FIGURE 1. Dynamic Bayesian Network model of sentiment evolution. Sentiment on a topic i at time t , measured as X t i is dependent on the sentiment at the previous timepoint, X t −1
FIGURE 2. Sequential Monte Carlo sampler for Dynamic Bayesian Networks. Particles (parent sets for topic i ) are sampled for the prior, then through several intermediate stages particles are perturbed with an MCMC kernel, to reach the posterior target.
