Pretrained Punkt Models -- Jan Strunk (New version trained after issues 313 and 514 had been corrected)
|
|
|
|
Most models were prepared using the test corpora from Kiss and Strunk (2006). Additional models have
|
|
been contributed by various people using NLTK for sentence boundary detection.
|
|
|
|
For information about how to use these models, please confer the tokenization HOWTO:

|
|
and chapter 3.8 of the NLTK book:

|

There are pretrained tokenizers for the following languages:
