Comparison heatmaps of the four attention weight coefficients. The scales of the abscissa and ordinate represent the words in the sentence. The words on the ordinate depend on the words on the abscissa. The numbers denote the correlation coefficients. The colour depth represents the degree of dependency between words. The darker the colour is, the stronger the dependencies between words, while the lighter the colour is, the weaker the dependencies between words
