Abstract:

文中提出一种基于灰色理论的用户满意度评价方法。基本思想:根据对各种类型的产品和对象(如旅社、酒店等)的评价具有相对性、不确定性和模糊性(这三种特性统称为灰色性)的特征,将用户满意度分为很满意,满意,一般,不满意和很不满意等五种类型,克服了已有方法将情感分为满意和不满意的粗粒度定性评价缺陷。构建了用户满意度灰色评估模型,为了扩大对各类型产品评价的适应性,引用了相似性情感词匹配词对和对象对应产品的对应性热点词匹配词对来构建用户对产品和对象的满意度评测指标。以实际产品为实验数据对象,仿真结果表明:提出的方法不仅能获得产品或对象的总体满意度结论值VB,还能得到各项评测指标(影响产品或对象的因素)的量化评估结论值VBi,有效解决了定性评价方法的不足,为消费者提供了更详细的消费指导,为商业机构提供了有针对性的生产销售措施。
