ChineseHarm-bench

A Chinese Harmful Content Detection Benchmark

⚠️ WARNING: This project and associated data contain content that may be toxic, offensive, or disturbing. Use responsibly and with discretion.

🌟Overview

We introduce ChineseHarm-Bench, a professionally annotated benchmark for Chinese harmful content detection, covering six key categories. It includes a knowledge rule base to enhance detection and a knowledge-augmented baseline that enables smaller LLMs to match state-of-the-art performance.

The benchmark construction process is illustrated in the figure above and for more detailed procedures, please refer to our paper.

🌟Benchmark

This folder contains the ChineseHarm-Bench.

bench.json is the full benchmark combining all categories.
The other files (e.g., 低俗色情.json, 欺诈.json) are category-specific subsets.

Each file is a list of examples with:

"文本": the input Chinese text
"标签": the ground-truth label

Sample Usage (Inference)

Our inference scripts support both Huawei Ascend NPUs and NVIDIA GPUs, enabling flexible deployment across different hardware platforms. For the full scripts and details, please refer to the GitHub repository.

We release the following variants of our harmful content detection model:

🔹 Single Inference (Example)

Run single-input inference using the ChineseGuard-1.5B model:

SCRIPT_PATH="../infer/single_infer.py"
model_name="zjunlp/ChineseHarm-1.5B"
text="代发短信，有想做的联系我，无押金"

python $SCRIPT_PATH \
    --model_name $model_name \
    --text $text

🔸 Batch Inference (Multi-NPU or Multi-GPU)

To run inference on the entire ChineseHarm-Bench using ChineseGuard-1.5B and 8 NPUs:

SCRIPT_PATH="../infer/batch_infer.py"
model_name="zjunlp/ChineseHarm-1.5B"
file_name="../benchmark/bench.json"
output_file="../benchmark/bench_ChineseHarm-1.5B.json"

python $SCRIPT_PATH \
    --model_name $model_name \
    --file_name $file_name \
    --output_file $output_file \
    --num_npus 8

For more configuration options (e.g., batch size, device selection, custom prompt templates), please refer to single_infer.py and batch_infer.py in the code repository.

Note: The inference scripts support both NPU and GPU devices.

Evaluation: Calculating F1 Score

After inference, evaluate the predictions by computing the F1 score with the following command:

python ../calculate_metrics.py \
    --file_path "../benchmark/bench_ChineseHarm-1.5B.json" \
    --true_label_field "标签" \
    --predicted_label_field "predict_label"
