For example, consider the sentence "In relation to Bush's axis of evil remarks, the German Foreign Minister also said, Allies are not satellites, and the French Foreign Minister caustically criticized that the United States' unilateral, simplistic worldview poses a new threat to the world".
after parsing the sentence, it extracts features such as the syntactic path information between each candidate <H> and the expression <E> and a distance between <H> and <E>.
