How to Use Chinese BERT with Whole Word Masking

Mar 1, 2022 | Educational

In recent advancements in natural language processing (NLP), BERT (Bidirectional Encoder Representations from Transformers) has emerged as a powerful model for a variety of language tasks. This blog will guide you through the process of utilizing the Chinese BERT model with Whole Word Masking, designed to significantly enhance Chinese NLP tasks.

What is Whole Word Masking?

Whole Word Masking (WWM) is a technique that improves BERT’s understanding of the context of words in a sentence. Unlike standard masking that randomly masks individual tokens, WWM masks entire words. This helps the model learn to better focus on the relevant parts of the text.

Getting Started with Chinese BERT

To get started, you’ll need to use specific function calls associated with the BERT model. Here’s a simplified version of the process:

Install the necessary libraries and dependencies for your Python environment.
Download the pre-trained Chinese BERT model that utilizes Whole Word Masking from the relevant repository.
Load the model using the appropriate functions designed for this specific BERT variant.

Step-by-Step Instructions

import torch
from transformers import BertTokenizer, BertModel

# Load the tokenizer and model for Chinese BERT with WWM
tokenizer = BertTokenizer.from_pretrained('hfl/chinese-bert-wwm')
model = BertModel.from_pretrained('hfl/chinese-bert-wwm')

# Example text
text = "你好，世界!"  # "Hello, World!" in Chinese
inputs = tokenizer(text, return_tensors='pt')

# Perform a forward pass to get outputs
outputs = model(**inputs)

Analogy for Understanding the Code

Think of the Chinese BERT model as a sophisticated librarian who knows where every book is stored based on topics and subjects. The tokenizer is like a system that categorizes incoming requests (in this case, texts) into easily searchable formats. When you feed the librarian (the model) with a question (the inputs), the librarian quickly processes your request, searches through her vast knowledge (the embeddings), and delivers the best possible information back to you (the outputs).

Troubleshooting Common Issues

If you encounter any issues while working with the Chinese BERT model, consider the following troubleshooting tips:

Model Not Found: Ensure that you have the correct model name and that your internet connection is stable to download the necessary files.
Out of Memory (OOM) Errors: If you are running on limited resources, consider using a smaller batch size when processing your inputs or utilizing a cloud-based solution with greater resources.
Tokenization Errors: Verify that your input text is properly formatted and in the correct language encoding.
