Dataset Description

The dataset contains simple, long-form answers to questions and corresponding contexts. Similar to ELI5 but with context.

This dataset is a filtered version of LLukas22/lfqa_preprocessed, which in turn is a processed and simplified version of of vblagoje's lfqa_support_docs and lfqa datasets.

I have filtered out overly long answers, based on the number of tokens in the answer using the LED tokenizer. It can be reproduced with the notebook process-lfqa-dataset.ipynb.

LLukas22/lfqa_preprocessed	stefanbschneider/lfqa-max-answer-length-1024

Max answer length: 5964 tokens	Max answer length: 1024 tokens (~6x shorter)
Num answers (train): 226147	Num answers (train): 218894 (~3% less)

Dataset Structure

Data Instances

An example of 'train' looks as follows.

{
    "question": "what's the difference between a forest and a wood?",
    "answer": "They're used interchangeably a lot. You'll get different answers from different resources, but the ...",
    "context": [
        "Wood is divided, according to its botanical origin, into two kinds: softwoods, ...",
        "Processing and products differs especially with regard to the distinction between softwood and hardwood ..."
    ]
}

Data Fields

The data fields are the same among all splits.

question: a string feature.
answer: a string feature.
context: a list feature containing string features.
