Constructor Details

#initialize(grammar = ENGLISH_PCFG_MODEL, options = []) ⇒ LexicalizedParser

Create the parser given a grammar and options. The grammar argument is a path to a grammar file. This path may contain the string $(ROOT), which will be replaced with the root directory of the Stanford Parser. By default, an English PCFG grammar is loaded.

The options argument is a list of string arguments as they would appear on a command line. See the documentaion of edu.stanford.nlp.parser.lexparser.Options.setOptions for more details.

# File 'lib/stanfordparser.rb', line 149

def initialize(grammar = ENGLISH_PCFG_MODEL, options = [])
  @grammar = Pathname.new(grammar.gsub(/\$\(ROOT\)/, ROOT))
  super("edu.stanford.nlp.parser.lexparser.LexicalizedParser", @grammar.to_s)
  @java_object.setOptionFlags(options)
end
