NLP Tokenization Tools Tutorial

Tokenization is a fundamental step in natural language processing (NLP), where text is split into smaller units called tokens, such as words, phrases, or subwords. This tutorial will introduce you to some popular tokenization tools available in the NLP community.

Common Tokenization Tools

Here's a list of commonly used tokenization tools:

• NLTK Tokenizer: A Python library for working with human language data. It includes a tokenizer that can handle a variety of tokenization tasks.

  • NLTK Tokenizer Documentation

• spaCy Tokenizer: spaCy is a powerful and easy-to-use library for NLP. It provides a tokenizer that is efficient and supports multiple languages.

  • spaCy Tokenizer

• Stanford CoreNLP Tokenizer: Stanford CoreNLP is a suite of NLP tools that includes a tokenizer. It is known for its accuracy and support for many languages.

  • Stanford CoreNLP Tokenizer

• Hugging Face Tokenizers: Hugging Face provides a set of tokenizers for different models, including BERT and GPT. They are designed to work well with their respective models.

  • Hugging Face Tokenizers

Example Usage

Let's see how to use the spaCy tokenizer to tokenize a sentence:

import spacy

nlp = spacy.load("en_core_web_sm")
text = "Natural language processing is fascinating."
doc = nlp(text)
tokens = [token.text for token in doc]

print(tokens)

This will output:

['Natural', 'language', 'processing', 'is', 'fascinating', '.']
