README
Categories have the format i-j:CAT where i and j are the indices of the spaces
between words in the TARGET language.  For example, slash categories can be written:

  the blue house
  0-1:DT 1-2:JJ 2-3:NN 1-3:NBAR 0-2:NP/NN 0-3:NP


You may multiply label each span, e.g.

  NP
   |
 NBAR
   |
  NN
   |
 John
  0-1:NP 0-1:NBAR 0-1:NP

However, this may result in a very large number of rules being extracted.

* Filtering and Scoring of Unscored and Unfiltered Grammars
****

Take the unfiltered grammar, and a test set, and run:
./filter_grammar <test set> < unfiltered.grammar > filter.grammar

Then, to score the new filtered grammar, run:
./score_grammar <alignment> < filtered.grammar > scored.grammar

Something went wrong with that request. Please try again.
