Statistics for the BEAR-C dataset
The change-ratio is a measure of the magnitude of changes with respect to the size of the data.
The vocabulary-dynamicity measures the amount of vocabulary terms (IRIs, literals, or blank nodes) present in a changeset (i, j) relative to the total amount of terms in the graph i and j.
The growth-ratio measures the growth of the data from one version to the next.
The entity-changes metric measures the number of entities that were added or deleted between two versions fo the data.
The triple-to-entity-change metric shows the average number of triples involved in an entity-change.
Object updates are changes of triples (s p o1) to (s p o2) which were not part of any entity-change.
