English Sarcasm Detector

English Sarcasm Detector is a text classification model built to detect sarcasm from news article titles. It is fine-tuned on bert-base-uncased and the training data consists of ready-made dataset available on Kaggle.

Labels: 0 -> Not Sarcastic; 1 -> Sarcastic

Source Data

Datasets:

English language data: Kaggle: News Headlines Dataset For Sarcasm Detection.

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/english-sarcasm-detector"

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

text = "CIA Realizes It's Been Using Black Highlighters All These Years."
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': 1, 'confidence': 0.9337034225463867}
