Why we need the semantic web

People understand…

Machines don’t…

The semantic web helps machines to help people to understand the web

So how do we add meaning for machines?

Linked data

“ Linked data is the Semantic Web done right, and the web done right” Sir Tim Berners-Lee said that

“ Magazines are made of pages, the web is made of links” I said that
