Abstract

Maltparser is a contemporary dependency parsing machine learning–based system that shows great accuracy. However 90% of the Labelled Attachment Score (LAS) seems to be a de facto limit for these kinds of parsers. In this paper we present an n–version dependency parser that will work as follows: we found that there is a small set of words that are more frequently incorrectly parsed so the n-version dependency parser consists of n different parsers trained specifically to parse those difficult words. An algorithm will send each word to each parser and combined with the action of a general parser we will achieve better overall accuracy. This work has been developed specifically for Spanish using Maltparser.
