| 摘 要： | 为了更好地适应用户的个性化需求和普适计算环境的特征，提出一种基于上下文感知的普适服务框架。该框架包括服务呈现层、服务管理层、服务提供层和上下文感知层。通过基于社区的服务管理方式来屏蔽普适计算环境中服务的异构性、分布性，动态地感知与当前计算环境和用户活动相关的上下文信息，采用基于上下文的服务推荐机制为用户提供个性化的服务，从而更好地适应人的意图和环境 因素。

| Abstract: | In order to better adapt user’s personalized demand and the characteristic of ubiquitous computing environment, a ubiquitous service framework based on context-aware is put forward. The framework consists of four layers: service presentation layer, service management layer, service provisioning layer and context-aware layer. It uses the service management method based service community to shield the distribution and heterogeneous of services in ubiquitous computing environment. It is aware of context information which is related to current computing environment and user’s activity. It utilizes service recommender mechanism based on context so that it can provide personalized service for users. |
