Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

First embodiment

Fig. 1 is a flowchart of a page display method in a first embodiment of the present application, where the technical solution of the present embodiment is applicable to a case of deep conversion probability estimation according to a history display page of a first type of display conversion and a history display page of a second type of display conversion at the same time, where the method may be executed by a page display device, and the device may be implemented by software and/or hardware and may be generally integrated in a server, and the method of the present embodiment specifically includes the following steps:

Step 110, obtaining a plurality of alternative display pages, wherein the display pages are associated with a first type of display conversion and at least one second type of display conversion, and the second type of display conversion probability is higher than the first type of display conversion probability.

The conversion display probability of the first type of conversion display is the conversion display probability of the first type of conversion display, and the conversion display probability of the second type of conversion display is the conversion display probability of the second type of conversion display.

The presentation page is a page provided by a client of the Internet platform and required to be presented to a user of the Internet platform.

The internet platform may be a platform for providing a certain internet service, and illustratively, the internet platform may be a search engine, a video website or forum, a social networking site, or the like, and the client of the internet platform may be a platform having a cooperative relationship with the internet platform and pushing information through the internet platform, and illustratively, the client of the internet platform may be a media platform, a cooperative merchant (offline or online), a software developer, or the like. The user of the internet platform may be a general user who accesses the internet platform to obtain the corresponding service.

The display page can be a page which needs to be displayed in an internet platform and comprises popularization information. The promotion information can be a media article which needs to be promoted by a media platform, one or more commodities which need to be promoted by a merchant, one or more application programs which need to be promoted by software development, and the like.

In a specific application scenario of this embodiment, a user of an internet platform accesses the internet platform and satisfies a page pushing condition (for example, the access duration exceeds a set threshold, or clicks to view a certain set page, etc.), then the user may trigger to obtain multiple alternative presentation pages corresponding to a certain client of the internet platform, where different alternative presentation pages respectively carry different popularization information.

In this embodiment, first, a plurality of alternative presentation pages provided by a client of an internet platform are acquired, the presentation pages are presented on the internet platform, a user of the internet platform may click on the presentation pages and perform a series of operations, such as information consultation, registration account number, and commodity purchase, the series of operations performed by the user are called presentation conversion, and are classified into two types, namely, the presentation page is associated with the first type of presentation conversion and at least one second type of presentation conversion according to the conversion degree, wherein the first type of presentation conversion represents a presentation conversion with a higher conversion degree, such as commodity purchase, and the second type of presentation conversion represents a presentation conversion with a lower conversion degree, such as information consultation or account number registration, and in general, the internet platform user may perform the first type of presentation conversion on the basis of the second type of presentation conversion, so that the second type of presentation conversion probability is higher than the first type of presentation conversion probability.

The method includes the steps that when an alternative showing page is a commodity advertisement page provided by an online merchant, a user clicks the showing page and performs account registration to serve as second-type showing conversion, and after account registration is completed, the user performs commodity purchase, and then successful commodity ordering operation serves as first-type showing conversion.

Optionally, the first type of presentation transformation is a deep presentation transformation, and the second type of presentation transformation is a shallow presentation transformation; deep presentation transformation the transformation is achieved after completion of at least one shallow presentation transformation.

In this optional embodiment, deep presentation conversion is defined into a first type of presentation conversion, where deep presentation conversion refers to conversion with higher conversion degree, for example, an internet platform user completes a commodity ordering operation by clicking a commodity advertisement page, shallow presentation conversion refers to conversion with lower conversion degree, for example, an internet platform user performs commodity information consultation or browses a commodity webpage for more than 5 minutes by clicking a commodity advertisement page, and in general, a user performs ordering after consulting commodity information or continuously browses for a certain period of time, that is, deep presentation conversion is implemented after at least one shallow presentation conversion is completed.

or alternatively, the process may be performed,

In the optional embodiment, specific examples of deep display conversion and shallow display conversion are provided, and when the display page is an advertisement page of the commodity, the deep display conversion is used for forming a purchase order of the commodity displayed in the display page, and the shallow display conversion is used for forming a purchase consultation of the commodity displayed in the display page; or when the display page is an application program promotion page, the deep display is converted into activating the application program displayed in the display page, and the shallow display is converted into downloading the application program displayed in the display page.

And step 120, predicting the first type display conversion probability of each alternative display page according to the first type history display page matched with the first type display conversion and the second type history display page matched with the second type display conversion.

The first type history display page matched with the first type display conversion is a page subjected to the first type display conversion, for example, a display page for forming a purchase order of the commodity displayed in the display page; the second type history presentation page matched with the second type presentation conversion is a page in which the second type presentation conversion occurs, for example, a presentation page in which purchase consultation of the goods presented in the presentation page is formed.

In this embodiment, since the client of the internet platform cooperates with the internet platform to display the number of deep display conversions, that is, to increase the number of first-class display conversions, for example, when the client of the internet platform is an online merchant, the client's final purpose is to increase the number of merchandise orders, the internet platform predicts the first display conversion probabilities of the plurality of candidate display pages in turn according to the first-class historical display pages and the second-class historical display pages, so as to determine whether to display the candidate display pages according to the first display conversion probabilities. For example, the first presentation conversion probability may be determined according to a matching result by matching feature information extracted from the alternative presentation page with feature information extracted from the first type of history presentation page and the second type of presentation page.

Optionally, predicting the first class conversion probability of each candidate presentation page according to the first class history presentation page matched with the first class presentation conversion and the second class history presentation page matched with the second class presentation conversion may be:

predicting the first type of display conversion probability of each candidate display page according to the matching result;

In this optional embodiment, a specific manner of predicting a first class conversion probability of each alternative presentation page according to a first class history presentation page and a second class history presentation page is provided, and the specific process is as follows:

firstly, a display feature set corresponding to each alternative display page is obtained, wherein the display feature set can be a feature vector, the feature vector contains the features of the current alternative display page and the features of the current user, for example, the display feature set can be (commodity category: mother and infant articles, commodity name: infant food, user age: 29, user gender: girl, user identity portrait: novice mom), and of course, the feature information in the display feature set can be replaced by an information identifier, for example, the sex is male, the sex is female, and the like.

Secondly, the display feature sets are respectively matched with a common display conversion feature set and a personalized display conversion feature set, wherein the common display conversion feature set is extracted from a first type of history display page and a second type of history display page, contains all feature information contained in the two types of history display pages, and can be extracted from one of the first type of history display pages, for example: (commodity category: outdoor supplies, commodity name: outdoor jacket, user age: 30, user gender: man, user identity image: white collar), and all feature sets extracted from all first type history display pages are formed into a feature set 1, and similarly, all feature sets extracted from all second type history display pages are formed into a feature set 2, and then the feature set 1 and the feature set 2 are jointly formed into a common display conversion feature set, wherein the personality display conversion feature set is feature information extracted from only the first type history display pages, and in the above example, all feature sets extracted from all first type history display pages are formed into a feature set 1, namely the personality display conversion feature set.

Alternatively, the feature sets in the set 1 and the set 2 may be clustered respectively to obtain multiple categories, and then the similarity between the feature set and the common display feature set and the similarity between the feature set and the individual display feature set may be calculated according to the similarity between the feature set and each category in the set 1 and the set 2, and specifically, the average value or the maximum value of the similarity between the feature set and each category in the set 1 may be obtained and used as the similarity between the feature set and the common display feature set; and acquiring the average value or the maximum value of the similarity between the display feature set and each category in the set 2, and taking the average value or the maximum value as the similarity between the display feature set and the individual display feature set.

Finally, the display feature sets corresponding to the alternative display pages are respectively matched with the common display conversion feature set and the individual display conversion feature set, the similarity between the display feature set and the common display feature set and the similarity between the display feature set and the individual display feature set can be calculated respectively, finally, the two similarity values are weighted and summed, and finally, the first type display conversion probability is obtained.

For example, the similarity between the display feature set and the common display feature set is 60%, the similarity between the display feature set and the individual display feature set is 45%, and further, the two similarities are weighted and summed to obtain the first type of display conversion probability, for example, if the weights of the common display feature set and the individual display feature set are set to be the same, the method can be according to the formula: 60% +45% + 50%, the first class calculated exhibits a probability of conversion.

Of course, it will be understood by those skilled in the art that the weights of the common display feature set and the individual display feature set may be determined according to the actual situation (for example, the number ratio of the first type of history display pages to the second type of history display pages), which is not limited in this embodiment.

And 130, acquiring at least one target page from a plurality of alternative display pages according to the prediction result, and displaying the at least one target page.

In this embodiment, according to the obtained first type of presentation conversion probability, at least one target page is obtained from a plurality of candidate presentation pages and presented, and specifically, according to a set presentation conversion probability threshold, the predicted candidate presentation page with the first type of presentation conversion probability higher than the presentation conversion probability threshold may be presented, for example, the presentation conversion probability threshold is set to be 45%; or after the alternative presentation pages with the first class presentation conversion probability higher than the presentation conversion probability threshold are acquired, the acquired alternative presentation pages are ordered according to the order of the first class presentation conversion probability from high to low, and a set number (for example, 3 or 5 or the like) of alternative presentation pages are acquired according to the order of the ordering result from high to low to be presented.

According to the technical scheme, the first type display conversion probability of each alternative display page is predicted according to the first type history display page matched with the first type display conversion and the second type history display page matched with the second type display conversion, and finally at least one display page is selected from the plurality of alternative display pages according to the prediction result to display, so that the prediction of the first type display conversion probability according to the first type history display page and the second type history display page is realized, and the problem that the prediction of the first type display conversion probability is inaccurate under the condition that the first type display conversion sample is insufficient is solved.

Second embodiment

Fig. 2a is a flowchart of a page showing method in a second embodiment of the present application, where the present embodiment is further refined on the basis of the foregoing embodiment, and specific steps of predicting a first class conversion probability of each alternative showing page and specific steps before obtaining a plurality of alternative showing pages are provided according to a first class history showing page matched with a first class showing conversion and a second class history showing page matched with a second class showing conversion.

The first type of the positive sample is composed of a first type of history display page and a user generating first type of display conversion on the first type of history display page, for example, the first type of the positive sample comprises a display page forming a purchase order of goods displayed in the display page and a user corresponding to the purchase order, wherein the user can be a user ID; the second positive sample is composed of a second type history display page and users generating second type display conversion on the second type history display page, for example, the second positive sample comprises display pages forming purchase consultation of the commodities displayed in the display pages and users corresponding to the purchase consultation.

In this embodiment, a first type positive sample and a second type positive sample are respectively configured by using a first type history display page and a second type history display page, specifically, the first type positive sample is formed by the first type history display page and a user generating first type display conversion matched with the first type history display page, and the second type positive sample is formed by the second type history display page and a user generating second type display conversion matched with the second type history display page.

Step 220, generating a sample feature set corresponding to each first type positive sample and each second type positive sample.

The sample feature set is a set of feature information extracted from the first type or the second type of positive samples, and may be a feature vector with a set format.

In this embodiment, sample feature sets corresponding to each first type of positive sample and each second type of positive sample are respectively generated, and a sample feature set is formed by combining the page feature of the first type of history display page and the user feature, where the sample feature set is specifically obtained, and the finally formed sample feature set is (commodity type: outdoor article, commodity name: outdoor jacket, user age: 30, user sex: male, user identity: white collar). The generation process of the sample feature set corresponding to the second type of positive sample is the same as the generation process of the sample feature set corresponding to the first type of positive sample, and will not be further described herein.

The multi-task learning model is designed for the condition that training samples are insufficient, and can be used for alleviating the problem of data sparseness by using useful information of other related learning tasks. In this embodiment, the multitasking model may simultaneously estimate the first type of presentation conversion probability by using the first type of history presentation page and the second type of history presentation page under the condition that the first type of history presentation page has insufficient data.

In this embodiment, the sample feature set obtained in step 220 is input to the multi-task learning model for training to optimize parameters in the multi-task learning model, and finally, the first presentation transformation probability prediction model is obtained. The first display conversion probability prediction model comprises a prediction task of a first type display conversion probability and at least one prediction task of a second type display conversion probability, and the prediction task is used for predicting the first type display conversion probability and the second type display conversion probability respectively.

the first class presentation conversion sub-network is obtained by independent training by using a sample feature set corresponding to the first class positive sample and is used for outputting a prediction result of the first class presentation conversion probability;

and the second class presentation conversion sub-network is obtained by independent training by using a sample feature set corresponding to the second class positive sample and is used for outputting a prediction result of the second class presentation conversion probability.

In this optional embodiment, a specific structure of a first type of presentation transformation probability prediction model is provided, as shown in fig. 2b, including a shared hidden layer connected to an input end, a first type of presentation transformation sub-network respectively connected to the shared hidden layer, and at least one second type of presentation transformation sub-network; the output end of the first-class presentation conversion sub-network is the output end of the first-class presentation conversion probability prediction model.

The shared hidden layer is obtained by training sample feature sets corresponding to the first type positive samples and the second type positive samples together, namely, parameters in the shared hidden layer are optimized through the sample feature sets corresponding to the first type positive samples and the second type positive samples. The first type of presentation conversion sub-network is obtained through first type of positive sample training, and can predict first type of presentation conversion probability according to the input presentation characteristic set. The second-class presentation conversion sub-network is obtained through second-class positive sample training, and can predict second-class presentation conversion probability according to the input presentation characteristic set.

Step 240, obtaining a plurality of alternative display pages, wherein the display pages are associated with a first type of display conversion and at least one second type of display conversion, and the display conversion probability of the second type of display conversion is higher than that of the first type of display conversion.

Step 250, obtaining display feature sets respectively corresponding to the candidate display pages.

In this embodiment, a display feature set corresponding to each candidate display page is obtained, where the display feature set may be a feature vector, and the feature vector includes features of the current candidate display page and features of the current user.

Optionally, the display feature set or the sample feature set is a discrete value feature set;

In this optional embodiment, the above-mentioned display feature set is a set formed by feature information of each display page, and the sample feature set is a set formed by feature information of each first type of history display page and each second type of history display page, so that the sample feature set is a discrete value feature set. Illustratively, discretizing the age information of the user in the plurality of sample feature sets yields discrete value features of the ages, for example, (0 years, 10 years) set to 1, (10 years, 20 years) set to 2, (20 years, 30 years) set to 3, and so on. Through the discretization process described above, much information is actually lost because all age characteristics (20 years, 30 years) use 2 as a discretization result, in order to compensate for the discretization loss described above in the model, because the input discrete value characteristic set can be converted into a continuous value characteristic set at the shared hidden layer.

Optionally, presenting the feature set or the sample feature set includes:

at least one page feature matching the presentation page, and at least one user feature corresponding to a presentation user of the presentation page.

260, respectively inputting each display feature set into a pre-trained first-class display conversion probability prediction model, and predicting the first-class display conversion probability of each alternative display page;

the first type of presentation conversion probability prediction model is obtained by training positive samples constructed by the first type of history presentation pages and the second type of history presentation pages.
