## Quality Filtering Criteria

This dataset was curated with the following quality filters:

- Minimum question score threshold of 93
- Only includes questions with accepted or highly-voted answers
- Covers diverse programming topics and languages
- Excludes closed, duplicate, or low-quality posts

## Use Cases

This dataset is ideal for:

- **LLM Fine-tuning**: Train models to answer programming questions
- **Code Understanding**: Build systems that comprehend code-related queries
- **Information Retrieval**: Develop semantic search for technical documentation
- **Question Answering Systems**: Create domain-specific QA models
- **Educational Tools**: Power programming tutors and learning assistants
- **Text Classification**: Train models to categorize technical content

## Loading the Dataset

### Python (Pandas)

```python
import pandas as pd

# Load CSV
df = pd.read_csv('50K_stackoverflow.csv')

# Load Parquet (recommended for performance)
df = pd.read_parquet('50K_stackoverflow.parquet')
```

### Python (JSONL)

```python
import json

data = []
with open('50K_stackoverflow.jsonl', 'r') as f:
    for line in f:
        data.append(json.loads(line))
```

### Hugging Face Datasets

```python
from datasets import load_dataset

dataset = load_dataset('Omarrran/50K_stackoverflow_qna_dataset_by_hnm')
```

## File Format Recommendations

| Use Case | Recommended Format |
|----------|-------------------|
| Data Analysis | Parquet |
| Machine Learning | Parquet |
| Streaming/Processing | JSONL |
| Spreadsheet Tools | CSV |
| Storage Efficiency | Parquet (52% smaller than CSV) |
