Let $c_i$ be the total count of occurrences of an argument from $s_i$ in the review texts. Then

$$\tau_{i,j}=\frac{n_{i,j}}{c_i}$$

is a relative measure for how often an argument from $s_i$ appears in conjunction with an argument from $s_j$. If we scale $\hat{v}_{i,j}$ by $\tau_{i,j}$, we obtain a more accurate measure for relatedness,
