一种函件推送方法、装置、计算机设备及存储介质

本申请公开了一种函件推送方法，属于人工智能技术领域，通过提取目标用户的特征，得到第一特征标签集合；在用户列表中查找与任意一个第一特征标签相匹配的用户，形成相关用户集合；提取相关用户集合的特征，得到第二特征标签集合；计算每一个第二特征标签的标签权重，并将标签权重大于预设阈值的第二特征标签确定为推送标签；将推送标签对应的关联产品的产品信息填入预设的函件模板，生成目标函件；将目标函件推送给目标用户。本申请还提供一种函件推送装置、计算机设备及存储介质。此外，本申请还涉及区块链技术，用户的历史函件和特征标签可存储于区块链中。本申请可以提高基于用户喜好的函件推送方式的匹配率，以匹配到偏好相似的相关用户。 The invention discloses a letter pushing method, and belongs to the technical field of artificial intelligence, and the method comprises the steps: extracting the features of a target user, and obtaining a first feature label set; searching a user matched with any one of the first feature tags in a user list to form a related user set; extracting features of the related user set to obtain a secondfeature tag set; calculating a label weight of each second feature label, and determining the second feature label of which the label weight is greater than a preset threshold as a push label; filling the product information of the associated product corresponding to the push label into a preset letter template to generate
