Representation and parsing of syntactic discontinuities in French constituent treebanks

Abstract

The article introduces novel instanciations of three French constituent treebanks in which certain syntactic phenomena responsible for long-distance dependencies are represented with discontinuous constituents. Resulting trees are mildly context-sentitive structures, and can be modeled with, e.g. LCFRS. We show that such structures can be parsed efficiently, by introducing a neural transition-based discontinuous parser, that also performs morphological analysis and functional tagging. Our experiments show that the sparsity of these phenomena in French treebanks makes learning and evaluation of discontinuous structures difficult.
