1.1. Dual dependency

Dual dependency represents a specific case of dependency. The term dual dependency covers such cases in which a modification (both valency and non-valency) has a dual semantic dependency relation, i.e. it simultaneously modifies a noun and a verb (which can be nominalized). The dependency on a noun is often expressed also formally (by agreement in the grammatical categories).

We distinguish these two cases:

With modifications with a dual dependency expressed by a verb form, the grammatical coreference relations are also represented in the tree. For details see Section 2.3, "Coreference with verbal modifications that have dual dependency".
