融合本地与全局偏好,提升地方新闻推荐精准度。
A Hybrid Recommendation Framework for Enhancing User Engagement in Local News
- 用本地+全局双模型融合,动态调整推荐权重。
- 在两个数据集上均超越单一模型,准确率和覆盖度双提升。
- 适合想提升用户留存的地方媒体使用。
地方新闻机构面临发行量下滑与全球媒体竞争的双重压力,亟需提升读者参与度。个性化新闻推荐系统可通过匹配用户兴趣提供解决方案,但传统方法多关注普遍偏好,忽略地方新闻中复杂的、多元的兴趣特征。本文提出一种混合推荐框架,整合本地与非本地偏好模型以增强用户参与度。基于局部模型价值的实证研究,该方法将区域特异性内容模型与更广泛兴趣模型统一于同一架构中。系统自适应融合专注于地区内容的本地模型与捕捉整体偏好的全局模型,通过集成策略与多阶段训练实现平衡。在两个数据集上进行评估:一个基于雪城报纸分布生成的合成数据集,以及丹麦数据集EB-NeRD(经大语言模型标注了本地与非本地内容)。结果表明,集成方法在准确率与覆盖率上均优于单模型基线,说明其能实现更优的个性化推荐,有助于提升用户参与度。研究对出版商具有实践意义,特别是地方媒体可借助社区特定与通用兴趣的结合,推送更相关的内容,从而提高用户留存与订阅率。本工作为推荐系统提供了新方向,通过桥接本地与全局模型,以可扩展的个性化体验重振地方新闻消费。
原文摘要 · Abstract (English)
Local news organizations face an urgent need to boost reader engagement amid declining circulation and competition from global media. Personalized news recommender systems offer a promising solution by tailoring content to user interests. Yet, conventional approaches often emphasize general preferences and may overlook nuanced or eclectic interests in local news. We propose a hybrid news recommender that integrates local and global preference models to improve engagement. Building on evidence of the value of localized models, our method unifies local and non-local predictors in one framework. The system adaptively combines recommendations from a local model, specialized in region-specific content, and a global model that captures broader preferences. Ensemble strategies and multiphase training balance the two. We evaluated the model on two datasets: a synthetic set based on Syracuse newspaper distributions and a Danish dataset (EB-NeRD) labeled for local and non-local content with an LLM. Results show our integrated approach outperforms single-model baselines in accuracy and coverage, suggesting improved personalization that can drive user engagement. The findings have practical implications for publishers, especially local outlets. By leveraging both community-specific and general user interests, the hybrid recommender can deliver more relevant content, increasing retention and subscriptions. In sum, this work introduces a new direction for recommender systems, bridging local and global models to revitalize local news consumption through scalable, personalized user experiences.
