Italian Sarcasm Detector

Italian Sarcasm Detector is a text classification model built to detect sarcasm from news article titles. It is fine-tuned on dbmdz/bert-base-italian-uncased and the training data consists of scraped data from Italian non-sarcastic newspaper (Il Giornale) and sarcastic newspaper (Lercio).

<b>Labels</b>: 0 -> Not Sarcastic; 1 -> Sarcastic

Source Data

Scraped data:

• Italian non-sarcastic news from Il Giornale
• Italian sarcastic news from Lercio

Training Dataset

• helinivan/sarcasm_headlines_multilingual

Codebase:

• Git Repo: Official repository

Example of classification

from transformers import AutoModelForSequenceClassification
from transformers import AutoTokenizer
import string

def preprocess_data(text: str) -> str:
   return text.lower().translate(str.maketrans("", "", string.punctuation)).strip()

MODEL_PATH = "helinivan/italian-sarcasm-detector"

tokenizer = AutoTokenizer.from_pretrained(MODEL_PATH)
model = AutoModelForSequenceClassification.from_pretrained(MODEL_PATH)

text = "Gli Usa a un passo dalla recessione"
tokenized_text = tokenizer([preprocess_data(text)], padding=True, truncation=True, max_length=256, return_tensors="pt")
output = model(**tokenized_text)
probs = output.logits.softmax(dim=-1).tolist()[0]
confidence = max(probs)
prediction = probs.index(confidence)
results = {"is_sarcastic": prediction, "confidence": confidence}

Output:

{'is_sarcastic': 0, 'confidence': 0.9965020418167114}
