摘　　要：个性化信息服务是能够满足用户的个体信息需求的一种服务 .它通过对用户个体及使用习惯的分析而主动的向用户提供其可能需要的信息服务 .本文介绍了一个个性化系统的设计和实现 .该系统有以下几个特点 (1)通过对用户行为轨迹的统计数据进行分析实现了用户兴趣焦点的动态演变 .(2 )系统通过在用户兴趣衰减模型中引入了菲波拉契数列有效的提高了用户兴趣衰减的灵敏度 .(3)系统通过对相似用户的兴趣分析实现了预测用户的潜在兴趣焦点的功能 .Personalization service is a kind of service which can satisfy individual customer's need for information. It provides customers with information, which is possibly needed, by analyzing the trace of their actions. This paper takes the initiative to introduce the design and realization of such personalization system. This system has three characteristics: (1) it can realize the dynamic evolvement of user's interest focus by tracing their behaviors; (2) it can considerably improve the sensibility of the user-interest-attenuation by introducing the Fibonacci Array into the Attenuation model; (3) it can forecast user's potential interest focus by analyzing the interests of users who have similar behaviors.
