Recent methods (Mitchell and Lapata, 2008;Erk and Padó, 2008;Thater et al., 2010) exploit direct syntactic/semantic relations with target words, but these methods would still fail in the above examples, because the direct structural neighbors of banks are the same in the two contexts.
syntactic/semantic structural co-occurrences of multiple words, obtained from the dependency relations, seem effective for this example.
