These initiatives have been launched and maintained by a variety of government organisations with different strategies and technical capacities and under...

Government agencies all over the world are making big investments for developing information systems that open important data they possess to the society, in order to be used for scientific, commercial and political purposes. It is important to understand what value they create and how, and at the same time – since this is a relatively new type of...

The opening of government data, in order to have both social and economic value generated from them, has attracted the attention and interest of both researchers and practitioners from various disciplines, such as information systems, management sciences, political and social sciences and law. Despite the rapid growth of this multidisciplinary rese...

Two important trends in government that are emerging in the recent years have been on one hand the exploitation of the Web 2.0 social media, supporting a more extensive interaction and collaboration with citizens, and on the other hand the opening of government data to the citizens through the Internet, in order to be used for scientific, commercia...

Value creation and innovation by a range of stakeholders, including citizens, analysts, journalists, non-profit entities, etc. are the hallmarks of Open Government Data (OGD) initiatives. At the same time, availability and interoperability of datasets are determined as two of the most important factors for value creation. In parallel, the United Na...

The generation of social and economic value from the vast quantities of data opened by governments has been much lower than the initial expectations. It requires the development and cooperation of ecosystems composed of various public, private, and non-profit actors. For the development of these ecosystems in order to generate social and economic v...
