Experimental Settings: ACL 2009

The experiments reported in the ACL paper Non-Projective Dependency Parsing in Expected Linear Time were performed using MaltParser (version 1.1) together with a plug-in that can be downloaded here. The table below shows the exact settings used for the three parsers referred to as Su, Sp and Spp, respectively. Links are provided to the XML files specifying the feature models for each combination of parser and language. Default settings were used for all MaltParser parameters that are not explicitly mentioned. (See the MaltParser documentation for more information about flags and parameters.)

Correction 1: The labeled exact match score for Sp on Slovene is incorrect in the published paper. It should be 26.1 (not 29.9).
Correction 2: Contrary to what is stated in the paper, the difference between Su and Spp on Slovene is not statistically significant.
