# ConceptNet 5 (Un-normalized SQLite, 23.6 GB)

This repository contains the complete, un-normalized ConceptNet 5.5 knowledge graph in SQLite format. Unlike the filtered version, this dataset includes **all languages** from the original ConceptNet release.

The database `conceptnet-de-indexed.db` is a 23.6 GB un-normalized SQLite file containing the full knowledge graph with all 28.3 million nodes and 34 million edges across all languages.

## When to Use This Dataset

**Use this dataset if you:**
- Need access to **all languages** in ConceptNet (not just the 11 languages in the normalized version)
- Require the complete, unfiltered knowledge graph
- Are doing cross-linguistic research across many language pairs
- Need the original data structure for compatibility reasons

**Use the normalized version ([cstr/conceptnet-normalized-multi](https://huggingface.co/datasets/cstr/conceptnet-normalized-multi)) if you:**
- Only need 11 specific languages (en, fr, it, de, es, ar, fa, grc, he, la, hbo)
- Want faster query performance (normalized schema with integer keys)
- Need a smaller file size (~1.8 GB vs 23.6 GB)
- Prefer optimized, production-ready data

## Dataset Description

This repository contains the `conceptnet-de-indexed.db` file, a large (23.6 GB) SQLite database of the ConceptNet 5.5 knowledge graph.

- **Nodes**: The `node` table contains 28.3 million nodes from all ConceptNet languages.
- **Edges**: The `edge` table contains 34 million un-filtered edges.
- **Schema**: This database is un-normalized. The `edge` table stores full text URLs for its `start_id`, `end_id`, and `rel_id` columns, resulting in its large size and slower query performance compared to normalized alternatives.
- **Data Quality**: This database contains all original edges, including both high-quality assertions (e.g., `hund IsA raubtier`) and low-quality metadata (e.g., `hund IsA n`).

## Database Schema

### node (28.3M rows)

- `id` (VARCHAR): The full ConceptNet URL (e.g., `/c/en/dog/n`).
- `label` (VARCHAR): The human-readable label.
- `language` (VARCHAR): The language code (e.g., `en`, `de`).
- `sense_label` (VARCHAR): e.g., `n`, `v`.
- `term_id` (VARCHAR): The URL without the POS tag (e.g., `/c/en/dog`).
- ...and other metadata columns.

### relation (50 rows)

- `id` (VARCHAR): The relation URL (e.g., `/r/IsA`).
- `label` (VARCHAR): The relation name (e.g., `IsA`).
- `symmetric` (BOOLEAN): If the relation is symmetric.

### edge (34M rows)

- `id` (VARCHAR): The unique edge URL.
- `rel_id` (VARCHAR): Foreign key (as text URL) to `relation.id`.
- `start_id` (VARCHAR): Foreign key (as text URL) to `node.id`.
- `end_id` (VARCHAR): Foreign key (as text URL) to `node.id`.
- `weight` (FLOAT): The edge weight.
- ...and other metadata columns.

## Example Query

**Note**: Queries on this un-normalized database use text-based keys and may be slower than the normalized version.

```python
import sqlite3
import pandas as pd

DB_PATH = "conceptnet-de-indexed.db"  # Or path from hf_hub_download
conn = sqlite3.connect(f"file:{DB_PATH}?mode=ro", uri=True)

query = """
SELECT
    e.start_id,
    e.end_id,
    e.weight
FROM edge e
WHERE
    e.start_id LIKE 'http://conceptnet.io/c/de/hund%'
    AND e.rel_id = 'http://conceptnet.io/r/IsA'
ORDER BY e.weight DESC
LIMIT 10;
"""

df = pd.read_sql_query(query, conn)
print(df)
conn.close()
```
