Link-PLSA-LDA: A new unsupervised model for topics and influence of blogs.
Summary
This paper presents a novel, unsupervised model based of topics and topic specific influences in blogs. It is compared with Link-LDA and performs better. It intends to address two issues at once: topic discovery and modeling topic specific influence of blogs.
When one blog cites another, this is viewed as a uni-dimensional link.
Not completely generative due to hyperlinked documents being fixed.
