+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.

+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
