How to Use the XLMRoberta-Based Classifier for Text Formality Detection

Jun 7, 2024 | Educational

Text analysis applications are crucial in the modern language processing landscape, especially when it comes to understanding the nuances of formality in communication. This guide will walk you through using an XLMRoberta-based classifier tailored for text formality classification. Whether you’re determining the tone of a user message or refining your AI text generation, this tool fits seamlessly into your repertoire.

Getting Started

This section highlights how to deploy the XLMRoberta-based classifier effectively.

Step 1: Install Required Libraries

  • You’ll need the transformers library to access the XLMRoberta model. Install it using pip if you haven’t already:
  • pip install transformers

Step 2: Load the Tokenizer and Model

  • Initialize the tokenizer and model for formality classification:
  • from transformers import XLMRobertaTokenizerFast, XLMRobertaForSequenceClassification
    
    tokenizer = XLMRobertaTokenizerFast.from_pretrained('s-nlp/xlmr_formality_classifier')
    model = XLMRobertaForSequenceClassification.from_pretrained('s-nlp/xlmr_formality_classifier')

Step 3: Prepare Your Text Data

  • Specify the texts you’d like to classify:
  • texts = [
        "I like you. I love you",
        "Hey, what's up?",
        "Siema, co porabiasz?",
        "I feel deep regret and sadness about the situation in international politics.",
    ]

Step 4: Tokenization of Texts

  • Convert your texts into a format digestible for the model:
  • encoding = tokenizer(
        texts,
        add_special_tokens=True,
        return_token_type_ids=True,
        truncation=True,
        padding="max_length",
        return_tensors="pt",
    )

Step 5: Make Predictions

  • Run inference to get the scores for formality:
  • output = model(**encoding)
    
    id2formality = {0: "formal", 1: "informal"}
    formality_scores = [
        {id2formality[idx]: score for idx, score in enumerate(text_scores.tolist())}
        for text_scores in output.logits.softmax(dim=1)
    ]

Understanding the Output

The output will reveal the likelihood of formality for each text compared to the informal tone. The scores will look something like this:

[{'formal': 0.9932, 'informal': 0.0068}, {'formal': 0.8808, 'informal': 0.1192}, ...]

Analogy of the Process: A Language Tailor

Imagine your sentences as suits and dresses woven with different fabrics. Some are formal silk gowns, while others are casual cotton outfits. Just as a tailor selects specific materials to fashion each garment, the XLMRoberta model segregates your text based on its tonal fabric. When you feed these texts into the model, it’s akin to an expert tailor analyzing which fabric best represents formality—silk or cotton. The numerical scores reflect how well each fabric (text) aligns with expected styles (formal vs. informal).

Troubleshooting

If you encounter any issues with the model or implementation:

  • Issue: Model does not load or throws an error.
    Solution: Ensure that you have a stable internet connection and the latest version of the transformers library. Running pip install --upgrade transformers might help.
  • Issue: Unexpected output or errors during inference.
    Solution: Check your input texts for any unusual characters or lengths. Ensure that your texts are formatted correctly and within the model’s input length limits.
