Dataset Card for "ai2_arc"

Dataset Summary

A new dataset of 7,787 genuine grade-school level, multiple-choice science questions, assembled to encourage research in advanced question-answering. The dataset is partitioned into a Challenge Set and an Easy Set, where the former contains only questions answered incorrectly by both a retrieval-based algorithm and a word co-occurrence algorithm. We are also including a corpus of over 14 million science sentences relevant to the task, and an implementation of three neural baseline models for this dataset. We pose ARC as a challenge to the community.

ARC-Challenge

• Size of downloaded dataset files: 680.84 MB
• Size of the generated dataset: 0.83 MB
• Total amount of disk used: 681.67 MB

An example of 'train' looks as follows.

{
    "answerKey": "B",
    "choices": {
        "label": ["A", "B", "C", "D"],
        "text": ["Shady areas increased.", "Food sources increased.", "Oxygen levels increased.", "Available water increased."]
    },
    "id": "Mercury_SC_405487",
    "question": "One year, the oak trees in a park began producing more acorns than usual. The next year, the population of chipmunks in the park also increased. Which best explains why there were more chipmunks the next year?"
}
