NAME

Treex::Block::W2A::ParseMSTperl

VERSION

version 0.08055

DECRIPTION

MST parser (maximum spanning tree dependency parser by R. McDonald) is used to determine the topology of a-layer trees. This is its reimplementation in Perl, with simplified MIRA algorithm (single-best MIRA is used).

Settings are provided via a config file accompanying the model file. The script loads the model model_dir/model_name.model and its config <model_dir/model_name.config>. The default is the English model share/data/models/mst_perl_parser/en/conll_2007.model (and conll_2007.config in the same directory).

It is not sensible to change the config file unless you decide to train your own model. However if you do decide to train your own model, then see Treex::Tool::Parser::MSTperl::Config.

TODO: provide a treex interface for the trainer?
