This difference is a good demonstration of why it can be useful to train your own sentence tokenizer, especially when your text isn't in the typical paragraph-sentence structure. Python Program import nltk # nltk tokenizer requires punkt package # download if not downloaded or not up-to-date nltk.download('punkt') # input text sentence Punkt Sentence Tokenizer. This tokenizer divides a text into a list of sentences, by using an unsupervised algorithm to build a model for abbreviation words, TXT. r""". Punkt Sentence Tokenizer.

It is based on the assumption that a large number of ambiguities in the determination of sentence boundaries can be eliminated once abbreviations have been identiﬁed. The full description of the algorithm is presented in the following academic paper: PunktSentenceTokenizer is an sentence boundary detection algorithm that must be trained to be used. NLTK already includes a pre-trained version of the PunktSentenceTokenizer. So if you use initialize the tokenizer without any arguments, it will default to the pre-trained version: The punkt.zip file contains pre-trained Punkt sentence tokenizer (Kiss and Strunk, 2006) models that detect sentence boundaries. These models are used by nltk.sent_tokenize to split a string into a list of sentences.

Punkt tokenizer uses an unsupervised algorithm, meaning you just train it with regular text. A sentence tokenizer which uses an unsupervised algorithm to build a model for abbreviation words, collocations, and words that start sentences; and then uses that model to find sentence boundaries. This approach has been shown to work well for many European languages. Here are the examples of the python api nltk.tokenize.punkt.PunktSentenceTokenizer taken from open source projects.
