Introduction

The PersianMHQA Dataset is the first open-domain, multi-hop question answering dataset, containing 7,000 questions generated using Persian Wikipedia texts. It was developed with the assistance of linguists in the Web Mining and Search Engines Lab at Iran University of Science and Technology. We have currently made available 500 samples from the dataset records to introduce this dataset. Soon, after the publication of the paper, the entire dataset will be accessible.
