# Small Knowledge Graphs (small-kgs)

A collection of small knowledge graphs in multiple formats for graph ML research and development.

## Dataset Structure

This dataset contains knowledge graphs in three formats:

### graph-std
Compressed Sparse Row (CSR) graph format with parquet files containing:
- Node data (persons, organizations, events, concepts, places, knowledge graphs)
- Edge indices and indirection pointers
- Node/edge type mappings
- Schema definition

### duckdb
DuckDB database format for efficient analytical queries on graph data.

### lbdb
LadybugDB format for graph database operations using the LadybugDB embedded graph database.

## Usage

```python
from datasets import load_dataset

# Load graph-std version
dataset = load_dataset("ladybugdb/small-kgs", name="graph-std")

# Load duckdb version  
dataset = load_dataset("ladybugdb/small-kgs", name="duckdb")

# Load lbdb version
dataset = load_dataset("ladybugdb/small-kgs", name="lbdb")
```
