class matchzoo.preprocessors.units.word_exact_match.WordExactMatch(match:str, to_match:str)

Bases: matchzoo.preprocessors.units.unit.Unit

WordExactUnit Class.

Process unit to get a binary match list of two word index lists. The word index list is the word representation of a text.

Examples

>>> import pandas
>>> input_ = pandas.DataFrame({
...  'text_left':[[1, 2, 3],[4, 5, 7, 9]],
...  'text_right':[[5, 3, 2, 7],[2, 3, 5]]}
... )
>>> left_word_exact_match = WordExactMatch(
...     match='text_left', to_match='text_right'
... )
>>> left_out = input_.apply(left_word_exact_match.transform, axis=1)
>>> left_out[0]
[0, 1, 1]
>>> left_out[1]
[0, 1, 0, 0]
>>> right_word_exact_match = WordExactMatch(
...     match='text_right', to_match='text_left'
... )
>>> right_out = input_.apply(right_word_exact_match.transform, axis=1)
>>> right_out[0]
[0, 1, 1, 0]
>>> right_out[1]
[0, 0, 1]

transform(self, input_)

Transform two word index lists into a binary match list.

Parameters:input – a dataframe include ‘match’ column and ‘to_match’ column. Returns:a binary match result list of two word index lists.
