| Description |
The syntactic annotation in UD comes in two versions: a basic representation, where words are connected by syntactic relations into a dependency tree, and an enhanced representation, which is a richer graph structure that adds external subject relations, shared dependents in coordination, and predicate-argument relations in elliptical constructions, among other things. In this talk, I will first explain the principles of the enhanced syntactic representation and review the current UD guidelines. I will then report on recent work that try to automate the prediction of enhanced dependencies, given the basic representation, using both rule-based and data-driven approaches.
