categories.

LauzHack is an annual 24-hour hackathon hosted at EPFL (École Polytechnique
Fédérale de Lausanne) in Lausanne, Switzerland, bringing together students and
hackers to create innovative solutions within a short timeframe.

| `hackathon_name`     | string       | Name of the hackathon event                               |
| `hackathon_year`     | int64        | Year the hackathon took place                             |
| `hackathon_location` | string       | Location of the hackathon                                 |

### Data Splits

The dataset is available in multiple configurations (subsets) for different
years:

- **lauzhack-2023**: 67 projects from LauzHack 2023
- **lauzhack-2024**: 79 projects from LauzHack 2024
- **lauzhack-2025**: 67 projects from LauzHack 2025

## Usage

### Loading the Dataset

```python
from datasets import load_dataset

# Load a specific year's data
dataset = load_dataset("username/lauzhack-projects", "lauzhack-2025")

# Access the training split
projects = dataset["train"]

# View a sample project
print(projects[0])
```

### Example Project

```python
{
    "id": 1,
    "title": "AI-Powered Study Assistant",
    "description": "An AI chatbot designed to help students with course material...",
    "url": "https://devpost.com/software/...",
    "team": ["Alice Dupont", "Bob Mueller"],
    "awards": ["Best Use of AI"],
    "categories": ["Machine Learning", "Education Tech", "Open Science"],
    "hackathon_name": "LauzHack 2025",
    "hackathon_year": 2025,
    "hackathon_location": "EPFL, Lausanne, Switzerland"
}
```

## Dataset Creation

### Data Collection

Projects were extracted from the LauzHack official website using web scraping
techniques. The data includes all publicly submitted projects from past events.

### Data Processing

- Projects are cleaned and deduplicated
- Team members and awards are extracted into list structures
- URLs are validated and normalized
- Text fields are preserved in their original language

## Considerations for Using the Data

### Intended Use

- **Academic Research**: Student hackathon trends, innovation patterns
- **Career Analysis**: Skills and technologies used in recent projects
- **Event Organization**: Understanding project scope and diversity
- **Machine Learning**: Training models for project classification and
  recommendation

### Known Limitations

- Only includes publicly available project data
- Some projects may have incomplete information (missing descriptions, URLs, or
  award data)
- Team member names as submitted (may include pseudonyms)
- Hackathon location fixed as EPFL; some projects may have had distributed teams

### Ethical Considerations

- All data is from public hackathon submissions
- Licensed under CC-BY 4.0 (attribution required)
- No personal information beyond team member names included
- Respects original project creators' intellectual property
