摘　　要：在科研信息服务背景下,探究如何从海量业务数据中对用户活跃度进行准确测算与分析,为实时评价活动效果、调整用户政策,提供基于数据计算和科学分析的决策依据。以国家科技图书文献中心(NSTL)为例开展实证分析,采用衰减算法计算用户行为量,通过熵权法细分每个行为的贡献量,对一段时间内NSTL不同类型用户活跃度进行测试与分析,提出适用于科研信息服务平台的应用场景,实现用户活跃度算法工程化应用。Under the background of scientific research service platform,this paper explores how to accurately measure and analyze user activity from massive business data,so as to provide decision-making basis based on data calculation and scientific analysis for real-time evaluation of activity effect and adjustment of user policy.We take the National Science and Technology Library(NSTL)as an example to carry out empirical analysis.The attenuation window is used to calculate the amount of user behavior,and then the entropy weight method is used to subdivide the contribution of each behavior.The activity of different types of users in NSTL is tested and analyzed over a period of time,and the application scenario applicable to the scientific research service platform is proposed to realize the engineering application of user activity algorithm.
