Trends are popular topics that multiple tweeters are interested in. To identify the top users for a certain trend, we take several considerations into account.
- Highly ranked tweeters should be followed by multiple users.
- Highly ranked tweeters should express sufficient interest in the trend.
- The persons following a highly-ranked user should also be interested in the trend.
- Finally, a good ranking scheme should be able to avoid assigning high ranks to spammy tweeters.
