Web 3.0 refers to a proposed next stage in the development of the World Wide Web focused on semantics, artificial intelligence, and a greater degree of user control over personal data and identity. Some key aspects of Web 3.0 include more personalized experiences through user profiling, intelligent applications that can interpret web pages, and an emphasis on open technologies and portable digital identity. While there is no consensus on a definition, many see Web 3.0 being powered by semantic web technologies to add meaning and enable systems that can reason like humans.
