  Web 3.0 promises to have a significant effect in users and businesses. It
will change how people work and play, how companies use information to market
and sell their products, as well as operate their businesses. The basic shift
occurring in Web 3.0 is from information-centric to knowledge-centric patterns
of computing. Web 3.0 will enable people and machines to connect, evolve, share
and use knowledge on an unprecedented scale and in new ways that make our
experience of the Internet better. Additionally, semantic technologies have the
potential to drive significant improvements in capabilities and life cycle
economics through cost reductions, improved efficiencies, enhanced
effectiveness, and new functionalities that were not possible or economically
feasible before. In this paper we look to the semantic web and Web 3.0
technologies as enablers for the creation of value and appearance of new
business models. For that, we analyze the role and impact of Web 3.0 in
business and we identify nine potential business models, based in direct and
undirected revenue sources, which have emerged with the appearance of semantic
web technologies.
