Note(s): This table presents the prominence scores (PS) of the top ranking concepts in the ASX listed CEO announcements. The top five concepts are shown in three time period: pre-pandemic, pandemic-shock, pandemic-normal. The PS is defined as the joint probability divided by the product of the marginal probabilities. The score combines the strength and frequency scores using Bayesian statistics to show an absolute measure of correlation between categories and attribute. As the PS scores are >1.0, the co-occurrence happens more often than chance
