User satisfaction evaluation method and device

The embodiment of the invention provides a user satisfaction evaluation method and device. The method comprises the following steps: acquiring signaling data of a user in a target range, and extracting N pieces of preset index data in the signaling data; wherein N is greater than or equal to 2; clustering the coordinate points of each user according to a preset clustering algorithm to obtain a preset number of user groups; wherein the coordinate points are coordinate points in an N-dimensional space established by N pieces of preset index data of the user; and performing satisfaction samplingon each user group according to a preset rule to obtain a satisfaction evaluation value meeting a preset error rate requirement. According to the embodiment of the invention, the problem of insufficient coverage of obtaining user satisfaction by an operator in the prior art is solved. 本发明实施例提供一种用户满意度评估方法及装置。所述方法包括：获取目标范围内的用户的信令数据，提取所述信令数据中的N个预设指标数据；其中，N大于或等于2；根据预设聚类算法，将每个所述用户的坐标点聚类得到预设数目个用户群；其中，所述坐标点为以所述用户的N个预设指标数据建立的N维空间
