Abstract
The increasing use of social media by governments for improving citizen access to information, participation of stakeholders in policy processes and delivery of customer-focused services are among the defining features of the so-called "Governance 2.0" phenomenon. Another feature is the interaction between existing government networks and social networks of citizens and policy actors in order to disseminate government information and seek contributions from citizens and other actors to policies, decisions and services. This article examines the semantic issues associated with the emerging Governance 2.0 networks. It evolves an architectural framework to guide governments and their agencies in developing semantic interoperability capabilities. We approach the problem by first developing a conceptual model for analyzing semantic interoperability requirements in general. Next, we provide a case study to generate interesting scenarios and identify concrete semantic interoperability issues arising from the interactions between citizens, businesses and government through traditional and electronic channels and different forms of social media. Subsequently, we present a Semantic Interoperability Architecture Framework to address these issues based on existing government semantic interoperability frameworks and semantic standards for Web 2.0. After validating the prescribed framework, we discuss how it could be used in practice by governments.
