Dataset Card for AmbigQA: Answering Ambiguous Open-domain Questions

Table of Contents

Dataset Description

Dataset Summary

AmbigNQ, a dataset covering 14,042 questions from NQ-open, an existing open-domain QA benchmark. We find that over half of the questions in NQ-open are ambiguous. The types of ambiguity are diverse and sometimes subtle, many of which are only apparent after examining evidence provided by a very large text corpus. AMBIGNQ, a dataset with 14,042 annotations on NQ-OPEN questions containing diverse types of ambiguity. We provide two distributions of our new dataset AmbigNQ: a full version with all annotation metadata and a light version with only inputs and outputs.

In the original data format annotations have different keys depending on the type field = singleAnswer or multipleQAs. But this implementation uses an empty list [] for the unavailable keys

please refer to Dataset Contents(https://github.com/shmsw25/AmbigQA#dataset-contents) for more details.

for example in train_light_dataset:
    for i,t in enumerate(example['annotations']['type']):
        if t =='singleAnswer':
            # use the example['annotations']['answer'][i]
            # example['annotations']['qaPairs'][i] - > is []
            print(example['annotations']['answer'][i])
        else:
