Dataset: dbpedia-live (development version)

DBpedia Live was a real-time service that monitored edits on Wikipedia and published a stream of changes to the DBpedia knowledge graph. This dataset contains only the "added" triples in the stream, so it does not include deletes or other types of changes. Only one month (January 2014) is covered at the moment, but the dataset can be easily expanded in the future (the service stopped functioning in 2021). The stream's elements are irregular in size, depending on the volume of traffic on Wikipedia at a given moment and how the DBpedia Live service was able to cope with it. See also the paper.

The dataset was extensively cleaned to fix or remove bad IRIs, bad Unicode, and invalid literals.

This README is a snapshot of documentation for the latest development version of the dataset. Full documentation for all versions can be found on the website.
