Towards Visual Overviews for Open Government Data.
Alvaro Graves, Javier Bustos-Jiménez · 2014
The rise of Open Data initiatives has led to the publication of many datasets from different organizations and govern-ments. These datasets cover a wide range of knowledge do-mains, from budget to education to health care. However, not all datasets have the quality, granularity or type of in-formation that is relevant to each user. Moreover, in many cases the description or metadata does not specify clearly the content of a dataset, difficulting the exploration of datasets by stakeholders. In this paper we propose the use of dash-boards and visualizations as a way to preview the content of datasets for easier exploration. The use of visualizations can provide a rapid way to select or discard datasets based on their content, reducing the potential datasets that a user may need to look in order to get what she needs.
