Semantic Web keywords

• Semantic Web: Semantic Web is a group of methods and technologies to allow machines to understand the meaning - or "semantics" - of information on the "World Wide Web". (wikipedia)
• Ontology: In computer and information science, an ontology is a formal representation of knowledge as a set of concepts within a domain, and the relationships between those concepts. It is used to reason (see reasoning definition)about the entities within that domain, and may be used to describe the domain.(wikipedia)
• Reasoning : Reasoning is the cognitive process of looking for reasons, beliefs, conclusions, actions or feelings. (wikipedia)
• OWL: The Web Ontology Language (OWL) is a family of knowledge representation languages for authoring ontologies. The languages are characterised by formal semantics and RDF/XML-based serializations for the Semantic Web. OWL is endorsed by the World Wide Web Consortium (W3C) and has attracted academic, medical and commercial interest. In October 2007, a new W3C working group was started to extend OWL with several new features as proposed in the OWL 1.1 member submission. This new version, called OWL 2, soon found its way into semantic editors such as Protégé and semantic reasoners such as Pellet,RacerPro, FaCT++ and HermiT. (wikipedia)
