Change-a-LOD: does the schema on the linked data cloud change or not?

Abstract Recent work analyzing changes on the Linked Open Data (LOD) cloud on fine-grained weekly snapshots shows that vocabularies published on the cloud are highly static. While this result is quite expected, there is another kind of schematic information that can be observed on the LOD cloud: the use of the vocabularies in the cloud. With use, we mean the combinations of sets of properties and sets of types to describe the resources in a specific domain. Current literature does not tackle this question sufficiently. In order to gain insight into how the use of vocabularies on the LOD cloud changes over time, we present illustrating examples and a formalization of the research question. Subsequently, we present early results of experiments applied on weekly snapshots that show that the use of vocabularies indeed changes quite a lot over time. 1
