Title
(EN) Recommended item determination method, device and apparatus, and storage medium
(ZH) 推荐项目确定方法、装置、设备及存储介质
Abstract
(EN) The embodiment of the invention discloses a recommended item determination method, device and apparatus, and a storage medium. The method comprises: aiming at each project set in the project library,according to the target user feature data corresponding to the target user and a recall model corresponding to the current project set, determining a corresponding recall item sequence, wherein the project library comprises at least three project sets corresponding to different popularity levels; grading and sorting the items in the recalled item sequence, and determining a first candidate item sequence; and carrying out score improvement processing on a target project corresponding to a first preset popularity level in the first candidate project sequence to obtain a second candidate projectsequence, wherein the first preset popularity level comprises a lowest popularity level, and a target recommendation project sequence corresponding to the target user is determined according to the second candidate project sequence. According to the technical scheme provided by the embodiment of the invention, the display frequency of the low-popularity project can be reasonably and accurately improved.
(ZH) 本发明实施例公开了推荐项目确定方法、装置、设备及存储介质。其中,该方法包括:针对项目库中的每个项目集合,根据目标用户对应的目标用户特征数据和与当前项目集合对应的召回模型,确定对应的召回项目序列,其中,项目库中包含至少三个对应不同热度等级的项目集合,对召回项目序列中的项目进行评分排序,并确定第一候选项目序列,对第一候选项目序列中的对应第一预设热度等级的目标项目进行分数提升处理,得到第二候选项目序列,其中,第一预设热度等级包括最低热度等级,根据第二候选项目序列确定与目标用户对应的目标推荐项目序列。本发明实施例提供的技术方案,可合理准确地提升低热度项目的展现频率。
