Ethnographic data describing the Alyawarra-speaking Aboriginal people of central Austraila collected from 1971-1972 by Woodrow Denham. This is the source data for the Kinships Dataset commonly used in knowledge graph completion benchmarks.
The Kinships dataset is commonly used, but the context and source data for the benchmark is challenging to find online. I've re-uploaded it here from the (currently down as of Oct. 2023) Kinsources.net database permalink. A paper describing the history of this dataset in machine learning research can be found here, and additional resources can be found in the publication section of the author's ResearchGate profile.
Historically, western research on indigenous peoples has been ethically frought. The original author of this data, Denham, has written a document outlining his views and recollection about the circumstances of this data collection. You can read that document here. As this data was collected over 50 years ago, it is challenging to find additional context beyond that from Denham. If anyone has additional information about the ethics or context of this dataset I encourage them to share it as a GitHub issue.
