This is a fine-tuned version of MoritzLaurer/deberta-v3-base-zeroshot-v1.1-all-33 on a custom Turkish dataset for zero-shot classification tasks. The model is trained to classify textual inputs as entailment or not_entailment for multiple categories like Memnuniyet (user satisfaction), Şikayet (complaints), and others.

The model leverages the strong multilingual capabilities of DeBERTa-v3-base and is designed for fine-grained understanding of customer feedback and textual sentiment in the Turkish language.

Model Details

Model Description

Developed by: yeniguno
Model type: Natural Language Inference (NLI) / Zero-shot classification
Language(s) (NLP): Turkish
License: MIT
Finetuned from model: MoritzLaurer/deberta-v3-base-zeroshot-v1.1-all-33

Uses

Analyzing customer feedback in Turkish.
Zero-shot classification of user reviews into predefined categories.

Bias, Risks, and Limitations

The model is trained exclusively on Turkish data. It may not perform well for other languages. Biases from the training data (e.g., overrepresentation of certain categories) may affect performance. High reliance on proper hypothesis construction; ambiguous or irrelevant hypotheses may lead to suboptimal predictions.

How to Get Started with the Model

You can easily use the model for inference with the Hugging Face pipeline functionality. Below is an example to classify the review:

python

from transformers import pipeline

CANDIDATE_LABELS = [
    "Uygulama Performansı", 
    "Kullanıcı Arayüzü", 
    "Güncellemeler", 
    "Hata ve çökme", 
    "Reklam",
    "Satın Alımlar", 
    "Müşteri Desteği", 
    "Abonelik",	
    "Memnuniyet", 
    "Özellikler",
    "Şikayet"
    ]

# Load the pipeline
classifier = pipeline("zero-shot-classification", model="yeniguno/nli-zero-shot-reviews-MiniLM-turkish-v1")

text = "ChatGPT'nin abonelik ücreti çok yüksek ve müşteri desteği hiç yok, sorun yaşadığınızda yardım alabileceğiniz kimseyi bulamıyorsunuz."

response = classifier(text, CANDIDATE_LABELS, multi_label=True)

for label, score in zip(response["labels"], response["scores"]):
    print(f"{label}: {score:.3f}")

Training Details

Training Data
