# FinLFQA

[**📖 Paper**](https://aclanthology.org/anthology-files/anthology-files/pdf/findings/2025.findings-emnlp.908.pdf) | [**💻 GitHub**](https://github.com/yitaoLong/FinLFQA)

The dataset for the paper [FinLFQA: Evaluating Attributed Text Generation of LLMs in Financial Long-Form Question Answering](https://aclanthology.org/anthology-files/anthology-files/pdf/findings/2025.findings-emnlp.908.pdf).

**FinLFQA** is a benchmark for evaluating the ability of large language models (LLMs) to generate long-form answers with fine-grained attributions in the financial domain. Unlike existing benchmarks that focus on short-form or extractive QA, FinLFQA requires models to synthesize information from multiple financial documents, apply professional financial knowledge, perform numerical reasoning, and provide clause-level attribution for every claim in their response.

## Dataset Overview

FinLFQA contains **1,008** expert-annotated examples spanning diverse financial analysis topics. Each example requires the model to reason over financial filings from **two companies**, apply domain-specific knowledge (e.g., profitability ratios, DCF valuation, capital structure optimization), and produce a structured, multi-clause answer with fine-grained attribution.

| Split | # Samples |
|-------|-----------|
| Development | 302 |
| Test | 706 |

### Key Features

- **Cross-document reasoning**: Each question requires synthesizing information from two companies' financial filings.
- **Fine-grained attribution**: Answers are decomposed into clauses, each attributed to specific evidence paragraphs, professional knowledge, and/or computational code.
- **Numerical reasoning**: Answers involve quantitative calculations grounded in financial formulas and verifiable through executable Python code.
- **Professional knowledge grounding**: Each example includes a list of relevant financial formulas and domain knowledge used in reasoning.

## Loading the Dataset

```python
from datasets import load_dataset
import json

dataset = load_dataset("Dragongon/FinLFQA")

# Access the development set
dev_set = dataset["validation"]
print(f"Development set size: {len(dev_set)}")

# Access the test set
test_set = dataset["test"]
print(f"Test set size: {len(test_set)}")

# Print the first example
example = dev_set[0]
# The `context` and `clauses` fields are JSON-encoded strings; parse them as needed:
context = json.loads(example["context"])
clauses = json.loads(example["clauses"])
print(example["question"])
print("Companies:", list(context.keys()))
print("Number of clauses:", len(clauses))
```

## Data Format

Each example in the dataset contains the following fields:

```json

Each clause in the `clauses` field contains:

```json
{
    "cid": "[int] Clause ID",
    "clause": "[string] The claim text",
    "inference": "[list] Indices of clauses this clause infers from",
    "evidence": "[dict] Mapping from company ticker to paragraph indices used as evidence",
    "professional knowledge": "[string] The financial formula or knowledge applied",
    "code": "[string] Executable Python code for numerical verification",
    "code_execution_result": "[string] Result of executing the code"
}
```

### Example

```json
{
    "id": 0,
    "question": "How does EBC's net interest income sensitivity compare between March 31, 2024, and December 31, 2023, when the interest rate change is +200 basis points?",
    "answer": "EBC's net interest income sensitivity decreased by 0.2% {code: [0]} (2.9% - 3.1%) from December 31, 2023, to March 31, 2024. {evidence: EBC: [4], W: [], professional knowledge: [0]} ...",
    "topic": "Cost of Capital Optimization Using Real Options Analysis",
    "clauses": [
        {
            "cid": 0,
            "clause": "EBC's net interest income sensitivity decreased by 0.2% (2.9% - 3.1%) from December 31, 2023, to March 31, 2024.",
            "inference": [],
            "evidence": {"EBC": [4], "W": []},

            "code": "def calculate_net_interest_income_sensitivity_change(): ...",
            "code_execution_result": "0.20000000000000018"
        }
    ],
    "context": {
        "EBC": ["paragraph 1", "paragraph 2", "..."],
        "W": ["paragraph 1", "paragraph 2", "..."]
    },

    abstract = "Large Language Models (LLMs) frequently hallucinate to long-form questions, producing plausible yet factually incorrect answers. A common mitigation strategy is to provide attribution to LLM outputs. However, existing benchmarks primarily focus on simple attribution that retrieves supporting textual evidence as references. We argue that in real-world scenarios such as financial applications, attribution goes beyond reference retrieval.We introduce FinLFQA, a benchmark designed to evaluate the ability of LLMs to generate long-form answers to complex financial questions with reliable and nuanced attributions. FinLFQA evaluates three critical aspects of attribution through human annotations: (1) supporting evidence extracted from financial reports, (2) intermediate numerical reasoning steps, and (3) domain-specific financial knowledge that informs the reasoning process.We further provide an automatic evaluation framework covering both answer quality and attribution quality. Through extensive experiments on eight LLMs across multiple attribution-generation paradigms, we find that fine-grained metrics are important to distinguish model capabilities, that end-to-end generation achieves comparable performance to post-hoc approaches, and that iterative refinement only helps when guided by external feedback."
