Now, recall from Step 1 that the mincut finder classifies a node n as anaphoric if and only if w sn ≥ 0.5.
hence, to achieve the aforementioned goal, we just need to ensure the property that w sn ≥ 0.5 if and only if P A (m n ) ≥ c. we compute w sn using a sigmoid function: where α is a constant that controls the "steepness" of the sigmoid.
