Correlation between disease case counts and temporal topic distributions or trends (ξz) extracted by EpiNews for (a) whooping cough, (c) rabies, (e) salmonellosis, and (g) E. coli infection in U.S. Along with the temporal topic trends (ξz), we also showed the correlation between disease case counts and sampled case counts (generated by multinomial sampling from temporal topic trends) for (b) whooping cough, (d) rabies, (f) salmonellosis, and (h) E. coli infection. Note, the sampled case counts and disease case counts share almost similar numerical range. However, the temporal topic trend values are at different numerical range (ranging from 0 to 1) with respect to the disease case counts.
