# Kyrgyz Morphological Analysis — BERT

<p align="center">

</p>

## Model Description

A **BERT-based morphological analyzer** for the **Kyrgyz language** — a low-resource Turkic language spoken by ~5 million people. The model performs morphological tagging, predicting grammatical features (POS tags, case, number, tense, etc.) for each token in a sentence.

Kyrgyz is an agglutinative language with rich morphology, making morphological analysis particularly challenging and valuable for downstream NLP tasks.

## Performance

| Model | Accuracy |
|-------|----------|
| **BERT (fine-tuned)** | **~80%** |
| Logistic Regression (baseline) | — |

<!-- 🔧 TODO: Add baseline accuracy if available -->

## Intended Use

| Use Case | Description |
|----------|-------------|
| **Kyrgyz NLP pipeline** | Morphological preprocessing for machine translation, text analysis |
| **Linguistic research** | Studying Kyrgyz grammar and morphological patterns |
| **Education** | Teaching Kyrgyz morphology with automated analysis |
| **Downstream tasks** | Improving NER, dependency parsing, and sentiment analysis for Kyrgyz |

## Training Details

### Dataset

- **Format:** CSV with morphological annotations
- **Train set:** `train_fixed.csv`
- **Test set:** `test_fixed.csv`
- **Tag set:** Defined in `TAG.docx` (morphological tag inventory)

### Architecture

- **Base model:** BERT (fine-tuned for token classification)
- **Custom variant:** `bert_model_variant.py`
- **Baseline:** Logistic Regression (`logistic_regression.ipynb`)

### Framework

- Python 3.10+
- PyTorch / Transformers (HuggingFace)

## How to Use

```python
# Load and run inference
from bert_model_variant import MorphAnalyzer  # adjust import as needed

# Example: Analyze Kyrgyz text
text = "Кыргызстан — кооз өлкө"
# See train.py and dev.py for full inference pipeline
```

<!-- 🔧 TODO: Add a more complete inference example -->

## Why This Matters

Kyrgyz is an **underrepresented language** in NLP. Most morphological analyzers exist only for high-resource languages. This model contributes to:

- Building foundational NLP tools for the Kyrgyz language
- Enabling more complex downstream applications (MT, QA, summarization)
- Preserving and digitizing Kyrgyz linguistic knowledge

## Limitations

- Accuracy of ~80% means roughly 1 in 5 tokens may be mistagged
- Performance may vary across different text domains and registers
- Limited to the morphological tag set defined in `TAG.docx`
