Vector Representation of Words for Detecting Topic Trends over Short Texts

Liyan He, Yajun Du, Lei Zhang
It is a critical task to infer discriminative and coherent topics from short texts. Furthermore, people not only want to know what kinds of topics can be extract from these short texts, but also desire to obtain the temporal dynamic evolution of these topics. In this paper, we present a novel model for...
