The invention discloses a user evaluation method and device and a storage medium. The method comprises the steps of obtaining corresponding detail data according to user information; extracting data features from the detailed data; inputting the data features into an evaluation model to obtain a prediction probability output by the evaluation model; wherein the evaluation model is obtained by fusing a plurality of different types of sub-evaluation models according to corresponding weights; each sub-evaluation model is obtained by training with partially similar training features; and performing score conversion on the prediction probability, and evaluating the user by using a score obtained by conversion. Through the method, the accuracy of user evaluation by the evaluation model can be improved. 本申请公开了一种用户评估方法、装置及存储介质，该方法包括：根据用户信息获取对应的明细数据；从明细数据中提取出数据特征；将数据特征输入至评估模型，得到评估模型输出的预测概率；其中，评估模型是通过多个不同类型的子评估模型按照相应权重融合得到；每一子评估模型是利用部分相似的训练特征训练得到；对预测概率进行分数转换，利用转换得到的分数对用户进行评估。通过上述方法，能够提高评估模型对用户评估的准确性。
