Given a NE e i and a syntactic context c j , we now introduce the contextual cluster assignment matrix A ctxt (e i , c j ) as follows: A ctxt (e i , c j ) = clu * where: clu * = Argmax {clu l :clu l e i ;Fe(e i ,clu l )>1} F c (c j , clu l ).
clu * is the cluster for which we find more than one occurrence of e i and the highest score related to the context c j .
