dtoolkit.accessor.series.textdistance_matrix#

dtoolkit.accessor.series.textdistance_matrix(s: Series, /, other: None | Series = None, method: Callable = None, **kwargs) → DataFrame[source]#

Returns a DataFrame containing the text distances matrix between in s and other.

Parameters:

otherNone or Series, default None: If None, use s.
methodCallable, default None: The method to calculate the distance. The first and second positional parameters will be compared. If None, rapidfuzz.fuzz.ratio(). Recommended use methods in rapidfuzz.fuzz, and rapidfuzz.distance.
**kwargs: Additional keyword arguments passed to method.

Returns:

DataFrame: The values are the text distances.

Raises:

ModuleNotFoundError

If don’t have module named ‘rapidfuzz’.

TypeError

If s is not string dtype.
If other is not string dtype.

Notes

The result of comparing to None or nan value is depended on the method.

Examples

>>> import dtoolkit
>>> import pandas as pd
>>> s = pd.Series(["hello", "world"])
>>> s
0    hello
1    world
dtype: object
>>> s.textdistance_matrix(pd.Series(["hello", "python"]))
       0          1
0  100.0  36.363636
1   20.0  18.181818
