Tree Transformations in Data-Driven Dependency Parsing (2009)
Tesnière (1959) is often regarded as the founder of the modern theoretical tradition of dependency grammar, but it is not one well-defined theory. Instead, it comprises several related theories,...

Tree Transformations in Inductive Dependency Parsing (2007)
This licentiate thesis deals with automatic syntactic analysis, or parsing, of natural languages. A parser constructs the syntactic analysis, which it learns by looking at correctly analyzed...

Regression on manifolds using kernel dimension reduction (2007)
We study the problem of discovering a manifold that best preserves information relevant to a nonlinear regression. Solving this problem involves extending and uniting two threads of research. On the...
Generalizing Tree Transformations for Inductive Dependency Parsing (2007)
Jens Nilsson, Joakim Nivre, Johan Hall
Previous studies in data-driven dependency parsing have shown that tree transformations can improve parsing accuracy for specific parsers and data sets. We investigate to what extent this can be...
Single Malt or Blended? A study in Multilingual Parser Optimization (2007)
Johan Hall, Jens Nilsson, Joakim Nivre, Beáta Megyesi, Mattias Nilsson, Markus Saers
We describe a two-stage optimization of the MaltParser system for the ten languages in the multilingual track of the CoNLL 2007 shared task on dependency parsing. The first stage consists in tuning a...
Converting Dependency Treebanks to MALT-XML (2006)
In data-driven approaches to natural language processing, a common problem is the lack of data for many languages. Within the project Stochastic Dependency Grammars for Natural Language Parsing at...
Reconstruction of the Swedish Treebank Talbanken. (2006)
Data-driven parsing techniques have a number of advantages over rule-based parsing techniques, such as fast development time, broad-coverage and robustness. Treebanks, collections of syntactically...

CoNLL-X SharedTask: Multi-lingual Dependency Parsing (2006)
The goal of this report is to summarize our experiments and present the final result of our participation in the CoNLL-X Shared Task 2006. The topic of this year's shared task was multi-lingual...
Labeled pseudo-projective dependency parsing with Support Vector Machines (2006)
Joakim Nivre, Johan Hall, Jens Nilsson, Svetoslav Marinov
◮ Deterministic algorithm for building labeled projective dependency graphs in linear time [Nivre 2006a]
Graph transformations in data-driven dependency parsing (2006)
Transforming syntactic representations in order to improve parsing accuracy has been exploited successfully in statistical parsing systems using constituency-based representations. In this paper, we...
MaltParser: A data-driven parser-generator for dependency parsing (2006)
Joakim Nivre, Johan Hall, Jens Nilsson
We introduce MaltParser, a data-driven parser generator for dependency parsing. Given a treebank in dependency format, MaltParser can be used to induce a parser for the language of the treebank....
