Commonly, the result of referring expression generation algorithms is a single noun phrase. In interactive settings with a shared workspace, however, human dialog partners often split re- ferring expressions into installments that adapt to changes in the context and to actions of their partners. We present a corpus of human?human interactions in the GIVE-2 setting in which in- structions are spoken. A first study of object descriptions in this corpus shows that refer- ences in installments are quite common in this scenario and suggests that contextual factors partly determine their use. We discuss what new challenges this creates for NLG systems.
