With the rise of digital communication, identifying hate speech in online interactions has become a pressing issue. This tutorial will guide you through the process of utilizing the pretrained K-mHas model with the KoElectra-v3 for binary classification of hate speech.

What You Will Need

• Access to Python and relevant libraries (Transformers, Datasets)
• Hugging Face account for downloading models
• Basic understanding of NLP and model training processes

Step-by-Step Guide

Step 1: Setting Up Environment

First, ensure that you have installed the necessary libraries. You can install them using pip:

pip install transformers datasets

Step 2: Loading the Model and Tokenizer

You’ll need to load the KoElectra model and its tokenizer. The tokenizer will help you prepare your text data for the model.

from transformers import ElectraTokenizer, ElectraForSequenceClassification

tokenizer = ElectraTokenizer.from_pretrained("monologg/korelectra-base-v3-discriminator")
model = ElectraForSequenceClassification.from_pretrained("monologg/korelectra-base-v3-discriminator")

Step 3: Prepare Your Dataset

Now, you’ll need to get the dataset you want to work with. The dataset for Korean hate speech can be accessed via Hugging Face.

from datasets import load_dataset

dataset = load_dataset("jeanleek/kmhas_korean_hate_speech")

Step 4: Understanding Label Maps

In this model, labels are mapped as follows:

• 0: not_hate_speech
• 1: hate_speech

Step 5: Tokenization

With your text ready, it’s time to tokenize the dataset so that your model can understand it:

def tokenize_function(examples):
    return tokenizer(examples['text'], padding="max_length", truncation=True)

tokenized_datasets = dataset.map(tokenize_function, batched=True)

Understanding the Code through Analogy

Think of the process of using the pretrained K-mHas model with KoElectra-v3 like preparing a meal in a new kitchen:

• **Setting Up Environment**: Just like getting all your ingredients and tools ready, here you install the libraries you need.
• **Loading the Model and Tokenizer**: Just as you would take out your recipe book to understand what you’re cooking, you load the model and tokenizer to understand how to analyze hate speech.
• **Preparing the Dataset**: This is akin to gathering your vegetables and proteins, in this case, sourcing the hate speech dataset.
• **Understanding Label Maps**: Like knowing what each spice in your cabinet is used for, this step clarifies what each label means.
• **Tokenization**: Finally, just as you chop and season your ingredients for cooking, you process your text data for the model.

Troubleshooting Tips

If you run into issues while working through the process, here are some troubleshooting ideas:

• Ensure that your libraries are updated.
• Check for correct dataset paths and names.
• Verify that your Python environment is correctly set up.
