Published by European Language Resources Association
We describe the automatic conversion of English Penn Treebank (PTB) annotations into Language Neutral Syntax (LNS) (Campbell and Suzuki, 2002a,b). In this paper, we describe LNS and why it is useful, describe the conversion algorithm, present an evaluation of the conversion, and discuss some uses of the converted annotations and the potential for extending the coverage to other languages. The work described here is in the spirit of other automatic re-annotations of PTB trees (e.g. Frank, 2000 and Meyers, 2001), but differs in the nature of the output.
