Anaphoricity

I am not sure if Hankamer is right in claiming this property for it, but the allied concepts of unstressability and complete anaphoricity certainly are of use in distinguishing relative from interrogative pronouns, particularly undeclined relatives like pu which carry no information about the number, gender, or case of the NP they replace.

We present a discriminative model for single-document summarization that integrally combines compression and anaphoricity constraints.
