Early detection method for emerging topics based on dynamic bayesian networks in micro-blogging networks

作者:

Highlights:

• We propose a new method for early detection of emerging topics in micro-blogging.

• We find two characteristics of emerging topic which influence topic diffusion.

• We build a new DBN-based model to represent the temporal evolution of keyword.

• Performance of our method leads one to two hours earlier than others.
