Apply the Snowball Algorithm on Input and unify the result
(an atom) with Stem.
The implementation maintains a cache of stemmers for each thread
that accesses snowball/3, providing high-perfomance and
thread-safety without locking.
- Arguments:
-
| Algorithm | - is the (english) name for desired algorithm
or an 2 or 3 letter ISO 639 language code. |
| Input | - is the word to be stemmed. It is either an
atom, string or list of chars/codes. The library
accepts Unicode characters. Input must be
lowercase. See downcase_atom/2. |
- Errors
- -
domain_error(snowball_algorithm, Algorithm) - -
type_error(atom, Algorithm) - -
type_error(text, Input)
