什么是search.twitter.com的＆QUOT;热门话题＆QUOT;算法？ [英] What is search.twitter.com's "trending topics" algorithm?

问题描述

什么算法没有微博的使用，以确定的10个主题，你可以在 search.twitter.com 看到了什么？我想实现的算法，我也想表现出50个最热门的话题（而不是10）。你能形容最有效的算法？

What algorithm does twitter use to determine the 10 topics that you can see at search.twitter.com? I would like to implement that algorithm and I would also like to show the 50 most popular topics (instead of 10). Can you describe the most efficient algorithm?

谢谢！

另外，我也希望能够通过公共timeline- <一个搜索来实现算法href="http://twitter.com/statuses/public_timeline.rss">http://twitter.com/statuses/public_timeline.rss

Also, I would like to be able to implement the algorithm by searching through the public timeline- http://twitter.com/statuses/public_timeline.rss

推荐答案

Twitter的趋势算法不只是量的关键字。这是它的一部分，但也有一个衰减因子，使贾斯汀beiber是不是顶部趋势下去。

Twitter's trending algorithm is not just volume of keywords. That's part of it, but there's also a decay factor so that "justin beiber" isn't top trending forever.

This post on quora backs this up. http://www.quora.com/Trending-Topics-Twitter/What-is-the-basis-of-Twitters-current-Trending-Topics-algorithm?q=trending+algorithm

衰减通常是使用算法中的职位相对年龄，给予更高的权重进行更新的主题/职位/等。

decay is typically done by using the relative age of the post in the algorithm, giving more weight to newer topics/posts/etc.
