### Dataset Summary

**PolyFiQA-Expert** is a multilingual financial question-answering dataset designed to evaluate expert-level financial reasoning in low-resource and multilingual settings. Each instance consists of a task identifier, a query prompt, an associated financial question, and the correct answer.The Expert split emphasizes complex, high-level financial understanding, requiring deeper domain knowledge and nuanced reasoning.

### Supported Tasks and Leaderboards

- **Tasks:**
  - question-answering
- **Evaluation Metrics:**
  - ROUGE-1

### Languages

- English (en)
- Chinese (zh)
- Japanese (jp)
- Spanish (es)
- Greek (el)

## Dataset Structure

### Data Instances

Each instance in the dataset contains:

- `task_id`: A unique identifier for the query-task pair.
- `query`: A brief query statement from the financial domain.
- `question`: The full question posed based on the query context.
- `answer`: The correct answer string.

## Dataset Creation

### Curation Rationale

PolyFiQA-Expert was curated to probe the financial reasoning capabilities of large language models under expert-level scenarios

### Source Data

#### Initial Data Collection

The source data was derived from a diverse collection of English financial reports. Questions were derived from real-world financial scenarios and manually adapted to fit a concise QA format.

#### Source Producers

Data was created by researchers and annotators with backgrounds in finance, NLP, and data curation.

### Annotations

#### Annotation Process

Questions and answers were carefully authored and validated through a multi-round expert annotation process to ensure fidelity and depth.

#### Annotators

A team of finance researchers and data scientists.

### Personal and Sensitive Information

The dataset contains no personal or sensitive information. All content is synthetic or anonymized for safe usage.

## Considerations for Using the Data

### Social Impact of Dataset

PolyFiQA-Expert contributes to research in financial NLP supports research in multilingual financial QA, with applications in risk analysis, regulatory auditing, and financial advising tools.

### Discussion of Biases

- May over-represent English financial contexts.
- Questions emphasize clarity and answerability over real-world ambiguity.

### Other Known Limitations

- Limited size (76 examples).
- Focused on expert questions; may not generalize to complex reasoning tasks.
