  2. Presentation outline • Semantics • Meaningful data Representation • Triple Store • Querying & Searching semantic Data • RDF • SPARQL • FOAF (Friend of a Friend) • OWL

  3. Semantics • Semantics is the study of meaning • Sequence of words or symbols used to convey enough meaning

  4. Traditional Data-Modeling methods • Tabulated Data • Relational Data-Model

  5. Tabulated Data • Doctors Near Home

  6. Relational Data-Model

  7. Meaningful data Representation • Triple : Three column Format • A Triple is composed of a subject, predicate and object • Triples could be represented easily in the form of graphs

  8. Triple Babu bought doll Doll costs 20 • Subject : An entity which could be person place or other concrete objects • Predicate: Property of the entity. • Object : could be Subject to other triples or literal value

  9. Merging Triples As the Triples are represented in the form of graphs the merging could be done with less effort
