It is widely recognized that the proliferation of annotation schemes runs counter to the need to re-use language resources, and that standards for linguistic annotation are becoming increasingly mandatory. To answer this need, we have developed a representation framework comprised of an abstract model for a variety of different annotation types (., morpho-syntactic tagging, syntactic annotation, co-reference annotation, etc.), which can be instantiated in different ways depending on the annotators approach and goals. . | A Common Framework for Syntactic Annotation Nancy Ide Department of Computer Science Vassar College Poughkeepsie NY 12604-0520 USA ide@ Laurent Romary LORIA CNRS Campus Scientifique . 239 54506 Vandoeuvre-l -Nancy .

In this paper we provide an overview of our representation framework and demonstrate its applicability to syntactic annotation. We show how the framework can contribute to comparative evaluation and merging of parser output and diverse syntactic annotation schemes. 1 Introduction It is widely recognized that the proliferation of annotation schemes runs counter to the need to re-use language resources and that standards for linguistic annotation are becoming increasingly mandatory. In particular there is a need for a general framework for linguistic annotation that is flexible and extensible enough to accommodate different annotation types and different theoretical and practical approaches while at the same time enabling their representation in a pivot format that can serve as the basis for comparative evaluation of parser output such as PARSEVAL Harrison et al. 1991 as well as the development of reusable editing and processing tools. To answer this need we have developed a representation framework comprised of an abstract model for a variety of different annotation types . morpho-syntactic tagging syntactic annotation co-reference annotation etc. which can be instantiated in different ways .
