This metric module is designed to solve the task of creating a world model and corresponding keys,
given a formula and whether that formula needs to be satiesfied. Please read my M.Sc. thesis for details.
In summary, my compute function behaves like it usually does,
but in order to be able to compare references and predictions, I need to
pass the predictions to a parser. Hence, why I rewrote just the compute function.
"""
# TODO: Add description of the arguments of the module here
_KWARGS_DESCRIPTION = """
Calculates how good are predictions given some references, using certain scores
Args:
predictions: list of predictions to score. Each predictions
should be a string with tokens separated by spaces.
references: list of references, one for each prediction. Each
reference should be a string with tokens separated by spaces.
formulas: list of strings, needed for the parser to decide
whether the overall construction is valid (satisfied or unsatisfied).
Returns:
accuracy: description of the first score,
another_score: description of the second score,
Examples:
Examples should be written in doctest format, and should illustrate how
to use the function.
>>> my_new_module = evaluate.load("my_new_module")
>>> results = my_new_module.compute(references=[0, 1], predictions=[0, 1])
