## AI 摘要

PaperFlow提出三阶段框架：Profiling从异构冷启动证据构建维护结构化学术画像；Recommending在固定展示预算下通过多信号聚合排序每日论文流；Adapting根据语义不同的反馈信号更新用户状态并建模兴趣漂移。研究定义了纵向用户-天基准，包含24个模拟用户、50个每日论文流、1200个用户-天片段、20,727篇论文和497,448条记录，并设计了盲人评估协议。实验对比五种基线，PaperFlow在oracle排序、行为对齐和盲评分数上均最优。

Scientific paper recommendation is typically evaluated as static ranking over a fixed candidate set, yet real scientific reading unfolds as a daily, longitudinal process in which interests shift and feedback accumulates. We introduce PaperFlow, a framework that organizes it into three coupled stages: Profiling, which constructs and maintains a structured, inspectable scholarly profile from heterogeneous cold-start evidence; Recommending, which ranks each date-specific paper stream through multi-signal aggregation under a fixed display budget; and Adapting, which updates user state from semantically distinct feedback signals and models interest drift across days. We further define a longitudinal user-day benchmark that fixes users, dates, candidate pools, visible inputs, and hidden simulated relevance labels under a shared temporal information boundary. The benchmark contains 24 simulated research users, 50 daily paper streams, 1,200 user-day episodes, 20,727 unique papers, and 497,448 episode-paper records. We additionally specify a blind human-evaluation protocol to validate alignment between automatic metrics and expert judgments. Experiments against five scientific recommendation baselines show that PaperFlow achieves the strongest oracle-based ranking, the highest behavioral alignment with simulated reading selections, and the best blind human-evaluation score.
