• Abstract summary: Vision-language models' performance remains suboptimal on images from non-western cultures. Various benchmarks have been proposed to test models' cultural inclusivity, but they have limited coverage of cultures. We introduce the GlobalRG benchmark, comprising two challenging tasks: retrieval across universals and cultural visual grounding.

• Abstract: Despite recent advancements in vision-language models, their performance remains suboptimal on images from non-western cultures due to underrepresentation in training datasets. Various benchmarks have been proposed to test models' cultural inclusivity, but they have limited coverage of cultures and do not adequately assess cultural diversity across universal as well as culture-specific local concepts. To address these limitations, we introduce the GlobalRG benchmark, comprising two challenging tasks: retrieval across universals and cultural visual grounding. The former task entails retrieving culturally diverse images for universal concepts from 50 countries, while the latter aims at grounding culture-specific concepts within images from 15 countries. Our evaluation across a wide range of models reveals that the performance varies significantly across cultures -- underscoring the necessity for enhancing multicultural understanding in vision-language models.

  We introduce CROPE, a visual question answering benchmark designed to probe the knowledge of culture-specific concepts. Our evaluation of several state-of-the-art open Vision and Language models shows large performance disparities between culture-specific and common concepts. Experiments with contextual knowledge indicate that models struggle to effectively utilize multimodal information and bind culture-specific concepts to their depictions.

  LLMs are increasingly deployed in global applications, ensuring users from diverse backgrounds feel respected and understood. Cultural harm can arise when these models fail to align with specific cultural norms, resulting in misrepresentations or violations of cultural values. We present two key contributions: A cultural harm test dataset, created to assess model outputs across different cultural contexts through scenarios that expose potential cultural insensitivities, and a culturally aligned preference dataset, aimed at restoring cultural sensitivity through fine-tuning based on feedback from diverse annotators.

  We introduce a benchmark dataset for evaluating decoder-only large language models (LLMs) in understanding the cultural unity of concepts. CUNIT consists of 1,425 evaluation examples building upon 285 traditional cultural-specific concepts across 10 countries. We design a contrastive matching task to evaluate the LLMs' capability to identify highly associated cross-cultural concept pairs.

  We focus on extrinsic evaluation of cultural competence in two text generation tasks. We evaluate model outputs when an explicit cue of culture, specifically nationality, is perturbed in the prompts. We find weak correlations between text similarity of outputs for different countries and the cultural values of these countries.
