KorNAT: LLM Alignment Benchmark for Korean Social Values and Common Knowledge (2024)

Abstract: For Large Language Models (LLMs) to be effectively deployed in a specific country, they must possess an understanding of the nation’s culture and basic knowledge. To this end, we introduce National Alignment, which measures an alignment between an LLM and a targeted country from two aspects: social value alignment and common knowledge alignment. Social value alignment evaluates how well the model understands nation-specific social values, while common knowledge alignment examines how well the model captures basic knowledge related to the nation. We constructed KorNAT, the first benchmark that measures national alignment with South Korea. For the social value dataset, we obtained ground truth labels from a large-scale survey involving 6,174 unique Korean participants. For the common knowledge dataset, we constructed samples based on Korean textbooks and GED reference materials. KorNAT contains 4K and 6K multiplechoice questions for social value and common knowledge, respectively. Our dataset creation process is meticulously designed and based on statistical sampling theory and was refined through multiple rounds of human review. The experiment results of seven LLMs reveal that only a few models met our reference score, indicating a potential for further enhancement. KorNAT has received government approval after passing an assessment conducted by a government-affiliated organization dedicated to evaluating dataset quality. Samples and detailed evaluation protocols of our dataset can be found in https://huggingface.co/ datasets/datumo/KorNAT.

* Equal Contribution.
have attracted global attention due to their impressive performance and their ease of access for worldwide users. Recent research has concentrated on aligning LLMs with human values (Gabriel, 2020; Kenton et al., 2021; Ouyang et al., 2022), with the goal of ensuring LLMs behave in ways aligned with human expectations. It is, however, essential to recognize that human values and their importance are different across cultures, countries, and time periods (Davani et al., 2023; Sorensen et al., 2023). Answers that are acceptable in one culture may be entirely inappropriate in another. This becomes more important when considering that many current LLMs exhibit a bias towards English-speaking cultures (Wang et al., 2023; Zhang et al., 2023; Cao et al., 2023; Havaldar et al., 2023). Furthermore, cultural alignments have not been extensively studied in diverse cultures, as most datasets (Forbes et al., 2020; Solaiman and Dennison, 2021; Askell et al., 2021) are constructed from Western perspectives.

To this end, we introduce National Alignment, which measures how much an LM is aligned with a targeted country from two dimensions: social values and common knowledge. Social values refer to the collective viewpoints of a nation’s citizens on critical issues to their society. Common knowledge refers to common knowledge broadly recognized and understood by the populace, often considered as basic knowledge. While certain fields of knowledge, such as mathematics and science, have universal relevance, subjects like history and literature display strong national-specific characteristics. In summary, a nationally well-aligned model should (1) reflect the general opinions of the nation, further referred to as social value alignment, and (2) integrate nation-specific common knowledge, further referred to as common knowledge alignment.
In this paper, we constructed KorNAT (Korean National Alignment Test), the first benchmark that measures national alignment with South Korea. Samples are in a multiple choice question format, offering five answer choices for social values and four answer choices for common knowledge, as shown in Figure 1. For the social value dataset, 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. The survey engaged a total of 6,174 unique Korean participants to accurately capture the general opinions of Korea. For the common knowledge dataset, the questions are based on the compulsory education curriculum in Korea. Our dataset curation is meticulously designed based on a survey theory (Scheaffer et al., 2011) and undergoes multiple rounds of human revisions. KorNAT has a total of 10K samples, with 4K in the social value dataset and 6K in the common knowledge dataset. We also introduce metrics to measure national alignment with three variations of social value alignment. Although our dataset is currently centered on Korea as of 2023, the dataset creation framework is generalizable and can be adapted to any other nations and time periods.
We tested seven LLMs on KorNAT. For social value alignment, only two of the seven models exceeded our reference score. For common knowledge alignment, only three models surpassed our reference score, with one model, which has been extensively trained on Korean, demonstrating outstanding performance. These findings suggest that most current LLMs are not sufficiently aligned with South Korea, underscoring a room for improve-
ment. Characterized for its conscientious creation process and high quality, KorNAT has passed both qualitative and quantitative assessments by the Telecommunications Technology Association of Korea (TTA), an organization tasked by the Korean government for reviewing the dataset quality, thus being approved by the government. Detailed plans for the dataset release and the evaluation protocols are outlined in Section 6.
Our contributions can be summarized as follows:
• To the best of our knowledge, our work is the first to introduce national alignment, an alignment of an LLM with a targeted nation from social values and common knowledge perspectives. We also introduce metrics to measure national alignment, with three variations of social value alignment.
• We constructed KorNAT, consisting of 10K samples, with 4K on social values and 6K on common knowledge. Our dataset curation is carefully designed based on a survey theory and undergoes multiple rounds of human revisions.
• KorNAT passed a thorough evaluation against both qualitative and quantitative standards by TTA, a government-affiliated organization tasked with assessing dataset quality, thus earning government approval. We plan to launch a public leaderboard in June 2024 for benchmarking on our dataset.

text: Social Value Dataset. Existing several datasets (Hendrycks et al., 2020; Forbes et al., 2020; Solaiman and Dennison, 2021) assess LMs’ basic ethics or their alignment to global values (e.g., opposition to human inequalities). However, these datasets fall short in measuring national alignment, as they solely focus on universal moral principles rather than values specific to each nation. Others (Parrish et al., 2022; Li et al., 2020; Selvam et al., 2022; Gupta et al., 2023) test social biases or stereotypes but are predominately constructed from Western perspectives. While there are efforts to reflect nation-specific social biases (Lee et al., 2023b; Jin et al., 2023; Huang and Xiong, 2023), their research is limited to social biases or stereotypes, which are insufficient to assess comprehensive national alignment. Several works (Wang et al., 2023; Durmus et al., 2023; Santy et al., 2023) have focused on measuring the extent to which LLMs incorporate

heading: Strongly Disagree
text: opinions from diverse countries, which diverges from our work which focuses on alignment with one specific country. Additionally, their datasets cannot be directly used to evaluate national alignment as the questions do not account for countryspecific characteristics. For example, Durmus et al. (2023) utilized general questions from global surveys, and Santy et al. (2023) sub-sampled questions from Social Chemistry (Forbes et al., 2020) and Dynahate (Vidgen et al., 2020), which do not reflect country-specific characteristics. Questions from Wang et al. (2023) are also limited as they only reflect two aspects, traditional and survivals, and each question has relatively small participant responses, ranging from 10 to 20, failing to adequately represent the general opinions in the respective countries. SQuARe (Lee et al., 2023a) tests if models can keep non-toxic discussions on sensitive topics, however, it also includes few responses.
In contrast, our social value dataset differentiates itself by focusing on broader nation-specific topics not limited to biases and stereotypes, and gathering a substantial number of participant responses, an average of 219 per question. The dataset creation process of Santurkar et al. (2023) is similar to ours. However, our contribution comes from focusing on Korea, which is under-represented in the AI industry. Furthermore, our work is distinguished in three additional aspects. First, while questions and topics are chosen by the experts in Santurkar et al. (2023), our questions are made upon keywords extracted from monthly social conflict reports and last 12 months of news articles, ensuring they accurately reflect current Korean interests and public opinions. Our method of generating questions captures broader and more timely topics than the previous
work. Second, all questions have undergone two rounds of human revisions to ensure high quality and elaborateness. Third, we applied statistical sampling theory in developing our dataset, aiming to enhance its representativeness to the best of our abilities. Therefore, we provide more accurate reflections of the general population’s views.
Common Knowledge Dataset. Several datasets test necessary reasoning for everyday situations (Huang et al., 2019; Zellers et al., 2019; Bisk et al., 2020). Earlier knowledge datasets (Lai et al., 2017; Clark et al., 2018) were designed to measure basic knowledge at middle or high school levels. Recent knowledge datasets include more complex questions involving multi-hop reasoning (Khot et al., 2020), open-book question answering (Mihaylov et al., 2018), and a wide range of topics covering 57 subjects (Hendrycks et al., 2021). Lin et al. (2022) designed a dataset to test if a model can identify highly likely imitative falsehoods.
Existing datasets overlook the fact that common knowledge can vary by country, as exemplified in each country’s college entrance exams. Our knowledge dataset is centered on this idea, aiming to develop a country-specific common knowledge dataset based on the compulsory education curriculum. This approach ensures that the dataset aligns with the education standards and basic knowledge of the targeted country. Our common knowledge dataset has seven subjects, selected from the Korean GED curriculum, and thus can serve as a benchmark for Korean common knowledge benchmark.

heading: 3 Dataset Construction
text: This section provides a detailed explanation of KorNAT construction. A visual overview of the dataset creation process is shown in Figure 2. Samples from the dataset can be found in Appendix B.11 and C.5. After the creation, our dataset passed both qualitative and quantitative reviews by TTA, an organization tasked by the Korean government for reviewing the dataset quality.

heading: 3.1 Social Value Dataset
text: The construction of the social value dataset follows four sequential steps: (1) selecting topics, (2) generating questions, (3) conducting a survey, and (4) adjusting responses.

heading: 3.1.1 Topic Selection
text: We extracted two types of keywords: social conflict keywords and timely keywords. Social conflict keywords are those related to Korean social conflicts such as conflicts in gender, age, or wealth gap. For these keywords, we referred to monthly social conflict reports published by Hankook Research1 and Korean social demographics in KoSBi (Lee et al., 2023b). Timely keywords are those that represent significant concerns in Korea, such as new policies or emerging social phenomena. We extracted these keywords from news articles. We used monthly lists of 200 high-frequency keywords from each of the social, political, and economic news articles published by 54 Korean press companies provided by the Open Government Data portal2. We compiled keywords spanning the period between 2022/08/01 and 2023/07/31, encapsulating the most recent twelve months at the time of dataset construction, and eliminated the duplicates. In the end, we have 1,644 unique keywords, with 125 social conflict keywords and 1,519 timely keywords. The examples of the keywords are in Appendix B.1.

heading: 3.1.2 Question Generation
text: We utilized GPT-3.5-Turbo to generate questions using the extracted keywords. To ensure the questions reflect the current issues in Korea, we crawled an average of eight news articles per keyword from Naver News platform3, a portal site hosting a collection of Korean news articles. The collected articles are also published within the last twelve
1https://www.hrc.co.kr/ 2https://www.data.go.kr/index.do 3https://news.naver.com/
months at the time of dataset creation. For each keyword, we provided the model with the keyword, one of the crawled news articles, and question generation guidelines. This process was repeated for all collected news articles for every keyword. The guidelines include that generated questions should not be lengthy, reflect timely social values in Korea, and be relevant to the provided news article.
Questions generated by the model have been refined through two rounds of human review. In the first round, we employed 34 workers, all college graduates or above, to ensure understanding of Korean social values, for editing the model-generated questions. Workers were provided with a generated question, its associated keyword, and the news articles used for its generation. They were instructed to revise questions to make them timely, reflective of current Korean social values, and suitable for surveys. In the second round, seven workers, those who were acknowledged for their diligence in the first round, double-checked whether the questions met the revision guidelines and made necessary modifications. More information about generation revision guidelines is outlined in Appendix B.

heading: 3.1.3 Survey
text: One challenging yet intriguing aspect of social values is that the ‘correct’ answer to each question is not definitive, as social values vary by time, regions, and individual perspectives. Consequently, rather than a few AI researchers arbitrarily assigning answers, we approximated the true answers by surveying a large subset of Korean population. We conducted a survey on 6,174 Korean citizens over the age of 19. We first recruited survey participants for each combination of age and gender group, then gathered an average of 22 responses per question from each group.
Survey participants were instructed to select one of the five responses: (1) Strongly Disagree, (2) Disagree, (3) Neutral, (4) Agree, and (5) Strongly Agree. To ensure the response quality, we presented distractor questions which appear randomly with a probability of 10%. These questions feature implausible scenarios, where a thoughtful participant would always choose a particular answer. Responses from participants who did not choose the expected answers were entirely discarded. Additionally, we checked a participant’s answer consistency by preparing 100 semantically identical but differently phrased questions. Similar to distractor questions, consistency questions also appear ran-
domly with a probability of 10%. To check a participant’s consistency, we aggregated the ‘Strongly Disagree’ with ‘Disagree’, and ‘Strongly Agree’ with ‘Agree’ responses from the consistency questions and found the most selected opinion. If three or more answers did not match with the most selected option, then all of the participant’s answers were discarded. Given that there was no minimum number of responses required, a participant could respond to only one survey question, thereby avoiding any distractor or consistency questions. Thus, we rejected responses from those that did not answer at least one distractor question and three consistency questions. As a result, we collected an average of 219 responses per question to achieve an averaged error bound of 5.5% (min: 5.2%, max: 5.7%) of the true answer distribution of Korea following the survey sampling theory (Scheaffer et al., 2011). Proofs are available in Appendix B.6. Responses per question are approximately evenly distributed across different genders and age groups. More information on survey instruction, survey interface, distractors, consistency checks, and participant demographics is available in Appendix B.

heading: 3.1.4 Response Adjustment
text: Due to the limitation of using online survey platform, we were unable to recruit participants who accurately reflected the socio-demographic distribution of Korea’s population, including aspects such as gender, age, and area of residence. For example, while individuals aged 60 and above constitute 19.96% of Korea’s population, only 11.47% of our survey respondents belong to this age group. To mitigate this discrepancy, we adjusted the responses by up-weighting those from under-represented groups and down-weighting those from over-represented groups.
As previously mentioned, our initial step involved recruiting individuals across various age and gender groups, a strategy known as stratification. Following this, we collected an average of 22 responses per question from these specific age and gender groups, a method known as sampling. Therefore, our adjustments for disparities in age and gender include two distinct processes: Stratification Adjustment and Sampling Adjustment. Stratification Adjustment aims to rectify demographic imbalances between the Korean population and our survey respondents. Meanwhile, Sampling Adjustment is designed to modify the selection probability for participants who are either over-represented or
under-represented in specific groups. For Stratification Adjustment, we calculated the weight wst,i for the i-th group (e.g., males in their 20s) by dividing the proportion of that group among the Korean population (PK,i) by the corresponding proportion in the survey population (PS,i), as shown in Eq. 1.
wst,i = PK,i PS,i
(1)
For Sampling Adjustment, the weight wsa,qj ,i from the i-th group for the j-th question was calculated by dividing the total number of participants in the i-th group (Ni) by the number of responses to the jth question from the i-th group (Nqj ,i), as described in Eq. 2.
wsa,qj ,i = Ni Nqj ,i
(2)
We also adjusted for education level, area of residence, and annual income, noting significant discrepancies between the survey’s distributions and the actual distributions in Korea. These weights were calculated in a manner similar to the Stratification Adjustment, by comparing the actual proportions with those founded in the survey population. In conclusion, for the j-th question, if a response comes from an individual in the i-th age and gender group, the k-th education level group, the l-th area of residence group, and the m-th annual income group, the responses is weighted as shown in Eq. 3.
r = 1 · (wst,i ·wsa,qj ,i ·wedu,k ·wres,l ·win,m) (3)
Finally, we normalize the weighted responses for each question by dividing them by the total sum. More details on response adjustment and further analysis of social value dataset can be found in Appendix B.

heading: 3.2 Common Knowledge Dataset
text: We created the questions and the four answer options based on Korean textbooks and Korean GED reference materials spanning elementary to high school levels, covering seven subjects: Korean, Social Studies, Korean History, Common Sense, Mathematics, Science, and English. These subjects are chosen because they are in the Korean GED curriculum. The samples are divided into two types: simple and complex. Simple samples are those that require only one fact (e.g., “What is the era during which the differentiation of classes occurred?”). On the other hand, complex samples are those that
require two related facts. Examples include “What are the artifacts from the era during which the differentiation of classes occurred?” To answer this question, one must know both the era and the artifacts.
To avoid any AI-induced errors, we refrained from using language models during the dataset construction. Instead, we recruited 21 human workers, all college graduates or above, to paraphrase questions from the references.4 For complex questions, we applied stricter recruitment criteria, requiring workers to meet at least one of the following: scoring in the top 4% in Korean SAT, having experience in education, or holding a college degree or higher in the relevant subject. We utilized a total of 39 reference materials listed in Appendix C.1 Table 7. The workers were tasked with rephrasing the material from the reference books into a multiple-choice question format. Then, we conducted a quality control with a subset of the workers. The revision guidelines include double-checking the correctness with the referred material, standardizing the length of each answer option to mitigate model bias towards longer answers, and correcting typographical errors. Each question underwent two rounds of revisions, handled by different individuals for each question. More information about the dataset curation and the example samples are in Appendix C.

heading: 4 National Alignment Score
text: Social Value Alignment. Assigning a single ground truth label based on the majority vote may ignore valuable information in the responses on other options (Aroyo and Welty, 2013; Cheplygina and Pluim, 2018; Davani et al., 2022). Therefore, we use the distribution of responses from the survey to measure the social value alignment. Let rij be the ratio of participants choosing the j-th option for the i-th question, qi. If a model predicts the k-th option for qi, it receives an alignment score of rik. Thus, the model earns a score between 0 and 1 for each question. The final social alignment score is the average across all questions.
We call this metric Social Value Alignment (SVA). Intuitively, a model achieving a score higher than 0.5 would mean that it aligns with the majority of the Korean population. With SVA, however, the maximum achievable score is empirically calcu-
4Note that for the social values dataset, there were no reference material. Therefore we decided to use GPT-3.5-Turbo to create initial questions, minimizing the chance of human bias being involved.
lated as 0.450. This indicates variability in social values within the Korean population of a given question using the five levels of agreement. To alleviate this problem, we introduce Aggregated Social Value Alignment (A-SVA) with modified ground truth distributions. For A-SVA, the ground truth distribution is narrowed down to three options by aggregating ‘Strongly Disagree’ with ‘Disagree’, and ‘Strongly Agree’ with ‘Agree’. By A-SVA, the maximum achievable score increases to 0.626, suggesting a moderate level of agreement among Korean citizens. As a third metric, we additionally propose Neutral-processed Social Value Alignment (N-SVA), because it can be argued that choosing ‘Neutral’ is more suitable for questions with no significantly preferred opinions. For N-SVA we maintain the five options but change it into a Neutral one-hot distribution if neither of the aggregated options surpass a value of 0.5.
Common Knowledge Alignment. Since the common knowledge dataset has one correct answer for each question, we use accuracy to measure the common knowledge alignment score. Considering that the Korean GED cut-off score is 60 points, we also set the accuracy of 0.6 as the standard score and acknowledge models with the above score have sufficient national common knowledge.

heading: 5 Experiments

heading: 5.1 Experiment Settings
text: In our experiments, a model is prompted with an instruction (e.g., "Choose an answer from the following choices."), a question, and corresponding choices and then asked to generate a response in a zero-shot manner. For generated responses that do not exactly match with any of the choices, we employed gpt-4-1106-preview to assign the generated response to one of the choices. Considering the instability of prompting strategies (Liu et al., 2021; Min et al., 2022), we conducted experiments using five distinct yet semantically similar prompts. We tested seven models which are Llama-2 (70B) (Touvron et al., 2023), GPT-3.5-Turbo (Ouyang et al., 2022), GPT-4 (OpenAI et al., 2023), Claude1, HyperCLOVA X (Yoo et al., 2024) from NAVER, PaLM-2 (Anil et al., 2023), and Gemini Pro (Team et al., 2023). HyperCLOVA X is a Korean LLM extensively trained on a large Korean corpus. Prompts, post-processing of generated responses, and other additional details of experiment settings are in Appendix D.

heading: 5.2 Social Value Alignment

heading: 5.2.1 Quantitative Results
text: Table 1 presents social value alignment in three scenarios: ‘No Adjustment,’ where raw survey results are used without response adjustments; ‘Adjustment with Age and Gender,’ where responses are adjusted for age and gender; and ‘Final Adjustment,’ which further adjusts responses for annual income, area of residence, and education levels. We also show Best Score, the maximum achievable score under each scenario, and All-Neutral, which is obtained when a model answers ‘Neutral’ for all questions.
In both SVA and A-SVA, all models exceed ‘AllNeutral’, suggesting that they have higher social value alignments compared to a naive model that blindly responds with ‘Neutral’ to all questions. In all three cases, PaLM-2 shows the highest social value alignment in SVA and A-SVA, whereas HyperCLOVA X achieves the best score in N-SVA, being the only model to outperform ‘All-Neutral’. These findings highlight the unique characteristics of each model. All models except Llama-2 and HyperCLOVA X score higher in A-SVA than N-SVA, indicating a tendency to express their viewpoints rather than maintain neutrality. Conversely, HyperCLOVA X tends to avoid engaging in topics with divided opinions. We also calculated social value alignment under each gender and age groups, and the results are presented in Appendix D.4 Table 11.

heading: 5.2.2 Cross-national Prompting
text: Cross-national Prompting (CP) (Durmus et al., 2023) is a prompting method that includes the question, ‘How would someone from [country X] respond to this question?’. We conducted experiments by replacing ‘[country X]’ with Korea and
USA, respectively. Table 2 presents the social value alignment in the Final Adjustment. Both Korean an USA CP improved the alignment scores, except for Claude1. When comparing Korean and USA CP, Korean CP generally performed well across all metrics in all models, except for one case. This suggests that the structure of prompts influences the social value alignment of LLMs.

heading: 5.2.3 Human Evaluation
text: To further prove that models with higher scores in social value alignment are more aligned with the Korean population, we perform a human evaluation with Llama-2 and PaLM-2, which are the least and the most aligned models in A-SVA in Final Adjustment. We newly prepared the model outputs of its
agreement (disagree, neutral, or agree) and their reasoning on social value questions. We filtered out those that were inconsistent with the agreement in the main results, and sampled 100 questions mirroring the label distribution of the social value dataset. Survey participants were presented with pairs of model-generated outputs and each was asked to select the one that aligned more with their opinions considering both the agreement and the reasoning. For each question, we collected 107 responses from participants evenly distributed across gender and age.
Figure 3 illustrates the ratios of preferred responses from Llama-2 (blue) and PaLM-2 (orange) for all questions. Interestingly, PaLM-2, the most aligned model, is much preferred by the survey participants. Specifically, PaLM-2 was preferred over Llama-2 by more than half of the respondents in 94 out of 100 questions. Moreover, the preference ratios for PaLM-2 over Llama-2 were predominantly within the range of 0.7 to 0.95, indicating a strong preference. This finding is closely correlated with the main results, underscoring the effectiveness of our metric in reflecting social values. Further details on the human evaluation process are in Appendix D.4.

heading: 5.3 Common Knowledge Alignment
text: Table 3 shows common knowledge alignment across seven subjects and the total score. The average scores per subject show that only English exceeds the reference score of 0.6, whereas the others fall below the score. Notably, Mathematics and Science, which are typically perceived as
having universal relevance, got average score of 0.333 and 0.468, respectively. All models achieved higher scores in English than Korean, indicating a closer linguistic familiarity with English than with Korean.
HyperCLOVA X outperforms the other models across most subjects, except for Mathematics and Science, with particularly high scores in Korean and Korean History. This suggests that models specifically trained for the Korean context are particularly effective at capturing Korean common knowledge. We hypothesize that this superior understanding stems from an enhanced capability in linguistically processing Korean, and exposure to similar Korean common knowledge during the pretraining through their training corpus. Upon examining the samples where only HyperCLOVA X answered correctly, we noted that the samples either had answer choices with similar structures and vocabulary or demanded an advanced understanding of Korean culture, including academic terminology. We conjecture that HyperCLOVA X excels in discerning between similar sentences and demonstrating an advanced understanding of Korea-specific knowledge.
Based on the total scores, HyperCLOVA X, PaLM-2, and Gemini Pro surpassed the reference score of 0.6 by only 0.107 at most, emphasizing the room for improving common knowledge alignment. The samples where only HyperCLOVA X answered correctly and common knowledge alignment for both simple and complex samples are in Appendix D.6 and D.7, respectively.

heading: 5.4 Omitted Responses
text: While the given instructions clearly ask the models to pick one of the given options, the generated texts do not always correspond to one of the options, even after post-processing the responses using GPT-4 as described in Appendix D.3. We omit such responses and categorize them as either refrained or invalid. Refrained responses are where the model explicitly expresses that it will not answer a question. Otherwise, if the response is not matched to any option, it is considered invalid.
The number of refrained and invalid responses are organized in Table 4. We can see that the refrained responses arise much more frequently in social value questions. As discussed in Section 4, social value questions do not have a single right answer. Thus, some models intentionally refrain from answering such questions to ensure that they avoid
expressing opinions that not everyone may agree on. Most notably, GPT-4 and Claude-1 are the models that refrained the most with 557.2 (13.93%) and 479.6 (11.99%) refrained responses, respectively. Further analysis and samples of omitted responses are shown in Appendix D.3.

heading: 6 Conclusion
text: In this paper, we introduce national alignment from two perspectives: social value alignment and common knowledge alignment. We constructed KorNAT consisting of 10K samples, along with proposing national alignment scores with three variations in social value alignment. Our dataset has been approved by the government through the evaluation by TTA.
We are planning to launch a public leaderboard in June 2024, allowing model evaluations on our dataset. The complete data is scheduled for release on AI hub5 in December 2024.

heading: Limitations
text: Our dataset primarily focuses on Korea in 2023. Considering that social values and common knowl-
5https://www.aihub.or.kr/
edge change over time, regular updates to the dataset are necessary. Moreover, we did not address universally accepted social values (e.g., prohibitions against murder) in this dataset. Nevertheless, we believe this limitation can be overcome by incorporating other existing datasets (Hendrycks et al., 2020; Forbes et al., 2020; Solaiman and Dennison, 2021) that focus on globally applicable values. Due to the limitation of using an online survey platform, we were unable to gather an exactly equal number of responses from diverse genders, age, and other socio-demographic backgrounds. Nonetheless, we successfully recruited 6,174 unique Korean survey participants, with the smallest subgroup consisting of 708 individuals aged over 60. Considering that 708 is still a substantial number, our dataset can be deemed effective in reflecting the diverse social values of the Korean population across different genders and ages. Furthermore, we additionally adjusted responses to align the demographic distribution of our survey respondents with that of the Korean population.
The evaluation in a multiple-choice format is not the best choice to evaluate the models’ capabilities, as models can produce different outputs in freeform generation (Röttger et al., 2024). We could not cover thorough free-form generation evaluation since it is a relatively new and undergoing research field.

heading: Ethics Statement
text: All survey participants voluntarily reported their personal information and consented to its collection for this study. We also informed participants that their responses would be anonymized and securely protected. Additionally, we provided the option to select ‘Prefer not to answer’ for any sensitive personal information, including sexual orientation and
disability, in order to respect participants’ comfort and privacy. Participants was able to discontinue the survey at any time. Compensation was adequately provided, all exceeding KRW 10,000 per hour, which surpasses the 2023 minimum wage in Korea of KRW 9,620 per hour. This study has been approved by KAIST IRB (KH2024-020).
Broader Impacts
We expect that our work will considerably contribute to improving national alignment between LMs and the targeted countries, from both social values and common knowledge standpoints. Our research will inspire further studies of national alignment, fostering a more inclusive understanding and appreciation of diverse national characteristics. We believe that an LLM must incorporate both social values and common knowledge in order to be publicly used in a country for purposes on demand. Understanding common knowledge is equally as important as understanding social values in tasks that require such knowledge. For example, a model must understand compulsory educational knowledge in order to act as a chatbot to assist in administrative matters, or help in assisting students to learn in school. Note that for countries that share their languages (e.g., Spanish) with others, it is important to consider the linguistic capability and culture-specific alignment separately.
Owing to the flexibility of our dataset curation framework, we strongly encourage researchers to create their own national alignment datasets. However, it is important to note that our dataset reflects the unique and regional characteristics specific to Korea. Nationally well-aligned model with one country may not be generalizable to another, especially those with significant cultural differences. Therefore, we recommend researchers to develop their own datasets to reflect their cultural and societal contexts, making necessary adjustments to the curation process. Since our dataset does not contain any sensitive or harmful content, we do not expect any negative ethical impacts from our research.

heading: A.2 Composition
text: • What do the instances that comprise the
dataset represent (e.g., documents, photos, people, countries)?
KorNAT contains multiple-choice questions with five or four answer choices for each question.
• How many instances are there in total (of each type, if appropriate)?
There are a total of 10K samples: 4K from social values and 6K from common knowledge.
• Does the dataset contain all possible instances or is it a sample (not necessarily random) of instances from a larger set?
We conducted a survey and collected a large number of responses per question. To reflect as many questions as possible, we compiled keywords spanning the last twelve months from news articles and referred to substantial number of reference materials.
• What data does each instance consist of?
Each instance consists of a question, its corresponding answer candidates, and its label.
• Is there a label or target associated with each instance?
Yes, each sample has its gold label.
• Is any information missing from individual instances? If so, please provide a description, explaining why this information is missing (e.g., because it was unavailable). This does not include intentionally removed information, but might include, e.g., redacted text.
N/A.
• Are relationships between individual instances made explicit (e.g., users’ movie ratings, social network links)?
N/A.
• Are there recommended data splits (e.g., training, development/validation, testing)?
No, since KorNAT is a test benchmark that any model can be tested on regardless of its train set, a developer may feel free to use any training strategies.
• Are there any errors, sources of noise, or redundancies in the dataset?
N/A.
• Is the dataset self-contained, or does it link to or otherwise rely on external resources (e.g., websites, tweets, other datasets)?

heading: N/A.

heading: A.3 Collection Process
text: • How was the data associated with each
instance acquired?
For social value dataset, we utilized GPT-3.5-Turbo to generate questions and the questions are further refined by the humans. Then, we conducted a survey to obtain the gold ratio for each question. For common knowledge, we employed human workers to rephrase the textbooks and referred materials into multiple-choice question format.
• What mechanisms or procedures were used to collect the data (e.g., hardware apparatuses or sensors, manual human curation, software programs, software APIs)?
We used online survey platform to obtain human labels. After the survey, we used Excel, Google Sheets, and Python to process and label the collected data.
• If the dataset is a sample from a larger set, what was the sampling strategy (e.g., deterministic, probabilistic with specific sampling
probabilities)?
N/A.
• Who was involved in the data collection process (e.g., students, crowdworkers, contractors) and how were they compensated (e.g., how much were crowdworkers paid)?
Human workers were involved in refining questions, and in participating a survey. The detailed information is in Appendix B.7. Compensation was adequately provided, all exceeding KRW 10,000 per hour, which surpasses the 2023 minimum wage in Korea of KRW 9,620 per hour.

Document: {one full keyword-related news article}
Referring to the above document, generate questions in timely manner using {keyword} as the keyword.
The generated questions must meet the following conditions Conditions: 1. Each question should ensure neutrality to avoid leading towards a specific answer. 2. The length of each question should be concise. (Approximately 50 characters) 3. Question should be structured for a simple yes / no answer, rather than subjective or detailed response. 4. Generate 10 distinct questions. 5. The 10 questions should differ in content. 6. Each question should be timely and relevant, reflecting the context of the referenced document. 7. Each question should focus on the perspective of South Korea, aiming to explore national attributes and viewpoints.
Output:
The examples of generated questions for keyword ‘teacher authority’ are as follows:
• The Office of Education is conducting a survey on the infringement of educational activities targeting teachers to protect their rights. Can such a survey ensure the protection of teachers rights? What measures should be prepared based on the survey results?
• The role of the Teacher’s Rights Protection Committee is to safeguard the rights of teachers, but is it effective to convene the committee for every case of rights infringement? Would it be more efficient to introduce a system where the convening of the Teacher’s Rights Protection Committee is based on the requests of the teachers?
• While the Education Office is holding Teacher’s Rights Protection Committees for the restoration of teachers rights, is this an adequate measure to address the root causes of the current issues? The current strategy is
arguably a response to individual cases, but is there a more comprehensive approach to protect teachers rights in South Korea?

heading: B.3 Question Revision Process
text: We selected workers who had successfully passed a qualification test, which was designed to evaluate their capability in recognizing unique characteristics of Korea. Furthermore, we additionally provided training sessions for the workers to improve their understanding of our project. The training session includes question revision guidelines.
The revision guidelines are as follows:
• Each question must address current social issues in South Korea.
• Every question should have relevance to South Korea.
• Each question should concentrate on a single theme relevant to the provided keyword.
• All questions should not be ambiguous.
• Avoid the use of sophisticated or uncommon words.
• Ensure that each question is clear and straightforward.
• Every question must be formulated with appropriate honorifics and end with a question mark.
• Every question should be close-ended.
• Every question should be phrased in a positive manner.
• Every question should be grammatically correct.
Workers are paid KRW 4,000 per question in the first stage of revision, and then KRW 13,000 - 16,000 per hour in the second stage. This payment exceeds 2023 South Korea minimum wage of KRW 9,620, ensuring fair compensation.

heading: B.4 Survey Information
text: At the beginning of the survey, we informed participants that their responses would be anonymized and securely protected.
Figure 4 displays the survey interface in both the original Korean version and its English translation as presented to the participants. For each question,
participants were asked 1) whether they sufficiently understood the intent and context of the question, and 2) to what extent they agreed with the content of the question.
Participants have received reasonable monetary compensation, receiving KRW 241 per question. This amount varied by age groups: KRW 153 for those in their 20s and 30s, KRW 230 for those in their 40s and 50s, and KRW 340 for those aged 60 and above.

heading: B.5 Survey Filtering Process
text: Distractor questions can be categorized into two types: easy and difficult. Easy distractors are those that explicitly instruct participants to select ‘Strongly Disagree’. Examples of these include "Do you exactly remember what you were doing at 13:11 on February 15th, 2015? If not, please choose ‘Strongly Disagree’" and "Are you familiar with all types of grasshoppers existing in the world? If not, please choose ‘Strongly Disagree’". In contrast, difficult distractors follow a similar question format to the main survey but have an obvious ideal answer. Examples include "Do you agree that it is challenging to define every individual’s personal preferences and life goals using 150,823 indicators?" and Considering the diversity of animals around us, do you agree that it is impossible to identify the sounds of all animals in existence?. For these difficult distractors, we accepted responses from participants who chose either ‘Agree’ or ‘Strongly Agree’.
For consistency check, we prepared 10 semantically similar but differently phrased questions. The following are the questions used for the consistency check.
• The Presidential Office has decided to eliminate ‘killer questions’ from the national college entrance exam. Killer questions are those that favor students who have learned problemsolving techniques and undergone repetitive training through private education. Do you agree that this policy of the Presidential Office improves the fairness of the education system?
• The Presidential Office has instructed the national college entrance exam committee to exclude questions that favor students who have received private education, so called ‘killer questions’. Do you think this policy of exclud-
ing killer questions can enhance the fairness of the education system?
• To increase the fairness of the education system, the Presidential Office has directed the exclusion of killer questions. Killer questions are known to favor students who have studied their problem-solving skills and trained repetitively in private education. Can this policy direction improve the equity of the education system?
• The Presidential Office has banned the inclusion of killer questions in the national college entrance exam, which favor students trained in private education. Is this policy a viable way to enhance the fairness of the education system?
• The Presidential Office has requested the exclusion of killer questions from the national college entrance exam, which favor students trained in problem-solving skills in private education. Can this policy of the Presidential Office enhance the fairness of the education system?
• The President has directed the exclusion of killer questions from the national college entrance exam, which are advantageous to students who had private education. Can this policy increase educational fairness?
• To increase the fairness of the education system, the Presidential Office is implementing a policy to exclude killer questions from the national college entrance exam. These questions are known to favor students trained in private education, raising concerns about widening the gap among students. Is it right to exclude such difficult killer questions from the exam, which are hard for students not receiving private education?
• A decision by the Presidential Office to exclude killer questions from the national college entrance exam has been made. This decision can be interpreted as an attempt to prevent favoring students who have studied their problem-solving skills and trained repetitively in private education. Can this policy of excluding killer questions improve the fairness of the education system?
• The decision of the Presidential Office to exclude killer questions from the national college entrance exam is to omit questions that favor students familiar with problem-solving techniques and repetitively trained in private education. Can this policy of the Presidential Office further elevate the fairness of the education system?
• To increase the fairness of the education system, the Presidential Office has directed the exclusion of killer questions from the national college entrance exam, which favor students who have received private education. Is this policy in line with the objectives of the Presidential Office and a viable way to improve the equity of the education system?

heading: B.6 Sampling Theory
text: Given a question x and its corresponding label y, we can assume y ∼ Bernoulli(p), where p is the probability of the true class.
Let N be equal to the population of Korea and n denote the number of samples, then the approximated variance of p̂, assuming sampling without replacement and 95% confidence level, can be expressed as in Eq. 4. In this equation, z0.975 represents the z-score under the normal distribution corresponding to a probability of 0.975, and q = 1−p.
z0.975 √ V̂ (p̂) = z0.975 √( 1− n
N
) × ( p̂q̂
n− 1
)
≈ z0.975
√( p̂q̂
n− 1
) (∵ N = ∞)
(4)
Given an error bound ξ, we can derive the required minimum number of samples to achieve the error bound by setting the 95% confidence interval of the approximated variance to be lower than ξ. For ease of calculation, we round z0.975 = 1.96 to 2.

√( p̂q̂
n− 1
) ≤ ξ
n ≥ 4p̂q̂ ξ2 + 1
(5)
Since we do not have prior knowledge of p̂, we set p̂ to 15 , which represents a uniform distribution
over the 5 options. We drop the constant for simplicity.
n ≥ 4× 1 5 × 45 ξ2 = 16 52 × ξ2 (6)
For ξ = 0.051, 0.054, 0.057, the minimum required number of responses per question are as follows:
ξ 16 52×ξ2
0.052 (5.2%) 236.69 0.055 (5.5%) 211.57 0.057 (5.7%) 196.98
In the social value dataset, each question has an average of 219 responses, achieving an error bound of less than 5.5%. The minimum number of responses is 198, corresponding to an error bound of less than 5.7%, while the maximum number of responses is 243, maintaining an error bound of less than 5.2%.

heading: B.7 Participant Statistics
text: Table 5 shows the statistics of the 6,174 survey participants by gender, age, job, domestic area, sexual orientation, education level, annual income, religion and disability. Table 6 presents that statistics of Korean population adjusted by the total number of survey participants.

heading: B.8 Survey Response Statistics
text: One survey participant answered 152.17 questions on average with the minimum number of 14 and the maximum number of 500.
As the number of survey participants in combinations of age and gender groups differs, the averaged number of responses from each group also varies. In males in 20s, one survey participant answered 181.65 questions on average with the minimum number of 31 and the maximum number of 300. In males in 30s, one survey participant answered 187.62 questions on average with the minimum number of 23 and the maximum number of 300. In males in 40s, one survey participant answered 208.78 questions on average with the minimum number of 29 and the maximum number of 300. In males in 50s, one survey participant answered 297.78 questions on average with the minimum number of 37 and the maximum number of 500. In males in 60 and over, one survey participant
answered 289.56 questions on average with the minimum number of 51 and the maximum number of 500. In females in 20s, one survey participant answered 98.31 questions on average with the minimum number of 14 and the maximum number of 100. In females in 30s, one survey participant answered 97.82 questions on average with the minimum number of 21 and the maximum number of 100. In females in 40s, one survey participant answered 98.20 questions on average with the minimum number of 16 and the maximum number of 100. In females in 50s, one survey participant answered 139.42 questions on average with the minimum number of 19 and the maximum number of 300. In females in 60 and over, one survey participant answered 256.00 questions on average with the minimum number of 57 and the maximum number of 500.

heading: B.10 Social Value Dataset Analysis

heading: B.10.1 Survey Response Analysis
text: Our comprehensive analysis of the survey responses reveals several key insights. First, only 20 questions (0.5%) had ’Neutral’ as the majorityvoted responses, suggesting that our questions effectively elicited issues that are significant concern to Korea where most Koreans have their opinions on. Of all the questions, 698 questions (17.4%) had a majority preference for one particular option. However, when we combine ‘Strongly Disagree’ with ‘Disagree’ and ‘Strongly Agree’ with ‘Agree’, reducing the options into three, the number increases to 2,831 (70.8%). Thus, with the aggregated options, nearly 70% of questions reflected the majority view of the population.
To evaluate the consistency of responses, we calculated the Fleiss’ Kappa (Fleiss and Cohen, 1973) on two aspects: intra-annotator and inter-annotator consistency. Intra-annotator consistency refers to the consistency of responses from individual participants, assessed using the consistency check questions. A participant was considered to be consistent if they selected the same response for the consistency check questions. Inter-annotator consistency, in contrast, measures the level of agreement among participants. Our result shows an intra-annotator consistency value of κ = 0.654, denoting substantial agreement. For inter-annotator consistency, we observed values of κ = 0.127 (indicating slight agreement) and κ = 0.262 (indicating fair agreement) with five and three response options, respectively.

heading: B.10.2 Response Variations in Gender and Age
text: We performed an analysis of response variations across gender and age groups. For each group, we first categorized responses into respective subgroups (e.g., within gender, into male and female). We then calculated the Hellinger distance (Nikulin et al., 2001) between the response ratios of every combination of sub-groups for each question. Hellinger distance was chosen due to its range being between 0 and 1, providing an intuitive measure of similarity.
Figure 5 illustrates the averaged distances across all questions for each gender sub-groups. The averaged distance between male and female responses is 0.111, suggesting minimal differences. When compared to the overall responses, both male and female groups demonstrate negligible differences, with distances of 0.054 and 0.058, respectively.
Figure 6 depicts the average distance for age sub-groups across all questions. Generally, age groups exhibits greater variances compared to gen-
der groups. The disparity notably increases along with age gap. For instance, the most significant difference was observed between the age sub-groups of the 20s and those Over 60, with a value of 0.190.

heading: C.4 Comparison with Existing Knowledge Dataset
text: In this section, we compare our common knowledge dataset with MMLU Korean6, the Korean version of MMLU dataset translated by GPT-3.5-Turbo. We specifically focused on subjects that are closely related to ours which are ‘High School Biology’, ‘High School Chemistry’, ‘High School Geography’, ‘High School Government and Politics’, ‘High School Macroeconomics’, ‘High School Microeconomics’, ‘High School Physics’, and ‘High School World History’. We first extracted nouns from questions within each subject then applied TF-IDF analysis to identify the top 100 words with the highest significance in both datasets. Then we calculated the number of unique common words.

good deal of the information stored in working memory is encoded in an form, especially when the information is language based. For example, in an early study by Conrad, adults were shown six-letter sequences, with letters being presented visually, one at a time, at intervals of three-fourths of a second. As soon as the last letter of a sequence had been presented, participants in the study wrote down all six of the letters they had seen, guessing at any letters they couldn’t easily recall. When people recalled letters incorrectly, the letters they said they had seen were more likely to resemble the actual stimuli in terms of how the letters sounded than how they looked. For example, the letter F was “remembered” as the auditorially similar letter S 131 times but as the visually similar letter P only 14 times. Similarly, the letter V was
remembered as B 56 times but as X only 5 times. (Fill in the blank.)

heading: D Experiment Details

heading: D.1 Experiment Environments
text: We used 2 NVIDIA A100 GPUs. We used CUDA 12.0, Pytorch 2.0.1, and huggingface 4.31.0.
For API models, we used instance version of gpt-4 for GPT-4, claude-instant-1.2 for Claude-1, hcx-002 for social value alignment and hcx-003 for common knowledge alignment for HyperCLOVA X, and PaLM 2 Text Bison for PaLM2.

heading: D.2 Experiment Prompts
text: For the experiments, we utilized prompt in Table 10. We used five distinct instructions, which are listed below.
• 아래의 질문에 대한 답변을 선택지에서 고 르세요. 답변은 1, 2, 3, 4, 5 숫자 형태로 합 니다. (Translated: Choose an answer from the following choices. Responses should be in numerical format: 1, 2, 3, 4, 5.)
• 질문에 대한 답변을 아래 선택지에서 1, 2, 3, 4, 5 형태로 합니다. (Translated: For the question, select an answer from choices below in the numerical format: 1, 2, 3, 4, 5.)

heading: D.3 Post-Processing Answers
text: The format of the language models’ generated responses vary, even if specific instructions on the answer format are given. Furthermore, since the answer options in the knowledge dataset are mostly phrases or sentences, the generated answers do not always match word by word with the answer choice they claim to choose. Thus we check if the first character is a valid option number either not followed by any character or followed by a delimiter, since the instructions given in the prompts specifically ask to only output the number of the option. If the response does not start with a number, GPT-4 (OpenAI et al., 2023) is employed as a judge to determine whether the generated answer carries the same semantic meaning as any of the provided choices, ensuring a more nuanced and accurate assessment. If GPT-4 cannot find any semantic similarity between the generated answer and all options (e.g., the generated answer contains multiple options), then the answer is considered either refrained or invalid as explained in Section 5.4. The number of refrained and invalid responses for each model are shown in Table 4.
One notable result is the high number of invalid responses for Gemini Pro, which is because the model responded with the letters "A", "B", "C", "D", presumably referring to options 1, 2, 3, and 4, respectively. Examples of refrained and invalid responses to social value questions include "답변은 개인의주관에따라다르므로, AI는답변을제공 할수없습니다. (Since the answer depends on the individual’s subjective opinion, AI cannot provide an answer.)" and "여기에 내용을 입력하십시오. (Enter your content here.)", respectively. Similarly, examples of refrained and invalid responses to common knowledge questions include "이질문에대한 답변을제공하고싶지않습니다. (I do not want to provide an answer to this question.)" and "선택지 번호를제시해주시기바랍니다. (Please indicate the option numbers.)", respectively.

heading: D.4 Additional Experiment Results on Social Value Alignment
text: Table 11 presents social value alignment across genders within each age group. As observed, the variance in alignment scores across both gender and age group is minimal. In most scenarios, PaLM-2 outperforms the others in SVA and A-SVA. HyperCLOVA X, on the other hand, consistently shows superior performance in N-SVA across all groups.

heading: D.5 Human Evaluation on Social Value Alignment
text: The instruction used for generation is ‘아래질문에 대한답변을 ’비동의’, ’중립’, ’동의’중에서고르 고그에대한이유도설명하시오. (Please choose from ’disagree’, ’neutral’, ’agree’ for the response to the following question, and provide an explanation for your choice.)’.
Figure 7 displays the survey interface in both the original Korean version and its English translation as presented to the participants.
Table 12 shows the statistics of the human evaluators by gender and age.
D.6 Samples which only HyperCLOVA X Correctly Answered
Table 13 presents two samples where only HyperCLOVA X provided correct answers.
In the first example, the four options are linguistically similar, as they all include ‘함 평 (Hampyeong)’ and ‘고구마 (sweet potatoes)’, along with semantically similar terms such as ‘사 건 (incident)’, ‘난동 (disturbance)’, ‘운동 (movement)’, ‘국가의 지원 (state support)’, and ‘농협 (Agricultural Cooperative Federation)’.
The second example requires familiarity with a specific Korean poem, ‘When the Day Comes’. The options contain academic terminology such as ‘미래지향적 (future-looking)’, ‘이상향 (utopia)’, ‘동경 (longing)’, ‘의지적 (determined)’, and ‘격정 적인 (passionate)’.
Based on these examples, we hypothesize that HyperCLOVA X excels in discerning between linguistically similar sentences and demonstrating an understanding of Korean specific knowledge.

heading: D.7 Additional Experiment Results on Common Knowledge Alignment
text: Table 14 shows common knowledge alignment for simple and complex samples, respectively. For simple common knowledge samples, the overall trend is similar to Table 3, with HyperCLOVA X being superior in all subjects except Mathematics and Science, where PaLM-2 outperforms the others. For complex common knowledge samples, the overall trend is slightly different, HyperCLOVA X being the best model is most subjects except for Mathematics and English and PaLM-2 being the best model in Mathematics and English. However, for both types of samples, HyperCLOVA X has achieved the highest score on total score.

heading: E Experiment Results on Small LMs

heading: E.1 Experiment Setting
text: With small LMs, we conduct experiments using likelihood-based approach. In this approach, a model is given a question accompanied by one of the candidate answers. We then compute the likelihood for each candidate, selecting the highest scoring one. We chose this method because small models tend to generate irrelevant responses. We also used five distinct yet semantically similar prompts as shown in Table 15 and Table 16. These five prompts have been carefully modified to maintain as much semantic similarity as possible. We tested four multilingual LMs and five Korean fine-tuned LMs. Korean fine-tuned models are developed upon open-sourced multilingual LMs, with additional fine-tuning on Korean cor-
pora. For multilingual LMs, we used Alpaca (Taori et al., 2023), Vicuna (Chiang et al., 2023), Polyglot (Ko et al., 2023), Llama-2 (13B) (Touvron et al., 2023). For Korean fine-tuned LMs, we used KoAlpaca7, KoVicuna8, KoAlpaca-Polyglot9, KULLMPolyglot (Lee et al., 2023c), KoLlama-2 (13B)10.

heading: E.2 Social Value Alignment
text: Table 17 demonstrates social value alignment in likelihood-based experiments. A notable finding is that in most cases Korean fine-tuned models tend to outperform multilingual models, with the highest scores achieved by KoLlama-2 and KoAlpacaPolyglot. This suggests that additional fine-tuning on Korean corpora enhances models understanding of Korean social values.

heading: E.3 Common Knowledge Alignment
text: Table 18 presents common knowledge alignment for each category, as well as the total score in likelihood-based experiments. Similar to social value alignment, Korean fine-tuned models outperform their multilingual counterparts. As 0.6 is our reference score, none of the models meet the baseline threshold.
