摘要
用户兴趣图谱是实现智能代理与主动服务的基本依据 .而广播型网格的用户兴趣图谱有其自身的特点 .本文研究了UCL(UniformContentLocator)在广播型网格中接收端的应用机制 ,建立了UCL解析、数据流控制和UCL应用机制 ,提出了建立基于UCL的用户兴趣图谱的方法 ,分析了信息的媒体结构与本体结构的特点 ,研究了相互间转换和在用户肖像模型建立过程中的作用 .利用实验建立的广播网格环境验证了该方法的有效性 .
User Interest Spectrum (UIS) is the foundation of UCL(Uniform Content Locator) agent and active service in the broadcasting grid, which has many characteristics itself. UCL application mechanisms in the grid terminal are studied, such as the UCL resolution, the controlling of data stream, and the UCL application mechanism. At the same time, the method to build the UIS is put forward meanwhile, the medium framework and the ontological one of information are analyzed, including the characteristics, interchange and the effect of establishing the user profiles. Laboratory simulations demonstrate its feasibility and validity in the broadcasting grid.
