Question recall method and device, equipment and storage medium

The invention belongs to the technical field of search engines, and discloses a question recall method and device, equipment and a storage medium. The method comprises the steps of determining semantic vector features corresponding to a target query problem; obtaining a corresponding semantic vector set to be recalled according to the semantic vector features; and determining a recall problem according to the semantic vector set to be recalled so as to complete problem recall. In this way, the query problem is accurately recalled. According to the method, the semantic vector features of the query questions are calculated, the questions with the same matched semantics are recalled, the search intention of the user is accurately captured, results with similar semantics but unmatched literal surfaces can also be accurately recalled, and the recall rate is increased while the recall accuracy is improved. 本发明属于搜索引擎技术领域，公开了一种问题召回方法、装置、设备及存储介质。该方法包括：确定目标查询问题对应的语义向量特征；根据所述语义向量特征得到对应的待召回语义向量集；根据所述待召回语义向量集确定召回问题，以完成问题召
