Design and Function Construction of Cross-cultural Communication Platform: Exploring the Path to Promote Global Dialogue

In the context of deep integration of globalization and digitalization, cross-cultural communication has become a key driver for international understanding and cooperation. However, issues such as language barriers, cultural differences, and information asymmetry severely limit the effectiveness of cross-cultural communication. This study focuses on the "cultural silhouette" cross-cultural communication platform, exploring the implementation path of an intelligent cross-cultural communication platform through theoretical construction and practical innovation. The study first proposes a hybrid multi-source cultural data collection framework, integrating government open data, academic literature, social media, and other multimodal data to construct an ontology-based cultural knowledge graph, addressing the heterogeneity and fragmentation of cultural data in countries along the "Belt and Road." Secondly, it innovatively introduces microservices architecture theory, designing multilingual real-time translation algorithms and personalized recommendation systems to achieve modularization and dynamic optimization of platform functions. Furthermore, it proposes an intelligent service optimization theory driven by cultural sensitivity, enhancing the precision and inclusiveness of cross-cultural interactions through multi-level evaluation matrices and adaptive dialogue management models. Finally, it constructs a multidimensional evaluation system that integrates technical performance, functional integrity, user experience, and cultural dissemination effects, incorporating ethical risk prevention mechanisms to ensure the sustainable development of the platform. The theoretical contribution of this study lies in breaking through the limitations of traditional static cultural research, providing new technical approaches and methodological support for cross-cultural communication; its practical value is reflected in significantly lowering the barriers to cross-cultural exchange, offering intelligent tools for "Belt and Road" people-to-people connectivity. In the future, research can integrate emerging technologies such as the metaverse and generative AI to further deepen computational models of cultural intelligence and expand global application scenarios on platforms. This study not only provides a systematic theoretical framework for building cross-cultural communication platforms but also offers interdisciplinary paradigm references for humanities and social sciences research in the digital age.
