Although the role hierarchy was expected to generalize semantic roles, no positive results for role classification have been reported (Baldewein et al., 2004).
the generalization of semantic roles across different frames has been brought up as a critical issue for FrameNet (Gildea and Jurafsky, 2002;Shi and Mihalcea, 2005;Giuglea and Moschitti, 2006) In this paper, we explore several criteria for generalizing semantic roles in FrameNet.
