🍄 UHGEval: Benchmarking the Hallucination of Chinese Large Language Models via Unconstrained Generation

What does this repository include?
UHGEval: An unconstrained hallucination evaluation benchmark.
Eval Suite: A user-friendly evaluation framework for hallucination tasks.
Eval Suite supports other benchmarks, such as HalluQA and HaluEval.

Quick Start

# Install Eval Suite
conda create -n uhg python=3.10
conda activate uhg
pip install eval-suite

# Run evaluations with OpenAI Compatible API
eval_suite eval openai \
    --model_name gpt-4o \
    --api_key your_api_key \
    --base_url https://api.openai.com/v1 \
    --evaluators ExampleQAEvaluator UHGSelectiveEvaluator

# Or run evaluations with Hugging Face Transformers
eval_suite eval huggingface \
    --model_name_or_path Qwen/Qwen2-0.5B-Instruct \
    --apply_chat_template \
    --evaluators ExampleQAEvaluator UHGSelectiveEvaluator

# After evaluation, you can gather statistics of the evaluation results

Tip

• Refer to demo.ipynb for more detailed examples.
• Run export HF_ENDPOINT=https://hf-mirror.com to use the Chinese mirror if you cannot connect to Hugging Face.
• SilliconFlow provides free API keys for many models, and you can apply for one at https://siliconflow.cn/pricing.

UHGEval

UHGEval is a large-scale benchmark designed for evaluating hallucination in professional Chinese content generation. It builds on unconstrained text generation and hallucination collection, incorporating both automatic annotation and manual review.

UHGEvalDataset. UHGEval contains two dataset versions. The full version includes 5,141 data items, while a concise version with 1,000 items has been created for more efficient evaluation. Below is an example in UHGEvalDataset.

Evaluation Methods. UHGEval offers a variety of evaluation methods, including discriminative evaluation, generative evaluation, and selective evaluation.

Evaluator	Metric	Description
UHGDiscKeywordEvaluator	Average Accuracy	Given a keyword, the LLM determines whether it contains hallucination.
UHGDiscSentenceEvaluator	Average Accuracy	Given a sentence, the LLM determines whether it contains hallucination.
UHGGenerativeEvaluator	BLEU-4, ROUGE-L, kwPrec, BertScore	Given a continuation prompt, the LLM generates a continuation.
UHGSelectiveEvaluator	Accuracy	Given hallucinated text and unhallucinated text, the LLM selects the realistic text.

Eval Suite

To facilitate evaluation, we have developed a user-friendly evaluation framework called Eval Suite. Currently, Eval Suite supports common hallucination evaluation benchmarks, allowing for comprehensive evaluation of the same LLM with just one command as shown in the Quick Start section.
