# TCM-MKG Reorganized Graph Export

> 本仓库是对原始 TCM-MKG V1.0 的格式整理与图结构导出，不是原始数据集的官方发布，也不声称拥有底层知识内容。

## Dataset Description

This repository contains a Hugging Face-compatible, reorganized graph export derived from the publicly available **Traditional Chinese Medicine Multidimensional Knowledge Graph (TCM-MKG V1.0)**.

JX-Lab performed format conversion and schema normalization to make the resource easier to load for knowledge graph and machine learning workflows. The repository retains only the reorganized `nodes.tsv` and `edges.tsv` outputs. Copies of the original Zenodo tables and documentation are not distributed in this public repository.

The legacy directory name `original_kg/` is retained for API and link compatibility; its files are reorganized exports generated by JX-Lab, not the untouched original source tables.

## Files

- `original_kg/nodes.tsv`: 369,912 normalized node records
- `original_kg/edges.tsv`: 48,849,793 normalized relationship records

The exported schema preserves provenance fields such as `source_table`, `evidence`, and `attributes_json` so records can be traced back to source-table identifiers.

## Original Source And Attribution

The underlying knowledge content comes from:

**Traditional Chinese Medicine Multidimensional Knowledge Graph (TCM-MKG V1.0)**

- Original authors: Zeng, Jingqi; Jia, Xiaobin
- Publisher: China Pharmaceutical University
- Original source: https://doi.org/10.5281/zenodo.13763953
- Original release year: 2024

TCM-MKG integrates information from multiple biomedical, terminology, pharmacopoeia, and traditional Chinese medicine databases. Rights in that source content remain with the original authors and the respective upstream rights holders.

## What JX-Lab Changed

JX-Lab's contribution is limited to technical organization and format conversion, including:

- transforming source-specific tables into unified node and edge tables
- normalizing entity identifiers and relationship fields
- retaining source-table provenance and structured attributes
- preparing Hugging Face dataset configurations for streaming and loading

No claim is made that JX-Lab collected the original biomedical evidence or created the original TCM-MKG knowledge resource.

## License And Third-Party Rights

This repository is marked `license: other` because the original Zenodo record does not specify a formal license in its Rights/License field. JX-Lab does not apply a new blanket CC BY, MIT, or other license to the underlying source data.

Use of this reorganized export remains subject to:

1. the terms stated by the original TCM-MKG authors;
2. the licenses and terms of each incorporated upstream database or terminology;
3. applicable copyright, database-right, contract, attribution, and research-use requirements.

Public availability does not by itself remove those obligations. Users must verify that their intended use, especially redistribution or commercial use, is permitted.

## Usage

```python
from datasets import load_dataset

nodes = load_dataset("JX-Lab/TCM-MKG", "nodes", split="train")
edges = load_dataset("JX-Lab/TCM-MKG", "edges", split="train", streaming=True)
```

Streaming is recommended for the edge table.

## Citation

Please cite the original dataset:

```bibtex

When describing this repository, please identify it as a reorganized Hugging Face export and indicate that JX-Lab performed the format conversion.
