Modelling Business to Government (B2G) interaction is considered to be more complex than Citizen to Government (C2G) interaction, since the concept of authorized citizens, representing the Business while interacting with specific governmental organizations should be explored. Novel interaction models should be introduced, transforming the way Governmental services are delivered to Businesses. To this end, we propose a Web 2.0 citizen-centric model facilitating Business to Government interaction by establishing a social network between citizens and public agencies. All kinds of interactions (B2G, G2G) are expressed as C2G interactions establishing the citizen-centric nature of the proposed interaction model. The architecture of a Web 2.0 platform, named MyCCP, based on the suggested interaction model is also presented, along with a case study illustrating business-to-government interaction to indicate the potential of the suggested model.
