We present a reformulation of the word pair features typically used for the task of disambiguating implicit relations in the Penn Discourse Treebank. Our word pair features achieve significantly higher per- formance than the previous formulation when evaluated without additional fea- tures. In addition, we present results for a full system using additional features which achieves close to state of the art per- formance without resorting to gold syntac- tic parses or to context outside the relation.
