How to Perform Sentiment Analysis in Spanish with Electricidad

January 11, 2021

In the world of Natural Language Processing (NLP), sentiment analysis is an important capability that allows us to gauge the feelings expressed in texts—whether they are positive, negative, or neutral. In this article, we’ll explore how to fine-tune and utilize the Electricidad model, specifically designed for Spanish sentiment analysis using the muchocine dataset.

Setting Up Your Environment

To get started, you need to install the necessary libraries and download the model. Here’s how to do it:

python
pip install -q transformers

Loading the Model and Tokenizer

Once the library is installed, you can load the model and tokenizer using the following code:

python
from transformers import AutoModelForSequenceClassification, AutoTokenizer

CHKPT = "mrm8488/electricidad-small-finetuned-muchocine"
model = AutoModelForSequenceClassification.from_pretrained(CHKPT)
tokenizer = AutoTokenizer.from_pretrained(CHKPT)

Think of the model as a chef and the tokenizer as the sous-chef. The model (chef) is responsible for the main cooking while the tokenizer (sous-chef) prepares the ingredients, transforming raw texts into a format that the chef can work with efficiently.

Using Pipelines for Sentiment Analysis

Transformers library provides a streamlined pipeline to easily conduct sentiment analysis:

python
from transformers import pipeline

classifier = pipeline("sentiment-analysis", model=model, tokenizer=tokenizer)

Evaluating Sentences

Now that your classifier is ready, you can evaluate the sentiment of various sentences. Here are a few examples:

python
classifier("Es una obra maestra. Brillante.")
classifier("Es una película muy buena.")
classifier("Una buena película, sin más.")
classifier("Esperaba mucho más.")
classifier("He tirado el dinero. Una basura. Vergonzoso.")

Each of these statements can be ranked from 1 to 5 stars, with 1 being the worst sentiment and 5 being the best. This ranking system helps to quickly understand public sentiment toward the movie in review.

Troubleshooting Common Issues

If you encounter issues while running the code, here are some troubleshooting tips:

Check if you have the latest version of `transformers`. Update the package if necessary.
Ensure your internet connection is stable, as downloading the model and tokenizer requires multiple connections.
If you experience import errors, verify that your Python environment is correctly configured.
