🔗 Chain-of-Thought Structure

Each question contains annotated reasoning steps:

{
  "reasoning_steps": [
    {
      "step": 1,
      "description": "Extract values from the financial report",
      "intermediate_result": "bal_1600 = 633.696, inc_2400 = 44.691",
      "is_critical": true
    },
    {
      "step": 2,
      "description": "Apply the ROA formula",
      "intermediate_result": "ROA = 44.691 / 633.696",
      "is_critical": true
    },
    {
      "step": 3,
      "description": "Compute the result",
      "intermediate_result": "ROA = 0.0705 (7.05%)",
      "is_critical": true
    }
  ],
  "cot_text": "Step 1: ... → ...\nStep 2: ... → ...\n\nAnswer: ...",
  "final_answer": "ROA = 44.691 / 633.696 = 0.0705 (7.05%)"
}

🚀 Usage

Loading the Benchmark

from datasets import load_dataset

dataset = load_dataset("arabovs-ai-lab/RuFinQA-CoT", split="train")
print(f"Total questions: {len(dataset)}")
print(dataset[0])

Example Usage for LLM Evaluation

import json
from datasets import load_dataset

dataset = load_dataset("arabovs-ai-lab/RuFinQA-CoT", split="train")

# Filter by task type
arithmetic_tasks = [d for d in dataset if d['type'] == 'arithmetic']
print(f"Arithmetic tasks: {len(arithmetic_tasks)}")

# Sample question
sample = arithmetic_tasks[0]
print(f"Question: {sample['question']}")
print(f"Expected answer: {sample['final_answer']}")
print(f"CoT:\n{sample['cot_text']}")

Model Evaluation

# Simple evaluation example
def evaluate_numeric(prediction: str, ground_truth: float, tolerance: float) -> bool:
    import re
    numbers = [float(x) for x in re.findall(r'-?\d+\.?\d*', prediction)]
    return any(abs(n - ground_truth) <= tolerance for n in numbers)

# Check model output
model_output = "ROA = 0.0705 (7.05%)"
is_correct = evaluate_numeric(model_output, 0.0705, 0.001)
print(f"Answer is correct: {is_correct}")

🤖 Evaluated Models

Model evaluations will be added in future releases.

🔬 Benchmark Features
