathcal. * ''WSML-Flight'', extension of the WSML Core, provides feature ...

Semantic Web Services
A semantic web service, like conventional web services, is the server end of a client–server system for machine-to-machine interaction via the World Wide Web. Semantic services are a component of the semantic web because they use markup which makes data machine-readable in a detailed and sophisticated way (as compared with human-readable HTML which is usually not easily "understood" by computer programs). The problem addressed by Semantic Web Services The mainstream XML standards for interoperation of web services specify only syntactic interoperability, not the semantic meaning of messages. For example, Web Services Description Language (WSDL) can specify the operations available through a web service and the structure of data sent and received but cannot specify semantic meaning of the data or semantic constraints on the data. This requires programmers to reach specific agreements on the interaction of web services and makes automatic web service composition difficult. Semant ...

Ontology (information Science)
In information science, an ontology encompasses a representation, formal naming, and definitions of the categories, properties, and relations between the concepts, data, or entities that pertain to one, many, or all domains of discourse. More simply, an ontology is a way of showing the properties of a subject area and how they are related, by defining a set of terms and relational expressions that represent the entities in that subject area. The field which studies ontologies so conceived is sometimes referred to as ''applied ontology''. Every academic discipline or field, in creating its terminology, thereby lays the groundwork for an ontology. Each uses ontological assumptions to frame explicit theories, research and applications. Improved ontologies may improve problem solving within that domain, interoperability of data systems, and discoverability of data. Translating research papers within every field is a problem made easier when experts from different countries mainta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Services
A web service (WS) is either: * a service offered by an electronic device to another electronic device, communicating with each other via the Internet, or * a server running on a computer device, listening for requests at a particular port over a network, serving web documents (HTML, JSON, XML, images). In a web service, a web technology such as HTTP is used for transferring machine-readable file formats such as XMLHttpRequest, XML and JSON. In practice, a web service commonly provides an Object database, object-oriented web-based interface to a database server, utilized for example by another web server, or by a Mobile app development, mobile app, that provides a user interface to the end-user. Many organizations that provide data in formatted HTML pages will also provide that data on their server as XML or JSON, often through a Web service to allow Web syndication, syndication. Another application offered to the end-user may be a Mashup (web application hybrid), mashup, where a W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
