# MoreHopQA: More Than Multi-hop Reasoning

<!-- Provide a quick summary of the dataset. -->

We propose a new multi-hop dataset, MoreHopQA, which shifts from extractive to generative answers. Our dataset is created by utilizing three existing multi-hop datasets: [HotpotQA](https://github.com/hotpotqa/hotpot), [2Wiki-MultihopQA](https://github.com/Alab-NII/2wikimultihop), and [MuSiQue](https://github.com/StonyBrookNLP/musique). Instead of relying solely on factual reasoning, we enhance the existing multi-hop questions by adding another layer of questioning.

## Dataset Details

### Dataset Description

<!-- Provide a longer summary of what this dataset is. -->

Our dataset is created through a semi-automated process, resulting in a dataset with 1118 samples that have undergone human verification.  
For each sample, we share our 6 evaluation cases, including the new question, the original question, all the necessary subquestions, and a composite question from the second entity to the final answer (case 3 above).
We share both a version where each question was verified by a human, and a larger, solely automatically generated version ("unverified"). We recommend to primarily use the human-verified version.

## Uses

<!-- Address questions around how the dataset is intended to be used. -->
We provide our dataset to the community and hope that other researchers find it a useful tool to analyze and improve the multi-hop reasoning capabilities of their models. MoreHopQA is designed to challenge systems with complex queries requiring synthesis from multiple sources, thereby advancing the field in understanding and generating nuanced, context-rich responses. Additionally, we aim for this dataset to spur further innovation in reasoning models, helping to bridge the gap between human-like understanding and AI capabilities.

## Dataset Structure

<!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->

We share both a version where each question was verified by a human, and a larger, solely automatically generated version ("unverified"). We recommend to primarily use the human-verified version, which is also the default option when loading the dataset.
