Transferring Semantic Roles Using Translation and Syntactic Information

Maryam Aminian, Mohammad Sadegh Rasooli, Mona Diab


Abstract
Our paper addresses the problem of annotation projection for semantic role labeling for resource-poor languages using supervised annotations from a resource-rich language through parallel data. We propose a transfer method that employs information from source and target syntactic dependencies as well as word alignment density to improve the quality of an iterative bootstrapping method. Our experiments yield a 3.5 absolute labeled F-score improvement over a standard annotation projection method.
