[0001] The present disclosure relates to the field of data processing, and in particular to a bullet screen display method, device, electronic device and storage medium. Background Art

[0002] At present, all multimedia platforms provide the barrage function. The imaginative barrage greatly enriches the viewing experience and fun of multimedia data, and has become an indispensable way for users to communicate. In the prior art, for the barrage of the same multimedia data, first, it can be displayed in sequence according to the display time of the barrage, and the barrages with the same display time are sorted according to their barrage quality and creation time, and displayed in sequence.

[0003] However, in some scenarios, users may repeatedly send barrages with the same or similar content within a period of time.

[0068] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0069] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0070] First, the implementation environment involved in the embodiments of the present application is described, and the implementation environment includes a terminal and a server, and the terminal and the server are connected via a communication network. In some embodiments, the terminal includes a first terminal and a second terminal.

[0071] The first terminal is used to send the barrage to be processed of the target multimedia data to the server. The user can send his own comments and feelings about the target multimedia data through the first terminal. After the server receives the barrage to be processed of the target multimedia data, it executes the barrage display method provided by the present application, and determines the repeated barrage corresponding to the barrage to be processed from the barrage of the target multimedia data according to the display time, and when the number of repeated barrages is greater than the preset number of repeated barrages, the barrage to be processed is used as the bottom barrage, wherein the repeated barrage matches the display time and the similarity with the barrage to be processed is greater than the preset similarity threshold.

[0072] The second terminal or the first terminal is further used to send a bullet screen display instruction to the server, so that the user can browse the bullet screen content of the target multimedia data while playing the target multimedia data through the second terminal or the first terminal. In response to the bullet screen display instruction for the target multimedia data, the server displays the target bottom bullet screen corresponding to any time when the number of bullet screens displayed at any time is less than the preset display number.

[0073] The above-mentioned terminal can be a terminal device in various forms such as a mobile phone, a tablet computer, a desktop computer, a portable laptop computer, etc., and the embodiments of the present application are not limited to this.

[0074] It is worth noting that the above-mentioned servers can be independent physical servers, or they can be server clusters or distributed systems composed of multiple physical servers. They can also be cloud servers that provide basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDN), as well as big data and artificial intelligence platforms.

[0075] Among them, cloud technology refers to a hosting technology that unifies hardware, software, network and other resources in a wide area network or local area network to realize data computing, storage, processing and sharing. Cloud technology is a general term for network technology, information technology, integration technology, management platform technology, application technology, etc. based on the cloud computing business model. It can form a resource pool, which is used on demand and flexible and convenient. Cloud computing technology will become an important support. The background services of the technical network system require a large amount of computing and storage resources, such as video websites, picture websites and more portal websites. With the high development and application of the Internet industry, in the future, each item may have its own identification mark, and all need to be transmitted to the background system for logical processing. Data of different levels will be processed separately. All kinds of industry data require strong system backing support, which can only be achieved through cloud computing.

[0076] In some embodiments, the above-mentioned server can also be implemented as a node in a blockchain system. Blockchain is a new application mode of computer technologies such as distributed data storage, peer-to-peer transmission, consensus mechanism, encryption algorithm, etc. Blockchain is essentially a decentralized database, a string of data blocks generated by cryptographic methods. Each data block contains a batch of network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block. Blockchain can include the underlying blockchain platform, the platform product service layer, and the application service layer.

[0077] In combination with the above implementation environment, the bullet screen display method provided by this application is described. Figure 1 It is a flowchart of a bullet screen display method according to an exemplary embodiment. The bullet screen display method includes the following steps.

[0078] In step S11, the barrage to be processed of the target multimedia data is obtained, and the barrage to be processed carries the corresponding display time.

[0079] At present, various multimedia platforms provide the barrage function. The imaginative barrage has greatly enriched the viewing experience and fun of multimedia data. For the barrage of the same multimedia data, first, they can be displayed in sequence according to the display time of the barrage. The barrages with the same display time can be sorted according to their barrage quality and creation time, and displayed in sequence.

[0080] However, in some scenarios, users may repeatedly send bullet comments with the same or similar content within a period of time. The sorting order of these bullet comments is basically the same. In addition, during the multimedia data playback process, the number of bullet comments that can be displayed at the same time is limited. In this case, Figure 2 As shown, if the repeated bullet comments are ranked higher, a large number of repeated bullet comments will be displayed, making the bullet comments monotonous and boring. Therefore, it is necessary to improve the method for displaying bullet comments.

[0081] In this application, the target multimedia data can be audio and video data, image data, text data, or live streaming data, without specific limitation. When browsing the target multimedia data, the user can send bullet comments at any time for interaction. After obtaining the bullet comments sent by the user, the server will use it as the pending bullet comments of the target multimedia data for subsequent processing.

[0082] The barrage to be processed carries the corresponding display time, which is the time when the barrage to be processed is displayed during the playback of the target multimedia data. Specifically, the display time can be the playback time of the target multimedia data when the user creates the barrage; it can also be the playback time of the target multimedia data when the user sends the barrage; it can also be the playback time of the target multimedia data when the server receives the barrage to be processed; in addition, the user can also specify the display time corresponding to the barrage to be processed, which is not specifically limited.

[0083] In step S12, according to the display time, a repeated barrage corresponding to the barrage to be processed is determined from the barrages of the target multimedia data; the repeated barrage matches the display time and the similarity with the barrage to be processed is greater than a preset similarity threshold.

[0084] In this step, a repeated bullet comment that matches the display time and has a similarity with the bullet comment to be processed greater than a preset similarity threshold can be determined from the bullet comments of the target multimedia data. The repeated bullet comment matches the display time of the bullet comment to be processed and has a high similarity, so the display effect presented is also similar.

[0085] Among them, matching with the display time may mean that the display time is the same as the display time of the barrage to be processed, or it may mean that the display time is close to the display time of the barrage to be processed, for example, the display time may be within the display period determined according to the display time of the barrage to be processed.

[0086] The similarity with the barrage to be processed can be calculated by using similarity algorithms such as cosine similarity, Pearson correlation coefficient similarity, Euclidean distance or modified cosine value, etc., without specific limitation. Furthermore, before calculating the similarity between barrages, the barrages can be pre-processed to clean redundant characters and garbled characters in the barrages, and to normalize the barrage content, etc., so as to make the calculation of similarity more accurate.

[0087] In one implementation method, repeated barrages corresponding to the barrages to be processed are determined from the barrages of the target multimedia data according to the display time, including: determining the display period of the barrages to be processed according to the display time; obtaining barrages with display times within the display period from the barrages of the target multimedia data as candidate barrages; calculating the similarity between the candidate barrages and the barrages to be processed, and taking the candidate barrages with similarities greater than a preset similarity threshold as the repeated barrages corresponding to the barrages to be processed.

[0088] That is to say, first determine the display period of the barrage to be processed according to the display time, and determine the candidate barrages whose display time is within the display period, and then use the candidate barrages whose similarity with the barrage to be processed is greater than the preset similarity threshold as the repeated barrages corresponding to the barrage to be processed. That is, within the display period of the barrage to be processed, the barrages with a high similarity to the barrage to be processed are the repeated barrages of the barrage to be processed. In this way, by determining the repeated barrages, it is convenient to subsequently count the number of repetitions of the repeated barrages and adjust their display, thereby realizing the diversification of barrage display.

[0089] For example, the display cycle can be a cycle determined by taking the display time of the barrage to be processed as the center; it can also be a cycle determined by taking the display time of the barrage to be processed as the starting time; it can also be a cycle determined by taking the display time of the barrage to be processed as the end time; the duration of each cycle can be 30 seconds or 1 minute, and can also be determined based on the dwell time of the barrage to be processed when it is displayed, and so on, without specific limitation.

[0090] In step S13, when the number of repeated bullet comments is greater than the preset number of repeated comments, the bullet comment to be processed is set as the bottom bullet comment.

[0091] In this step, after determining the repeated barrages corresponding to the barrages to be processed, the number of repeated barrages can be counted. It can be understood that if the number of repeated barrages is large, then if all the barrages to be processed and the repeated barrages are displayed, it is likely that the barrage content will be monotonous and boring.

[0092] Then, when the number of repeated barrages is greater than the preset number of repetitions, the barrage to be processed can be placed at the bottom, and the display order of the bottom barrages is relatively late. In this way, other barrages with lower similarity and more diversity can be displayed before the bottom barrages, which is conducive to improving the diversity of barrages of the target multimedia data.

[0093] Among them, the barrage to be processed can be treated as the bottom barrage by adding a bottom label to the barrage to be processed, or by storing the barrage to be processed in another barrage queue, so as to distinguish the bottom barrage from other barrages. Alternatively, other methods can be adopted, which are not specifically limited.

[0094] In step S14, in response to the barrage display instruction for the target multimedia data, when the number of barrages displayed at any time is less than the preset display number, the target bottom barrage is displayed, and the target bottom barrage is the bottom barrage whose display time corresponds to any time.

[0095] In this step, in response to the barrage display instruction for the target multimedia data, the barrage of the target multimedia data can be displayed, wherein, if the barrage to be processed is a bottom barrage, its display order is later. Usually, when the number of barrages displayed at any moment is less than the preset display number, the target bottom barrage whose display time corresponds to any moment will be displayed.

[0096] Specifically, in one implementation, when the number of repeated barrages is not greater than a preset number of repetitions, the barrage to be processed can be treated as a non-bottom barrage; further, in response to a barrage display instruction for the target multimedia data, when the number of barrages displayed at any moment is less than a preset display number, the target bottom barrage is displayed, including: in response to a barrage display instruction for the target multimedia data, based on the display time, a non-bottom barrage is displayed, and when the number of barrages displayed at any moment is less than a preset display number, the target bottom barrage is displayed.

[0097] That is to say, the display order of non-bottom barrages takes precedence over bottom barrages. In this way, if there are differentiated non-bottom barrages with low similarity to a large number of similar barrages, then these differentiated non-bottom barrages will be displayed more frequently, thereby avoiding the barrage content being monotonous and boring, which is conducive to improving the diversity of barrages in the target multimedia data.

[0098] like Figure 3 As shown, after adopting the barrage display method provided by the present application, the display effect of repeated barrages is that, among the preset number of barrages that can be displayed in each frame of the target multimedia data, even if the repeated barrages are sorted in an earlier order, only the preset number of repeated barrages are displayed, and other differentiated barrages are displayed as much as possible.

[0099] From the above, it can be seen that the technical solution provided by the embodiments of the present disclosure defines a preset number of repetitions of repeated barrages when displaying barrages of multimedia data. Repeated barrages within the preset number of repetitions can be displayed. If there are more repeated barrages, the repeated barrages greater than the preset number of repetitions will be sorted at the bottom. These bottom barrages will only be displayed when the number of barrages displayed at the current moment is small, thereby avoiding the effect of excessive screen swiping of repeated barrages and improving the diversity and interest of the barrages.

[0100] In some embodiments, it is possible to determine whether the bullet message to be processed is a bottom bullet message by caching, such as Figure 4 It is a flowchart of a bullet screen display method according to an exemplary embodiment. The bullet screen display method includes the following steps.

[0101] In step S21, the barrage to be processed of the target multimedia data is obtained, and the barrage to be processed carries the corresponding display time.

[0102] In this application, the target multimedia data can be audio and video data, image data, text data, or live streaming data, without specific limitation. When browsing the target multimedia data, the user can send bullet comments at any time for interaction. After obtaining the bullet comments sent by the user, the server will use it as the pending bullet comments of the target multimedia data for subsequent processing.

[0103] The barrage to be processed carries the corresponding display time, which is the time when the barrage to be processed is displayed during the playback of the target multimedia data. Specifically, the display time can be the playback time of the target multimedia data when the user creates the barrage; it can also be the playback time of the target multimedia data when the user sends the barrage; it can also be the playback time of the target multimedia data when the server receives the barrage to be processed; in addition, the user can also specify the display time corresponding to the barrage to be processed, which is not specifically limited.

[0104] In step S22, cache information of the target multimedia data is obtained; candidate repeated barrages of the target multimedia data are read from the cache information; similarity between the candidate repeated barrages and the barrages to be processed is calculated, and candidate repeated barrages with similarity greater than a preset similarity threshold are used as repeated barrages corresponding to the barrages to be processed; the candidate repeated barrages are repeated more than a preset number of times within the corresponding display cycle.

[0105] In this step, candidate repeated barrages of the target multimedia data can be read from the cache information of the target multimedia data, wherein the candidate repeated barrages are repeated more than a preset number of times within the corresponding display cycle, that is, barrages with a large number of repetitions within the display cycle, as candidate repeated barrages, have been pre-stored in the cache information of the target multimedia data.

[0106] In this way, when judging whether the barrage to be processed is a barrage that is repeated multiple times, you only need to obtain the barrage with a large number of confirmed repetitions from the cache information, and then compare the similarity between the candidate repeated barrage and the barrage to be processed, without having to obtain all the barrages of the target multimedia data, calculate the similarity one by one and count the number, thereby saving system resources and improving the efficiency of barrage processing.

[0107] The similarity with the barrage to be processed can be calculated by using similarity algorithms such as cosine similarity, Pearson correlation coefficient similarity, Euclidean distance or modified cosine value, etc., without specific limitation. Furthermore, before calculating the similarity between barrages, the barrages can be pre-processed to clean redundant characters and garbled characters in the barrages, and to normalize the barrage content, etc., so as to make the calculation of similarity more accurate.

[0108] In step S23, when there are repeated bullet comments, the bullet comments to be processed are placed at the bottom.

[0109] It can be understood that if there are repeated barrages, it means that there are a large number of barrages similar to the barrages to be processed. Therefore, if all the barrages to be processed and the repeated barrages are displayed, it is likely that the barrage content will be monotonous and boring.

[0110] Then, the barrage to be processed can be placed as the bottom barrage, and the display order of the bottom barrage is relatively late. In this way, other barrages with lower similarity and more diversity can be displayed before the bottom barrage, which is conducive to improving the diversity of barrages of target multimedia data.

[0111] Among them, the barrage to be processed can be treated as the bottom barrage by adding a bottom label to the barrage to be processed, or by storing the barrage to be processed in another barrage queue, so as to distinguish the bottom barrage from other barrages. Alternatively, other methods can be adopted, which are not specifically limited.

[0112] In step S24, when there are no repeated barrages, after a preset time length, based on the display time, the repeated barrages corresponding to the barrages to be processed are determined from the barrages of the target multimedia data; when the number of repeated barrages is greater than the preset number of repeated barrages, the barrage to be processed is placed as the bottom barrage and stored in the cache information as a candidate repeated barrage.

[0113] It can be understood that if there are no repeated bullet comments, it means that the number of bullet comments similar to the bullet comments to be processed is small, or it may be caused by statistical errors, then the bullet comments to be processed can be asynchronously calculated. That is to say, after the preset time, according to the display time, the repeated bullet comments corresponding to the bullet comments to be processed are determined from the bullet comments of the target multimedia data; when the number of repeated bullet comments is greater than the preset number of repeated comments, the bullet comments to be processed are placed at the bottom and stored in the cache information as candidate repeated bullet comments.

[0114] Among them, the preset duration can be 1 minute or 1 day. In this way, the candidate repeated barrages in the target multimedia data can be updated regularly without affecting the subsequent processing and display of the barrages to be processed, thereby further maintaining the barrage diversity of the target multimedia data and the system operation efficiency.

[0115] Among them, matching with the display time may mean that the display time is the same as the display time of the barrage to be processed, or it may mean that the display time is close to the display time of the barrage to be processed, for example, the display time may be within the display period determined according to the display time of the barrage to be processed.

[0116] In one implementation method, repeated barrages corresponding to the barrages to be processed are determined from the barrages of the target multimedia data according to the display time, including: determining the display period of the barrages to be processed according to the display time; obtaining barrages with display times within the display period from the barrages of the target multimedia data as candidate barrages; calculating the similarity between the candidate barrages and the barrages to be processed, and taking the candidate barrages with similarities greater than a preset similarity threshold as the repeated barrages corresponding to the barrages to be processed.

[0117] That is to say, first determine the display period of the barrage to be processed according to the display time, and determine the candidate barrages whose display time is within the display period, and then use the candidate barrages whose similarity with the barrage to be processed is greater than the preset similarity threshold as the repeated barrages corresponding to the barrage to be processed. That is, within the display period of the barrage to be processed, the barrages with a high similarity to the barrage to be processed are the repeated barrages of the barrage to be processed. In this way, by determining the repeated barrages, it is convenient to subsequently count the number of repetitions of the repeated barrages and adjust their display, thereby realizing the diversification of barrage display.

[0118] For example, the display cycle can be a cycle determined by taking the display time of the barrage to be processed as the center; it can also be a cycle determined by taking the display time of the barrage to be processed as the starting time; it can also be a cycle determined by taking the display time of the barrage to be processed as the end time; the duration of each cycle can be 30 seconds or 1 minute, and can also be determined based on the dwell time of the barrage to be processed when it is displayed, and so on, without specific limitation.

[0119] In step S25, in response to the barrage display instruction for the target multimedia data, when the number of barrages displayed at any time is less than the preset display number, the target bottom barrage is displayed, and the target bottom barrage is the bottom barrage whose display time corresponds to any time.

[0120] In this step, in response to the barrage display instruction for the target multimedia data, the barrage of the target multimedia data can be displayed, wherein, if the barrage to be processed is a bottom barrage, its display order is later. Usually, when the number of barrages displayed at any moment is less than the preset display number, the target bottom barrage whose display time corresponds to any moment will be displayed.

[0121] Specifically, in one implementation, when the number of repeated barrages is not greater than a preset number of repetitions, the barrage to be processed can be treated as a non-bottom barrage; further, in response to a barrage display instruction for the target multimedia data, when the number of barrages displayed at any moment is less than a preset display number, the target bottom barrage is displayed, including: in response to a barrage display instruction for the target multimedia data, based on the display time, a non-bottom barrage is displayed, and when the number of barrages displayed at any moment is less than a preset display number, the target bottom barrage is displayed.

[0122] That is to say, the display order of non-bottom barrages takes precedence over bottom barrages. In this way, if there are differentiated non-bottom barrages with low similarity to a large number of similar barrages, then these differentiated non-bottom barrages will be displayed more frequently, thereby avoiding the barrage content being monotonous and boring, which is conducive to improving the diversity of barrages in the target multimedia data.

[0123] like Figure 5 The figure shows a logic diagram of a bullet screen display method of an embodiment of the present application. Among them, the user terminal can send the bullet screen to be processed to the server through the bullet screen interface; the server determines whether the bullet screen to be processed is repeated in large quantities within the display period corresponding to its display time based on the cache information. If so, a bottom mark is added to the bullet screen to be processed, and it is stored in the bullet screen database as a bottom bullet screen. It can only be displayed when there are insufficient non-bottom bullet screens; if not, asynchronous calculation is performed on the bullet screen to be processed, and further judgment is made as to whether it is repeated in large quantities within the display period corresponding to its display time. If it is further judged as yes, a bottom mark is added to the bullet screen to be processed, and it is stored in the bullet screen database as a bottom bullet screen, and it is stored in the cache information.

[0124] Through many experiments, after adopting the barrage display method provided by this application, the number of repetitions of the barrage per minute was counted, and the data with the number of repetitions ranked from high to low at 99.5% were taken. The experimental results showed that the repetition index was reduced from 80 to about 40. Therefore, the phenomenon of excessive screen swiping of repeated barrages was improved.

[0125] From the above, it can be seen that the technical solution provided by the embodiments of the present disclosure defines a preset number of repetitions of repeated barrages when displaying barrages of multimedia data. Repeated barrages within the preset number of repetitions can be displayed. If there are more repeated barrages, the repeated barrages greater than the preset number of repetitions will be sorted at the bottom. These bottom barrages will only be displayed when the number of barrages displayed at the current moment is small, thereby avoiding the effect of excessive screen swiping of repeated barrages and improving the diversity and interest of the barrages.

[0145] Determining a display period of the to-be-processed bullet comment according to the display time;

[0147] The similarity between the candidate bullet comments and the bullet comments to be processed is calculated, and the candidate bullet comments whose similarity is greater than a preset similarity threshold are used as duplicate bullet comments corresponding to the bullet comments to be processed.

[0148] From the above, it can be seen that the technical solution provided by the embodiments of the present disclosure defines a preset number of repetitions of repeated barrages when displaying barrages of multimedia data. Repeated barrages within the preset number of repetitions can be displayed. If there are more repeated barrages, the repeated barrages greater than the preset number of repetitions will be sorted at the bottom. These bottom barrages will only be displayed when the number of barrages displayed at the current moment is small, thereby avoiding the effect of excessive screen swiping of repeated barrages and improving the diversity and interest of the barrages.
