<p>It is just a simple use of PageRank. We can get more accuracy result by throwing away zombie users. To find zombie users, we can use PageRank in a different way, because they follow a lot of people but none followers.<br>
Or we can using tag to find famous people by calculating PR among people whose tag includes “SPARK”.<br>
<br>
Unlike website, Weibo is interesting because in website, high PR like google has many connection with other websites, but famous people in Weibo only follow several people.
