基于Hasse图的体验品群推荐研究――以餐饮业为例
The Study on Experience Group Recommendation Based on Hasse Diagram――Take the Catering Industry as an Example

针对目标群体对属性偏好的冲突性及不相容性等特点,采用Hasse图进行多属性集结,同时,考虑异质性消费者对各属性的偏好程度随时间推移而发生变化,因而在静态多属性群推荐研究的基础上考虑属性偏好的动态性.结果显示:在采用Hasse图进行动态多属性群推荐时,该方法具有较强的鲁棒性.
In view of the characteristics of the attribute preferences conflict and incompatibility in the target groups,Hasse diagram is adopted for multi-attribute aggregation.At the same time,it is considered that the degree of heterogeneous consumer's preferences for each attribute changes with time.Therefore,the dynamic nature of attribute preference is considered on the basis of traditional static multi-attribute group recommendation research.The results show that the method has strong robustness when Hasse diagram is used for dynamic multi-attribute group recommendation
