An integrated framework for treebanks and multilayer annotations

Proceedings of the Third International Conference on Language Resources and Evaluation (LREC 2002)

Abstract

Treebank formats and associated software tools are proliferating rapidly, with little consideration for interoperability. We survey a wide variety of treebank structures and operations, and show how they can be mapped onto the annotation graph model, and leading to an integrated framework encompassing tree and non-tree annotations alike. This development opens up new possibilities for managing and exploiting multilayer annotations.
