The Semantic Web is a grand initiative to make the whole of the Internet machine readable. At the Web 3.0 conference & Expo the discussions were more in tune with how Semantic web would be profitable

Advertising is the main source of income for services on the web and one aim of Semantic Web enthusiasts would be to make advertising more relevant and context based. Its no surprise that most users of the web find advertisements annoying and would love to have their services ad-free. The aim of the Semantic Web could be to bridge that gap between acceptance to annoyance.

Making content more understandable to machines makes it better to crunch more information that could ultimately help in pushing more relevant ads.

Amiad Solomon, CEO of Peer39, a developer of Semantic advertising services, said advertising will also be key to driving Web 3.0's growth.
