| '''Abstract:''' The transition-based approach to dependency parsing has become
| |
| popular thanks to its simplicity and efficiency. Systems like MaltParser
| |
| achieve linear-time parsing with projective dependency trees using locally
| |
| trained classifiers to predict the next parsing action and greedy best-first
| |
| search to retrieve the optimal parse tree, assuming that the input sentence has
| |
| been morphologically disambiguated using a part-of-speech tagger. In this talk,
| |
| I survey recent developments in transition-based dependency parsing that address
| |
| some of the limitations of the basic transition-based approach. First, I show
| |
| how globally trained classifiers and beam search can be used to mitigate error
| |
| propagation and enable richer feature representations. Secondly, I discuss
| |
| different methods for extending the coverage to non-projective trees, which are
| |
| required for linguistic adequacy in many languages.Finally, I present a
| |
| model for joint tagging and parsing that leads to improvements in both tagging
| |
| and parsing accuracy as compared to the standard pipeline approach.

| '''About the Speaker:''' Joakim Nivre is Professor of Computational Linguistics at Uppsala
| |
| University and currently visiting scientist at Google, New York. He holds a
| |
| Ph.D. in General Linguistics from the University of Gothenburg and a Ph.D. in
| |
| Computer Science from Växjö University. Joakim's research focuses on data-driven
| |
| methods for natural language processing, in particular for syntactic and semantic analysis. He is one of the main developers of the transition-based
| |
| approach to syntactic dependency parsing, described in his 2006 book Inductive
| |
| Dependency Parsing and implemented in the MaltParser system. Joakim?s current
| |
| research interests include the analysis of mildly non-projective dependency
| |
| structures, the integration of morphological and syntactic processing for richly
| |
| inflected languages, and methods for cross-framework parser evaluation. He has
| |
| produced over 150 scientific publications, including 3 books, and has given
| |
| nearly 70 invited talks at conferences and institutions around the world. He is
| |
| the current secretary of the European Chapter of the Association for
| |
| Computational Linguistics.
