A presentation on semanticweb-the next generationworld wide web. In near future, thedata on the internet wouldnot merely be html files inthe form of documents, itwould be more meaningfulthrough ontology.An extension of the currentWeb that provides an easierway to find, share, reuse andcombine information moreeasily.
