With the rapid growth of Web 2.0, social media
has become a prevalent information sharing and spreading
platform, where users can retweet interesting messages. To better
understand the propagation mechanism for information diffusion,
it is necessary to model the user retweeting behavior and predict
future retweets. Some existing work in retweeting prediction
based on matrix factorization focuses on using user-message
interaction information, user information and social influence
information, etc. The challenge of improving prediction
performance is how to jointly perform deep representation of
these information to solve the sparsity problem and then learn a
more comprehensive retweeting behavior model. Inspired by
word2vec and co-factor matrix factorization model, this paper
proposes a hybrid model, called HCFMF, for learning users’
retweeting behavior, it first computes the message content
similarity by considering the message co-occurrence, the author
information and word2vec based low-dimensional representation
of content, then, jointly decomposes the user-message matrix and
message-message similarity matrix based on a co-factorization
model. We empirically evaluate the performance of the proposed
model on real world weibo datasets. Experimental results show
that taking the dense representation of author and content
information into consideration could allow us make more
accurate analysis of users’ retweeting patterns. The mined
patterns could serve as a feedback channel for both consumers
and management departments.
