This dataset was created by filtering and adding columns needed to evaluate retrievers to "v1.1" version of [MSMARCO dataset] (https://github.com/microsoft/MSMARCO-Question-Answering). I am additionally providing the code used to filter the dataset in order to make everything clear.
msmarco = load_dataset("ms_marco", "v1.1", split="train").to_pandas()
msmarco["golden_passages"] = [row["passages"]["passage_text"][row["passages"]["is_selected"]==1] for _, row in msmarco.iterrows()]
msmarco_correct_answers = msmarco[msmarco["answers"].apply(lambda x: len(x) == 1)]
msmarco_correct_answers = msmarco_correct_answers[msmarco_correct_answers["wellFormedAnswers"].apply(lambda x: len(x) == 0)]
msmarco_correct_answers.dropna(inplace=True)
msmarco_correct_answers["answer"] = msmarco_correct_answers["answers"].apply(lambda x: x[0])
msmarco_correct_answers.drop(["wellFormedAnswers", "answers"], axis=1, inplace=True)
msmarco_correct_answers.reset_index(inplace=True, drop=True)
