ABSA-Turkish-bert-based-uncased

Aspect Based Sentiment Analysis with Turkish 🇹🇷 Data

<!-- Provide a quick summary of what the model is/does. -->

This model performs Aspect-Based Sentiment Analysis (ABSA) 🚀 for Turkish text. It predicts sentiment polarity (Positive, Neutral, Negative) towards specific aspects within a given sentence.

Model Details

Model Description

<!-- Provide a longer summary of what this model is. -->

This model is fine-tuned from the dbmdz/bert-base-turkish-uncased pretrained BERT model. It is trained on the Turkish-ABSA-Wsynthetic dataset, which contains Turkish restaurant reviews annotated with aspect-based sentiments. The model is capable of identifying the sentiment polarity for specific aspects (e.g., "servis," "fiyatlar") mentioned in Turkish sentences.

• Developed by: Sengil
• Language(s): Turkish 🇹🇷

• Finetuned from model: dbmdz/bert-base-turkish-uncased
• Number of Labels: 3 (Negative, Neutral, Positive)

Uses

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->

Direct Use

This model can be used directly for analyzing aspect-specific sentiment in Turkish text, especially in domains like restaurant reviews.

Downstream Use

It can be fine-tuned for similar tasks in different domains (e.g., e-commerce, hotel reviews, or customer feedback analysis).

Out-of-Scope Use

• Not suitable for tasks unrelated to sentiment analysis or Turkish language.
• May not perform well on datasets with significantly different domain-specific vocabulary.

---

Limitations

• May struggle with rare or ambiguous aspects not covered in the training data.
• May exhibit biases present in the training dataset.

How to Get Started with the Model

<!-- This section provides code examples and links to further documentation. -->

!pip install -U transformers

Use the code below to get started with the model:

from transformers import AutoTokenizer, AutoModelForSequenceClassification

# Load the model and tokenizer
tokenizer = AutoTokenizer.from_pretrained("Sengil/ABSA-Turkish-bert-based-uncased")
model = AutoModelForSequenceClassification.from_pretrained("Sengil/ABSA-Turkish-bert-based-uncased")

# Example inference
text = "Servis çok yavaştı ama yemekler lezzetliydi."
aspect = "servis"
formatted_text = f"[CLS] {text} [SEP] {aspect} [SEP]"

inputs = tokenizer(formatted_text, return_tensors="pt", padding="max_length", truncation=True, max_length=128)
outputs = model(**inputs)
predicted_class = outputs.logits.argmax(dim=1).item()

# Map prediction to label
labels = {0: "Negative", 1: "Neutral", 2: "Positive"}
print(f"Sentiment for '{aspect}': {labels[predicted_class]}")
