Analyzing and Visualizing Productivity of a University

Originally posted by Carsten Keßler at Lodum.de.

One of the main goals of Linked Open Data University of Muenster (LODUM) project is to open up the university’s data silos, integrate the data, and make it easy to build applications on top of the data collection. This productivity map for Google Earth is an example of such an application. It renders the university buildings in 3D – the building height indicates the number of publications written by researchers working in the respective building.

The absolute number of papers is normalized by the number of researchers working in the given building for a more balanced impression. The buildings are split in two parts:

  1. the lower part indicates the number of journal papers, and
  2. the upper part represents all other publications.

Clicking either of these two parts opens a pop-up with the actual numbers. The distribution of publications between the different institutions in a building is visualized as a pie chart (generated by the Google Chart Tools). The pop-ups also include links to the SPARQL queries to pull the data for the given building out of our store, so that interested developers can learn how we built this map.

The KML file is also available for download—just open it up in Google Earth to explore the productivity map.

The following publication explains the visualization. Please use it for citing the project.
