English(EN) When LLM-Based User Profiling Adds Value in Production Streaming Recommendation

LLM增强了探索型用户的流媒体推荐,但存在权衡 · 跟踪2个来源

两篇新研究论文探讨了在流媒体推荐系统中使用大型语言模型(LLM)进行用户画像的有效性。研究将LLM生成的画像与传统的聚合方法进行了比较,发现LLM对于行为偏离其历史记录的探索型用户更有效。然而,LLM生成的画像可能导致流行度吸引效应,降低目录覆盖率和新颖性。研究表明,上下文感知系统可以根据用户的消费模式动态选择画像策略。 AI

影响 基于LLM的用户画像可以提高某些用户群体的推荐质量,但需要仔细实施以避免负面影响。

    当LLM推断的用户上下文在生产流推荐中增加价值时

    Contextual information in recommender systems is shifting from static, predefined variables toward latent representations inferred from behavior. Large language models support this shift by rendering an unstructured interaction history as a natural-language summary, which yields …

    当基于LLM的用户画像在生产流式推荐中增加价值时

    Personalized recommendation depends critically on how user representations are constructed from historical behavior. Two paradigms have emerged for constructing semantic user profiles in content-based recommendation. First, aggregate methods derive user representations as numeric…
