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.

⭐ 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.
