MrBERT-nos-gl-sentiment: Sentiment Analysis for Galician

Fine-tuned version of MrBERT-nos-gl for three-class sentiment analysis (positive / neutral / negative) in Galician. Developed as part of Proxecto Nós, an initiative to build language technology for the Galician language.

Model Details

Property	Value
Base model	proxectonos/MrBERT-nos-gl
Task	Text classification (sentiment analysis)
Language	Galician (gl)
License	Apache 2.0
Labels	POSITIVE, NEUTRAL, NEGATIVE

Training Data

Fine-tuned on proxectonos/sentimento-gl, a Galician sentiment dataset.

Usage

Installation

pip install transformers torch

Quick start

from transformers import pipeline, AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("proxectonos/MrBERT-nos-gl-sentiment")
model = AutoModelForSequenceClassification.from_pretrained("proxectonos/MrBERT-nos-gl-sentiment")
sentiment_analyzer = pipeline(
    "text-classification",
    model=model,
    tokenizer=tokenizer,
)

text = "A película pareceume moi interesante e emotiva."
results = sentiment_analyzer(text, top_k=3)

for i, result in enumerate(sorted(results, key=lambda x: x['score'], reverse=True)):
    print(f"{i+1}. {result['label']:<20} {result['score']*100:.1f}%")

Example output

1. POSITIVE             91.3%
2. NEUTRAL               6.2%
3. NEGATIVE              2.5%

Interactive CLI (optional)

For interactive exploration from the command line:

while True:
    text = input("Enter text to analyze sentiment: ").strip()
    if text.lower() in ["quit", "exit", "q"]:
        break
    results = sentiment_analyzer(text, top_k=3)
    for i, r in enumerate(sorted(results, key=lambda x: x['score'], reverse=True)):
        bar = "█" * int(r['score'] * 20)
        print(f"  {i+1}. {r['label']:<20} {r['score']*100:5.1f}%  {bar}")
