LAF/GrAF-grounded Representation of Dependency Structures
1 LREC 2010 - 7th Language Resources and Evaluation Conference, Valetta, Malta, ELRA, 5/2010
This paper shows that a LAF/GrAF-based annotation schema can be used for the adequate representation of syntactic dependency structures in many languages. We first argue that there are at least two types of textual units that can be annotated with dependency information: words/tokens and chunks/phrases. Based on this consideration, we discuss a sub-typing of GrAF to represent the corresponding dependency structures. We then describe a wrapper program that, as a proof of concept, converts output data from different dependency parsers in proprietary XML formats to the GrAF-compliant XML representation.
