MuSR

Reasoning

MuSR poses multistep soft reasoning problems over algorithmically generated narratives. It has three domains — murder mysteries, object placements and team allocation — and this catalogue imports the murder-mystery set.

Metric: accuracy over the 250 problems in each domain
Size: 200 problems imported from the murder-mystery selection of 250, with a source-row limit of 200.
License: cc-by-4.0 (declared on the Hugging Face dataset card)
Released: Dataset published on Hugging Face 2024-05
Maintainer: TAUR-Lab (source organisation)
Answer access: Columns outside the prompt allowlist, including any answer or reference solution, are separated into restricted storage and never rendered.

What a problem looks like

A narrative of several hundred words, a question about it, and the candidate answers as a list. The correct index is not part of the prompt.

How it is scored

The source ships the answer index and the chosen option; this catalogue keeps both in restricted storage and never renders them.

Metric: accuracy over the 250 problems in each domain

Why it is hard

The clues are spread through a long narrative and none of them decides the answer alone. The chain has to be assembled from commonsense inferences that the text never states.
