NLTK has various libraries and packages for NLP( Natural Language Processing ). It has more than 50 corpora and lexical resources for processing and analyzes texts like classification, tokenization, stemming, tagging e.t.c. Some of them are Punkt Tokenizer Models, Web Text Corpus, WordNet, SentiWordNet.

word_tokenize() returns a list of strings (words) which can be stored as tokens. 2012-01-17 2020-12-24 sent_tokenize uses an instance of PunktSentenceTokenizer from the nltk. tokenize.punkt module. This instance has already been trained on and works well for many European languages. So it knows what punctuation and characters mark the end of a sentence and the beginning of a new sentence. NLTK has been called a wonderful tool for teaching and working in computational linguistics using Python and an amazing library to play with natural language. By data scientists, for data scientists.

''' Before using a tokenizer in NLTK, you need to download an additional resource, punkt. The punkt module is a pre-trained model that helps you tokenize words and sentences. For instance, this model knows that a name may contain a period (like “S. Daityari”) and the presence of this period in a sentence does not necessarily end it. You can use the -d flag to specify a different location (but if you do this, be sure to set the NLTK_DATA environment variable accordingly).

NLTK module has many datasets available that you need to download to use.

2020-05-08 NLTK provides a PunktSentenceTokenizer class that you can train on raw text to produce a custom sentence tokenizer. You can get raw text either by reading in a file, or from an NLTK corpus using the raw() method.
