Because the choice of syntactic constructions in context is governed in part by semantic factors, we focused on English and Romanian because they are the only languages from the set considered here with two productive syntactic options: N N and N P N (English) and genitive-marked N N and N P N (Romanian).
we grouped the English-Romanian parallel instances per each semantic relation and each syntactic construction and checked if the relation was symmetric or not, according to the following definition.
