How to tokenize text data using HuggingFace tokenizer?

Published on Aug. 22, 2023, 12:19 p.m.

To tokenize text data using the HuggingFace tokenizer, you can use the tokenizer.encode or tokenizer.encode_plus methods, which take a string of text as input and return a list of integers representing the tokenized input.

Here’s an example of how to use the tokenizer:

from transformers import AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("bert-base-cased")

text = "Hello, world! This is some text to tokenize."
encoded_text = tokenizer.encode(text)

In this example, we’ve used the AutoTokenizer class to load the pre-trained tokenizer for BERT. We’ve then used the encode method to tokenize the input text.

You may want to experiment with different tokenizer options such as truncation, padding, and setting special tokens to achieve the best performance for your particular NLP task.

Once you have tokenized your text data, you can use the resulting integer sequences as input to a transformer model in HuggingFace Transformers.
