摘　　要：数字资源服务已从传统Web环境进入到异构环境(包括终端软硬件环境和网络环境的异构),目前异构环境读者上下文模型研究的成果极为稀少,尚无法满足精准数字资源个性化服务的需求。论文从异构环境视角,研究全面、精准的读者上下文模型构建方法。以异构环境读者上下文为研究对象,从读者上下文模型架构、异构环境读者上下文定义、基于本体的读者上下文建模、异构环境读者上下文获取、读者上下文模型更新五方面,探索构建异构环境读者上下文模型的方法。论文提出的异构环境读者上下文模型在深度和广度上有了较大提升,为数字资源的个性化精准服务提供保障。Digital resource service has changed from traditional web environment to heterogeneous environment(including the heterogeneity of terminal software and hardware environment and network environment).At present,the research results of reader context model in heterogeneous environment are extremely rare,which can not meet the needs of personalized services of accurate digital resources.This paper studies the construction method of comprehensive and accurate reader context model from the perspective of heterogeneous environment.Taking reader context in heterogeneous environment as the research object,this paper explores the method of constructing reader context model from five aspects:reader context model architecture,reader context definition,reader context modeling based on ontology,reader context acquisition,and reader context model updating.The reader context model in heterogeneous environment proposed in this paper has been greatly improved in depth and breadth,and can provide a strong guarantee for accurate personalized service of digital resources.
