Unanswerable questions for LLM hallucations
Project description
NoMIRACL: A Multilingual Hallucination Evaluation Dataset for Robust RAGs
The image has been generated using miramuseai.net and Adobe Photoshop.
NoMIRACL is multilingual hallucination evaluation dataset across 18 diverse languages. It includes both a non-relevant and a relevant subset. The non-relevant subset contains queries with passages manually judged as non-relevant, while the relevant subset includes queries with at least one judged relevant passage. LLM robustness is measured using two key metrics: hallucination rate
and error rate
.
This repository provides easy code to implement and evaluate diverse LLM baselines using our prompt template on NoMIRACL.

:star: Getting Started
1. Load NoMIRACL Dataset
- 50% of relevant examples, 50% of non-relevant, both maximum capped at 250.
- Full example available in sample_load_no_miracl.py.
from nomiracl.dataset import NoMIRACLDataLoader
data_loader = NoMIRACLDataLoader(language = "english,
split = "test", # or 'dev'
hf_dataset_name="miracl/nomiracl",
load_from_huggingface=True)
corpus, queries, qrels = data_loader.load_data_sample(
relevant_ratio = 0.5, non_relevant_ratio = 0.5, max_sample_pool = 250)
2. LLM prompt generation
- Full example available in sample_model_generation.py.
from nomiracl.generation.utils import load_model
model_name = "zephyr-7b-beta"
weights_path = f"HuggingFaceH4/{model_name}"
model = load_model(model_name, weights_path=weights_path, cache_dir=None)
# Sample prompts
prompts = [
"What is the capital of France?",
"What is the capital of Germany?",
"What is the capital of Italy?",
]
model_results = model.batch_call(prompts, batch_size=1)
for prompt, result in zip(prompts, model_results):
print("Prompt: {}".format(prompt))
print("{} result: {}".format(model_name, result))
3. Loading Vanilla prompt template
- Full example available in sample_vanilla_prompt_exploration.py.
from nomiracl.prompts.utils import load_prompt_template
prompt_cls = load_prompt_template("vanilla", count = 10)
query = "Which is the best programming language?"
passages = [
"Python is the best programming language.",
"Javascript is the best programming language.",
"Go is the best programming language.",
"Java is the best programming language.",
"C# is the best programming language.",
"Ruby is the best programming language.",
"R is the best programming language.",
"C++ is the best programming language.",
"C is the best programming language.",
"Rust is the best programming language.",
]
prompt = prompt_cls(query=query, passages=passages)
print(prompt)

NoMIRACL Dataset Construction
Retrieval Augmented Generation (RAG) is a powerful approach to incorporate external knowledge into large language models (LLMs) to enhance the accuracy and faithfulness of generated responses. However, evaluating LLM robustness in RAG across different language families has been a challenge, leading to gaps in understanding the model's performance against errors in external retrieved knowledge. To address this, we present NoMIRACL, a human-annotated dataset designed for evaluating LLM robustness in RAG across 18 typologically diverse languages.
NoMIRACL is a multilingual dataset designed to evaluate LLM robustness against errors in first-stage retrieval. The dataset covers 18 typologically diverse languages and includes two subsets: non-relevant and relevant.
Non-Relevant Subset (F)
- Queries with no-known answers.
- All top-k passages manually judged as non-relevant (relevancy score = 0).
Relevant Subset (T)
- Queries with known answers.
- At least one of the top-k passages manually judged as relevant (relevancy score = 1).
Evaluation Metrics
We conduct a robustness evaluation using a binary classification task, comparing LLM predictions against the ground truth provided in NoMIRACL. The metrics used are hallucination rate and error rate.
-
Hallucination Rate:
FP/(FP + TN)
Measures the model's tendency to hallucinate an answer when no answer is present in the non-relevant subset. -
Error Rate:
FN/(FN + TP)
Measures the model's inaccuracy in recognizing relevant passages in the relevant subset.
