As shown in fig. 1, the present application provides a flowchart of a video interaction method for multiple terminals, which is applied to a server and includes steps S11-S14.
S11, responding to the interaction message of the target terminal aiming at the first video, and creating a video interaction scene which is used for displaying the first video.
In this embodiment of the present application, when a user views a first video in a target terminal, a specific operation may be performed to enable the target terminal to send an interaction message for the first video to a server, and the server creates a video interaction scene in the target terminal after receiving the interaction message, as shown in fig. 2.
S12, inquiring historical interaction data of a plurality of candidate terminals based on the video interaction scene, wherein interaction behaviors exist between the account numbers of the candidate terminals and the first video, and the interaction behaviors comprise direct interaction behaviors used for indicating that when the account numbers of the candidate terminals are executing interaction operations aiming at the first video.
In the embodiment of the application, the candidate terminal is an operation terminal of a user account that is simultaneously showing the first video. The account number of the candidate terminal and the first video have interaction behaviors, and in the embodiment, the interaction behaviors of the account number of the candidate terminal include direct interaction behaviors; the account number of the candidate terminal is indicated to execute the interaction operation for the first video when the target terminal sends the interaction message for the first video to the server. Consider that in practical applications, the interaction behavior of the account number of the candidate terminal with respect to the first video may not be completely synchronized with the interaction message. Therefore, the embodiment of the application preliminarily identifies the matching degree of the direct interaction behavior of the account number of the candidate terminal and the current interaction requirement of the target terminal by comparing the time coincidence rate of the interaction operation and the interaction message.
S13, matching the historical interaction data of the target terminal with the historical interaction data of the plurality of candidate terminals to obtain a matching result.
In the embodiment of the present application, the historical interaction data of the plurality of candidate terminals refers to a data record of interaction behavior of the candidate terminals for historical viewing video in a historical period. In the embodiment of the application, in order to meet the interaction requirement of the account number of the target terminal, a more accurate interaction object is obtained. And in the process of matching the objects, selecting historical watching videos of the interaction behaviors in the candidate terminals. And analyzing the preferred video types when the candidate terminals do interactive behaviors. Therefore, in the embodiment of the present application, in the history interaction data, only the video of the simple viewing action is made to the target terminal, and the video is not taken as the history interaction data, so as to perform the next judgment. Through the judgment and screening, more accurate matching results can be obtained.
In one possible implementation, the plurality of candidate terminals includes a first candidate terminal; in step S13, the historical interaction data of the target terminal and the historical interaction data of the plurality of candidate terminals are matched to obtain a matching result, which specifically includes steps S131 to S133 shown in fig. 3.

And judging and screening the historical interaction data of the target terminal in the same way as the historical interaction data of the candidate terminal. The video is only watched for the history of the existence of interaction behavior for the account of the target terminal as part of the historical interaction data of the target terminal in the embodiment of the present application. In the embodiment of the present application, for obtaining the target tag group, the following method is specifically referred to below.
In one possible implementation, as shown in fig. 4, the target tag group showing the preference of the target terminal is obtained based on the historical interaction data of the target terminal, and specifically includes steps S131a-S131c.
S131a, adopting keyword screening to obtain a plurality of labels from the historical interaction data of the target terminal and the coincidence degree of the labels.
Specifically, for a historical video with interactive behaviors of a target terminal, acquiring all tags of the historical interactive video based on audience custom tag evaluation and automatic tag pushing of a video platform; the higher the association degree between the tag and the historical interactive video is, the higher the overlap degree of the tag is. Before actually acquiring the label type of the first video and the overlap ratio of the label type of the first video, the label type with the too low overlap ratio can be screened by setting an overlap ratio threshold of the label.
In a possible implementation manner, the coincidence degree threshold of the tag is changed according to satisfaction of the account number of the target terminal on the matching result; when the number of the candidate terminals obtained in the matching result is large, the coincidence degree threshold of the label can be improved, so that fewer candidate terminals can meet the matching requirement; when the number of candidate terminals obtained in the matching result is small, the overlap ratio threshold of the tag can be reduced, so that more candidate terminals can meet the matching requirement.

Before and after correction, the mapping relation formula of the coincidence degree of the labels is as follows:
wherein ,
=
×
=1,2,3...
；
In the above formula, since the tag types of the historical interactive video of the target terminal are richer than those of the first video. And the tag class of the historical interaction video of the target terminal will include the tag type of the first video. Therefore, when correction repair is performed on the overlap ratio of the plurality of tags based on the overlap ratio of the tag type of the first video, only the tag appearing in the tag type of the first video can be repaired. The remaining labels, i.e. in the above formula
The overlap ratio of the corresponding label is kept unchanged.

Specifically, when the tag matching degree of the tags of the plurality of tag groups and the target terminal is smaller than the preset tag matching degree, which is obtained through the method. At the moment, the candidate terminals with direct interaction behaviors on the first video and the interaction requirement of the account numbers of the target terminals cannot be met are simply considered. Thus, to expand the scope of matching interactive objects, multiple alternative terminals for which there is indirect interaction with respect to the first video are queried.
