摘要: 文中分析了多媒体数据源质量评估的多个关键因素,提出了一种针对于多媒体数据源的质量估计模型.模型从合时性、资源数量、使用数量、信息丰富度等四个维度对数据源质量进行了质量评估,并对源质量计算中的规范化方法进行了改进.实验证明,利用该模型对数据源质量进行估计具有很好的准确性和可操作性.Abstract: We analyse the key factors of quality assessment of web multimedia data sources and propose a new model to estimate the quality of web multimedia data sources.The model estimate the quality of data source from four dimensions:Timeliness,Resources Quantity,Use Quantity,Content Richness and improve the standardized method.The experiment result shows that the quality model is of good veracity and operability to evaluate the quality of multimedia web data sources.
