DBpedia ATLAS (GOSPER curve)

This experiment shows a little part of DBpedia: the Event sub-hierarchy. It represents it as a map in which the regions are the ontological classes in the sub-hierarchy. Moreover, in order to create the regions, a GOSPER curve has been used for the cell displacement. Each cell has an hexagonal shape and it represents a DBpedia entity. Hence, the area of each region shows the size of a class in the overall Event hierarchy. The different region lines (solid, dashed and with different thickness) give the class depth in the hierarchy.

The map shows 45377 cells (entities) and 24 regions (ontological classes).

Future works will include:

• Information about the cells;

• Region labeling;

• Semantic Zoom.
