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,
$$r_{i,j} = \hat{v}_{i,j} \times \tau_{i,j} = \frac{v_{i,j}}{c_i}.$$
is a relative measure for how often an argument from $s_i$ appears in conjunction with an argument from $s_j$. If we scale $\bar{v}_{i,j}$ by $\tau_{i,j}$, we obtain a more accurate measure for relatedness,
$$r_{i,j} = \bar{v}_{i,j} \times \tau_{i,j} = \frac{v_{i,j}}{c_i}.$$
Using this formula, we define the \textit{relation matrix}
$$R = V \mathbin{/} \textbf{c},$$
where $\textbf{c}$ is a vector containing the counts $c_i$ for each $s_i \in S$.
