Automatic Feature Selection for Agenda-Based Dependency Parsing
Miguel Ballesteros, Bernd Bohnet · University of Birmingham Research Portal (University of Birmingham) · 2014
In this paper we present an in-depth study on automatic feature selection for beam-search dependency parsers. The search strategy is inherited from the one implemented in MaltOptimizer, but searches in a much larger set of feature templates that could lead to a higher number of combinations. Our models provide results that are on par with models trained with a larger set of feature templates, and this implies that our models provide faster training and parsing times. Moreover, the results establish the state of the art for some of the languages.
