TWILITE: A recommendation system for Twitter using a probabilistic model based on latent Dirichlet allocation

作者:

Highlights:

• We propose a probabilistic model by generalizing LDA to capture the behaviors of users in Twitter.

• A variational EM algorithm is presented for our model.

• We develop recommendation algorithms using the parameters estimated by the inference algorithm.

• We did performance study to show the effectiveness of our model and recommendation algorithms.

• Our recommendation algorithms are much more accurate than traditional algorithms in experiments.
