CoNLL X Shared Task

We present a two-stage multilingual de- pendency parser and evaluate it on 13 diverse languages. The first stage is based on the unlabeled dependency pars- ing models described by McDonald …...

We describe an online learning depen- dency parser for the CoNLL-X Shared Task, based on the bottom-up projective algorithm of Eisner (2000). We experi- ment with a large feature set …...

Three versions of the Covington algorithm for non-projective dependency parsing have been tested on the ten different languages for the Multilingual track of the CoNLL- X Shared Task. The results …...

We introduce a new approach to transition- based dependency parsing in which the parser does not directly construct a depen- dency structure, but rather an undirected graph, which is then …...

In this paper, we show that significant im- provements in the accuracy of well-known transition-based parsers can be obtained, with- out sacrificing efficiency, by enriching the parsers with simple transitions …...
