Technical Field
The disclosure relates to the technical field of data processing, and in particular relates to a media information quality prediction method, a device, electronic equipment and a storage medium.
Background
The media information may include information distributed to the public at the platform, and may include video information or image information in particular. Before the media information is put in, the method has important significance in predicting the put quality of the media information. For example: under the condition that the medium information is the advertisement material, the recall and the delivery of the advertisement material with high quality can be performed by predicting the delivery quality of the advertisement material, thereby being beneficial to accurately delivering the advertisement material and improving the conversion efficiency of the advertisement material.
In the related art, in the case that the user side information cannot be obtained before the media information is delivered, the delivery quality of the media information can be predicted through the content information of the media information. For example: the quality of the media information delivery can be predicted by whether the picture is clear/contains characters/whether music/intonation is fast or slow, etc.
However, the quality of the media information in the delivery link is not only related to the content information of the media information itself, for example: factors such as industry difference and time change have great influence on data such as click rate and/or conversion rate of media information. Accordingly, in the related art, the quality of delivery of the medium information is predicted only by the content information of the medium information itself, which results in a lower accuracy of prediction of the quality of delivery of the medium information.

Detailed Description
In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
It should be further noted that, the user information (including, but not limited to, user equipment information, user personal information, etc.) and the data (including, but not limited to, data for presentation, analyzed data, etc.) related to the present disclosure are information and data authorized by the user or sufficiently authorized by each party.
In one embodiment, as shown in fig. 1, a method for predicting the quality of media information is provided, where this embodiment is applied to a terminal for illustration, it is understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and implemented through interaction between the terminal and the server. In this embodiment, the method includes the steps of:
in step 102, historical data information of the media information to be predicted is obtained, where the historical data information includes first delivery data of the media information to be predicted within a preset time range, at least one associated media information corresponding to the same media information publisher as the media information to be predicted, and/or second delivery data of each associated media information within the preset time range.
In the embodiment of the disclosure, the media information to be predicted is media information of the quality to be predicted. The media information base may store media information released by each media information publisher and relevant release data released by each media information history, and in the case where the media information is an advertisement material, the media information publisher may be an advertiser releasing the advertisement material. By way of example, the delivery data may include data capable of characterizing the delivery quality of the media information, including, but not limited to, information such as the number of clicks, the number of exposures, the number of conversions, or data information determined by at least two of the number of clicks, the number of exposures, the number of conversions, etc., such as: the ratio determined by the conversion number to the exposure number can be identified as ctcvr. The embodiment of the disclosure does not specifically limit the delivery data, and can be set by a user according to a predicted requirement, and the embodiment of the disclosure is described below by taking a ratio ctcvr of the delivery data as a conversion number to an exposure number as an example, and when the delivery data is the ratio of the conversion number to the exposure number, the higher the ratio is, the better the delivery quality of the medium information is represented.
After determining the media information to be predicted, historical data information of the media information to be predicted can be obtained from a media information base, wherein the historical data information can comprise first delivery data generated in a preset time range, at least one associated media information corresponding to the same media information publisher of the media information to be predicted, and/or second delivery data generated in the preset time range by each associated media information in the historical delivery process of the media information to be predicted.
The preset time range is a preset time range, and the specific value can be determined by a user according to the predicted requirement. For example: the time range can be set to be within one week, the corresponding delivery data of the media information to be predicted within one week can be obtained from the media information base, and the delivery data (ctcvr 1, ctcvr2, ctcvr3, ctcvr, ctcvr5, ctcvr, ctcvr 7) of the media information to be predicted within one week can be obtained assuming that the delivery data is a ratio ctcvr of conversion number to exposure number. And the method can also acquire at least one piece of other media information released by the media information publisher from the media information base as the associated media information of the media information to be predicted according to the media information publisher corresponding to the media information to be predicted, and acquire the second release data of each associated media information in a week from the media information base.
In step 104, quality prediction is performed according to the media information to be predicted and the historical data information of the media information to be predicted, so as to obtain predicted delivery data of the media information to be predicted; wherein the delivery data includes data characterizing the quality of delivery of the media information.
In the embodiment of the disclosure, after obtaining the media information to be predicted and the historical data information of the media information to be predicted, quality prediction may be performed according to the media information to be predicted and the historical data information of the media information to be predicted, so as to obtain predicted delivery data of the media information to be predicted. For example: the first predicted delivery data of the medium information to be predicted may be determined in combination with the content included in the medium information to be predicted, the second predicted delivery data of the medium information to be predicted may be determined according to the history data information (the second predicted delivery data may be determined according to the first delivery data and/or the second delivery data, for example, a mean value of the first delivery data and/or the second delivery data may be used as the second predicted delivery data), and the first predicted delivery data and the second predicted delivery data may be weighted and summed to obtain the predicted delivery data of the medium information to be predicted.
Or the predicted delivery data of the medium information to be predicted can be obtained by performing prediction processing on the medium information to be predicted and the historical data information of the medium information to be predicted through a pre-trained neural network.
After obtaining the predicted delivery data of the media information to be predicted, the media information to be predicted can be recalled and link ordered according to the predicted delivery data, for example: and under the condition that the predicted delivery data is larger than the delivery threshold value, the media information to be predicted is recalled, and the position sequence of the media information to be predicted in the recall link is determined according to the predicted delivery data, so that the high-quality media information can enter the recall link, and the benefits of a media information publisher and a platform are improved.
According to the embodiment of the disclosure, the predicted delivery data of the medium information to be predicted is obtained by acquiring the historical data information of the medium information to be predicted and carrying out quality prediction according to the medium information to be predicted and the historical data information of the medium information to be predicted. The historical data information comprises first throwing data of the media information to be predicted in a preset time range, at least one associated media information corresponding to the same media information publisher of the media information to be predicted, and/or second throwing data of each associated media information in the preset time range. According to the media information quality prediction method provided by the embodiment of the disclosure, under the condition that the user side information cannot be obtained, the release quality of the media information to be predicted can be predicted by introducing the historical data information of the media information to be predicted, and as the historical data information can reflect potential favorites of most users to a certain extent, the release quality of the media information to be predicted is predicted by combining the historical data information of the media information to be predicted, and the prediction precision of the release quality can be improved.
In an exemplary embodiment, quality prediction according to the media information to be predicted and the historical data information of the media information to be predicted may be implemented through a quality prediction network, so as to obtain predicted delivery data of the media information to be predicted, as shown in fig. 2, where the quality prediction network includes a feature extraction network and a prediction network.
As shown in fig. 3, the quality prediction is implemented by the quality prediction network according to the media information to be predicted and the historical data information of the media information to be predicted, specifically, the method may be implemented by the following steps:
In step 302, feature extraction is performed on the media information to be predicted and the historical data information of the media information to be predicted through a feature extraction network, so as to obtain material features corresponding to the media information to be predicted;
in step 304, the material characteristics are predicted by the prediction network, so as to obtain predicted delivery data of the media information to be predicted.
In an embodiment of the present disclosure, the quality prediction network includes a feature extraction network and a prediction network. The feature extraction network is used for extracting material features, and the prediction network is used for predicting according to the material features to obtain predicted delivery data. After the media information to be predicted and the historical data information corresponding to the media information to be predicted are obtained, the media information to be predicted and the historical data information of the media information to be predicted can be input into a feature extraction network in a quality prediction network as input information to perform feature extraction, and after the material features of the media information to be predicted are obtained, the material features of the media information to be predicted are input into the prediction network as input information to perform prediction processing, so that predicted delivery data of the media information to be predicted are obtained.
For example: the historical data information comprises a plurality of associated media information of the same advertiser corresponding to the media information to be predicted, the media information to be predicted and the associated media information can be input into the feature extraction network to perform feature extraction to obtain material features of the media information to be predicted, and the material features are input into the prediction network to perform prediction processing to obtain predicted delivery data of the media information to be predicted.
According to the media information quality prediction method provided by the embodiment of the disclosure, the prediction of the delivery quality of the media information to be predicted according to the media information to be predicted and the historical data information of the media information to be predicted can be realized through the quality prediction network, namely, the characteristics of the historical data information are integrated into the characteristics of the media information to be predicted, so that the preference of a user is known, and the prediction efficiency and the prediction precision of the delivery quality can be improved.
In an exemplary embodiment, before implementing quality prediction according to the media information to be predicted and the historical data information of the media information to be predicted through the quality prediction network to obtain the predicted delivery data of the media information to be predicted, the method may further include: and training the quality prediction network by adopting a pre-constructed training set, wherein the training set comprises a plurality of sample groups, and the sample groups comprise sample medium information, historical data information of the sample medium information and labeling put-in data of the sample medium information. Referring to fig. 4, training a quality prediction network using a pre-constructed training set may be specifically implemented by:
in step 402, a quality prediction network predicts sample media information and historical data information of the sample media information to obtain predicted delivery data corresponding to the sample media information;
In step 404, according to the predicted delivery data corresponding to the sample media information and the labeling delivery data of the sample media information, determining a predicted loss of the quality prediction network;
In step 406, the quality prediction network is trained based on the predicted loss.
In the embodiment of the disclosure, a sample group can be constructed according to the medium information in the medium information base as sample medium information, the history data information of the medium information as the history data information of the sample medium information, and the current delivery data of the medium information as the label delivery data of the sample medium information, a training set can be constructed according to the sample medium information, the history data information of the sample medium information, and the label delivery data of the sample medium information, and a training set can be constructed according to a plurality of sample groups, and a network can be predicted according to the training quality of the training set.
For example, the sample advertisement data and the historical data information of the sample advertisement data can be used as input information to be input into a quality prediction network for quality prediction, and the output of the quality prediction network is the predicted delivery data corresponding to the sample medium information. After the predicted delivery data of the sample medium information is obtained, the predicted loss of the quality prediction network can be determined according to the predicted delivery data of the sample medium information and the marked delivery data of the sample medium information. The embodiment of the present disclosure does not specifically limit the specific manner of determining the predicted loss, and virtually any loss calculation manner is applicable to the embodiment of the present disclosure, for example: the loss calculation modes such as MSE (Mean Square Error ) and MAE (Mean Absolute Error, absolute error).
It should be noted that, in the embodiment of the present disclosure, the network structure of the predicted network is not specifically limited, for example: the predictive network may be a DNN (Deep Neural Networks, deep neural network) network comprising multiple fully connected layers and relu activation functions, etc. modules.
After determining the predicted loss of the quality prediction network, the quality prediction network may be trained based on the predicted loss. For example, in the case where the predicted loss does not meet the training requirement (e.g., the predicted loss is greater than a preset loss threshold), the network parameters of the quality prediction network may be adjusted according to the predicted loss, including adjusting the parameters of the feature extraction network and adjusting the parameters of the quality prediction network, until the predicted loss of the quality prediction network meets the training requirement (e.g., the predicted loss is less than or equal to the preset loss threshold), to obtain the trained quality prediction network.
According to the media information quality prediction method provided by the embodiment of the disclosure, the training set can be constructed according to the sample media information and the historical data information of the sample media information, and the quality prediction network is trained through the constructed training set, so that the prediction of the delivery quality of the media information to be predicted according to the media information to be predicted and the historical data information of the media information to be predicted can be realized through the quality prediction network, and the prediction efficiency and the prediction precision of the delivery quality can be improved.
In an exemplary embodiment, the historical data information includes first delivery data of the media information to be predicted within a preset time range, and the feature extraction network includes a first network and a second network. Referring to fig. 5, in step 302, feature extraction is performed on media information to be predicted and historical data information of the media information to be predicted through a feature extraction network, so as to obtain material features corresponding to the media information to be predicted, which may be specifically implemented by the following steps:

In step 504, vector conversion processing is performed on the first delivery data through the second network, so as to obtain a first vector representation;
In step 506, material characteristics of the media information to be predicted are obtained according to the first content characteristics and the first vector representation.
In the embodiment of the disclosure, referring to fig. 6, the historical data information includes first delivery data of the media information to be predicted within a preset time range, the feature extraction network includes a first network and a second network, where the first network is used for feature extraction of the network to be predicted to obtain a first content feature, and the second network is used for vector conversion processing of the first delivery data of the network to be predicted to obtain a first vector representation of the first delivery data.
In one example, the first network may include at least one of a first feature extraction module for extracting visual features of the media information, a second feature extraction module for extracting image text features of the media information, a third feature extraction module for extracting phonetic text features of the media information, and a fourth feature extraction module for extracting audio features of the media information.
The first feature extraction module, the second feature extraction module, the third feature extraction module, and the fourth feature extraction module may be pre-trained network modules. In the embodiment of the present disclosure, the network structures of the first feature extraction module, the second feature extraction module, the third feature extraction module, and the fourth feature extraction module are not limited, any network module capable of implementing the corresponding feature extraction function is suitable for use in the embodiment of the present disclosure, and for convenience of understanding, in the embodiment of the present disclosure, the first feature extraction module is a moco (Momentum Contrast for Unsupervised Visual Representation Learning, non-supervised visual representation learning based on momentum comparison) model, the second feature extraction module and the third feature extraction module are a Bert (Bidirectional Encoder Representations from Transformers, bi-directional coding representation based on a converter) model, and the fourth feature extraction module is a vggish model.
The first feature extraction module may employ different visual feature extraction strategies according to different types of media information. For example, for the media information of the picture type, the first feature extraction module may directly extract moco features of the picture as visual features of the media information; for the media information of the video type, the first feature extraction module may average moco features of the multi-frame image (for example, extract 8 frames) from the video, and then average moco features of the multi-frame image to obtain the visual features of the media information of the video type.
The second feature extraction module may also employ different visual feature extraction strategies according to different types of media information. For the media information of the picture type, text information appearing in the picture/video can be extracted by using methods such as OCR (Optical Character Recognition ) and the like, and then the image text characteristics in the text information are extracted; for the media information of the video type, extracting multiple frames of images (for example, extracting 8 frames) from the video, extracting text information for each frame of images, splicing the text information of the multiple frames of images, and extracting the image text characteristics of the spliced text information.
The third feature extraction module is similar to the second feature extraction module, and extracts the voice text features in the voice text information after extracting the voice text information in the video by using ASR (Automatic Speech Recognition, automatic voice recognition technology). The fourth feature extraction module may directly perform audio feature extraction on audio data in the video.
After the characteristics are extracted through the multiple items in the first characteristic extraction module, the second characteristic extraction module, the third characteristic extraction module and the fourth characteristic extraction module, the extracted multiple items of characteristics can be spliced to obtain the first content characteristics of the media information to be predicted.
The second network is used for vector conversion of the put data, the network structure of the second network is not limited in the embodiment of the disclosure, and any network structure capable of realizing vector expression is in the application range of the embodiment of the disclosure.
Illustratively, the second network may be modeled based on an anchor interpolation concept. The second network is used for vector conversion of the input data, taking the ratio ctcvr of the input data as a conversion number and an exposure number as an example, ctcvr is a random number within a value range of 0-1, and has infinite values, and the second network can convert the input data into a fixed-dimension expression through anchor point interpolation. By way of example, a plurality ctcvr of anchor points may be pre-designed, for example: 8 total ctcvr of [1e-7,1e-6,1e-5,1e-4,1e-3,1e-2,1e-1,1] were determined to be 8 anchors. For a plurality of ctcvr anchor points, taking the logarithm with the base of 10 to obtain the corresponding numerical value of each anchor point, taking the above 8 anchor points as an example, taking the logarithm with the base of 10 to obtain [ -7, -6, -5, -4, -3, -2, -1,0].
When the second network is constructed, a vector representation Emb i may be randomly initialized for each of the plurality of anchors, where Emb i represents a vector representation of an anchor with a value i, and the second network is constructed according to the vector representations Emb i of the plurality of anchors. For example, after the 8 anchor points are randomly initialized to be represented by vectors, [Emb-7,Emb-6,Emb-5,Emb-4,Emb-3,Emb-2,Emb-1,Emb0], may be obtained to construct a second network according to the 8 anchor points. And in the training process of the quality prediction network, vector representations of a plurality of anchor points of the second network are continuously adjusted until vector representations corresponding to the anchor points are obtained after the training is completed.
For the first delivery data, a logarithm based on 10 may be taken for the first delivery data to obtain a corresponding numerical value, two anchor points (assumed to be a first anchor point and a second anchor point) adjacent to the numerical value are determined, and the vector representations of the two adjacent anchor points are linearly combined to obtain a first vector representation of the first delivery data, and the specific process may refer to the following formula (1).
Wherein the Emb ctcvr is used for representing a first vector representation corresponding to the first delivery data,Vector representation for representing a first anchor point,/>Vector representation for representing the second anchor point ctcvr represents the first delivery data, ctcvr j-1 represents the delivery data corresponding to the first anchor point, and ctcvr j represents the delivery data corresponding to the second anchor point.
Taking the first delivery data as 0.005 as an example, the second network takes the logarithm based on 10 to obtain-2.30, and the obtained first vector represents the reference formula (2) because-2.30 is positioned between anchor points corresponding to the-3 value and the-2 value:
Emb -2.3=(-2-(-2.3))*Emb-3+(-2.3-(-3))*Emb-2 formula (2)
It should be noted that, the above-mentioned setting of 8 anchor points is only an example of the embodiment of the disclosure, in fact, N anchor points may be set, and the value of N may be set according to the prediction requirement. When first delivery data smaller than the corresponding minimum delivery data in the plurality of anchor points appears, the vector representation of the anchor point with the minimum corresponding delivery data can be used as the vector representation of the first delivery data; accordingly, when first delivery data larger than corresponding maximum delivery data among the plurality of anchor points occurs, the vector representation of the anchor point with the corresponding maximum delivery data may be used as the vector representation of the first delivery data. Taking the above 8 anchor points as an example, when the first delivery data is smaller than 1e-7, the vector representation corresponding to the anchor point (1 e-7) can be used as the vector representation of the first delivery data; or when the first delivery data is greater than 1, the vector representation corresponding to the anchor point (1) can be used as the vector representation of the first delivery data.
Therefore, the second network can realize vector representation of any one of the put data by using vector representations of a plurality of anchor points, the second network is lighter, and the prediction efficiency of the quality prediction network can be improved.
After the first content characteristics and the first vector representations are obtained, the first content characteristics and the first vector representations can be spliced to obtain the material characteristics of the media information to be predicted, and further, the material characteristics are predicted through a prediction network, so that the predicted delivery data of the media information to be predicted can be obtained.
