可以从为每一篇文章建立星级评价系统开始。
This could start with a simple star-rating system of each article.
在本例中，我将使用五星级评级系统对电影进行评级。
In this example, I apply the five-star rating system to movies.
该系统有点类似eBay的星级打分系统，但不是对卖家服务进行评价，而是用户对其他用户对社区的贡献进行评分。
Think of it like eBay's "star" ratings, but instead of grading a seller on how quickly an order was shipped, etc., you'd rate each others' contributions to a community.
