For example, consider the sentence: "It also marks P&G's growing concern that its Japanese rivals, such as Kao Corp., may bring their superconcentrates to the U.S." According to our annotation style, there is a relation "rivals" between "P&G" and "Kao Corp." in this sentence.
the original annotations for PENN-100 consider only the relation between "Kap Corp." and the pronoun "it", leaving the task of resolving the coreference between "P&G" and "it" as a posterior step.
