It's not yet here, but Web 3.0 is expected to bring Semantic Web capabilities. Advanced as Web 2.0 applications may seem, they all rely mostly on structured information. We use the same concept of searching for keywords and matching these keywords with web content without much understanding of context, content and intention of user's request. Also called Web of Data, Web 3.0 will rely on inter-machine communication and algorithms to provide rich interaction via diverse human computer interfaces.
