What is KorNAT(Korean National Alignment Test)?

The concept of National Alignment in the provided paper “KorNAT: LLM Alignment Benchmark for Korean Social Values and Common Knowledge” is defined as a measure of the alignment between a Large Language Model (LLM) and a targeted country, considering two dimensions: social value alignment and common knowledge alignment.

Social Value Alignment: This aspect evaluates how well a model understands nation-specific social values. Social values refer to the collective viewpoints of a nation’s citizens on critical issues to their society. For example, in the context of South Korea, this might involve understanding prevailing social attitudes and opinions on a variety of societal issues.

Common Knowledge Alignment: This focuses on how well the model captures basic knowledge related to the nation. Common knowledge encompasses information broadly recognized and understood by the populace, often considered as foundational or general knowledge. This can range from historical facts to cultural norms specific to a country.

Our paper emphasizes that for LLMs to be effectively deployed in a specific country, they must possess an understanding of the nation’s culture and basic knowledge, encompassing both these aspects of national alignment. We constructed the KorNAT benchmark to measure national alignment with South Korea, with a dataset including multiple-choice questions derived from large-scale surveys and educational materials reflecting Korean social values and common knowledge.

  • Social Value Dataset Construction Process:
    1. Topic Selection: Identified keywords related to current social issues and conflicts in Korea from sources such as news articles and social conflict reports.
    2. Question Generation: Generated questions using GPT-3.5-Turbo based on selected topics and relevant news articles. These questions were then refined through human review for relevance and clarity.
    3. Survey: Conducted a large-scale survey with 6,174 Korean participants on various social issues, using multiple-choice questions. Participants could indicate their degree of agreement or disagreement with each question. The survey included engaging questions to capture attention and questions to check the consistency of each participant. To ensure the quality of responses, a filtering process was implemented to screen out potentially problematic respondents.
    4. Response Adjustment: Considering the online nature of the survey and potential demographic imbalances in respondents, response data was adjusted to better reflect the socio-demographic distribution of Korea’s population.
  • Common Knowledge Dataset Construction Process:
    1. Source Material: Based on Korean textbooks and General Educational Development (GED) reference materials, covering subjects like Korean history, science, and mathematics.
    2. Question Generation: Human workers, rather than AI, crafted questions and answer options from the educational materials. This process was to ensure accuracy and alignment with the Korean education curriculum. The dataset included a mix of simple and complex questions. Simple questions required straightforward factual answers, while complex questions demanded more in-depth understanding or multi-step reasoning.
    3. Revisions: The questions underwent multiple rounds of revisions by different individuals to ensure quality control and adherence to the educational curriculum.

Our dataset was meticulously constructed to reflect social values and common knowledge in Korea, with particular attention given to the comprehensive collection and reflection of the opinions of a diverse group of Koreans in the social value dataset through a carefully designed survey.

You can find detailed information about the construction process through the link to the paper above.

Social Value Dataset (4K Samples)

Social values refer to the collective viewpoints of a nation’s citizens on critical issues to their society.

We created questions based on trending topics in Korea and obtained the ground truth label distribution by surveying people, receiving an average of 219 responses per question from a total of 6,174 Korean citizens.

Common Knowledge Dataset (6K Samples)

Common knowledge refers to common knowledge broadly recognized and understood by the populace, often considered as basic knowledge.

The questions are based on the compulsory education curriculum in Korea.

Evaluation

Social Value Alignment Evaluation:

  • Social Value Alignment (SVA) measures the extent to which a model’s responses align with the majority opinion in a given society.
  • The evaluation uses a dataset constructed from surveys on a wide range of societal issues, with each survey question offering multiple response options.
  • The survey involved 6,174 unique Korean participants, ensuring a comprehensive representation of Korean social values.
  • The alignment score for a model is calculated based on how closely its responses match the survey-derived distribution of responses for each question.
  • Additionally, two modified metrics are introduced:
    • Aggregated Social Value Alignment (A-SVA): This simplifies the response options by aggregating ‘Strongly Agree’ and ‘Agree,’ and ‘Strongly Disagree’ and ‘Disagree,’ to account for a broader agreement or disagreement with a statement.
    • Neutral-processed Social Value Alignment (N-SVA): This is applied for questions where no significant majority opinion exists, transforming the options into a ‘Neutral’ one-hot distribution.

Common Knowledge Alignment Evaluation:

  • Common Knowledge Alignment focuses on a model’s understanding of factual, nation-specific knowledge.
  • The evaluation uses a dataset based on Korean educational materials, including textbooks and General Educational Development (GED) reference materials, covering a range of subjects like Korean history, science, and social studies.
  • Each question in this dataset has one correct answer, aligning with established facts or widely accepted knowledge within the Korean educational curriculum.
  • The model’s alignment is measured by its accuracy in answering these questions, with a benchmark score set for proficiency.
  • This part of the evaluation assesses whether the model possesses adequate knowledge specific to South Korea as might be expected of someone educated in the Korean school system.

Through these methods, the paper aims to assess how well LM align with both the social values and common knowledge specific to South Korea, providing a comprehensive framework for evaluating the national alignment of LLM.

논문 내의 실험 결과

Experiment Settings

  • The models were tested in a zero-shot manner, which means they were not specifically trained on the KorNAT dataset.
  • Different language models (LMs) were evaluated, including Llama-2, GPT-3.5-Turbo, GPT-4, Claude-1, HyperCLOVA X, PaLM-2, and Gemini Pro. Notably, HyperCLOVA X is a Korean LLM extensively trained on Korean data.
  • Various prompts were used to account for the potential instability of prompting strategies.
  • The responses that did not match with any of the choices were assigned by using another model (gpt-4-1106-preview) for classification.

Social Value Alignment Experiments

  • Social Value Alignment Evaluation Method
    • Social Value Alignment (SVA) measures how closely a model’s responses align with the majority opinion in Korean society.
    • The evaluation was conducted across three scenarios: no adjustment, adjustment with age and gender, and final adjustment (including annual income, residential area, and education level).
    • For each question, a score is calculated based on the alignment between the model’s chosen answer and the response distribution obtained from the survey.
  • Quantitative Results
    • All models achieved higher scores than a neutral ‘All-Neutral’ response, indicating some degree of understanding of social values.
    • In SVA and Aggregated Social Value Alignment (A-SVA), the PaLM-2 model recorded the highest alignment score.
    • HyperCLOVA X was the only model to score higher than ‘All-Neutral’ in Neutral-processed Social Value Alignment (N-SVA).
    • We also calculated the social value alignment under each gender and age group, and the results can be referred to in Appendix D.4 Table 9 of the paper

  • Human Evaluation
    • Additional evaluations were conducted based on the outputs of the model with the highest (PaLM-2) and lowest (Llama-2) social value alignment.
    • The evaluation involved survey participants choosing which model’s responses and reasoning aligned more with their opinions.
    • This evaluation confirmed that models with higher social value alignment scores indeed align more closely with the opinions of Koreans.

Common Knowledge Alignment Experiments

  • Common Knowledge Alignment Evaluation Method:
    • Common Knowledge Alignment assesses how well a model grasps basic knowledge and facts related to South Korea.
    • The evaluation spans multiple subjects covered in the Korean educational curriculum, including Korean language, social studies, Korean history, common sense, mathematics, science, and English.
    • Correct answers for each question are based on Korean textbooks and GED reference materials.
    • Models are scored based on their accuracy in answering these questions.
  • Quantitative Results:
    • Most models scored below the benchmark of 0.6 in all subjects except English.
    • HyperCLOVA X achieved higher scores in most subjects compared to other models, particularly excelling in the Korean language and Korean history subjects.
    • These results indicate the models’ understanding of knowledge and cultural context specific to Korea.

Omitted Responses

  • Omitted Responses Overview:
    • This section deals with instances where the models either refrained from answering a question or provided invalid responses during the Social Value Alignment and Common Knowledge Alignment tests.
    • An analysis of these omitted responses is crucial for understanding the models’ limitations and behavioral patterns.

  • Types of Omitted Responses:
    • Refrained Responses: These occur when a model explicitly states that it will not answer a question. This behavior is significant in the context of social value questions, where a model might choose not to express an opinion on potentially contentious topics.
    • Invalid Responses: These are responses that do not match any of the provided options, thus considered as not aligned or out of scope.
  • Analysis of Models’ Behavior:
    • The analysis revealed variations in the frequency of omitted responses among different models.
    • Notably, some models, particularly GPT-4 and Claude-1, showed a higher tendency to refrain from answering in the social value questions, suggesting a cautious approach to potentially divisive or sensitive topics.
    • The number of invalid responses was also examined, providing insights into each model’s ability to generate relevant and precise answers.

This section highlights the importance of understanding not just when and how models align with human values and knowledge, but also when they choose not to respond or fail to provide valid answers. It sheds light on the behavioral nuances of different language models when confronted with complex or sensitive questions.

Sample Data

  • Below is a sample dataset of our Social Values & Common Knowledge dataset.

    These samples are intended to demonstrate the format of our dataset. For clarity, they include translations into English, but it should be noted that the actual data are in Korean.

    • 데이터셋 전체 공개를 하지 않는 이유

      We created the KorNAT dataset as a benchmark to assess whether the social value and knowledge level of LLMs that will be commercialized in South Korea are suitable for the country. Considering that if the entire dataset is made public, it could undermine its intended role as a fair benchmark due to potential fine-tuning or 'cheating', we have decided not to disclose the full dataset. We release 10 samples of Social Values and 14 samples of Common Knowledge.
