In other words, the more a G i c is structurally similar to its G m , the better the candidates in this G i c represent their mentions in G m .
we define the context similarity S m (m c , c) between a candidate c and its mention m c using Jaccard similarity in Equation 4: where Θ Gm (m c ) and Θ G i c (c) denote m c 's neighbor set in G m and c's neighbor set in G i c , respectively.
