Moreover, relations between real-world entities are more often events than relations between common nouns.
a more flexible approach is to represent relations as lexicalized paths in dependency graphs (Lin and Pantel, 2001;Szpektor et al., 2004), sometimes with semantic postprocessing (Shwartz et al., 2017b) and/or retransforming into textual patterns (Nakashole et al., 2012).
