MARBERT for Egyptian Dialect Intent Classification (syplyd-marbert-v1)

This is a text-classification model fine-tuned from the powerful UBC-NLP/MARBERTv2 base model. It is specifically designed to understand and classify user intents written in the Egyptian colloquial Arabic dialect, with a strong focus on e-commerce and customer service contexts.

The model serves as a robust Natural Language Understanding (NLU) engine, capable of powering applications like chatbots, support ticket routers, and voice assistants.

Model Details

Model Description

This model takes a user's query in Egyptian Arabic and classifies it into one of several predefined intents, allowing an application to understand the user's goal and respond appropriately. It was developed through an iterative process of data curation, training, analysis, and refinement to achieve high accuracy and reliability on real-world use cases.

• Model type: bert-for-sequence-classification
• Language(s) (NLP): Arabic (specifically Egyptian Colloquial Dialect)

Uses

Direct Use

This model is intended for direct inference via the Hugging Face pipeline. You can provide a sentence in Egyptian Arabic, and it will return the predicted intent along with a confidence score.

from transformers import pipeline

# Load the model from the Hub
classifier = pipeline("text-classification", model="ShazaAly/syplyd-marbert-1")

# Example Usage
text_1 = "عايز أعرف الأوردر بتاعي هيوصل امتى؟"
result_1 = classifier(text_1)
print(f"'{text_1}' -> {result_1}")
# Expected output: [{'label': 'track_order_status', 'score': 0.99...}]

text_2 = "المنتج ده غالي، فيه بديل أرخص؟"
result_2 = classifier(text_2)
print(f"'{text_2}' -> {result_2}")
# Expected output: [{'label': 'product_alternatives' or 'cheaperYou've done it! You've gone through the entire process from data loading to training, evaluation, and finally, deployment. Excellent work.

Now, let's create the final, professional Model Card for your new model, `syplyd-marbert-v3`, based on all the work and the latest results. This Model Card will be clear, informative, and reflect the high quality of the model you've built.

# MARBERT for Egyptian Dialect Intent Classification (v3)

This is a text-classification model fine-tuned from the powerful **[UBC-NLP/MARBERTv2](https://huggingface.co/UBC-NLP/MARBERTv2)** model. It is specifically designed to understand user intents in the **Egyptian colloquial Arabic dialect**, with a focus on e-commerce and customer service applications.

This model is the result of an iterative development process that involved data cleaning, strategic intent restructuring, and data augmentation to resolve classification ambiguities and improve overall performance.

## Model Details

### Model Description

This model is designed to be the Natural Language Understanding (NLU) core of a chatbot or a request-routing system. It takes a user's query in Egyptian Arabic and classifies it into one of several predefined intents, allowing an application to understand the user's goal and respond appropriately.

- **Developed by:** Shaza Aly
- **Model type:** `bert-for-sequence-classification`
- **Language(s) (NLP):** Arabic (specifically Egyptian Colloquial Dialect)
- **License:** Apache-2.0
- **Finetuned from model:** [UBC-NLP/MARBERTv2](https://huggingface.co/UBC-NLP/MARBERTv2)

## Uses

### Direct Use

This model is intended to be used directly for inference via the Hugging Face `pipeline` or Inference API. You can provide a sentence in Egyptian Arabic, and it will return the predicted intent along with a confidence score.

```python
from transformers import pipeline

# Load the model from the Hub
classifier = pipeline("text-classification", model="ShazaAly/syplyd-marbert-1")

# Example Usage
text_1 = "عايز أعرف الأوردر بتاعي هيوصل امتى؟"
result_1 = classifier(text_1)
print(f"'{text_1}' -> {result_1}")
# Expected output: [{'label': 'track_order_status', 'score': 0.99...}]

text_2 = "المنتج ده غالي، فيه بديل أرخص؟"
result_2 = classifier(text_2)
print(f"'{text_2}' -> {result_2-commerce Chatbots:** Understand user queries to check order status, inquire about products, or ask for suggestions.
- **Ticket Routing Systems:** Automatically classify customer support emails or messages to route them to the correct department (e.g., shipping, billing, technical support).
- **Voice Assistants:** Act as the NLU component for voice-controlled shopping applications that target the Egyptian market.

### Out-of-Scope Use

This model is **not** designed for:
- General conversation or chit-chat.
- Sentiment analysis (detecting if a user is happy or angry).
- Translation or text generation.
- Understanding other Arabic dialects (e.g., Levantine, Gulf) with high accuracy.

## Bias, Risks, and Limitations

This model's knowledge is limited to the intents present in its custom training dataset. It may not recognize or may misclassify intents that are significantly different from the training data.

The primary risk is **misclassification**, which could lead to a poor user experience. It is highly recommended to implement a **confidence threshold** in any production application. If the model's top prediction score is below a certain value (e.g., 0.80), the system should ask for clarification or escalate the query to a human agent.

## Training Details

### Training Data

The model was fine-tuned on a private, custom-built dataset of Egyptian colloquial Arabic sentences. The data was manually curated, cleaned, and labeled to cover a range of common user intents in an e-commerce context. The dataset includes a set of distinct intents such as `order_status`, `shipping_info`, `product_alternatives`, `product_suggestions`, `company_info`, `cancel_order`, and others. The final training set size was approximately 80% of the total cleaned dataset, with the remaining 20% used for testing.

### Training Procedure

The model was trained using the `transformers` library's `Trainer` API. The process involved fine-tuning for 8 epochs with the best model being saved based on the F1-score on the evaluation set.

#### Training Hyperparameters

- **Base Model:** `UBC-NLP/MARBERTv2`
- **Learning Rate:** `2e-5`
- **Train Batch Size:** 16
- **Eval Batch Size:** 16
- **Number of Epochs:** 8
- **Optimizer:** AdamW
- **Warmup Ratio:** 0.1
- **Weight Decay:** 0.01

## Evaluation

The model was evaluated on a held-out test set (20% of the total data).

#### Metrics

The following weighted metrics were used to provide a balanced view of performance across all intents:
- **Accuracy:** The percentage of correctly classified intents.
- **F1-Score:** The harmonic mean of precision and recall.
- **Precision:** Of all the predictions for an intent, how many were correct.
- **Recall:** Of all the actual instances of an intent, how many did the model correctly identify.

### Results

The model achieved the following performance on the final evaluation set:

| Metric    | Score  |
|-----------|--------|
| Accuracy  | 88.5%  |
| F1-Score  | 88.4%  |
| Precision | 90.4%  |
| Recall    | 88.5%  |

These results indicate a strong and well-balanced model that is reliable for its intended use cases.
