The Penn Treebank has recently implemented a new syn- tactic annotation scheme, designed to highlight aspects of predicate-argument structure. This paper discusses the implementation of crucial aspects of this new annotation scheme. It incorporates a more consistent treatment of a wide range of grammatical phenomena, provides a set of coin- dexed null elements in what can be thought of as "underly- ing" position for phenomena such as wh-movement, passive, and the subjects of infinitival constructions, provides some non-context free annotational mechanism to allow the struc- ture of discontinuous constituents to be easily recovered, and allows for a clear, concise tagging system for some semantic roles.
