A frame-word interaction feature is a binary feature composed of (1) the name of the frame f from which it is created, and (2) an unordered word pair in which the words are taken from two frame elements of f .
for each pair of frame elements f e 1 and f e 2 of a frame f , we cre-ate one frame-word interaction feature from each unordered word pair composed of one word from f e 1 and one word from f e 2 .
