Bases: Exception

arsenal.nlp.data.ptb.main()

arsenal.nlp.data.ptb.pformat(t)

Pretty print tree as a tabbified s-expression.

arsenal.nlp.data.ptb.pprint(t, out=<built-in method write of _io.TextIOWrapper object>)

Pretty print tree as a tabbified s-expression.

arsenal.nlp.data.ptb.print_parse(t, out=<built-in method write of _io.TextIOWrapper object>)

Print parse formatted as an s-expression.

arsenal.nlp.data.ptb.sexpr(s, add_root=True)

Example usage:

>>> sexpr('(S (NP Papa) (VP (V ate) (NP (Det the) (N caviar))))')
['S', ['NP', 'Papa'], ['VP', ['V', 'ate'], ['NP', ['Det', 'the'], ['N', 'caviar']]]]

TO match the Penn tree bank we add a ROOT symbol in the following case

>>> sexpr('((S (NP Papa) (VP (V ate) (NP (Det the) (N caviar)))))')
['ROOT', ['S', ['NP', 'Papa'], ['VP', ['V', 'ate'], ['NP', ['Det', 'the'], ['N', 'caviar']]]]]
