Towards Weakly Supervised Resolution of Null Instantiations

Philip John Gorinski, Josef Ruppenhofer, Caroline Sporleder

Abstract: This paper addresses the task of finding antecedents for locally uninstantiated arguments. To resolve such null instantiations, we develop a weakly supervised approach that investigates and combines a number of linguistically motivated strategies that are inspired by work on semantic role labeling and corefence resolution. The performance of the system is competitive with the current state-of-the-art supervised system.
