Universal Dependencies v1: A Multilingual Treebank Collection
Joakim Nivre,Marie-Catherine de Marneffe,Filip Ginter,Yoav Goldberg,Jan Hajič,Christopher D. Manning,Ryan McDonald,Slav Petrov,Sampo Pyysalo,Natalia Silveira,Reut Tsarfaty,Daniel Zeman +11 more
TL;DR: This paper describes v1 of the universal guidelines, the underlying design principles, and the currently available treebanks for 33 languages, as well as highlighting the needs for sound comparative evaluation and cross-lingual learning experiments.

MaltParser: A language-independent system for data-driven dependency parsing
Joakim Nivre,Johan Hall,Jens Nilsson,Atanas Chanev,Gülşen Eryiğit,Sandra Kübler,Svetoslav Marinov,Erwin Marsi +7 more
TL;DR: Experimental evaluation confirms that MaltParser can achieve robust, efficient and accurate parsing for a wide range of languages without language-specific enhancements and with rather limited amounts of training data.
Proceedings Article
The CoNLL 2007 Shared Task on Dependency Parsing
Joakim Nivre,Johan Hall,Sandra K"ubler,Ryan McDonald,Jens Nilsson,Sebastian Riedel,Deniz Yuret +6 more
TL;DR: The tasks of the different tracks are defined and how the data sets were created from existing treebanks for ten languages are described, to characterize the different approaches of the participating systems and report the test results and provide a first analysis of these results.
Proceedings Article
An efficient algorithm for projective dependency parsing
TL;DR: This paper presents a deterministic parsing algorithm for projective dependency grammar that has been experimentally evaluated in parsing unrestricted Swedish text, achieving an accuracy above 85% with a very simple grammar.
Proceedings Article
MaltParser: A Data-Driven Parser-Generator for Dependency Parsing
TL;DR: MaltParser is introduced, a data-driven parser generator for dependency parsing given a treebank in dependency format and can be used to induce a parser for the language of the treebank.
