Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein.
FIG. 1 illustrates a flow chart of a video hinting method, performed by a computer processing device, according to an embodiment of the invention. The computer processing device may include a cell phone, a notebook computer, etc. As shown in fig. 1, the method comprises the steps of:
step 10: respectively determining the behavior heat of each time point according to the user behavior data of the video at a plurality of time points; the behavior heat is used for representing the interestingness of the user in interactive behaviors aiming at the video.
In one embodiment of the invention, the user behavior data corresponds to historical users watching the video. The user behavior data can comprise data corresponding to various behavior types such as user comments, barrage sending, sharing, praise, forwarding and @ and the like. The behavior heat is used for representing the interest degree of the user in performing the interactive behavior at each time point, specifically, the greater the interest degree of performing the interactive behavior is, the greater the engagement degree of the user in interacting with the video is, that is, when the interest degree of the user in interacting is higher, the greater the probability of the user behavior, that is, the greater the data volume or the occurrence frequency of the user behavior data is.
The behavior heat can be determined according to the quantity and/or frequency of the user behavior data, such as the quantity of user comments or the quantity of barrages sent by the user. The behavior heat may also be determined from the total amount or average frequency of behavior data for at least two of the aforementioned multiple behavior types.
Step 20: determining a target prompt point from the time points according to the behavior heat degree; the target prompt point comprises the time point when the change condition of the behavior heat degree meets a preset condition.
In one embodiment of the invention, in order that the prompting action on the target prompt point does not interrupt the immersive experience of the user, the change of the attention of the user can be determined according to the change of the behavior heat, specifically, the change of the behavior heat can comprise heat change smoothness, and the heat change smoothness is used for representing the intensity of the change of the behavior heat. The greater the smoothness of the heat change, the less drastic the change in the heat of behavior that characterizes the user, and therefore the user has a greater probability of being in an immersive viewing process, while the lesser the smoothness of the heat change, the more likely the user will have a shift in interactive interest, i.e., a transition from one mode of interactive behavior to another, such as a change in the user's attention. Specifically, the degree of heat change smoothness may be determined according to the change of the degree of heat of the behavior respectively corresponding to each of the adjacent time points.
And screening the time points according to the heat change smoothness, and determining the time points with relatively small heat change smoothness as target prompt points, wherein the time points with relatively small heat change smoothness represent that the user has the transition of an interactive behavior mode, and the attention of the user may have a fault, so that the user is in immersive experience with small probability, and at the moment, if the user is reminded, the watching experience of the user is not interrupted, and the user experience is better.
Step 201: and determining selectable prompt points and corresponding heat degree change smoothness from the time points according to the behavior heat degree. The popularity variation smoothness is used for representing the intensity of the behavior popularity variation of the user.
In an embodiment of the present invention, considering that a time point with a low activity popularity generally corresponds to a video frame with low user attention and low interaction interest, and therefore, prompting at the time point does not well promote the user to generate an interaction activity, a time point with an activity popularity greater than a preset threshold value in all time points may be screened out as an optional prompt point, so as to further determine a target time point for actually performing an interaction according to the optional prompt point.
The heat change smoothness is used to characterize the severity of the change in the heat of behavior. The greater the smoothness of the heat change, the less drastic the change in the heat of behavior that characterizes the user, and therefore the user has a greater probability of being in an immersive viewing process, while the lesser the smoothness of the heat change, the more likely the user will have a shift in interactive interest, i.e., a transition from one mode of interactive behavior to another, such as a change in the user's attention. Therefore, the degree of heat change smoothness can be determined according to the change situation of the behavior heat corresponding to each adjacent time point.
Step 202: and determining the selectable prompt point which is positioned at a front preset position after the heat change smoothness is sorted in an ascending order as the target prompt point.
In an embodiment of the present invention, as described above, the smoothness of the heat change represents that the user has a transition of an interactive behavior mode, and the attention of the user may have a fault, so that the user has a low probability of being in an immersive experience. Therefore, the selectable time point of the minimum preset bit before the heat degree change smoothness can be determined as the target cue point.
In yet another embodiment of the present invention, step 20 further comprises:
step 203: and arranging the time points according to the descending order of the behavior heat degree, and determining the time points of preset bits before arrangement as the selectable prompt points.
In an embodiment of the invention, the behavior heat reflects the interaction interest of the user, and the greater the behavior heat, the more intense the interaction atmosphere of the user group at the time point is, so that the reminding is performed at the time point, the current user can be added into the interaction behavior trend of the public, the interaction probability of the user is improved, and under the drive of the addition of the interaction behavior trend, the user interaction has a higher probability to receive the feedback of other users, and the user experience is better.
In one embodiment of the present invention, step 20 further comprises:
step 202: and determining the predicted behavior heat of the selectable cue points.
In one embodiment of the invention, the predicted behavior heat is used to characterize the behavior heat in the ideal case of the selectable cue point, i.e. when no change occurs in the behavior heat. The predicted behavior heat may be a preset value or may be determined according to an average value of the behavior heat at all time points.
Thus, in a further embodiment of the present invention, step 202 further comprises:
step 2021: and carrying out weighted summation processing on the actual behavior data quantity and the predicted behavior data quantity of the last time point adjacent to the selectable prompt point to obtain the predicted behavior heat.
In one embodiment of the present invention, the preset initial smoothness may be used as a weighted sum. Specifically, for each optional prompt point t, its corresponding predicted behavior heat y t Can be expressed as: y is t =ax t +(1-a)y t-1 Wherein a is the initial smoothness, x t Is the actual behavior data volume at time t.
Step 203: and determining a smoothness relative error and a smoothness absolute error corresponding to the selectable prompt point according to the behavior heat and the predicted behavior heat.
In one embodiment of the invention, the smoothness absolute error is used to characterize the sum of the prediction errors of all selectable cue points, wherein the prediction error of a single selectable cue point may be the difference between the predicted behavior heat and the behavior heat. And the smoothness relative error is used for representing the sum of the prediction errors of all the selectable cue points after the prediction errors of the behavior heat between the adjacent selectable cue points are mutually offset.
Specifically, the differences between the prediction errors of adjacent selectable cue points in the smoothness relative error may cancel each other out in the calculation of the total error, and in order to make the differences between the prediction errors of adjacent selectable cue points in the smoothness absolute error not cancel out in the calculation of the total error, the differences between the prediction errors of every two selectable cue points may be calculated by taking the absolute value of the differences and then summing the absolute values.
Thus, in yet another embodiment of the invention, smoothness at time tAbsolute error M t Can be expressed as:
Figure BDA0003691582070000071
wherein beta is a preset adjusting parameter which can be 0.1 to 0.2; e.g. of a cylinder t Indicating the prediction error at time t, e t =x t -y t
Smoothness relative error E at time t t Can be expressed as:
E t =βe t +β(1-β)e t-1 +β(1-β) 2 e t-2 +…+β(1-β) t-1 e 1
i.e. E t =βe t +(1-β)E t-1 ;M t =βe t+1 +(1-β)M t-1
Wherein t is a natural number greater than 1; y is 1 =x 1 ;y 2 =x 1 ;e 1 =0;E 1 =0。
Step 204: determining the smoothness of the heat change according to the smoothness relative error and the smoothness absolute error.
In one embodiment of the invention, the smoothness of the heat change may be determined based on a proportional value between an absolute value of an absolute error of the smoothness and a relative error of the smoothness.
I.e. the heat change smoothness a at time t t Can be expressed as:
Figure BDA0003691582070000081
ratio value a t The larger the absolute error of the smoothness is relative to the relative error of the smoothness, the larger the degree of mutual cancellation of the prediction errors between the selectable cue points is, and therefore, the smoother the heat change between the selectable cue points is, i.e., the smoothness of the heat change is larger as a whole.
Step 30: and determining a target cue point from the selectable cue points according to the heat degree change smoothness.
In an embodiment of the present invention, the number of the selectable cue points is multiple, and in order to not interrupt the immersive viewing experience of the user, the selectable cue points with small smoothness of the heat change may be selected as the target cue points, that is, when the user has a change in the interaction behavior pattern, the prompt is timely performed, so that the attention of the user can be attracted, and the occurrence probability of the interaction is improved.
Thus, step 30 further comprises: step 301: determining a difference in the activity heat between the selectable cue points.
In one embodiment of the invention, besides considering the change of the interactive interest of the user represented by the smoothness of the heat change, so as to avoid interrupting the immersive experience of the user due to reminding, the interactive behavior trend of most users can be considered, namely, when most users perform interactive behaviors, the users are prompted to perform the interactive behaviors, so that the users are prompted to follow the general psychology to perform the interactive behaviors.
Therefore, whether the difference of the behavior heat degrees corresponding to the selectable prompt points is large or not can be determined, namely whether a selectable time point with stronger interaction atmosphere exists or not and at which most users perform interaction behaviors is determined, and if yes, reminding is performed at the time point.
Step 302: when the difference is smaller than a first threshold value, the target cue point is determined from the selectable cue points according to the heat degree change smoothness.
In an embodiment of the invention, when the difference is smaller than the first threshold, it indicates that the behavior heat of the selectable prompt point is relatively close, that is, the interaction interestingness corresponding to the selectable prompt point is similar, and there is no time point when the mutual atmosphere is relatively strong, which can prompt the user, so that the user can select from the behavior heat according to the behavior heat change smoothness, thereby avoiding the interference on the immersive watching experience of the user. Specifically, after the smoothness of the heat change is arranged in an ascending order, the selectable cue point of the preset bit before arrangement may be determined as the target cue point. Optionally, the selectable cue point with the smallest degree of smoothness of the heat variation can be selected as the target cue point.
Thus, in one embodiment of the present invention, step 302 further comprises:
step 3021: and when the difference value is smaller than the first threshold value, arranging the selectable cue points in an ascending order of the heat change smoothness, and determining the selectable cue points of preset bits before arrangement as the target cue points.
In one embodiment of the invention, after all the selectable cue points are arranged according to the ascending order of the illumination heat degree change smoothness, the selectable cue points of the front preset bits arranged in the ascending order are determined as the target cue points, so that the interference on the immersive watching experience of the user is avoided. Optionally, the selectable cue point with the smallest heat variation smoothness may be determined as the target cue point.
Step 303: and when the difference is larger than or equal to a second threshold value, determining the target prompt point from the selectable prompt points according to the behavior heat of the time point.
In one embodiment of the invention, the second threshold may be the same as the first threshold. When the difference is larger than or equal to the second threshold, the behavior heat degree difference between the selectable prompt points is large, namely, the interaction interestingness corresponding to some selectable prompt points is higher than that of other selectable prompt points, and the selectable prompt points with higher interaction interestingness can reflect a climax atmosphere of the user participating in the interaction. Therefore, a selectable time point with the maximum interaction interest of the user can be selected as a target prompt point, and the user is prompted to interact through the interaction climax atmosphere of most users.
Thus, in yet another embodiment of the present invention, step 303 further comprises:
step 3031: when the difference value is larger than the second threshold value, determining the selectable prompt point with the maximum behavior heat degree as a heat degree central point.
In one embodiment of the invention, the selectable cue point with the greatest degree of activity represents the climax of the interactive activity of most users, and therefore can be taken as the center point of the degree of activity.
Step 3032: and determining the time point adjacent to the heat central point as the target prompt point.
In one embodiment of the invention, the heat center point represents the center of the climax of the user's participation in the interactive activity, so that the user can be prompted at a time point near the center of the climax to prompt the user that most other users are about to or are interacting, and the user is prompted to participate in the interactive climax by the crowd psychology.
Step 40: and inserting prompt information at the target prompt point to obtain a processed video.
In an embodiment of the invention, the prompt information is inserted into the video frame corresponding to the target prompt point to obtain the processed video. Wherein the number of prompt messages, prompt types, priorities, etc. are first determined. The number of the prompt messages is generally not suitable to be too large, 1-3 types of prompt messages can be set, the trigger types comprise comments, praise, coin insertion and sharing, and the priority can be determined according to business requirements.
Specifically, the determination process of the prompt type may be as follows: determining time points and behavior contents corresponding to various types of behaviors in the user behavior data, wherein the behavior contents can comprise comments and text contents of barrage, and can also be video information, such as video tags, video lines and the like. And finally, determining the corresponding behavior type as a prompt type according to the behavior content on the target prompt point.
In another embodiment of the present invention, natural language processing and semantic analysis may be further performed on the user behavior data corresponding to the target prompt point to obtain a semantic analysis result, where the semantic analysis result may include, for example, a bullet screen and comment semantics corresponding to the target prompt point; and when the semantics comprise the semantic information corresponding to the preset interaction type, such as praise, forwarding/sharing, one-key triple connection and the like, determining the interaction type corresponding to the included semantic information as the prompt type of the prompt information.
Step 50: and displaying the processed video.
In one embodiment of the invention, an interaction control or identifier may be displayed at the target cue point in the processed video, thereby prompting the user to interact there.
Specifically, when the same behavior is triggered, the triggered prompt can not be repeated in the video. When the prompt contact is triggered, the icon needing to be prompted displays a prompt dynamic effect which can be GIF, animation or sound and the like. The prompt action can be a fixed duration, and can also be adjusted according to the data quantity corresponding to the contact. If the difference between the data quantity and the average data quantity of all the time points is larger, the time length for prompting the point is longer. If the original prompt effect duration is T, the corrected duration T Repair the = (MAX (x) -AVER (x))/AVER (x) × (1+T); wherein x is the data number corresponding to one time point, MAX (x) is the maximum value of the average values of the data numbers corresponding to all time points, and AVER (x) is the average value of the data numbers corresponding to all time points.
In yet another embodiment of the present invention, the process of video hinting can be referred to FIG. 2.
As shown in fig. 2, step a: and determining the optimal prompt point according to data such as user comments, barrage and the like.
According to a fixed time interval, user comment and barrage quantity data of each playing progress time point of the video are obtained, optionally, user behavior data such as sharing, forwarding, and barrage can be obtained, but the comment and the barrage are representative, and therefore the two types of behavior data are taken as an example. The number of the two types of behaviors, namely the bullet screen and the comment, can be calculated in a combined mode or in a separated mode. The corresponding relationship between the time point and the data quantity obtained by combining and calculating the behavior data quantities of the barrage and the comments can refer to fig. 3.
Taking the data quantity in the figure 3 as behavior heat, sequencing the behavior heat from high to low, respectively acquiring the first n data and corresponding time points, and when n is 3, acquiring the first 3 data and corresponding time points of the following data, wherein the data are respectively as follows:
01.
Then, respectively determining corresponding heat change smoothness for time points n before the behavior heat ranking, wherein the calculation process of the heat change smoothness can be as follows:
firstly, numbering time sequences formed by all time points according to a time sequence to obtain a time sequence t, wherein t is a natural number.
Setting the total number of the barrage and the comments as x, and taking the x as the actual behavior data volume corresponding to the time point;
setting an initial smoothing index as a;
if the predicted behavior heat is y, then y t =ax t +(1-a)y t-1
Setting the initial parameter value as beta, and the value range of the beta is (0.1-0.2);
the prediction error of the smoothness of the heat change at time t is e t Then e t =x t -y t And taking a weighted average value of the prediction errors of all the time points t to obtain:
absolute error M of smoothness at time t t Can be expressed as
Figure BDA0003691582070000111
Smoothness relative error E at time t t Can be expressed as:
E t =βe t +β(1-β)e t-1 +β(1-β) 2 e t-2 +…+β(1-β) t-1 e 1
i.e. E t =βe t +(1-β)E t-1 ;M t =βe t+1 +(1-β)M t-1
Wherein t is a natural number greater than 1; y is 1 =x 1 ;y 2 =x 1 ;e 1 =0;E 1 =0。
I.e. the heat change smoothness a at time t t Can be expressed as:

TABLE 1
As with reference to table 1, ranked by data size in the order t10> t9> t6, the size relationship between the corresponding data quantities is: 38>37>33, the difference of the data amounts between the three <10% is illustrated here with 10% as a threshold value, and the smoothness of the heat change corresponding to each of the three is 0.9,0.1,0.1
There are two minimum values, respectively: t9 corresponds to 0.1; t6 corresponds to 0.1, so that t9 is determined as the best cue point, i.e., in left-to-right order.
Alternatively, the time point at which the data amount of the time point adjacent to the time point is maximum may be determined as the optimal cue point.
Such as: adjacent points of t10 are t9 and t11, respectively, and the corresponding data quantities are 37 and 27, respectively;
adjacent points of t9 are t8 and t10, respectively, and the corresponding data quantity is 17 and 38;
the adjacent points of t6 are t5 and t7 respectively, and the corresponding data quantity is 27,9 respectively;
it can be seen that t9 is the best cue point if the number of data of the neighboring point of t9 is the largest and 38.
In addition to the above method, the time point corresponding to the maximum data amount may be directly used as the optimum cue point. Such as: t10.
It should be noted that there may be a plurality of optimal cue points, or there may be only one optimal cue point. Depending on how many different prompts need to be provided to the user.
And B: and determining the prompt content and the prompt type corresponding to the optimal prompt point.
In step a, three optimal contacts, t9, t10, and t6, are identified.
And inserting prompt information into the video frame corresponding to the target prompt point to obtain a processed video. Wherein, firstly, the number, the prompt type, the priority and the like of the prompt messages are determined. The number of the prompt messages is not suitable for being too large generally, the prompt messages can be set to be 1-3 types, the triggering types comprise comments, praise, coin insertion and sharing, and the priority can be determined according to business requirements.
Specifically, the determination process of the prompt type may be as follows: determining time points and behavior contents corresponding to various types of behaviors in the user behavior data, wherein the behavior contents can comprise comments and text contents of barrage, and can also be video information, such as video tags, video lines and the like. And finally, determining the corresponding behavior type as a prompt type according to the behavior content on the target prompt point.
Natural language processing and semantic analysis can be further performed on the user behavior data corresponding to the target prompt point to obtain a semantic analysis result, and the semantic analysis result can include a bullet screen and comment semantics corresponding to the target prompt point; and when the semantics comprise the semantic information corresponding to the preset interaction type, such as praise, forwarding/sharing, one-key triple connection and the like, determining the interaction type corresponding to the included semantic information as the prompt type of the prompt information.
And C: and prompting at the target prompt point according to the prompt content and the prompt type.
An interaction control or identifier may be displayed at the target cue point in the processed video, thereby prompting the user to interact there. Wherein, the target cue point is the best cue point mentioned in the steps A and B.
Specifically, when the same behavior is triggered, the triggered prompt can not be repeated in the video. When the prompt contact is triggered, the icon needing to be prompted displays a prompt dynamic effect which can be GIF, animation or sound and the like. The prompt action can be a fixed duration, and can also be adjusted according to the data quantity corresponding to the contact. If the difference between the data quantity and the average data quantity of all the time points is larger, the prompting time length for the point is longer. If the original prompt effect duration is T, the corrected duration T Repair the = (MAX (x) -AVER (x))/AVER (x) × (1+T); wherein x is the data quantity corresponding to one time point, MAX (x) is the maximum value of the average values of the data quantities corresponding to all the time points, and AVER (x) is the average value of the data quantities corresponding to all the time points.
