This standalone program will build a lexicon and a grammar from a collection of Penn Treebank sentences. These can then be used with the ChartParser. Usage:
java edu.stanford.nlp.lexgram.ExtractPTBRules mrg/wsj lex gram [TreeReaderFactory] [startnum] [endnum]
If a TreeReaderFactory class is not specified, a default internal TreeReaderFactory is used. This one will produce grammars compatible with the default factory for the ChartParser. The parameters startnum and endnum serve to specify a number range of Penn Treebank files to train on (e.g., 200 2199).

Parameters:

args - Command line arguments as above

IOException

FileNotFoundException
