- The document discusses the limitations of Web 2.0 and introduces the concept of Semantic Web or Web 3.0 as a way to address those limitations. - In Semantic Web, everything on the web will have a URI and be represented as subject-predicate-object triples to encode the semantics and meaning of information. - This will allow machines to understand the meaning of web pages and information, leading to benefits like more effective searching and connections between information.
