Reddit r/AskScience Flair Dataset

Reddit is a social news, content-rating and discussion website, and one of the most popular sites on the internet. It is organised into communities called subreddits, and this dataset focuses on r/AskScience, where users post and discuss science questions.

The data was collected from the r/AskScience subreddit between December 2015 and May 2026, and contains 982,762 posts across 22 columns. It includes information about the questions asked on the subreddit, the description of each submission, the flair of the question, NSFW or SFW status, the year of submission, engagement metrics, and more. The older data (up to May 2022) was extracted using Python and Pushshift's API. The more recent data (from mid-2022 onward) was collected from Arctic Shift, a maintained successor to Pushshift, since Pushshift's public API was discontinued. Some cleaning was done using NumPy and pandas.

The dataset contains the following columns:

1. id - ID of the submission.
2. author - Redditor name.
3. author_fullname - Redditor's account identifier.
4. domain - Domain of the submission.
5. question - The question asked in the submission (post title).
6. link_flair_css_class - CSS class used to identify the flair.
7. link_flair_text - The flair's text content on the post.
8. description - Description (body text) of the submission.
9. contest_mode - Contest mode, which obscures scores and randomises sorting.
10. created_utc - Date and time the submission was created.
11. year - Year of the submission.
12. edited - Whether the post was edited (0 if not, otherwise the edit time).
13. retrieved_on - Date and time the submission was retrieved.
14. over_18 - Whether the submission is marked as NSFW.
15. is_self - Whether the submission is a self (text-only) post.
16. locked - Whether the submission has been locked.
17. num_comments - Number of comments on the submission.
18. score - Number of upvotes for the submission.
19. spoiler - Whether the submission is marked as a spoiler.
20. stickied - Whether the submission is stickied.
21. thumbnail - Thumbnail of the submission.
22. banned - Whether the post was removed by a moderator (Yes or No).

This dataset can be used for flair prediction, NSFW classification, and various text mining and NLP tasks. Exploratory data analysis can also be done to find insights and see trends and patterns over the years.
