Using 1-, 2-and 3-word sequences from the text, the strongest associations for the action clusters are shown in Figure 4, and we see that clusters 1 [come-closer] and 2 [move away] have strongest associations with "move toward each" and "move away", but these are not very dominant over other competitors.
for clusters 3 and 4 [chase], there is a strong association with the word "chase".
