###### Abstract

The widespread application of LLMs across various tasks and fields has necessitated the alignment of these models with human values and preferences. Given various approaches of human value alignment, there is an urgent need to understand the scope and nature of human values injected into these LLMs before their deployment and adoption. We propose UniVaR, a high-dimensional neural representation of symbolic human value distributions in LLMs, orthogonal to model architecture and training data. This is a continuous and scalable representation, self-supervised from the value-relevant output of 8 LLMs and evaluated on 15 open-source and commercial LLMs. Through UniVaR, we visualize and explore how LLMs prioritize different values in 25 languages and cultures, shedding light on complex interplay between human values and language modeling.

## 1 Introduction

The remarkable capabilities of LLMs have revolutionized general-purpose AI assistants leading to their widespread adoption in many tasks and fields [9, 46, 7]. Ensuring LLMs align with ethical and societal values has become as crucial as achieving high task performance [13, 24]. Numerous efforts have been made to impute AI systems with ethical principles and moral values, from designing robust frameworks for value alignment (e.g., RLHF, RLAIF etc.) [23, 25, 26, 27, 28, 29] to incorporate diverse perspectives into training data [23, 24, 25, 26]. These methods aim to make LLMs more performant, fairer, less toxic, and align better with human values.

Human values and preferences encompass a wide range, from universal ethical principles to culturally specific values, social etiquette, to industry and domain-specific preferences (SS2.1) and often become the foundation of AI regulations and guidelines. While LLMs are trained to incorporate these values, differences may emerge due to the crowd-sourced annotations and variations in RLHF efforts across different languages [1, 24, 25]. For example, whereas the majority of English language LLMs produced by North American institutions tend to manifest American coastal liberal values [11], and those from Chinese institutions might incorporate additional Chinese values [26, 25, 27, 28]. The values pre-trained in LLMs are not always clear, and it is uncertain if different models reflect consistent values within a language or culture.

To better understand the human values of LLMs, one can use surveys of human values to query

Figure 1: **UMAP Visualization of our UniVaR value embeddings**. Each dot represents a pair of a valie-eliciting question and the answer from a specific LLM in a certain language (15 LLMs and 25 languages in total). The distribution reflects distances and similarities between different cultures in terms of human values.



LLMs Durmus et al. (2023); Zhang et al. (2024); Brown et al. (2021); Zhang et al. (2023a). While the surveys are useful, they capture an incomplete picture of LLM value distributions, as they _only explore constrained subspace with a limited number of dimensions_. For instance, the cultural values Hofstede (2001); Hofstede et al. (2005) only uses 6 dimensions to represent a vast variability in human cultures, while the theory of basic values Schwartz (1999); Schwartz and Cieciuch (2022) and the World Value Survey (WVS) Inglehart et al. (2000); Inglehart (2006); Haerprfer et al. (2022b), each represented 19 and 10 dimensions of values, respectively. We argue that such a low-dimension semantic representation will likely fail to give a full picture of human values in LLMs. Instead, we aim a **high dimension representation of human value distribution** to reflect the complexity of the embedded values in LLMs. Ideally, this representation must be orthogonal to the linguistic patterns and the model architecture.

In this paper, we propose **Univ**orsal **Value R**epresentation (UnVivaR), the first high-dimensional representation of human values in LLMs. We formulate the value embedding learning problem and adopt a Siamese network Richter Weinberger and Saul (2009); Koch et al. (2015); Bertinetto et al. (2016); Reimers and Gurevych (2019, 2020) to enable the model to capture values while filtering out irrelevant information. To train UniVaR, we generate 21k value-eliciting questions based on 87 core human values and collect responses from 15 LLMs in 25 languages, resulting in a diverse dataset of 1M QA pairs. Previous works suggest that LLMs express distinct values across languages Lin et al. (2022); Durmus et al. (2023); AlKhamissi et al. (2024), we treat language variations as distinct value representations within each model.

We assess UniVaR by performing value identification tasks with \(k\)-NN and linear probing, and demonstrate that UniVaR embeddings effectively capture value-relevant features in LLMs. Through visualizing UniVaR, we further show how it captures cultural similarities and differences in values within LLMs (Figure 1). UniVaR offers systematic and statistical approach to understand value systems of LLMs. It facilitates explorations of how LLMs learn and prioritize values in different languages, and is ultimately a powerful tool for more transparent and accountable LLMs. We release UniVaR models and code.

## 2 Our approach: UniVaR

### Motivation

Human values and preferences can range from **(1)** high level ethical principles such as those under the "Universal Declaration of Human Rights" signed by 192 member states of the United Nations, to **(2)** more culturally specific values found in various moral philosophy schools such as the Enlightenment values in the West, Confucian values in East Asia, Hindu or Islamic values in many countries in the world; to **(3)** laws and regulations in various jurisdictions such as the lese-majeste law in Thailand or the GDPR in the EU; to **(4)** social etiquette and best practices in various human societies and professional settings; to **(5)** domain-specific human preferences such as "empathy" for health assistants and "helpful" for customer service agents, etc. These human values and preferences can originate from long philosophical traditions, and societal and professional consensus. They form the building blocks of all the AI regulations and guidelines published by different policy bodies today. This nature of human values motivates our proposed UniVaR - a high-dimension representation of human value distribution in LLMs. Figure 2 showcases the overview of UniVaR.

### Problem Formulation

We assume that some factors in LLMs contribute towards aligning with certain human values while others towards value-agnostic behaviors (e.g., wording, syntax, or style). Let an LLM parameterized by \(\theta\) be \(f_{\theta}\), our assumption can be formalized as \(\theta=\phi(\vartheta_{\mathrm{value}},\vartheta_{\mathrm{other}})\) with some function \(\phi\), where \(\vartheta_{\mathrm{value}}\) is the value-decisive factors and \(\vartheta_{\mathrm{other}}\) is the value-agnostic factors. Our goal is to extract \(\vartheta_{\mathrm{value}}\) such that we can analyze similarities of values from different LLMs or transfer values across LLMs.

If we know LLM parameters \(\theta\) and we are able to derive the inverse function \(\phi^{-1}\), we can directly recover value factors from by \([\vartheta_{\mathrm{value}},\vartheta_{\mathrm{other}}]=\phi^{-1}(\theta)\). However, this cannot be applied to closed-source LLMs where \(\theta\) is not accessible, and also there is no clue how to estimate \(\phi^{-1}\). The relationship and interactions between \(\vartheta_{\mathrm{value}}\) and \(\vartheta_{\mathrm{other}}\) are unknown, and locating value-decisive parameters from billions of LLM parameters is also difficult.

To overcome the difficulty of explicitly extracting \(\vartheta_{\mathrm{value}}\), we consider a surrogate task of learning a **value embedding**: a compact representation \(Z\) that contains maximized correlation with \(\vartheta_{\mathrm{value}}\) of 

LLMs while discarding other confounding factors as much as possible. Following the information bottleneck principle of representation learning (Saxe et al., 2018; Tishby and Zaslavsky, 2015; Tsai et al., 2021), the objective of value embedding learning can be written as:

\[\max_{Z}~{}\underbrace{I(\vartheta_{\mathrm{value}};Z)}_{\begin{subarray}{c} \text{maximizing}\\ \text{correlation}\end{subarray}}-\underbrace{H(Z)}_{\begin{subarray}{c} \text{minimizing}\\ \text{superfluity}\end{subarray}}, \tag{1}\]

where \(I\) and \(H\) denote mutual information and entropy, respectively.

### Value Eliciting Question Answering

The core challenge of value embedding learning lies in the fact that \(\vartheta_{\mathrm{value}}\) exists as a _latent_ variable (Kugelgen et al., 2021; Zimmermann et al., 2021). Thus, we utilize value eliciting question answering pairs, which are the observable input queries and output responses that are driven by \(\vartheta_{\mathrm{value}}\), to build value embedding.

Depending on input question \(Q\), LLM's \(\vartheta_{\mathrm{value}}\) may or may not be involved when generating the answers \(A\). For instance, questions about arithmetic operation would be dependent on reasoning capabilities represented by value-agnostic \(\vartheta_{\mathrm{other}}\), while \(\vartheta_{\mathrm{value}}\) hardly matters. Conversely, question involving an ethical dilemma such as the trolley problem should be highly dependent on \(\vartheta_{\mathrm{value}}\). Since our interest lies in values, we consider a set of **value eliciting questions**\(\mathcal{Q}_{\mathrm{value}}\) where the corresponding answers are dependent on \(\vartheta_{\mathrm{value}}\). Thanks to this dependency, if \(Q\!\in\!\mathcal{Q}_{\mathrm{value}}\), we know that one QA pair \(\langle Q,A\rangle\) gives \(I(\vartheta_{\mathrm{value}};\langle Q,A\rangle)>0\) for the first term in our objective (Eq. 1).

A single QA pair is not representative enough for \(\vartheta_{\mathrm{value}}\) since it is impossible to extrapolate the entirety of human values from a single QA. For instance, even a broad question such as _"What is the meaning of life?"_ or _"What is the ideal society?"_ can only elicit values that are related to terminal values (Rokeach, 1968, 1973) and cultural values (Hofstede, 2001; Hofstede et al., 2005), while neglecting other aspects of human values. Therefore, we consider using a wide array of valielecititing questions to elicit and represent LLM's values. We prepare a set of \(\lambda\) value eliciting questions \(\{Q_{j}\}_{j=1}^{\lambda}\), and get the corresponding answers from each LLM. We denote a set of QA pairs as \(X=\{\langle Q_{j},A_{j}\rangle\}_{j=1}^{\lambda}\).

### Multi-view Value Embedding Learning

With a large \(X\), there is sufficient guidance to maximize its dependency to \(\vartheta_{\mathrm{value}}\). However, this \(X\) might share value-irrelevant information such as wording and syntax, which makes the second term, _i.e._, minimizing superfluiy, not satisfied.

To eliminate these irrelevant information, we compress \(X\) by applying multi-view learning (Tsai et al., 2021; Shwartz and LeCun, 2024). Such strategy has already shown its effectiveness in learning compressed representation for various applications, such as for sentence semantics (Reimers and Gurevych, 2019), facial identity (Taigman et al., 2014), object category in images (Chen et al., 2020a), etc. As shown in Figure 2 (Right), we sample two views \(X_{1},X_{2}\) (two sets of value-eliciting questions and answers) that share the same values. We adopt a Siamese network with shared encoder \(g\) and takes two views as input producing repre

Figure 2: Overview of UniVaR. **Left**: our objective is to learn a value embedding \(Z\) that represents the value-relevant factor \(\vartheta_{\mathrm{value}}\) of an LLM. **Middle**: we elicit LLM values through QA, such that the \(\vartheta_{\mathrm{value}}\) is expressed by the distribution of its value eliciting QA set \(X\). **Right**: we apply multi-view learning to eliminate irrelevant information while preserving value-relevant aspects.

 

sentations \(Z_{X_{1}}=g(X_{1})\) and \(Z_{X_{2}}=g(X_{2})\). We then optimize \(g\) towards maximizing the mutual information across two views:

\[\max_{g}I(Z_{X_{1}};Z_{X_{2}}). \tag{2}\]

The principle of constructing views \(X_{1},X_{2}\) is to ensure that these QA pairs **share the same human value** while **not having other superfluous correlations**. If two views share \(\vartheta_{\mathrm{value}}\) (_i.e.,_ satisfying the multi-view assumption), maximizing mutual information between views will enforce \(g\) to capture the shared values information Shwartz and LeCun (2024). Conversely, \(g\) will compress \(X\) but retain some superfluous information \(I(X_{1};X_{2}|\vartheta_{\mathrm{value}})\) that is shared by \(X_{1},X_{2}\) but irrelevant to \(\vartheta_{\mathrm{value}}\) Tsai et al. (2021). Ensuring both requirements optimizes the objective in Eq. 1.

As LLM in each language has a distinct \(\vartheta_{\mathrm{value}}\)Lin et al. (2022); Durmus et al. (2023); Alkhamissi et al. (2024), we treat different language in an LLM as a different \(\vartheta_{\mathrm{value}}\) (_i.e.,_ LLM values of ChatGPT English and of ChatGPT Chinese are distinct). Using prompts in various languages leads to diverse responses Lin et al. (2022) and prompts in a culture's dominant language typically align more with that culture AlKhamissi et al. (2024)1. To ensure minimal sharing of linguistics aspect across views, we preprocess the \(X\) by translating all the value-eliciting QAs to English and paraphrasing the QAs to increase the diversity.

Footnote 1: It is important to note that using the dominant language does not guarantee an accurate representation of a culture Durmus et al. (2023); Alkhamissi et al. (2024). Moreover, current LLMs are found to be predominantly Anglocentric Naous et al. (2023); Havaldar et al. (2023).

## 3 Experiment Design & Implementation

### Training

Preparing Value-Eliciting QAFigure 3 outlines our value-eliciting QA pipeline. We start by compiling 87 reference human values from multiple human value studies including World Value Survey (WVS) Inglehart et al. (2000); Inglehart (2004); Hofstede (2005); Hofstede (2011), theory of basic human values Schwartz (1994); Schwartz (1999); (2004); Schmidt et al. (2007); Beierlein et al. (2012), the refined theory of values Schwartz and Ciceicuch (2022) and Rokeach Value Survey Rokeach (1968); (1973); (2008). We aimed to incorporate values from diverse, well-cited sources that offer distinct perspectives, resulting in a broad set that reflects the wide range of human values, as discussed in SS2.1.2 For each reference value (_e.g.,_ Individualism vs Collectivism), we use LLMs to generate 50 relevant value-eliciting questions \(Q\in\mathcal{Q}_{\mathrm{value}}\) (see SSD.2 for examples). After manually verifying and filtering our irrelevant questions, we retain 4,296 questions. To enhance robustness, we paraphrase each question 4 times, resulting in a total data size of 21,480 (4,296 \(\times\) 5) questions. These questions are then translated into 25 languages to better understand the values expressed by LLMs across different languages. The details of prompts for constructing value-eliciting questions are in Appendix D.1.

Footnote 2: Note that this set is not intended to be exhaustive or represent an ideal list, but rather an inclusive attempt to capture a comprehensive spectrum of values.

To obtain the corresponding answers, the valie-eliciting questions in different languages are fed into LLMs. To minimize linguistic varia 

tions across different languages, all non-English question-answer pairs are then machine-translated into English. This translation step eliminates language information from becoming a confounding factor when training UniVaR since it is irrelevant to human values. Overall, we collected \(\sim\)1M QA pairs for training. For translation, we employ the widely used NLLB-200 (3.3B) Team et al. (2022).

Model and Language CoverageWe incorporate 15 off-the-shelf chat or instruction-following LLMs Sanh et al. (2022); Muennighoff et al. (2022); Wei et al. (2022); Longpre et al. (2023) to ensure their ability to answer the given query. We prioritize LLMs that have undergone human value and preference tuning such as safety tuning Zhang et al. (2023b); Meade et al. (2023); Bianchi et al. (2024), RLHF Christiano et al. (2017); Ouyang et al. (2022), or DPO Rafailov et al. (2024). Out of 15 LLMs, we incorporate QAs from 8 LLMs for training and leave the other 7 as unseen LLMs for validation and evaluation. We support 25 languages which are considered high-resource languages within LLMs under study. In total, we have 127 distinct LLM-language pairs. The list of LLMs and languages is shown in Appendix SSC.

Loss Function and Training DetailsWe use the pre-trained Nomic Embedding Nussbaum et al. (2024) v1 as our backbone model to allow capturing long-context information. We adopt the InfoNCE loss function van den Oord et al. (2019) to maximize the objective function Eq. 2 in SS2, but other alternatives can also be used Zbontar et al. (2021); Grill et al. (2020); He et al. (2020); Chen et al. (2020a, b); Gao et al. (2021). The InfoNCE loss function encourages the embeddings to be similar for views from same value ID and dissimilar for views from different value ID. Given a batch of \(B\) view pairs, the InfoNCE loss is defined as:

\[{\mathcal{L}_{\text{InfoNCE}}=-\frac{1}{B}\sum_{i=1}^{B}\log\frac{\exp(\sin(Z_ {X_{1}}^{(i)},Z_{X_{2}}^{(i)}/\tau)}{\sum_{j=1}^{B}\exp(\sin(Z_{X_{1}}^{(i)},Z _{X_{2}}^{(j)})/\tau)},} \tag{3}\]

where \(\operatorname*{sim}(\cdot,\cdot)\) is a similarity function, \(\tau\) is a temperature, and \(B\) is the batch size. The InfoNCE loss encourages similar embeddings for the same value ID, _i.e., \(\operatorname*{sim}(Z_{X_{1}}^{(i)},Z_{X_{2}}^{(i)})\)_, while applying uniformity regularization in the denominator part. Minimizing \({\mathcal{L}_{\text{InfoNCE}}}\) maximizes a lower bound on the mutual information, _i.e., \(I(Z_{X_{1}};Z_{X_{2}})\geq\log(B)-{\mathcal{L}_{\text{InfoNCE}}}\)_. The detailed training hyperparameter is described in Appendix B.1.

### Evaluation

TaskTo quantitatively evaluate whether representation effectively captures value-relevant features in LLMs, we introduce an **LLM value identification task**. This task measures the accuracy of classifying a given QA pair to the value ID. Recognizing that LLMs exhibit distinct values across languages, value ID refers to LLM-language pairs, _e.g.,_ GPT-4 English and GPT-4 Chinese are considered to be distinct, while QA pairs come from GPT-4 English share the same value Lin et al. (2022); Durmus et al. (2023); AlKhamissi et al. (2024). To mea

sure the identification accuracy, we follow standard practice of _k-Nearest-Neighbour_ (kNN) classification and linear probing with frozen features.

DataFor a fair evaluation, we incorporate off-the-shelves questions that are not directly derived from the value sources in the training phase. We construct an evaluation dataset based on 4 sources: 3 well-established value questionnaires in social science and psychology (_i.e.,_ PVQ-RR Schwartz2017; Schwartz2022), WVS (Inglehart2000), Inglehart2004), and GLOBE survey House et al.2004; Javidan and Dastmalchian2009)) and ValuePrism Sorensen2024), a large-scale value dataset for endowing AI with pluralistic human values, rights, and duties.3

Footnote 3: Note that these datasets are not used in training.

These data sources do not originally provide natural questions for LLMs, hence we employ Mixtral 8x7B Jiang et al. (2024) to generate value-eliciting questions based on the context provided in the data sources (See SSB.2 for details). We then translate the questions into 25 languages as detailed in Appendix C. Using the multilingual questions, we generate the answers using all LLMs under study on the languages that are supported by each of the LLMs, and then translated the QA back to English. The resulting English-only value-eliciting QAs data is used for evaluating the effectiveness of UniVaR.

BaselinesThe existing embedding focuses on semantic embeddings which may not capture human value space at all or combined with other features. We want to highlight existing semantic embedding has limitations for capturing human values. We compare UniVaR to word embedding model, i.e., GloVe Pennington et al. (2014a) and various sentence embedding models, i.e., RoBERTa Liu et al. (2019), XLM-R Conneau et al. (2020), MPNet Song et al. (2020), Nomic Embed v1 Nussbaum et al. (2024), and LaBSE Feng et al. (2022).

## 4 Results and Analysis

### Evaluation Results

UnivaR representations capture value-relevant featuresWe present the results of the aggregated balanced average accuracy for the LLM value identification task across 4 corpora (Table 1). UniVaR showcases a strong capability surpassing all baselines by \({\sim}15\%\)_k_-NN accuracy and \({\sim}10\text{--}15\%\) linear probing accuracy@10 on the LLM value identification task. Word embedding and sentence embedding representations perform poorly with \(<\)5% _k_-NN accuracy score on the LLM value identification task indicating that there are significant differences between value representations from UniVaR and existing word/sentence embedding representations. Further elaboration on the performance breakdowns in Appendix E.

UnivaR representations minimally capture non-value-relevant factorsDespite the efforts to eliminate the influence of non-value-related confounders through English-only multi-view learning, UniVaR might still be affected by generation and translation artifacts such as writing style, choice of common words, and translationese Firmage (1986); Gellerstam (1986); Iliesei et al. (2010); Aharoni et al. (2014). We investigate such artifacts by checking whether source LLMs can be distinguished using our UniVaR representations on non-value-eliciting QAs, e.g., "Can you implement KMP Algorithm with python?" gathered from LIMA Zhou

Figure 4: Performance comparison of UniVaR between value-eliciting QAs and non-value-eliciting QAs from LIMA Zhou et al. (2023). The influence of non-value-related confounders in UniVaR is minimal compared to baselines signifies by the substantial performance gap between the two tasks.

 

et al., 2023). Ideally, a value-embedding should not be able to identify LLMs when **non-value-eliciting questions** are used because these questions would not elicit "human values" embedded in LLMs in the answer. The substantial performance decline between value-eliciting and non-value-eliciting QAs, as illustrated in Figure 4, provides clear evidence of this characteristic within UniVaR. Furthermore, UniVaR captures the least translationese factors compared to other representations (see Appendix F). These underscore the effectiveness and superiority of UniVaR as a robust and reliable value embedding model.

Impact of view size in UniVaRWe further assess the effect of view size in the multi-view learning of UniVaR by incorporating more QAs in the input. We train a model using varying degrees of the number of QA per view \(\lambda\in\{1,5,20,80\}\). In Table 1, we demonstrate that learning the dynamic number of QAs \(\lambda\) brings some benefits in the case of generalization when using only a single QA (\(\lambda=1\)). Nonetheless, the improvement peaked at \(\lambda=5\), while it consistently decreases when using higher \(\lambda\) potentially due to underfitting on the \(\lambda{=}1\) case due to the huge dynamic range of the number of QA. In later sections, we use the best model with \(\lambda{=}5\) as our default model unless otherwise specified.

### Map of UniVaR Representations

Inspired by human value maps such as Hofstede's Globe (Hofstede, 2001; Hofstede et al., 2005; Hofstede, 2011; Hofstede Minkov, 2013) and World Cultural Map (Inglehart et al., 2000; Inglehart, 2004, 2006) , we introduce a value map of LLMs to visualize the human values embedded in LLMs. To create the value map independent from the training data, we utilized the QAs from four value-eliciting question sources described in SS 3.2. We encode each QA using UniVaR and we visualize the map of LLM values by projecting the value embeddings into a 2D plane using UMAP (McInnes and Healy, 2018). The result of the value distributions are shown as a "world map" in Figure 1. In general, we observe that value QA pairs in the same language from different LLMs are clustered together, which show that the values embedded in LLMs largely come from the culture of the language they are trained in. In this case, language acts as a proxy for culture (AlKhamissi et al., 2024).

Relation between LLM values and human culturesThere is also a separation of value distribution between LLMs in different languages as shown in Figure 5. The distance of values across different languages also signifies the similarities and differences of human values between different cultures. For instance, "Chinese-Japanese-Korean", "German-French-Spanish", and "Indonesian-Arabic-Malaysian" are closer in value distribution compared to the other language pairs with a relatively distant culture. German, French, and Spanish share similar European values. Chinese, Japanese, and Korean share similar Confucian and Buddhist values. Indonesian, Malaysian, and Arabic cultures share Islamic values, despite the linguistic difference between Indonesia/Malay and Arabic. Interestingly, English value distribution is relatively far from that of French, German, Italian, and Spanish, despite originating from

Figure 5: **(left) Grouped map of UniVaR value representation. (right) 2023 version of Inglehart–Welzel Cultural Map4. The UniVaR value representations demonstrates relations between LLM values and human cultures where similar cultures tend to be clustered together within the same region, while unrelated cultures tend to be disjoint and located far apart from one to another forming regional values.**



countries with Western values. This agrees with the human value map in WVS (Inglehart et al., 2000; Inglehart, 2004, 2006) (see Figure 5 (right)), where English-speaking societies are categorized into their own group due to the impact of colonization and massive immigration from the colonial society (Crystal, 2003; Tardy, 2004; Smokotin et al., 2014; Suzina, 2020). As shown in Figure 7, this pattern is also consistent across four different value corpora indicating that the value representation in UniVaR is robust to the variability of questions. While the values across LLMs in each language are generally closer from one to another, LLMs that are trained from a huge amount of translated data (e.g., Aya and JAIS) tend to demonstrate similar values across languages. This is shown by the UniVaR representations across different languages of the models Aya and JAIS.

Understanding UniVaR from human value perspectivesTo further understand the relation between UniVaR representations and human values, we conducted a qualitative analysis to explore how the distance in embedding space manifests conceptually. We analyzed model responses to valueliciting questions, noting that greater distances in UniVaR embedding often correspond to contrasting values, while closer distances indicate shared values. For example (Figure 6), ChatGPT-English and ChatGPT-Chinese, which are further apart, show distinct values: ChatGPT-English emphasizes liberty of choice for vaccination, whereas ChatGPT-Chinese highlights social responsibility. Conversely, ChatGPT-French and Mistral-German, which are closer, share the value of the rule of law in responses about tracking a criminal's IP address. More details are shown in Appendix H.

## 5 Conclusion

The adoption of LLMs across various fields necessitates understanding how these models represent human values. Our paper introduces UniVaR, a high-dimensional, language- and model-invariant representation, that enables better understanding of the human value aspect in LLMs. UniVaR allows us to examine how different LLMs prioritize values across languages and cultures, shedding light on the complex interplay between human values and AI systems. Our approach enables us to statistically analyze the value systems embedded in LLMs, providing transparency and accountability in developing and using AI technologies. This approach helps align LLMs with human preferences, providing insights into the value systems embedded in these AI technologies.

Figure 6: The diagram shows how UniVAR embedding distances correlate with those of human values. On the left, ChatGPT-French and Mistral-German, which are closer, share the same value. On the right, ChatGPT-English and ChatGPT-Chinese, which are further apart, reflect contrasting values.

Figure 7: Per dataset visualization of UniVaR representations. UniVaR representations show robust human value representations across value corpora.

 



### Limitations

Coverage of ValuesWe used a combination of existing value taxonomies as a starting point for the value-eliciting QAs resulting in 87 core values from five different sources that we found particularly well cited and distinct from one to the others. Human value taxonomy is not a fixed entity and some philosophers think that we can never have a comprehensive human value taxonomy. The research on human values in philosophy, social science, and psychology is ongoing; and there are more crowdsourcing efforts for collective value datasets. Our approach is agnostic to taxonomy development and can be updated with future taxonomies of human values and preferences.

Coverage of LLMsOur work underscores the significant finding that values encoded in LLMs vary across languages, reflecting the similarities and differences in human values between diverse cultures. While our study provides valuable insights, it only studied 15 LLMs, with 7 unseen LLMs in 25 languages across 4 value-eliciting question sources. Our current result does not cover the full diversity of LLMs, languages, or taxonomy sources. We will release the tool and invite the makers of LLMs to extend the coverage to build a more comprehensive and holistic value coverage across more LLMs, languages, and taxonomies in future work.

## Ethics Statement

This paper proposes UniVaR as a tool for inspecting the value distributions in LLMs to compare different models, languages, and cultures. It uses existing value taxonomy in doing so. It is not a benchmark on the adequacy of human value alignment in each LLM.

Related Work

Value Alignment in LLMsLLMs are aligned to human values for enhanced service and reduced risks (Liu et al., 2023) with three major goals (Yao et al., 2023): teaching LLMs to follow human instructions (Ouyang et al., 2022), aligning LLMs to implicit human preferences (Christiano et al., 2017), and conforming LLMs to pre-defined principles (Bai et al., 2022b). Value alignment typically involves Supervised fine-tuning (SFT) and RLHF/RLAIF. In SFT, models are fine-tuned using well-curated conversation data data (Kopf et al., 2024; Chen et al., 2023; Nakano et al., 2021; Shen et al., 2023) following human desirable features (Yao et al., 2023; Scheurer et al., 2023; Kopf et al., 2024; Glaese et al., 2022; Ganguli et al., 2022) through various training paradigms such as contrastive learning (Adolphs et al., 2023; Khalatbari et al., 2023) and distillation (Hong et al., 2023). RLHF, commonly used by recent LLMs (Touvron et al., 2023; Achiam et al., 2023; AI@Meta, 2024), adjusts models' policies through RL by receiving feedback from a reward model aligned with human preferences as in Proximal Policy Optimization (PPO) (Schulman et al., 2017). Unlike PPO , Direct Preference Optimization (DPO) (Rafailov et al., 2024), eliminates reliance on a reward model. Similarly, RLAIF (Lee et al., 2023; Yuan et al., 2024; Honovich et al., 2023; Liu et al., 2023a) generates feedback from the model itself to avoid costly human annotations. While RLHF implicitly elicits preferences from ranking data, Constitutional AI (Bai et al., 2022b) establishes principles for AI to enhance model alignment to explicitly-defined human values through self-critique and response modification.

Surveying Human Values in LLMsEarly studies on understanding human values in language models, such as the ETHICS dataset (Hendrycks et al., 2020), cover various ethical frameworks including justice, deontology, virtue ethics, and utilitarianism. Zhang et al. (2023) further analyzed how language models categorize and reason about different values. Related research includes examining alignment with diverse societal views and stances, referencing global opinion surveys like the Pew Global Attitudes (PEW) and World Values Surveys (WVS) (Inglehart et al., 2000; Inglehart, 2006; Haerpfer et al., 2022a). Studies such as Durmus et al. (2023) and AlKhannissi et al. (2024) specifically focus on cultural and social value alignment in language models, using data from these surveys. Zhang et al. (2024) employ social value orientation (SVO) measures to assess the alignment of language models with human values. Our work aims to develop methods for capturing complex human values in high-dimensional spaces to enhance understanding and verification of language models' alignment with human values.

High-Dimension Embedding RepresentationDistributed representations of entities (Hinton, 1984) underpinned the advancement of embedding representation, enabling algorithms to capture nuanced semantic relationships and enhance generalization capabilities. Seminal works in NLP laid the groundwork for word embeddings (Hinton et al., 1986; Rumelhart et al., 1986; Elman, 1990; Mikolov et al., 2013). This progress was further accelerated by Mikolov et al. (2013); Pennington et al. (2014), who refined methods to generate word vectors, subsequently enriching research on sub-word and sentence-level embeddings (Britz et al., 2017; Kudo and Richardson, 2018; Reimers and Gurevych, 2019). In parallel, computer vision benefited from embedding techniques to capture object representations (Gui et al., 2016; Mettes and Snoek, 2017; He et al., 2017), with recent expansions into sub-object representations (Chen et al., 2024) demonstrating the versatility of this approach. Embedding has also been applied in healthcare and recommendation systems to model complex behaviors (Choi et al., 2016; Covington et al., 2016; Cahyawijaya et al., 2022). Our work extends the embedding paradigm to abstract value representations elicited by LLMs, advancing the applicability of embedding representations in understanding LLM preferences.

## Appendix B Training and Evaluation Details

### Training Details

To train the model, we adopt a similar hyperparameter setting used for fine-tuning a pre-trained BERT (Devlin et al., 2019) and RoBERTa (Liu et al., 2019) models. The model was trained using AdamW optimizer (Loshchilov and Hutter, 2019) for 1 epoch with a learning rate of 1e-5 and a linear warmup scheduler with a warmup step of 1000. During training, we use a batch size of 64 for both training and 

validation. For the view size of our multi-view value embedding learning, we explored the dynamic number of QA per view from \([1..\lambda]\). We explore varying degrees of \(\lambda\in\{1,5,10,80\}\). All our experiments are conducted on 4 NVIDIA Tesla A800 GPUs.

### Evaluation Details

Since the original datasets do not have value-eliciting questions, we adopt the value related context that are given in the existing datasets. For PVQ-RR and ValuePrism, we use the situations provided. For GLOBE survey, we create the context from the sentence and two opposing values within each question. For WVS, we take the question as is when the item is already formatted as a question, or we take the situation or multiple choices provided if it is not a question.

For linear probing, we train a linear classifier using AdamW optimization with a learning rate of 2e-3 and a batch size of 512. We train the classifier for 20 epochs. For the kNN experiment, we use a number of neighbours \(k=50\). We measure the accuracy and F1-score between the predictions and labels for kNN, and accuracy@1, accuracy@5, and accuracy@10 for linear probing.

## Appendix C LLMs and Languages Coverage

Our work covers a total of 15 LLMs and 25 languages spread across various language families and cultural values. We utilize 8 LLMs as the sources of training data in our UniVaR training, while 7 others are incorporated as unseen LLMs for evaluation and visualization of the value map. The complete list of all LLMs and languages used within this work is described in Table A1. The detailed supported language list is presented in Table A2 along with the NLLB 3.3B and NLLB 54B MoE performance gathered from Team et al. (2022) as references for the translation quality.

 



## Appendix D Value Eliciting Questions (Methodology)

### Generation Steps

**Step 1:** For the training data, we first generate scenarios from the collected 87 human values, we generate the situation with GPT4 using the following prompts:

Create 50 scenarios highlighting the personal and regional variations in terms of 'VALUE' in responses without specifying any region or country in the question. Formulate each scenario as a short and concise question. Aim for clarity and facilitate data augmentation. Make the examples natural and imagine the data is from online users. return the scenario questions in a numbered list format.

**Step 2:** For generating the questions, we turn the situation into a question with Mixtral 8x7B using the following prompt template:

Given appremise about "{SITUATION}", write question asking whether the speaker should do or not do the aforementioned premise.'

**Step 3:** From there, we will have a list of questions and then we paraphrase the questions 4x to ensure we capture the most consistent representation of the question is not by chance. We use Mixtral 8x7B for paraphrasing with the following chat template

Write 4 different paraphrased questions separated by a newline from the following question: "(QUESTION)"

**Step 4:** We then translate each question into multiple languages using NLLB 3.3B to all the languages listed in Appendix C.

**Step 5:** For each question, we then prompt each LLMs on the language supported by the LLMs as defined in Appendix C. We prompt each LLM using the generated question as the input with the exact format suggested in each of the corresponding model cards.

### Samples of Generated QAs

We provide the examples of the generated value-eliciting questions from different reference values generated by the Mixtral-8x7B-Instruct-v0.1 Jiang et al. (2024) model in Table A3.

## Appendix E Comprehensiveness of Adopted Values In UniVaR Training and Evaluation

Ensuring comprehensive adopted values is crucial to avoid intended bias in the choice of value dimension (e.g., overemphasis or ignorance of certain aspects). To do so, during the training, we incorporate 87 core values from 5 different sources - i.e., Rokeach Value Survey, World Value Survey, Schwartz Value Survey, Value Survey Module, and AllSides Media Bias - that are based on human value studies cited in SS3.1 for constructing value eliciting QAs. To evaluate the performance fairly, we incorporate questions from existing sources (i.e., ValuePrism, PVQ-RR, GLOBE, and World Value Survey) that are not directly derived from the value sources in the training phase.

Among the 4 value corpora, PVQ-RR and World Value Survey have the most overlap in terms of values with the training data, while the GLOBE and ValuePrism are fairly distinct with the values in the training data. In this case, the reported aggregated result of balanced average accuracy across 4 corpora in Table 1, might reflect some bias in the choice of value dimensions. Nonetheless, we further show that there is a consistent trend of performance across different models between each of the 4 value corpora as shown in the detailed comparison in Table A4. This breakdown of results suggests that UniVaR has a minimal bias between different values and it also generalizes well to unseen QAs and values.

## Appendix F Translationese Evaluation

Experiment SettingFor evaluating translationes, we utilize the parallel data from the European Parliament (EuroParl) Koehn (2005). Unlike prior works Amponsah-Kaakyire et al. (2021); Pylypenko et al. (2021), we use a more recent version of EuroParl data, i.e, EuroParl-ST Iranzo-Sanchez et al. ( 

2020), dated from 2008-2012. Similar to our experiment setting, we only take the original and translated English sentences and use the representation of the models to predict the source language of the sentence using kNN and linear probing. To alleviate the format gap of the nature QA input of UniVaR, we explore two variants of inputs, i.e., text-only and paraphrase input formats. text-only format uses only the English translation as the input, while the paraphrase format forms the input representation much more similar to how UniVaR is trained, by translating the original non-English sentence into English, and use it to make a QA for paraphrasing, i.e., "What is the paraphrase of <MACHINE-TRANSLATED-TEXT>?NA: <ENGLISH-TRANSLATION>".

ResultsWe showcase the result for the text and paraphrase formats in Table A5. UniVaR under performs all other baselines on the text-only format, showcasing its inferior performance on capturing translationese in single sentence texts. While on the paraphrase format, despite having a much similar format with how UniVaR is trained on, all UniVAR variants still produce the lowest scores compared to most baselines. These empirical results indicate that UniVaR captures much less translationese features compared other representations 



## Appendix G Interpreting Value Alignment with UniVaR

OverviewIn this section, we showcase a UniVaR utilization to qualitatively assess the degree of value alignment in LLMs by visualizing LLM's value representation in UniVaR embeddings. We implement an experiment employing Direct Preference Optimization (DPO) Rafailov et al. [2024] to adapt the value representation of Phi-2 model 20, which is trained on English datasets and consequently exhibits values similar to those shown by models prompted in English (eng in Fig. A1). We experiment to align Phi-2 model towards Chinese value (i.e., LLM values that are elicited in Chinese; zho in Fig. A1). We construct a preference-tuning dataset from model-generated QA pairs based on the ValuePrism dataset using ChatGLM 6B and SealLM 7B models. To steer from Chinese language values to English, we take responses in Chinese as preferred answers while rejecting responses in English.

Footnote 20: [https://neurips.cc/media/neurips-2023/Slides/83968_5Gxuv%z.pdf](https://neurips.cc/media/neurips-2023/Slides/83968_5Gxuv%z.pdf)

Experiment SettingWe explore a preference alignment framework using DPO Rafailov et al. [2024] for value transfer, directly training LLM without relying on a reward model. We employ DPO to train Phi-2 with \(\beta=0.01\) and a learning rate of \(1e-7\) on a preference-tuning dataset derived from model-generated QA data based on ValuePrism questions and ChatGLM 6B and SeaLLM 7B responses, partitioned with an 80-20 train-test split. Table A6 displays the answer generation samples from PVQRR and ValuePrism questions of the original Phi-2 outputs alongside those that undergoes DPO training for 1000, 2000, and 3000 steps.

The generated answers demonstrate a shift from values common in English LLM responses towards the Chinese counterpart. In the first row, initially the models highlight values of individualism. Over the DPO training steps, they pivot towards emphasizing benevolence, underlining the importance of social responsibility and helpfulness in familial and social contexts. Furthermore, in the last row, the transition from valuing affective autonomy towards prioritizing harmony and interpersonal conformity is evident. These transitions, along with the visual and quantitative measurement depicted in Figure A1, illustrate the trajectory of DPO training process in aligning the model's output towards different cultural values.

ResultWe illustrate the effectiveness of UniVaR to measure and visualize the degree of alignment through the visualization in Figure A1. From left to right, we can observe the shift of English value representation of Phi-2 from its original value region (eng) towards the target values (zho). To further quantify this shift, we compute the Euclidean distance between the centroids of value representations of Phi-2 model and those of target and reference. The distances indicate the degree of value similarity between the sets of embeddings, thereby enhancing the transparency of the value alignment process.

In the first row the emphasis of individualism are shifted towards benevolence. In the last row, the focus on valuing affective autonomy is adapted towards prioritizing harmony and interpersonal conformity.



Qualitative Analysis of UniVar

To give better insight into UniVar value space, we conduct a sample-level analysis to understand the effect of closeness in the value representation space across different LLMs. Table A7 represents case studies where distant LLMs exhibit different or contrasting values while Table A8 presents cases where closely located LLMs in the UniVar value space manifest the same values.

There should be mutual respect and care between friends. If you feel that your friend has hurt your feelings unintentionally, then you can choose to temporarily distance her to protect your feelings.

Open communication is the key to maintaining a healthy friendship. Try to talk to your friend about how you feel about his or her actions without blaming or making things worse. Talk honestly and openly so that you can reach a mutual understanding. In that way, you may be able to resolve problems well and strengthen the hub. \\ \cline{2-3}  & Value & Emotional security V.S Benevolence \\ \hline \hline \end{tabular}

One option could be to try and find a way to transport the children to safety without putting them in harm's way. This could involve setting up a safe zone or finding alternative shelter for them. Another possibility could be to try and negotiate with the individuals or groups posing a threat to the children. This might involve talking to them, finding common ground
