摘要: 为了提高Internet环境下构件选择的有效性,提出一种将场景匹配技术应用于构件选择的方法.首先,结合Internet环境的特点,将构件的可信性划分为可靠性、可用性和时效性,建立起构件可信性评估的一体化模型;其次,给出场景的定义和场景匹配度的计算方法;接着,将历史评价信息和场景匹配引入构件选择逻辑,实现了系统环境和可信需求约束下的构件选择机制,并给出构件选择算法;最后,通过仿真实验,说明了基于场景匹配的构件选择方法的有效性和实用性.Abstract: In order to improve the effectiveness of component choosing under Internet,a scene matching technology is raised to be applied in component choosing.Firstly combining with characteristics of Internet environment,the component credibility is evaluated from three aspects of reliability,usability and timeliness.An integrated evaluation model is built for the component credibility.Secondly the definition of scene and the calculation method of scene matching degree are proposed.And then by introducing the history evaluation and scene matching information into the component choosing logic,the mechanism of component choosing is realized with constraints of environment and credibility demand.The component choosing algorithm is also designed.Finally through simulation experiments,it's shown that the component choosing method is valid and usable.
