How to join documents and quality signals when downloading directly
I've downloaded the documents and quality signals separately with wget
Surprisingly, I don't see which primary key I can use to re-join the two data sources. How can I do this?
Hi @tgshdyfuhuf
Each quality signal has a field "id" which points to the idx of the corresponding record in the documents files. For example the id 2023-06/0000/de_head.json.gz/262
means that the signal is associated with document 262
(0-indexed) in the documents file 2023-06/0000/de_head.json.gz
.
@mauriceweber
safe assumption to make that each signals file will only contain ids pointing to the same namespaced documents file
ie. signals 2023-06/0000/de_head.json.gz
will only contain signals for document 2023-06/0000/de_head.json.gz
yes exactly -- there is a one-to-one correspondence between rows in the signals file and rows in the documents file
