Abstract:
In the last few decades, topic models have been extensively used to discover the latent
topical structure of large text corpora; however, very little has been done to model the
continuation of such topics in the near future. In this paper we present a novel approach
for tracking topical changes over time and predicting the topics which would continue in
the near future. For our experiments, we used a publicly available corpus of conference
papers, since scholarly papers lead the technological advancements and represent an
important source of information that can be used to make decisions regarding the funding
strategies in the scientific community. The experimental results show that our model
outperforms two major baselines for dynamic topic modeling in terms of predictive power.
