Solution framework
optimal Twitter followees to help disseminate YouTube videos. The solution consists

).
5.4.1 Topic Discovery
Twitter emerges as an efficient information propagation platform due to its followee-
follower architecture. Twitter followees, especially those with a lot of followers, play
important role as influential leaders, and thus have remarkable promotion value. To
investigate into the following pattern on Twitter and exploit it toward YouTube video
promotion, we identify 11,850 overlapped users who have both Twitter followee
relations and YouTube video-related activity. At Twitter side, we collect the followee
list for each user to obtain 10M following relations.
With user as
document
, and his/her followees as
words
, we apply the stan-
dard LDA to obtain Twitter followee topics and user topic distribution
