Then we will find the constituent containing the target noun which marks the frame element in which the noun is serving, and identify that frame element.
given the target knife, for a sentence like I tried to slice the ham with a dull knife we would mark slice as the governor, indicate CUTTING as the name of the frame, select the phrase with a dull knife as the phrase containing the target which identifies a frame element of slice in that sentence, and give its name as INSTRUMENT.
