We extend PROFINDER to leverage this intuition by incorporating a "stickiness" prior (Haghighi and Vanderwende, 2009) to encourage neighboring clauses to stay in the same frame.
along with introducing the background frame, the frame transition component now becomes where β is the stickiness parameter, and the event transition component correspondingly becomes Argument dependencies as caseframes As noticed in previous work such as Chambers and Jurafsky (2011), the combination of an event head and a dependency relation often gives a strong signal of the slot that is indicated.
