Method Details

init(self, boxer_drs_interpreter=None, elimeq=False, bin_dir=None, verbose=False)
(Constructor)

source code

Parameters:

boxer_drs_interpreter - A class that converts from the AbstractBoxerDrs object hierarchy to a different object. The default is NltkDrtBoxerDrsInterpreter, which converts to the NLTK DRT hierarchy.
elimeq - When set to true, Boxer removes all equalities from the DRSs and discourse referents standing in the equality relation are unified, but only if this can be done in a meaning-preserving manner.

Overrides: object.__init__

interpret(self, input, discourse_id=None, question=False, verbose=False)

source code

Use Boxer to give a first order representation.

Parameters:

input - str Input sentence to parse
occur_index - boolean Should predicates be occurrence indexed?
discourse_id - str An identifier to be inserted to each occurrence-indexed predicate.

Returns:

drt.AbstractDrs

interpret_multisentence(self, input, discourse_id=None, question=False, verbose=False)

source code

Use Boxer to give a first order representation.

Parameters:

input - list of str Input sentences to parse as a single discourse
occur_index - boolean Should predicates be occurrence indexed?
discourse_id - str An identifier to be inserted to each occurrence-indexed predicate.

Returns:

drt.AbstractDrs

batch_interpret(self, inputs, discourse_ids=None, question=False, verbose=False)

source code

Use Boxer to give a first order representation.

Parameters:

inputs - list of str Input sentences to parse as individual discourses
occur_index - boolean Should predicates be occurrence indexed?
discourse_ids - list of str Identifiers to be inserted to each occurrence-indexed predicate.

Returns:

list of drt.AbstractDrs

batch_interpret_multisentence(self, inputs, discourse_ids=None, question=False, verbose=False)

source code

Use Boxer to give a first order representation.

Parameters:

inputs - list of list of str Input discourses to parse
occur_index - boolean Should predicates be occurrence indexed?
discourse_ids - list of str Identifiers to be inserted to each occurrence-indexed predicate.

Returns:

drt.AbstractDrs

_call_candc(self, inputs, discourse_ids, question, filename, verbose=False)

source code

Call the candc binary with the given input.

Parameters:

inputs - list of list of str Input discourses to parse
discourse_ids - list of str Identifiers to be inserted to each occurrence-indexed predicate.
filename - str A filename for the output file

Returns:

stdout

_call_boxer(self, filename, verbose=False)

source code

Call the boxer binary with the given input.

Parameters:

filename - str A filename for the input file

Returns:

stdout

_call(self, input_str, binary, args=`[]`, verbose=False)

source code

Call the binary with the given input.

Parameters:

input_str - A string whose contents are used as stdin.
binary - The location of the binary to call
args - A list of command-line arguments.

Returns:

stdout
