"Data-driven Assessment of Structural Evolution of RDF Graphs"

Example of Positive Delta (back to main page)

The following images show the difference in structure between the initial and final states of a local update that has a positive delta according DBpedia 2015-10 code tables. They have been drawn using http://visgraph3.org/

Initial State Final State

In the following log excerpt, we can see the PCB transactions of the initial and final states of a local update , as well as the codes used to codify them. In this case, we can see how the addition of new information (i.e., items), has connected new resources and has moved the global status to structure more relevant in the RDF graph.

In the following table, we can see how the vocabulary used in both states of the update has not been modified, only the relationships between the instances, which have made the resulting structure more structurally coherent within the data:
