Label determination method and device, information recommendation method and device, equipment and storage medium

The embodiment of the invention discloses a label determination method, an information recommendation method and device, equipment and a storage medium, and relates to the technical field of computers. The label determination method comprises the following steps: determining the similarity between current information to be stored and each piece of information in a preset information base, and for each preset similarity threshold in a preset similarity threshold set, determining a target in-library information set corresponding to the current preset similarity threshold from the preset information base, a sub-tag corresponding to a current preset similarity threshold value is determined based on the target multi-granularity tag of the in-library information in the target in-library information set, and the similarity of the in-library information in the target in-library information set is greater than the current preset similarity threshold value; and determining a multi-granularity label of the current infor
