Dataset Creation

Curation Rationale

PolyFiQA-Easy was curated to provide a lightweight yet robust benchmark for financial question answering with minimal retrieval burden. It aims to evaluate models’ reasoning on self-contained or short-context questions in finance.

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 authored and verified through a multi-step validation pipeline involving domain experts.

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-Easy contributes to research in financial NLP by enabling multilingual evaluation under constrained settings.

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 easy questions; may not generalize to complex reasoning tasks.
