We present an implemented system for the resolution of it, this, and that in tran- scribed multi-party dialog. The system han- dles NP-anaphoric as well as discourse- deictic anaphors, i.e. pronouns with VP an- tecedents. Selectional preferences for NP or VP antecedents are determined on the basis of corpus counts. Our results show that the system performs significantly better than a recency-based baseline.
