( 3) In all four examples, the verb and the participating noun phrases Mitarbeiter (employee), Kollege (colleague) and Bericht (report) are identical, and the noun phrases are assigned the same case.
given that the stemmed output of the translation does not tell us anything about case features, in order to predict the appropriate cases of the three noun phrases, we either rely on ordering heuristics (such that the nominative NP is more likely to be in the beginning of the sentence (the German Vorfeld) than the accusative or dative NP, even though all three of these would be grammatical), or we need fine-grained subcategorization information beyond pure syntax.
