scfg_train

Train the parameters of a stochastic context free grammar

Synopsis

scfg_train [options [-grammar ifile] [-corpus ifile] [-method string] [-passes int] [-startpass int] [-spread int] [-checkpoint int] [-heap int] [-o ofile]

scfg_train takes a stochastic context free grammar (SCFG) and trains the probabilities with respect to a given bracket corpus using the inside-outside algorithm. This is basically an implementation of Pereira and Schabes 1992.

Note using this program properly may require months of CPU time.
