As shown in fig. 1, the recommendation method for the live broadcast room may include the following steps:
The historical watch sequence may be a list of account identifications of anchor accounts in a time period of a specified length, for example, it may be a list of IDs of anchors watched by the current user watch account within 90 days.
It should be noted that, in the history viewing sequence, the IDs of the respective anchor may be sorted according to a certain time sequence, for example, according to a time length from the current time, that is, if the viewing time of any anchor is closer to the current time, the position of the anchor in the history viewing sequence is further forward.
The target anchor may be a latest anchor selected currently in the history anchor sequence, that is, the user viewing time corresponding to the target anchor is later than the user viewing times corresponding to the other anchors in the history anchor sequence.
Optionally, the historical viewing sequence corresponding to the current viewing account may be obtained from the distributed cache.

And 104, merging and removing the duplicate of the N similar anchor lists to determine a recommended anchor list.
In order to finally determine the anchor list of interest recommended for the user, in the application, merging and deduplication processing needs to be performed on the N similar anchor lists, that is, the N similar anchor lists are merged and filtered to obtain a unique recommended anchor list.
In the embodiment of the application, account identifiers of N target anchor are obtained from a historical watching sequence, wherein the watching time of users corresponding to the N target anchor is later than that of users corresponding to other anchor in the historical watching sequence, N is a positive integer larger than 1, N first feature vectors corresponding to the account identifiers of the N target anchor are obtained, then a similar anchor list corresponding to each target anchor is determined from the online anchors according to the similarity between the N first feature vectors and second feature vectors corresponding to each online anchor, and finally the N similar anchor lists are combined and deduplicated to determine a recommended anchor list. Therefore, the live broadcast room in which the user is interested can be recalled from the online live broadcast room candidate pool with real-time content change according to the historical broadcast watching information, personalized and accurate recommendation for the user is achieved, and the requirement of the user on broadcast watching is met.
