+VIMQA, a new Vietnamese dataset with over 10,000 Wikipedia-based multi-hop question-answer pairs. The dataset is human-generated and has four main features:
+The questions require advanced reasoning over multiple paragraphs.
+Sentence-level supporting facts are provided, enabling the QA model to reason and explain the answer.
+The dataset offers various types of reasoning to test the model's ability to reason and extract relevant proof.
+The dataset is in Vietnamese, a low-resource language
