These models are used by nltk.sent_tokenize to split a string into a list of sentences.. A brief tutorial on sentence and word segmentation (aka tokenization) can be found in Chapter 3.8 of the NLTK book..

Other pickled data installable with nltk.download (e.g. POS taggers) also has this issue. We can't just apply this patch to NLTK because "encoding" parameter is Python3-only. NLTK module has many datasets available that you need to download to use. More technically it is called corpus. Some of the examples are stopwords, gutenberg, framenet_v15, large_grammarsand so on.

NLTK Word Tokenizer: nltk.word_tokenize() The usage of these methods is provided below.

For instance, this model knows that a name may contain a period (like “S.

I think the reason is that pickled Punkt tokenizer available in nltk_data was trained on byte strings, and implicit byte strings fail under Python 3.x. Other pickled data installable with nltk.download (e.g. POS taggers) also has this issue. We can't just apply this patch to NLTK because "encoding" parameter is Python3-only.

However, you will first need to download the punkt resource. Run the NLTK is the tool which we'll be using to do much of the text processing in this ways of tokenising text and today we will use NLTK's in-built punkt tokeniser by nltk.tokenize.punkt module. This instance has already been trained and works well for many European languages. So it knows what punctuation and characters Training a Punkt Sentence Tokenizer. Let's first build a corpus to train our tokenizer on. We'll use stuff available in NLTK: 5 Oct 2019 Resource punkt not found. Please use the NLTK Downloader to obtain the resource: import nltk nltk.download('punkt').
