Shaanxi hotspots in foreign media coverage: An LDA-based study from the perspective of international communication and regional development
国际传播与区域发展视角下的陕西外媒报道热点研究——基于LDA模型

摘要

随着中华文化“走出去”战略的不断推进，区域文化的对外传播已成为国家形象构建与国际文化话语权竞争的重要组成部分。本研究基于潜在狄利克雷分配（Latent Dirichlet Allocation, LDA）主题模型，对近年来境外媒体关于“陕西”的英文新闻报道语料进行数据挖掘与热点分析，考察境外媒体对陕西新闻热点话题的内容分布、演变逻辑及发展趋势。借鉴舆情研究中新闻与公众评论的主题关联建模思路，本研究进一步探讨境外新闻话语中传播内容与区域经济发展之间的关系，从而揭示国际传播中区域形象构建与媒体关注热点的异同。本研究将LDA主题建模与新闻数据挖掘方法应用于陕西新闻热点分析，有助于提升新闻话语分析的科学性与前瞻性，并为陕西乃至西部地区优化国际传播路径与热点形象构建提供实证支持与策略参考。

Abstract

With the continuous advancement of China’s “Going Global” strategy, the international dissemination of regional culture has become a key component in shaping national image and competing for cultural discourse power. This study employs the Latent Dirichlet Allocation (LDA) topic model to conduct data mining and hotspot analysis on English news reports about Shaanxi published by overseas media in recent years. It examines the content distribution, evolutionary patterns, and development trends of news hotspots concerning Shaanxi. Drawing on approaches from public opinion research that associate news with audience commentary, the study further explores the relationship between the dissemination of overseas news discourse and regional economic development, thereby revealing the similarities and differences in regional image construction and media attention in international communication. By applying LDA topic modeling and news data mining to the analysis of Shaanxi-related news hotspots, this study contributes to enhancing the scientific rigor and foresight of news discourse analysis and provides empirical support and strategic insights for optimizing international communication strategies and hotspot image construction in Shaanxi and the broader western region of China.
