Stack Exchange — ai.stackexchange.com
The content of ai.stackexchange.com (https://ai.stackexchange.com/), a Stack Exchange question-and-answer site, as published in the Stack Exchange Data Dump of April 2024 on the Internet Archive. The posts table holds 56,113 rows: 26,764 posts (12,380 questions, 12,460 answers, 954 tag wiki excerpts, 954 tag wikis, 13 posts of type 6 and 3 posts of type 7) and 29,349 comments, written between 2 August 2016 and 31 March 2024. Beside it are 71,811 user accounts, 93,175 votes, 62,748 badges awarded, 986 tags, 105,993 post revisions and 1,792 links between posts. Every answer keeps the question it answers and every comment the post it was written on, so the threads can be rebuilt. The Internet Archive item describes the dump as anonymised; the votes table names the voter in only 307 rows.
