Spanish BERT2BERT: A Deep Dive into Question Generation

May 4, 2023

Welcome to our exploration of generating questions using fine-tuned Spanish BERT2BERT models! Today, we will walk through the process of using this powerful natural language processing (NLP) tool, specifically fine-tuned on the SQuAD (Spanish) dataset.

What is BERT2BERT?

BERT2BERT is an advancement in the BERT (Bidirectional Encoder Representations from Transformers) framework that enables models to understand and generate human-like text. In our case, we have a model trained to generate questions based on a given input in Spanish.

Setting Up Your Environment

Before we dive into the coding aspect, ensure you have the necessary installations:

Python 3.6 or later
Transformers library from Hugging Face
PyTorch or TensorFlow (depending on your preference)

How to Generate Questions

Generating questions using the fine-tuned model is like having a curious friend who asks different questions based on snippets of information you provide. Let’s explore the steps you need to follow:

Step 1: Load the Model

You start by loading the fine-tuned Spanish BERT2BERT model. In our analogy, it’s like inviting your curious friend over—the friend needs to know how to ask questions based on various topics!

from transformers import T5Tokenizer, T5ForConditionalGeneration

# Load the model and tokenizer
tokenizer = T5Tokenizer.from_pretrained("bert2bert-spanish-squad")
model = T5ForConditionalGeneration.from_pretrained("bert2bert-spanish-squad")

Step 2: Prepare Your Input

Now, let’s give your friend some context. For instance, if you tell your friend that “Manuel vive en Murcia, España”, our model will understand this input and generate questions like “¿Dónde vive Manuel?”

# Input text
input_text = "Manuel vive en Murcia, España"
input_ids = tokenizer.encode(input_text, return_tensors="pt")

Step 3: Generate the Questions

Finally, it’s time for your friend to ask questions! Just like your friend might come up with multiple questions based on the information given, the model will do likewise.

# Generate questions
outputs = model.generate(input_ids)
question = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(question)

Troubleshooting Ideas

Sometimes, your model might not behave as expected. Here are some troubleshooting tips:

If you encounter a “model not found” error, double-check that you’ve correctly referenced the model name.
In case of poor question generation, ensure that your input sentence is clear and structured properly.
If you face runtime errors, verify your environment configurations, including library versions.
