This paper presents a joint model for template filling, where the goal is to automatically specify the fields of target relations such as seminar announcements or corporate acquisition events. The approach models mention detection, unification and field extraction in a flexible, feature-rich model that allows for joint modeling of interdependencies at all levels and across fields. | Discriminative Learning for Joint Template Filling Einat Minkov Information Systems University of Haifa Haifa 31905 Israel einatm@ Luke Zettlemoyer Computer Science Engineering University of Washington Seattle Wa 98195 UsA lsz@ Abstract This paper presents a joint model for template filling where the goal is to automatically specify the fields of target relations such as seminar announcements or corporate acquisition events. The approach models mention detection unification and field extraction in a flexible feature-rich model that allows for joint modeling of interdependencies at all levels and across fields. Such an approach can for example learn likely event durations and the fact that start times should come before end times. While the joint inference space is large we demonstrate effective learning with a Perceptron-style approach that uses simple greedy beam decoding. Empirical results in two benchmark domains demonstrate consistently strong performance on both mention detection and template filling tasks. Kcedinger@ Ken Kcedingex . Type emu.
