# RomanUrdu-NLP-Sentiment-Corpus
**Largest Open-Source Roman Urdu Sentiment Dataset with Slang Robustness**

---

## Overview

This repository presents the largest publicly available Roman Urdu sentiment analysis dataset, containing **134,052 labeled text samples** collected from chats and social media platforms. The dataset is designed to be:

- Robust to slang and informal Roman Urdu  
- High-quality through LLM-assisted labeling and human validation  
- Balanced across sentiment classes  
- Suitable for research and real-world NLP applications  

This dataset supports research in:

- Sentiment Analysis  
- Low-resource language NLP  
- Code-mixed and slang-aware text modeling  
- Social media opinion mining  

---

## Dataset Design Goals

The dataset was created with the following objectives:

1. Robustness to slang, abbreviations, and spelling variations  
2. Large-scale corpus for deep learning models  
3. High annotation quality through hybrid labeling  
4. Open-source accessibility under Apache 2.0  
5. Future extensibility with emotion labels

## Dataset Structure

Each row contains two attributes:

| Column | Description |
|--------|-------------|
| `message` | Roman Urdu text |
| `label` | Sentiment class (`Positive`, `Neutral`, `Negative`) |

---

## Dataset Statistics

### General Statistics

- Total samples: **134,052**  
- Unique messages: **109,409**  
- Most frequent message: `"Good"` (24 occurrences)  
- Labels: **3** (Positive, Neutral, Negative)

---

### Class Distribution

| Label | Percentage |
|-------|------------|
| Positive | 28% |
| Neutral | 32% |
| Negative | 40% |

This distribution reflects real-world social media sentiment skew.

## Message Length Statistics

### Word Length (per message)

```python
count    134052
mean        13.55 words
std         19.46
min          0
25%          5
50%          9
75%         16
max       3212
```

### Character Length (per message)

```python
count    134052
mean        66.62 chars
std        102.15
min          1
25%         22
50%         41
75%         81
max      19074
```

### Average Word Length by Label

| Label    | Avg Words |
| -------- | --------- |
| Negative | 18.05     |
| Positive | 13.68     |
| Neutral  | 7.87      |

Negative samples tend to be longer and more expressive, while neutral messages are shorter and concise.

## Annotation Methodology

The dataset was created in two major phases:

### Phase 1: Initial Dataset (99K Samples)

- Labeled using LLM-assisted annotation

- Verified by human annotators and validators

- Released previously in the form of embeddings

- Used to train the baseline model:
    `Khubaib01/roman-urdu-sentiment-xlm-r`

  > - Read the paper here: [Paper](https://doi.org/10.5281/zenodo.18080524)

### Phase 2: Extended Dataset (134K Samples)

- Additional samples labeled using the trained model

- All newly labeled samples validated by human reviewers

Focused on including:

- Slang

- Informal expressions

- Local dialect usage

- Social media language patterns

This hybrid annotation pipeline ensures:

- Scalability

- Consistency

- High label reliability

## Benchmark Model

A sentiment classification model trained on the initial 99k dataset:

**Model Name:**
`Khubaib01/roman-urdu-sentiment-xlm-r`

**Performance:**

- Achieved 84% accuracy

- Ranked highest among available Roman Urdu sentiment models on HuggingFace at time of evaluation

- Benchmarked against multiple multilingual and Roman Urdu models

This model was also used to assist labeling for the extended dataset.

## Slang & Robustness Focus

Unlike many clean benchmark datasets, this dataset includes:

- Local slang

- Abbreviations (e.g., "bkl", "yr", "bhai", "scene off")

- Misspellings

- Mixed English + Roman Urdu

- Informal sentence structures

This makes the dataset suitable for:

- Real-world deployment

- Chatbots

- Social media analysis

- Low-resource language research

## Future Work

Planned extensions include:

- Emotion labels (anger, joy, sadness, fear, etc.)

- Multi-label emotion classification

- Offensive and toxicity detection

- Language normalization benchmarks
