Microsoft Academic Graph

There were no changes to the files except compressing them with zstd (-T8 -19). This results in a smaller packed size, but still more data than the previous version.

The compressed files will expand to the following sizes (output of zstd -l):

This data is not the whole set what you get to download, there is much more (roughly 160GiB compressed), but the upload quota only permits this much. The additional data is retained and you may ask for it. The additional data is huge, so be prepared to provide sftp, rsync or similar access to drop the files in.

If you want to donate an update but lack the bandwidth to download and repack the set, feel free to contact me (details via my ORCiD page), once you have gone through the provisioning steps. I'll either grab the set directly from the azure storage (you might have to give me access rights) or provide an sftp/rsync drop for you to dump the data in.

The data for version 2021-09-13 was kindly contributed by Rudolf Siegel
