Message forwarding (e.g.
retweeting on Twitter.com) is one of the most popular functions in many existing microblogs
and a large number of users participate in the propagation of information
for any given messages. While this large number can generate notable diversity and not all users have the same ability to diffuse the messages
this also makes it challenging to find the true users with higher spreadability
those generally rated as interesting and authoritative to diffuse the messages. In this paper
a novel method called SpreadRank is proposed to measure the spreadability of users in microblogs
considering both the time interval of retweets and the location of users in information cascades. Experiments were conducted on a real dataset from Twitter containing about 0.26 million users and 10 million tweets
and the results showed that our method is consistently better than the PageRank method with the network of retweets and the method of retweetNum which measures the spreadability according to the number of retweets. Moreover
we find that a user with more tweets or followers does not always have stronger spreadability in microblogs.
