A Guide to Using RoBERTa Models for Basque Language Processing

Mar 20, 2022 | Educational

In the realm of natural language processing (NLP), the RoBERTa architecture has made significant strides, particularly for low-resource languages like Basque. If you’ve been keen to contribute to NLP tasks in Basque or explore results from various RoBERTa models, this guide provides a user-friendly overview to get you started.

Overview of the Models

The following RoBERTa models are specifically designed for the Basque language, leveraging different datasets:

  • roberta-eus-euscrawl-base-cased: Trained on the EusCrawl corpus, consisting of 12,528k documents and 423M tokens.
  • roberta-eus-euscrawl-large-cased: A larger variant also trained on EusCrawl.
  • roberta-eus-mC4-base-cased: Derived from the Basque portion of the mC4 dataset.
  • roberta-eus-CC100-base-cased: Based on the Basque portion of the CC100 dataset.

Performance of the Models

These models have been evaluated on five different downstream tasks:

  • Topic Classification
  • Sentiment Analysis
  • Stance Detection
  • Named Entity Recognition (NER)
  • Question Answering

Here’s a summary of their performance metrics:


Model                             Topic class.  Sentiment  Stance det.      NER       QA    Average  
------------------------------------------------------------------------------------------------------
roberta-eus-euscrawl-base-cased           76.2       77.7         57.4     86.8      34.6      66.5   
roberta-eus-euscrawl-large-cased      **77.6**       78.8         62.9  **87.2**  **38.3**  **69.0**  
roberta-eus-mC4-base-cased                75.3   **80.4**         59.1     86.0      35.2      67.2   
roberta-eus-CC100-base-cased              76.2       78.8     **63.4**     85.2      35.8      67.9  

Understanding Performance through Analogy

Think of each RoBERTa model as different chefs using a unique recipe to make the same dish—Basque language processing. Some chefs may excel in certain cuisines (tasks) based on their experience with different ingredients (datasets). The “roberta-eus-euscrawl-large-cased” chef, for instance, slightly outperforms the others, indicating that it has a better understanding of the cuisine due to its larger training dataset. Meanwhile, the “roberta-eus-mC4-base-cased” chef offers a solid recipe but lacks the flair of the best chefs. Each model brings its strengths to the table, making it essential to choose the right one based on your task requirements.

Getting Started

To utilize these models, you can load them using libraries such as Transformers by Hugging Face. Here’s a basic structure to follow:


from transformers import AutoModelForTokenClassification, AutoTokenizer

# Load the model and tokenizer
model_name = "roberta-eus-euscrawl-base-cased"
model = AutoModelForTokenClassification.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

# Prepare the input text
text = "Your Basque text here"
inputs = tokenizer(text, return_tensors="pt")
outputs = model(**inputs)

Troubleshooting Common Issues

As you delve into these models, you may encounter some challenges. Here are some troubleshooting tips:

  • Performance Issues: If you notice that the model is underperforming, ensure that you’re feeding it relevant data. Think of it as giving the chef the right ingredients to work with.
  • Installation Problems: Ensure that all required libraries (e.g., Transformers, PyTorch) are correctly installed. Sometimes it’s a simple matter of missing dependencies, like forgetting to add salt to your dish!
  • Loading Errors: If the model fails to load, check your internet connection or the model name for typos.
