VMHQA is a pioneering Vietnamese Multiple-Choice Question Answering (MCQA) dataset designed specifically for the mental health domain. Comprising 10,000 high-quality question-answer pairs across 1,166 subjects, this dataset addresses critical gaps in mental health resources for Vietnamese-speaking communities.

Dataset Details

Domain-Specific Design
Questions are crafted based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), ensuring relevance to mental health diagnoses.
High-Quality Annotations
Each question includes multiple-choice options, the correct answer, and supporting paragraphs derived from trusted academic and medical sources, verified by mental health professionals.
Alignment with Medical Standards
Adhering to the United States Medical Licensing Examination (USMLE) format, VMHQA ensures quality meets global medical standards.
Advanced Question Types
Features diverse and complex question types, challenging AI models to reason, comprehend, and apply knowledge effectively.
Advancing Vietnamese NLP
As the largest Vietnamese QA dataset in the mental health domain, VMHQA significantly contributes to the development of natural language processing (NLP) resources for a low-resource language.

Dataset Overview

Collected manually by human: 10,066
Generated by GPT-4o: 2,200 records
Generated by GPT-4o-mini: 5,000 records

Dataset Structure

The dataset is provided in CSV format. Each row represents a single question-answer data point with the following columns:

Topic: Main topic or category of the question.
Question: The question text describing the scenario or problem.
Answer: The correct answer option (1-based index corresponding to A, B, C, or D).
A, B, C, D: The multiple-choice options for the question.
Paragraph 1, Paragraph 2, Paragraph 3: Contextual paragraphs supporting the question and answers.
Fact 1, Fact 2, Fact 3: Key supporting facts extracted from the paragraphs to justify the correct answer.
Question_Type: The type of question (e.g., "Complex").
Reference: Source link or reference for the information provided.
ID: A unique identifier for each question-answer data point.
Sub_topic: Specific subcategory of the topic.
Subject: Broader subject area related to the topic.

This structured format ensures clarity and supports effective training and evaluation of AI models in the Vietnamese mental health domain.

Dataset Creation

The VMHQA dataset was developed following these steps:
