Dataset Description:

The Stack Exchange Data Dump is a quarterly, anonymized release of all user-contributed content from the Stack Exchange network, including posts, comments, votes, and user data, licensed under the Creative Commons BY-SA 3.0. These features facilitated comprehensive analyses of user interactions, content quality, and community dynamics within the Stack Exchange network. As of March 1, 2020, the Stack Exchange Data Dump contained a total of 47,931,101 posts, encompassing both questions and answers, accumulated from 2008 to that date. The size of the data dumps varied over time, reflecting the growth of the platform. For instance, the January 2011 dump exceeded 3 GB. As the network expanded, subsequent dumps increased in size, with later versions reaching tens of gigabytes. Each data dump captured the state of the Stack Exchange network up to the date of its release, providing a temporal snapshot of user-generated content and activity. The dumps were released quarterly, offering periodic insights into the evolving dynamics of the platform. Structurally, the dataset is organized into multiple tables, each corresponding to different aspects of the platform:

Posts: Contained all questions and answers, including metadata such as post ID, score, and content.
Users: Included user-related information like user ID, reputation score, and profile details.
Votes: Recorded voting activity on posts, specifying vote types and associated post IDs.
Comments: Held all comments made on posts, detailing comment text, scores, and related post and user IDs.
Badges: Documented badges awarded to users, noting badge names, dates awarded, and badge classes (e.g., bronze, silver, gold).
Post History: Tracked changes to posts, recording edits, rollbacks, and other modifications along with details on the post and the user making the change.
Post Links: Contained links between posts, such as duplicates or related posts, along with link types and creation dates.
