The revised Arabic PropBank

The revised Arabic PropBank (APB) reflects a number of changes to the data and the process of PropBanking. Several changes stem from Treebank revisions. An automatic process was put in place to map existing annotation to the new trees. We have revised the original 493 Frame Files from the Pilot APB and added 1462 new files for a total of 1955 Frame Files with 2446 framesets. In addition to a heightened attention to sense distinctions this cycle includes a greater attempt to address complicated predicates such as light verb constructions and multi-word expressions. New tools facilitate the data tagging and also simplify frame creation.
