Word cloud for 20 topics of TRSAwardeeSet For TRSAwardeeSet, we use wordle to generate word cloud for top 20 words of each topic and then put all word clouds into one slide for visualization. The 20 topics are order from left to right and from up to down. The size of words reflect the proportion of each word in that topic. Note, the word is not really word, instead, a stem.
