Source: {"body":{"en":"The ranking of comments uses upvotes−downvotes. \r\n\r\nThanks to David Ruescas (nVotes), I found a blog post from 2009 remarking that this is a wrong strategy (http://www.evanmiller.org/how-not-to-sort-by-average-rating.html). For instance, a comment with 100 upvotes and 0 downvotes and a comment with 1000 upvotes and 900 downvotes would be equally scored. One could expect this would be solved using the average rating (upvotes/(upvotes+downvotes)), however, such strategy is also inappropriate because there will be many comments with few votes and, therefore, high uncertainty.\r\n\r\nTo solve the above problem, the blog post suggests using the lower bound of the Wilson score confidence interval. Please find the formula implemented in Ruby in the blog post, as well as this detailed explanation of why Reddit is using this method https://medium.com/hacking-and-gonzo/how-reddit-ranking-algorithms-work-ef111e33d0d9"},"title":{"en":"Improve the score of comments"}}

This fingerprint is calculated using a SHA256 hashing algorithm. In order to replicate it yourself, you can use an MD5 calculator online and copy-paste the source data. ×
