Open Government Data: A Data Analytics Approach

In December 2010 the International Open Government Dataset Search (IOGDS) team at the Tetherless World Constellation at Rensselaer Polytechnic Institute embarked on a project to discover, document and analyze open data catalogs published by governments at various levels around the world. By early 2013 the IODGS project had accumulated descriptive metadata for over 1,022,787 datasets from 192 catalogs in 24 languages, representing 43 countries and international organizations. RPI's aggregate catalog, implemented in RDF and published using both a public SPARQL endpoint and a faceted user interface, has proven to be a valuable tool for gaining insight into the nature of open government data publication. In this article we discuss what our team has learned about international government data publication trends and tendencies through the application of data analytics and data visualization to this metadata collection.

The LOGD project investigates the role of Semantic Web technologies, especially Linked Data, in producing, enhancing and utilizing government data published on Data.gov and other websites. Large portion of government data published on the Web are not necessarily ready for mashups. The Tetherless World Constellation (TWC) is now publishing over 8 billions RDF triples converted from hundreds of government-related datasets from Data.gov and other sources (e.g.
