Tabula Rasa : In computer science, tabula rasa refers to the development of autonomous agents which are provided with a mechanism to reason and plan toward their goal, but no "built-in" knowledge-base of their environment.
“ A semantic web has yet to emerge , but when it does, the day to day mechanism of trade, bureaucracy and our daily lives will be handled by machines talking to machines. The intelligent agents people have touted for ages will finally materialize .”

Semantic Web Ontology : In computer science and information science, an ontology is a formal representation of the knowledge by a set of concepts within a domain and the relationships between those concepts. It is used to reason about the properties of that domain, and may be used to describe the domain. In theory, an ontology is a "formal, explicit specification of a shared conceptualisation".
Semantic Web RDF : It is a family of World Wide Web Consortium (W3C) specifications originally designed as a metadata data model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax formats.
Semantic Web OWL(Web Ontology Language) : It is a family of knowledge representation languages for authoring ontologies endorsed by the World Wide Web Consortium.They are characterised by formal semantics and RDF/XML-based serializations for the Semantic Web. OWL has attracted both academic, medical and commercial interest.
Semantic Web SPARQL(SPARQL Protocol and RDF Query Language) : It is an RDF query language. It was standardized by the RDF Data Access Working Group (DAWG) of the World Wide Web Consortium, and is considered a key semantic web technology. On 15 January 2008, SPARQL became an official W3C Recommendation.
Semantic Web FOAF(Friend Of A Friend) : It is a machine-readable ontology describing persons, their activities and their relations to other people and objects. Anyone can use FOAF to describe him or herself. FOAF allows groups of people to describe social networks without the need for a centralised database.
Semantic Web RDFa (or Resource Description Framework – in – attributes) : It is a W3C Recommendation that adds a set of attribute level extensions to XHTML for embedding rich metadata within Web documents.
Semantic Web A microformat (sometimes abbreviated μF) is a web-based approach to semantic markup that seeks to re-use existing HTML/XHTML tags to convey metadata and other attributes, in web pages and other contexts that support (X)HTML, such as RSS.
Semantic Web DBpedia is a project aiming to extract structured information from the information created as part of the Wikipedia project. This structured information is then made available on the World Wide Web. DBpedia allows users to query relationships and properties associated with Wikipedia resources, including links to other related datasets. DBpedia has been described by Tim Berners-Lee as one of the more famous parts of the Linked Data project.
