University of Pennsylvania Specificity is an important characterization of texts potentially beneficial for a range of applications such as automatic summarization, text simplification and sentiment analysis. Yet how do we assess specificity? How do terms lack in specificity connect with the full text discourse? In this talk I present our work that links sentence specificity with the discourse relation “instantiation”. First I will present SPECITELLER, a fast and effective semi-supervised system for predicting sentence specificity. Crucially the system relies on bootstrapping lexical usage of the “instantiation” relation. I will further discuss insights into different types of the lack of specificity in a sentence. In the second part of the talk, I will present our improved prediction of “instantiation” and its link with specificity.
