Dataset Card for Narrative QA

Dataset Summary

NarrativeQA is an English-lanaguage dataset of stories and corresponding questions designed to test reading comprehension, especially on long documents.

Supported Tasks and Leaderboards

The dataset is used to test reading comprehension. There are 2 tasks proposed in the paper: "summaries only" and "stories only", depending on whether the human-generated summary or the full story text is used to answer the question.

Dataset Structure

Data Instances

A typical data point consists of a question and answer pair along with a summary/story which can be used to answer the question. Additional information such as the url, word count, wikipedia page, are also provided.

A typical example looks like this:

{
    "document": {
        "id": "23jncj2n3534563110",
        "kind": "movie",
        "url": "https://www.imsdb.com/Movie%20Scripts/Name%20of%20Movie.html",
        "file_size": 80473,
        "word_count": 41000,
        "start": "MOVIE screenplay by",
        "end": ". THE END",
        "summary": {
            "text": "Joe Bloggs begins his journey exploring...",
            "tokens": ["Joe", "Bloggs", "begins", "his", "journey", "exploring",...],
            "url": "http://en.wikipedia.org/wiki/Name_of_Movie",
            "title": "Name of Movie (film)"
        },
        "text": "MOVIE screenplay by John Doe\nSCENE 1..."
    },
    "question": {
        "text": "Where does Joe Bloggs live?",
        "tokens": ["Where", "does", "Joe", "Bloggs", "live", "?"],
    },
    "answers": [
        {"text": "At home", "tokens": ["At", "home"]},
        {"text": "His house", "tokens": ["His", "house"]}
    ]
}

Data Fields

• document.id - Unique ID for the story.
• document.kind - "movie" or "gutenberg" depending on the source of the story.
• document.url - The URL where the story was downloaded from.
• document.file_size - File size (in bytes) of the story.
• document.word_count - Number of tokens in the story.
• document.start - First 3 tokens of the story. Used for verifying the story hasn't been modified.
• document.end - Last 3 tokens of the story. Used for verifying the story hasn't been modified.
• document.summary.text - Text of the wikipedia summary of the story.
• document.summary.tokens - Tokenized version of document.summary.text.
• document.summary.url - Wikipedia URL of the summary.
• document.summary.title - Wikipedia Title of the summary.
• question - {"text":"...", "tokens":[...]} for the question about the story.
• answers - List of {"text":"...", "tokens":[...]} for valid answers for the question.

Data Splits

The data is split into training, valiudation, and test sets based on story (i.e. the same story cannot appear in more than one split):

Curation Rationale

Source Data

Initial Data Collection and Normalization

Stories and movies scripts were downloaded from Project Gutenburg and a range of movie script repositories (mainly imsdb).

Who are the source language producers?

The language producers are authors of the stories and scripts as well as Amazon Turk workers for the questions.

Annotations

Annotation process

Amazon Turk Workers were provided with human written summaries of the stories (To make the annotation tractable and to lead annotators towards asking non-localized questions). Stories were matched with plot summaries from Wikipedia using titles and verified the matching with help from human annotators. The annotators were asked to determine if both the story and the summary refer to a movie or a book (as some books are made into movies), or if they are the same part in a series produced in the same year. Annotators on Amazon Mechanical Turk were instructed to write 10 question–answer pairs each based solely on a given summary. Annotators were instructed to imagine that they are writing questions to test students who have read the full stories but not the summaries. We required questions that are specific enough, given the length and complexity of the narratives, and to provide adiverse set of questions about characters, events, why this happened, and so on. Annotators were encouraged to use their own words and we prevented them from copying. We asked for answers that are grammatical, complete sentences, and explicitly allowed short answers (one word, or a few-word phrase, or ashort sentence) as we think that answering with a full sentence is frequently perceived as artificial when asking about factual information. Annotators were asked to avoid extra, unnecessary information in the question or the answer, and to avoid yes/no questions or questions about the author or the actors.

Who are the annotators?

Amazon Mechanical Turk workers.
