Japanese Question Answering Dataset (JaQuAD), released in 2022, is a human-annotated dataset created for Japanese Machine Reading Comprehension. JaQuAD is developed to provide a SQuAD-like QA dataset in Japanese. JaQuAD contains 39,696 question-answer pairs. Questions and answers are manually curated by human annotators. Contexts are collected from Japanese Wikipedia articles.

For more information on how the dataset was created, refer to our paper, JaQuAD: Japanese Question Answering Dataset for Machine Reading Comprehension.

JaQuAD consists of three sets: train, validation, and test. They were created from disjoint sets of Wikipedia articles. The following table shows statistics for each set:

You can also download our dataset here. (The test set is not publicly released yet.)

from datasets import load_dataset
jaquad_data = load_dataset('SkelterLabsInc/JaQuAD')

We also provide a baseline model for JaQuAD for comparison. We created this model by fine-tuning a publicly available Japanese BERT model on JaQuAD. You can see the performance of the baseline model in the table below.

For more information on the model's creation, refer to JaQuAD.ipynb.

You can download the baseline model here.

from transformers import AutoModelForQuestionAnswering, AutoTokenizer

question = 'アレクサンダー・グラハム・ベルは、どこで生まれたの?'
context = 'アレクサンダー・グラハム・ベルは、スコットランド生まれの科学者、発明家、工学者である。世界初の>実用的電話の発明で知られている。'

model = AutoModelForQuestionAnswering.from_pretrained(
    'SkelterLabsInc/bert-base-japanese-jaquad')
tokenizer = AutoTokenizer.from_pretrained(
    'SkelterLabsInc/bert-base-japanese-jaquad')

inputs = tokenizer(
    question, context, add_special_tokens=True, return_tensors="pt")
input_ids = inputs["input_ids"].tolist()[0]
outputs = model(**inputs)
answer_start_scores = outputs.start_logits
answer_end_scores = outputs.end_logits

# Get the most likely start of the answer with the argmax of the score.
answer_start = torch.argmax(answer_start_scores)
# Get the most likely end of the answer with the argmax of the score.
# 1 is added to `answer_end` because the index of the score is inclusive.
answer_end = torch.argmax(answer_end_scores) + 1

answer = tokenizer.convert_tokens_to_string(
    tokenizer.convert_ids_to_tokens(input_ids[answer_start:answer_end]))
# answer = 'スコットランド'
