An embodiment of the present invention provides a bullet screen display method, and fig. 1 is a schematic flow chart illustrating an implementation of the bullet screen display method provided in the embodiment of the present invention, as shown in fig. 1, the method mainly includes the following steps:
step S101: and acquiring a bullet screen set containing a plurality of bullet screens in the video unit playing time period.
Here, after the user sends the barrage through the terminal, the barrage is uploaded to the server, and the terminal acquires a barrage set including a plurality of barrages in the video unit playing time period from the server.
It should be noted that the unit playing time period may be preset, for example, 5 minutes or a single bullet screen full screen moving time, and the whole playing time of the video may be divided according to the unit playing time period.
Step S102: and based on the similarity among the bullet screens, aggregating the bullet screens with the concentrated similarity meeting the preset conditions to obtain each bullet screen subset.
In practical application, the terminal can judge according to the similarity between the bullet curtains, screen out the bullet curtain that satisfies the preset condition, aggregate the bullet curtain that obtains screening. For example, the preset condition may be that the similarity between the bullet screens is greater than 60%, and then the similarity between any two converged bullet screens is greater than 60% by determining whether the similarity between the bullet screens in the bullet screen set is greater than 60%.
In an embodiment, the terminal may aggregate the bullet screens whose bullet screen centralized similarity satisfies the preset condition in the following manner: calculating the similarity between the bullet screens in the bullet screen set; and based on the result of the similarity calculation, carrying out grade division on the bullet screens so as to aggregate bullet screens with the same grade to obtain bullet screen sets with different grades.
In practical application, the terminal can obtain the similarity between the bullet screens by acquiring the vector sum corresponding to each bullet screen and performing the cosine value operation of the included angle on the vector sum of any two bullet screens.
It should be noted that, the terminal may obtain the vector sum corresponding to the bullet screen by extracting the main words of the bullet screen and calculating the sum of the vectors corresponding to the main words of the bullet screen, for example, the bullet screen is "like this movie", and the main words are extracted as "like" and "movie", where the vector corresponding to "like" is (1,1), the vector corresponding to "movie" is (2,3), and then the vector sum corresponding to "like this movie" is (3, 4). And performing cosine value operation on the vector sum of any two bullet screens, wherein the range of the operation result is between 0 and 1, and 1 represents that the similarity is the highest and represents that the similarity is 100%.
In practical application, the terminal performs grade division on the barrage based on the result of the similarity calculation to aggregate barrages of the same grade, and the method comprises the following steps: the terminal extracts the bullet screens with the similarity larger than the similarity threshold value in the bullet screen set based on the result of the similarity calculation; determining a similarity interval where the similarity between the extracted bullet screens corresponding to the bullet screens is located; and grading the barrage according to the determined corresponding relation between the similarity interval and the preset similarity interval and grade to aggregate barrages with the same grade.
In an embodiment, a similarity threshold is preset, whether the similarity between the bullet screens corresponding to the bullet screens is greater than the preset similarity threshold is judged, if so, the bullet screens are classified as synonymous bullet screens, and the synonymous bullet screens are extracted. And performing grade division on the bullet screens according to the determined corresponding relation between the similarity interval and the preset similarity interval and grade, for example, dividing the similarity interval into 60% -75%, 75% -90% and 90% -100%, which respectively correspond to a low grade, a medium grade and a high grade, and if the similarity between two bullet screens is 80%, determining that the corresponding similarity interval is 75% -90%, dividing the two bullet screens into the medium grade.
Step S103: and according to a preset display strategy, transversely partitioning the bullet screen display area of the video to obtain at least two display areas.
It should be noted that, the terminal performs horizontal partition on the bullet screen display area of the video to obtain at least two display areas, which may be divided equally or in any proportion; the bullet screen display area of the video can be the whole display area of the video, or can be a partial display area of the video, such as the upper half of the display area of the video.
In an embodiment, the terminal may determine the number of the display areas according to the corresponding grade of the bullet screen in the bullet screen subset, and for the bullet screen with the higher grade corresponding to the bullet screen in the bullet screen subset, the divided display areas are more, so that the terminal can display more bullet screens within the same bullet screen time. For example, if the corresponding grade of the bullet screen in the bullet screen subset is a low grade, the bullet screen in the bullet screen subset is displayed in the two display areas, and if the corresponding grade of the bullet screen in the bullet screen subset is a high grade, the bullet screen in the bullet screen subset is displayed in the three display areas.
Step S104: for each bullet screen subset, respectively executing: and displaying the bullet screens in the bullet screen subsets in the at least two display areas according to the mode of displaying different bullet screens in different display areas.
In one embodiment, the terminal receives an aggregation instruction for the bullet screen; and responding to the aggregation instruction, and displaying the bullet screens in the bullet screen subsets in the at least two display areas.
In practical application, if a user needs to start a bullet screen aggregation function, an aggregation instruction aiming at the bullet screen is sent to a terminal, and the terminal receives the aggregation instruction and displays the bullet screens in bullet screen subsets in at least two display areas; if the user does not need to start the bullet screen aggregation function, the aggregation instruction aiming at the bullet screen can not be sent to the terminal, and the terminal does not receive the aggregation instruction, so that the bullet screen concentrated in the bullet screen display area of the screen can be directly displayed.
In one embodiment, the bullet screens in the bullet screen subset can be displayed in the adjacent first display area and the second display area according to the following modes:
controlling and displaying the first bullet screen, enabling the first bullet screen to enter from one end of the first display area, and monitoring at least one of the following movement parameters of the first bullet screen: moving time and moving distance; when the movement parameter of the first bullet screen is determined to accord with the preset movement condition, the first bullet screen is hidden and the second bullet screen is displayed, so that the first bullet screen is moved to the other end of the first display area and disappears, and when the first bullet screen disappears, the second bullet screen enters the one end of the second display area.
In practical application, when the terminal detects that the moving time or the moving distance of the first bullet screen meets the preset time or the preset distance, the first bullet screen is hidden and the second bullet screen is displayed. For example, as shown in fig. 2, the bullet screen "high energy warning" enters from the right side of the first display area, and when it is detected that the moving distance of the first bullet screen is equal to the width of the first display area, the bullet screen "high energy warning" is hidden, and the bullet screen "front high energy warning" is displayed in the second display area.
In an embodiment, the bullet screens in the bullet screen subset can be displayed in the adjacent first display area and the second display area in the following manner:
and the first bullet screen enters from one end of the first display area, and the second bullet screen enters from one end of the second display area. For example, as shown in fig. 3, the bullet screen "high energy warning" enters from the right side of the first display area, and the bullet screen "front high energy warning" enters from the right side of the second display area. Wherein, the bullet curtain can get into from the left end that corresponds the show area, moves to the right-hand member and disappears, perhaps gets into from the right-hand member that corresponds the show area, moves to the left end and disappears.
In one embodiment, the first display area includes at least one first bullet screen track and the second display area includes at least one second bullet screen track.
It should be noted that each display area includes one or more bullet screen tracks for displaying one or more bullet screens, wherein the multiple bullet screens are displayed in an aligned manner, or in a staggered manner, for example, two bullet screen columns shown in fig. 4 are displayed in an aligned manner, and two bullet screens shown in fig. 5 are displayed with one character therebetween.
In an embodiment, when it is determined that the movement parameter of the first bullet screen meets the preset movement condition, the first bullet screen is hidden and the second bullet screen is displayed, which can be completed in the following manner:
when the moving time of the first bullet screen reaches the set time and/or the moving distance of the first bullet screen reaches the set distance, hiding the first bullet screen and displaying the second bullet screen, so that the first bullet screen disappears when moving from the first end of the first bullet screen track to the second end of the first bullet screen track along the first bullet screen track after entering from the first end of the first bullet screen track, and the second bullet screen enters from the first end of the second bullet screen track while disappearing; the second end of the first bullet screen track is connected with the first end of the second bullet screen track in physical position or transversely spaced by a preset number of character lengths.
For example, as shown in fig. 6, divide video bullet screen display area into two display areas, bullet screen "the place ahead high energy" gets into the screen from the orbital right-hand member of first bullet screen, move left along first bullet screen track, when detecting that the displacement distance of first bullet screen reaches the orbital length of first bullet screen, hide bullet screen "high energy early warning", make bullet screen "high energy early warning" disappear at the orbital left end of first bullet screen, and when bullet screen "high energy early warning" disappears, bullet screen "the place ahead high energy early warning" gets into the screen from the orbital right-hand member of second bullet screen, move left along second bullet screen track, disappear from the orbital left end of first bullet screen. Wherein, a character space is arranged between the left end of the first bullet screen track and the right end of the second bullet screen track.
In an embodiment, the bullet screens in the bullet screen subset can be displayed in the adjacent first display area and second display area according to the following modes: and when the first bullet screen or the second bullet screen disappears, a third bullet screen enters from one end of the first display area.
In practical application, can be when first bullet curtain disappears from the one end in first show area, the third bullet curtain gets into from the one end in first show area, wherein, the one end that the third bullet curtain got into can be the same with the one end that first bullet curtain got into, also can be different, as shown in fig. 7, when bullet curtain "high energy early warning" disappears from the left end in first show area, bullet curtain "the place ahead high energy early warning" gets into from the right-hand member in first show area. Or, the third bullet screen enters from one end of the first display area while the second bullet screen disappears from one end of the second display area, as shown in fig. 8, the "front high-energy warning" bullet screen enters from the right end of the first display area while the "high-energy warning" bullet screen disappears from the left end of the second display area.
In one embodiment, the terminal filters the barrage in the barrage subset based on at least one of the first filtering rule and the second filtering rule; displaying the bullet screens in the filtered bullet screen subsets in the at least two display areas; the first filtering rules represent the text length of the bullet screen, and the second filtering rules represent the quantity of the bullet screen.
Here, the terminal may filter the bullet screens in the bullet screen subset based on the first filtering rule by: judging whether the character length of the bullet screen is larger than a character length threshold value corresponding to the display area or not; and when the bullet screen is determined to be larger than the preset value, rejecting the bullet screen.
It should be noted that the text length threshold may be determined according to the width of the corresponding display area, for example, the bullet screen display area of the video is divided into two display areas, and then the text length of the bullet screen cannot be greater than the full-screen width of 1/2, so that by removing the bullet screen whose text length exceeds the text length threshold, the problem that the space of the bullet screen is narrow and the user experience is affected when the bullet screen is displayed in a partitioned manner is solved.
In practical application, the terminal filters the bullet screen in the bullet screen subset based on the second filtering rule, including: sequencing the bullet screens in the bullet screen subset according to the number of the bullet screen characters; and rejecting the bullet screens with the largest number of characters in the sequencing result until the number of the bullet screens is smaller than the threshold value of the number of the bullet screens. For example, the threshold of the number of bullet screens is set to 4, and four bullet screens with the minimum number of words are screened out from the bullet screens in the bullet screen subset according to the principle that the number of words of the bullet screens is less and is preferred.
It should be noted that the bullet screen quantity threshold may be set according to the number of the display areas, for example, the bullet screen display area is divided into two display areas, the bullet screen quantity threshold is set to 4, the bullet screen display area is divided into three display areas, and the bullet screen quantity threshold is set to 6. The number of the display areas is determined according to the similarity between the bullet screens corresponding to the bullet screens in the bullet screen subset, and the higher the similarity is, the more the number of the divided display areas is. From this, to the bullet screen that the similarity is high, can show the bullet screen of more pieces of quantity in same bullet screen time, the pollution of reduction bullet screen that can bigger degree.
In an embodiment, the bullet screen display area can be divided longitudinally according to the levels, so that each display area comprises at least two longitudinal display areas with different levels; and displaying the corresponding bullet screens in the longitudinal areas of the at least two display areas according to the grades of the bullet screens.
In practical application, the bullet screens with higher levels are displayed in the lower area of the display area, and the bullet screens with lower levels are displayed in the upper area of the display area, so that a user can pay more attention to the bullet screens with lower levels, and pay less attention to the bullet screens with higher levels. For example, as shown in fig. 9, the bullet screen display area of the video is divided into three longitudinal display areas, which correspond to three different levels, respectively, and the low-level bullet screen is displayed in the upper area of the longitudinal direction of the screen, the middle-level bullet screen is displayed in the middle area of the longitudinal direction of the screen, and the high-level bullet screen is displayed in the lower area of the longitudinal direction of the screen.

Therefore, the embodiment of the invention realizes the display of the aggregated barrage in different partitions, on one hand, the barrage is classified through aggregation, and the barrage is displayed according to the classification, so that a user can quickly find interesting contents, and on the other hand, the display effect of the barrage can be more diversified due to the fact that each partition independently displays the barrage.
An embodiment of the present invention provides a bullet screen display method, and fig. 10 is a schematic diagram illustrating an implementation flow of the bullet screen display method provided in the embodiment of the present invention, as shown in fig. 10, the method mainly includes the following steps:
step S201: and acquiring a bullet screen set containing a plurality of bullet screens in the video unit playing time period.
In practical application, a terminal can acquire a plurality of barrages in a video unit playing time period to form a barrage set; the server may also acquire a plurality of barrages of the video unit playing time period, and send the barrage set including the plurality of barrages to the terminal, and the terminal may receive the barrage set including the plurality of barrages of the video unit playing time period.
It should be noted that the unit playing time period may be preset, for example, 5 minutes or a single bullet screen full screen moving time, and the whole playing time of the video may be divided according to the unit playing time period.
Step S202: and calculating the similarity between the bullet screens in the bullet screen set.
In an embodiment, the terminal may obtain the similarity between the bullet screens by obtaining the vector sum corresponding to each bullet screen and performing cosine value operation on the vector sum of any two bullet screens.
In practical application, the corresponding vector sum of each bullet screen can be obtained by extracting the stem words of the bullet screen, and determining the coordinates of all the stem words of the bullet screen according to the corresponding relation between the stem words and the coordinates in the established synonym library, so that the corresponding vector sum of the bullet screens is determined, the cosine value of the vector sum of any two bullet screens is calculated, and the similarity of the two bullet screens can be obtained.
Here, the synonym library is a system for performing unique plane coordinate (x, y) labeling on all synonym groups, and synonyms such as "like" and "like" can be classified into one class, namely coordinate labeling (1, 1); the words "movie", etc. can be grouped into one category, coordinates (2, 3). And summing the coordinates corresponding to all the main words of the bullet screen, namely obtaining the vector sum corresponding to the bullet screen, for example, if the bullet screen is like the film, extracting the main words as like and film, wherein the coordinates corresponding to like are (1,1), the coordinates corresponding to film are (2,3), and the vector sum corresponding to like the film is (3, 4).
It should be noted that, the cosine value operation of the included angle is performed on the vector sum of any two bullet curtains, and the range of the operation result is between 0 and 1, where "1" represents the highest similarity, and represents that the similarity is 100%. And only the bullet screen containing the Chinese characters can be subjected to similarity calculation, and for the bullet screen not containing the Chinese characters, complete matching classification is only performed.
Step S203: and extracting the bullet screens with the similarity greater than the similarity threshold value in the bullet screen set based on the result of the similarity calculation.
In an embodiment, a similarity threshold is preset, whether the similarity between the bullet screens corresponding to the bullet screens is greater than the preset similarity threshold is judged, if so, the bullet screens are classified as synonymous bullet screens, and the synonymous bullet screens are extracted. For example, all bullet screens satisfying a similarity of greater than 60% between bullet screens can be classified as synonymous bullet screens.
Step S204: and grading the extracted bullet screen according to the corresponding relation of the preset similarity interval pre-grades.
And performing grade division on the bullet screens according to the determined corresponding relation between the similarity interval and the preset similarity interval and grade, for example, dividing the similarity interval into 60% -75%, 75% -90% and 90% -100%, which respectively correspond to a low grade, a medium grade and a high grade, and if the similarity between two bullet screens is 80%, determining that the corresponding similarity interval is 75% -90%, dividing the two bullet screens into the medium grade.
Step S205: and displaying the bullet screen in a display area corresponding to the grade according to the grade of the bullet screen.
In one embodiment, an aggregation instruction for the bullet screen is received; and responding to the aggregation instruction, and displaying the bullet screen in a display area corresponding to the grade according to the grade to which the bullet screen belongs.
In practical application, if a user needs to start a bullet screen aggregation function, an aggregation instruction for the bullet screen is sent to a terminal, the terminal receives the aggregation instruction, and the bullet screen is displayed in a display area corresponding to the level; if the user does not need to start the bullet screen aggregation function, the aggregation instruction aiming at the bullet screen can not be sent to the terminal, and the terminal does not receive the aggregation instruction, so that the bullet screen concentrated in the bullet screen display area of the screen can be directly displayed.
In one embodiment, according to the level, the barrage display area of the video is divided longitudinally; and simultaneously displaying the corresponding bullet screens in the display areas of all the grades according to the grades of the bullet screens.
In practical application, the bullet screens with higher levels are displayed in the lower area of the display area, and the bullet screens with lower levels are displayed in the upper area of the display area, so that a user can pay more attention to the bullet screens with lower levels, and pay less attention to the bullet screens with higher levels. For example, the barrage is divided into three levels, the barrage display area of the video is longitudinally divided into three areas, the barrage with the lower level is displayed in the upper area of the longitudinal screen partition, the barrage with the middle level is displayed in the middle area of the longitudinal screen partition, and the barrage with the higher level is displayed in the lower area of the longitudinal screen partition. Wherein, the bullet screen of different grades can appear with the mode of row alignment, also can appear in crisscross mode, can separate a bullet screen space between the bullet screen track of different grades.
In one embodiment, at least two bullet screen tracks corresponding to the grades are determined according to the grades to which the bullet screens belong; and respectively displaying the bullet screens of all the grades through the at least two bullet screen tracks corresponding to all the grades.
In practical application, can show the bullet screen at the corresponding at least two bullet screen tracks of each grade simultaneously, to the higher bullet screen of grade, the track figure of dividing is more, makes it can show more bullet screens in same bullet screen time. For example, the bullet screen is divided into three levels, namely, a low level, a middle level and a high level, wherein the low level and the middle level correspond to two bullet screen tracks, and the high level corresponds to three bullet screen tracks. Wherein, can keep the interval of at least one character length between two bullet screen tracks that every grade is adjacent, when placing the bullet screen characters of adjacent section and appearing simultaneously, influence the user and distinguish different bullet screens.
In an embodiment, the at least two bullet screen tracks corresponding to each grade are used for respectively displaying bullet screens of each grade, and the following display modes can be adopted:
first bullet curtain gets into from the orbital one end of first bullet curtain, moves extremely disappearance during the orbital other end of first bullet curtain to when disappearing, the second bullet curtain is in the orbital one end of second bullet curtain gets into, moves extremely disappearance during the orbital other end of second bullet curtain. For example, when two bullet screen tracks are determined, when two bullet screens are displayed simultaneously, a first bullet screen enters a screen from the right side of the first bullet screen track, and is removed from the left side, when the bullet screen moves to the left side of the first bullet screen track, a second bullet screen enters the screen from the right side of the second bullet screen track, and the bullet screen is removed after the bullet screen moves to the left side of the second bullet screen track.
It should be noted that each bullet screen track can display one or more bullet screens, for example, two bullet screen tracks are determined, when four bullet screens are displayed simultaneously, the first and three bullet screens enter the screen from the right side of the first bullet screen track and are removed from the left side, and when the bullet screen moves to the left side of the first bullet screen track, the second and four bullet screens enter the screen from the right side of the second bullet screen track until the bullet screen moves to the left side of the second bullet screen track and is removed.
In one embodiment, displaying the bullet screen in a display area corresponding to a grade according to the grade to which the bullet screen belongs includes: filtering the barrages of all levels respectively based on at least one of the first filtering rule and the second filtering rule; displaying the filtered barrages of all the grades in the areas corresponding to the grades; the first filtering rules represent the text length of the bullet screen, and the second filtering rules represent the number of the bullet screen at the current level.
In practical application, based on a first filtering rule, the bullet screens of all levels are respectively filtered, and whether the bullet screens are larger than the character length threshold corresponding to the level to which the bullet screens belong can be judged; and when the bullet screen is determined to be larger than the preset value, rejecting the bullet screen.
It should be noted that the text length threshold may be determined according to the number of bullet screen tracks corresponding to each level, for example, the level corresponds to two bullet screen tracks, and then the text length of the bullet screen cannot be greater than the full-screen width of 1/2, so that by removing the bullet screen whose text length exceeds the text length threshold, the problem that the user experience is affected because the bullet screen appears to be narrow in space when being displayed in segments is solved.
In practical application, based on the second filtering rule, the barrages of all levels are respectively filtered, and the barrages of all levels can be sorted according to the number of characters of the barrages; and respectively eliminating the bullet screens with the largest number of characters in each grade until the number of the bullet screens in each grade is smaller than the threshold value of the number of the bullet screens corresponding to the grade. For example, the number threshold of the bullet screens corresponding to the high level is set to 4, and four bullet screens with the minimum number of words in the bullet screens are screened out from the bullet screens of the high level according to the principle that the number of words in the bullet screens is small and is preferred. Wherein, to the higher bullet screen of grade, the quantity threshold value that sets up is big more, makes it can show the bullet screen of more numbers at same bullet screen time, the pollution of reduction bullet screen that can bigger degree.
Therefore, the bullet screen is displayed in the display area corresponding to the grade according to the grade to which the bullet screen belongs, so that a user can pay more attention to the bullet screen with low similarity, and more different information can be obtained.
