### Dataset Summary |
|
|
|
ScandiReddit is a filtered and post-processed corpus consisting of comments from [Reddit](https://reddit.com/). |
|
|
|
All Reddit comments from December 2005 up until October 2022 were downloaded through [PushShift](https://files.pushshift.io/reddit/comments/), after which these were filtered based on the FastText language detection model. Any comment which was classified as Danish (`da`), Norwegian (`no`), Swedish (`sv`) or Icelandic (`is`) with a confidence score above 70% was kept. |
|
|
|
The resulting comments were then deduplicated, removing roughly 438,000 comments. 5,000 comments written by Reddit bots were removed, and roughly 189,000 comments belonging to inappropriate subreddits (explicit and drug-related) were also removed. |
|
|
|
Lastly, we remove roughly 40,000 near-duplicate comments from the resulting corpus, where near-duplicate here means that the comments have more than 80% of their word 5-grams in common. |
|
