One of the ways of avoiding this problem is to exclude relational nouns which are words with non-zero valency (Koptjevskaja-Tamm et al., 2015) from the dataset, so it should consist only of zero valency nouns that are more properly linked with real world objects.
the distinction of words on relational and non-relational ones is fuzzy, and such assessments could be very subjective (also, since verbs are usually highly relational, they should not be used in cross-language evaluation).
