IMDb权威认证是什么

IMDB 基于网友的个性海量评分，其核心排名算法如下：

　The formula for calculating the Top Rated 250 Titles gives a true Bayesian estimate:
　　weighted rating (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C
　　
　　where:
　　R = average for the movie (mean) = (Rating)
　　v = number of votes for the movie = (votes)
　　m = minimum votes required to be listed in the Top 250 (currently 3000)
　　C = the mean vote across the whole report (currently 6.9)
　　
　　for the Top 250, only votes from regular voters are considered.
