Quick Start

from transformers import pipeline

clf = pipeline(
    "text-classification",
    model="salimalsazu/smart-category-detector-v1",
    top_k=5
)

print(clf("Samsung Galaxy S24 Ultra 512GB Mobile"))
print(clf("Dhaka International Book Fair 2026"))
print(clf("Jamboo Burger Tk 220"))

Limitations

• Works best with short text
• Designed primarily for English text
• Mixed-language inputs may reduce accuracy
• Limited to 60 predefined categories
• Unknown categories may be mapped to the closest label

---

Future Improvements

Potential improvements include:

• adding real-world marketplace data
• improving Bangla language support
• increasing spelling robustness
• adding an "unknown" label
• publishing benchmark evaluation metrics
