EvasionBench is a benchmark dataset for detecting **evasive answers** in earnings call Q&A sessions. The task is to classify how directly corporate management addresses questions from financial analysts.

## Dataset Description

- **Repository:** [https://github.com/IIIIQIIII/EvasionBench](https://github.com/IIIIQIIII/EvasionBench)
- **Paper:** [https://arxiv.org/abs/2601.09142](https://arxiv.org/abs/2601.09142)
- **Point of Contact:** [GitHub Issues](https://github.com/IIIIQIIII/EvasionBench/issues)

### Dataset Summary

This dataset contains 16,726 question-answer pairs from earnings call transcripts, each labeled with one of three evasion levels. The labels were generated using the Eva-4B-V2 model, a fine-tuned classifier specifically trained for financial discourse evasion detection.

### Supported Tasks

- **Text Classification**: Classify the directness of management responses to analyst questions.

### Languages

English

## Dataset Structure

### Data Fields

| Field | Type | Description |
|-------|------|-------------|
| `uid` | string | Unique identifier for each sample |
| `question` | string | Analyst's question during the earnings call |
| `answer` | string | Management's response to the question |
| `eva4b_label` | string | Evasion label: `direct`, `intermediate`, or `fully_evasive` |

### Label Definitions

| Label | Definition | Description |
|-------|------------|-------------|
| `direct` | The core question is directly and explicitly answered | Clear figures, "Yes/No" stance, or direct explanations |
| `intermediate` | The response provides related context but sidesteps the specific core | Hedging, providing a range instead of a point, or answering adjacent topics |
| `fully_evasive` | The question is ignored, explicitly refused, or the response is entirely off-topic | Explicit refusal, total redirection, or irrelevant responses |

### Data Statistics

| Metric | Value |
|--------|-------|
| Total Samples | 16,726 |
| Direct | 8,749 (52.3%) |
| Intermediate | 7,359 (44.0%) |
| Fully Evasive | 618 (3.7%) |

### Example

```python
{
    "uid": "4addbff893b81f64131fdc712d7a6d9a",
    "question": "What is the expected margin for Q4?",
    "answer": "We expect it to be 32%.",
    "eva4b_label": "direct"
}
```

## Usage

### Loading the Dataset

```python
from datasets import load_dataset

dataset = load_dataset("FutureMa/EvasionBench")
```

### Loading from Parquet

```python
import pandas as pd

df = pd.read_parquet("evasionbench_17k_eva4b_labels_dedup.parquet")
```

### Quick Start: Inference with Eva-4B-V2

````python
from datasets import load_dataset
from transformers import pipeline

# Load dataset
dataset = load_dataset("FutureMa/EvasionBench")

# Load model using text-generation pipeline
pipe = pipeline("text-generation", model="FutureMa/Eva-4B-V2", device_map="auto")

# Get a sample
sample = dataset["train"][0]
question = sample["question"]
answer = sample["answer"]

# Prepare prompt
prompt = f"""You are a financial analyst. Your task is to Detect Evasive Answers in Financial Q&A

Question: {question}
Answer: {answer}

Response format:
```json
{{"label": "direct|intermediate|fully_evasive"}}
```

Answer in ```json content, no other text"""

# Run inference
result = pipe(prompt, max_new_tokens=64, do_sample=False)
print(result[0]["generated_text"])
````

For a complete inference example with batch processing and evaluation, see our [Colab notebook](https://colab.research.google.com/github/IIIIQIIII/EvasionBench/blob/main/scripts/eva4b_inference.ipynb).

## Dataset Creation

### Source Data

The question-answer pairs are derived from publicly available earnings call transcripts.

### Annotation Process

Labels were generated using **Eva-4B-V2**, a 4B parameter model fine-tuned specifically for evasion detection in financial discourse. Eva-4B-V2 achieves 84.9% Macro-F1 on the EvasionBench evaluation set, outperforming frontier LLMs including Claude Opus 4.5 and Gemini 3 Flash.

## Considerations for Using the Data

### Social Impact

This dataset can be used to:
- Improve transparency in corporate communications
- Assist financial analysts in identifying evasive responses
- Support research in financial NLP and discourse analysis

### Limitations

- Labels are model-generated (Eva-4B-V2) rather than human-annotated
- The dataset reflects the distribution of evasion patterns in the source data
- Performance may vary across different industries or time periods
