The mobile terminals involved in the embodiments of this application may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment (User Equipment, UE), mobile station (Mobile Station, MS), terminal device (terminal device), etc. For ease of description, the devices mentioned above are collectively referred to as mobile terminals.

The following describes the embodiments of the present application in detail.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a content pushing method disclosed in an embodiment of the present application. As shown in FIG. 1, the content pushing method includes the following steps.

101. The server acquires real-time user characteristics and real-time characteristic parameters of multiple user IDs corresponding to the target natural person identification ID, and generates real-time user characteristics of the target natural person identification ID based on the real-time user characteristics of the multiple user IDs, and the real-time characteristic parameters include the current Point in time.

In the embodiments of the present application, the server serves the client, and the content of the service includes providing resources to the client and storing client data. The server is a targeted service program, and the device running the server can be called a server. The server can establish connections with multiple clients at the same time, and can provide services to multiple clients at the same time. The services provided by the server for the client in the embodiments of the present application mainly include content push services. The content push service may include: an advertisement content push service. The advertisement content push service may include: browser content push service, application content push service, game content push service, etc. The server can include application server, browser server, game server, etc.

User ID can include any one or more of the following types: single sign on identity (SSOID), OpenID, integrated circuit card identity (ICCID), international mobile device identity (International Mobile) Equipment Identity, IMEI), telephone number (telephone, TEL), Globally Unique Identifier (GUID), etc. SSO is in multiple application systems. Users only need to log in once to access all mutually trusted application systems.

Among them, the natural person ID in the embodiment of this application corresponds to a natural person. This natural person may correspond to a mobile terminal (for example, a mobile phone), at least one phone number, at least one application account, at least one OpenID, one SSOID, at least one ICCID, and at least one IMEI. For example, if a natural person has a mobile phone, a phone number, and 5 application accounts, the IMEI, phone number, and 5 application accounts of the mobile phone are labeled with a natural person ID. The user behavior data corresponding to these 5 application accounts all belong to the user behavior data of this natural person ID. In this way, a real natural person can have many user IDs (for example, the IMEI of a mobile phone, a phone number, and 5 application accounts), but only one unique natural person ID is corresponding. The specific presentation form of the natural person ID can be a string of characters. The natural person ID can correspond to an identification of a mobile terminal. When the server pushes content to the natural person ID, it can push the content to the mobile terminal corresponding to the natural person ID without sending the pushed content to the application account separately, thereby improving the push efficiency.

The user characteristics of the user ID may include device characteristics, positioning characteristics, and application (APP) characteristics. Device characteristics may include the model of the device, the identification of the device, and so on. The positioning features may include global positioning system (Global Positioning System, GPS) positioning information, mobile location-based service (Location Based Service, LBS) location trajectory, etc. The application program characteristics may include the cumulative running time of the application program, the number of startup times of the application program, the usage frequency and times of the application program, and the usage of the application program function. Among them, the application function usage includes the types of advertisements that are paid attention to in the application, the application preference, etc.

Among them, the real-time user characteristics of the user ID are the user characteristics of the user ID collected at the current point in time.

The server can generate the real-time user characteristics of the target natural person identification ID based on the real-time user characteristics of multiple user IDs. For example, if there are 5 user IDs corresponding to the target natural person identification ID, the server can obtain 5 real-time user characteristics of these 5 user IDs, and the server can integrate the 5 real-time user characteristics of these 5 user IDs , Get the real-time user characteristics of the target natural person ID. Specifically, for example, if the 5 real-time user characteristics include: the advertisement A followed by the first APP, the login information of the second APP (not logged in), the login information of the third APP (not logged in), and the login information of the fourth APP ( Not logged in), the login information of the fifth APP (not logged in), then only one user feature (ad A followed by the first APP) among these 5 real-time user features is a useful feature, then the ads followed by the first APP A is the real-time user characteristic of the target natural person ID. Generally speaking, among the real-time user features of multiple user IDs at a point in time, there is generally only one user feature with at most one user ID as a useful feature. In some cases, the user may open multiple APPs at the same time. Among the real-time user characteristics of multiple user IDs, multiple user ID characteristics may be useful characteristics. In this case, multiple user ID characteristics need to be integrated. For another example, if 5 real-time user characteristics include: Advertisement A followed by the first APP, Advertisement B followed by the second APP, Advertisement C followed by the third APP, login information of the fourth APP (not logged in), and the fifth APP Login information (not logged in). If only 3 user characteristics (Ad A followed by the first APP, Ad B followed by the second APP, and Ad C followed by the third APP) of the 5 real-time user characteristics are useful features, then from these 3 user characteristics The types of Advertisement A, Advertisement B, and Advertisement C are determined in, if the types of Advertisement A, Advertisement B, and Advertisement C are the same, and they are all type XX advertisements, it can be determined that the real-time user characteristics of the natural person ID are type XX advertisements.

Optionally, before performing step 101, the following steps may be performed:

(11) The server obtains the correspondence between the natural person ID and the user ID;

(12) The server determines multiple user IDs corresponding to the target natural person ID according to the corresponding relationship between the natural person ID and the user ID.

In the embodiment of the present application, the corresponding relationship between the natural person ID and the user ID can be stored in the database of the server. The server can quickly determine multiple user IDs corresponding to the target natural person ID according to the correspondence between the natural person ID and the user ID.

Optionally, before performing step (11), the following steps can also be performed:

(21) The server obtains the historical behavior data of N user IDs reported by multiple clients, and calculates the similarity between the historical behavior data of N user IDs, where N is a positive integer;

(22) The server constructs a relationship pair between user IDs based on the similarity between the historical behavior data of N user IDs;

(23) The server constructs the corresponding relationship between the natural person ID and the user ID according to the relationship between the user IDs. In the corresponding relationship between the natural person ID and the user ID, one natural person ID corresponds to at least two user IDs.

In the embodiment of the present application, the historical behavior data may include: historical device characteristics, historical positioning characteristics, and historical application (Application, APP) characteristics of N user IDs. Historical device characteristics can include the model of the device, the identification of the device, and the usage habits of the device (for example, the backlight brightness of the device, the volume of the device, the holding posture of the device, the average use time of the device, the boot time of the device, and the Shutdown time, etc.). Historical positioning features may include global positioning system (Global Positioning System, GPS) positioning information, mobile location-based service (Location Based Service, LBS) location trajectory, etc. Historical application features can include application setting parameters (for example, application brightness, application volume, application refresh frequency), application opening time, application closing time, application function usage, application Program continuous running time, cumulative application running time, application installation data, application uninstallation data, etc.

The server can use the PageRank algorithm, the shortest path algorithm, and the Alternating Least Squares (ALS) algorithm to calculate the similarity between the historical behavior data of N user IDs. A relationship pair is established for user IDs whose similarity is greater than a preset similarity threshold. For example, SSOID1<->IMEI2, OPENID1<->ICCID3, SSOID2<->TEL2, IMEI2<->TEL3, IMEI2<->ICCID1, SSOID2<->OPENID1, IMEI1<->SSOID2. Then SSOID1, IMEI2, TEL3, and ICCID1 correspond to one natural person ID (for example, natural person ID1), and OPENID1, ICCID3, SSOID2, TEL2, and IMEI1 correspond to another natural person ID (for example, natural person ID2). See Table 1 for details.

Table 1

用户IDUser ID	自然人IDNatural person ID
SSOID1、IMEI2、TEL3、ICCID1SSOID1, IMEI2, TEL3, ICCID1	自然人ID1Natural person ID1
OPENID1、ICCID3、SSOID2、TEL2、IMEI1OPENID1, ICCID3, SSOID2, TEL2, IMEI1	自然人ID2Natural person ID2

Table 1 is a table of correspondence between user IDs and natural person IDs disclosed in the embodiments of the present application. As shown in Table 1, the correspondence between natural person ID1 and SSOID1, IMEI2, TEL3, and ICCID1, and the correspondence between natural person ID2 and OPENID1, ICCID3, SSOID2, TEL2, and IMEI1.

Optionally, N is greater than a preset number threshold. In step (21), the server calculates the similarity between the historical behavior data of N user IDs, specifically:

The server uses a locally sensitive hash algorithm to calculate the similarity between the historical behavior data of N user IDs.

In the embodiment of the present application, if the number of N is large, the number of user IDs is very large, and if all the user IDs of the N user IDs are calculated one by one, the amount of calculation is very large. Using local sensitive hashing algorithm to calculate the similarity between massive data can reduce the complexity of user similarity calculation.

Specifically, the hash-sensitive algorithm can construct a hash function that puts user IDs with the same or similar characteristics into the same hash bucket, and then calculates the similarity of the user IDs in the hash bucket. The local sensitive hash algorithm of this application can hash user IDs with the same or similar characteristics into the same hash bucket for similarity calculation, so that similar users can be assigned to the same hash bucket with a greater probability , Only need to calculate the similarity between user IDs in the bucket, thereby reducing the complexity of similarity calculation.

For example, the same or similar features can be location features, and user IDs with similar latitude and longitude can be hashed into the same bucket. Specifically, the Euclidean distance calculation formula can be used to determine whether two user IDs have the same or similar location characteristics.

For example, when calculating whether the first user ID and the second user ID have the same or similar location features, the location feature of the first user ID (longitude x ₁ , latitude y ₁ ) and the location of the second user ID can be obtained Features (longitude is x ₂ , latitude y ₂ ), calculate the position similarity between the first user ID and the second user ID:

If d is less than or equal to the preset threshold, it indicates that the first user ID and the second user ID have the same or similar location characteristics, and the first user ID and the second user ID are placed in the same hash bucket. If d is greater than the preset threshold, it indicates that the first user ID and the second user ID do not have the same or similar location features.

Optionally, the server can analyze the user behavior data of the newly registered user ID, analyze the user behavior data of the newly registered user ID and the user behavior data of all natural person IDs that have been stored, if the above has been stored The similarity of the natural person ID with the greatest similarity to the newly registered user ID among all the natural person IDs is greater than the preset similarity threshold, and the corresponding relationship between the natural person ID with the greatest similarity and the newly registered user ID is established.

102. The server calculates the similarity between the real-time user characteristic of the target natural person ID and at least one historical characteristic of the target historical time period of the target natural person ID, and the current time point corresponds to the target historical time period.

In the embodiment of the present application, the historical feature of the target natural person ID is obtained by integrating the historical characteristics of multiple user IDs corresponding to the target natural person ID. For example, the server can obtain the user characteristics of multiple user IDs corresponding to the target natural person ID at various time points in the past month, and classify the user characteristics at each time point according to the time period to obtain the target natural person ID at each time. At least one historical feature for each time period. Specifically, the server can classify the user characteristics of multiple user IDs corresponding to the target natural person ID at 6-9 a.m. in the past month into the historical characteristics of the first time period of the target natural person ID; the server can assign the target natural person The user characteristics of the multiple user IDs corresponding to the ID in the past month from 9-11 a.m. are included in the historical characteristics of the second time period of the target natural person ID; the server can assign multiple user IDs corresponding to the target natural person ID in the past The user characteristics at 11-14 o'clock every day within a month are classified as the historical characteristics of the third time period of the target natural person ID; the server can assign multiple user IDs corresponding to the target natural person ID at 14-17 o'clock every day in the past month The user characteristics are classified into the historical characteristics of the fourth time period of the target natural person ID; the server can include the user characteristics of multiple user IDs corresponding to the target natural person ID at 17-20 o'clock every day in the past month into the target natural person ID The historical characteristics of the fifth time period; the server can classify the user characteristics of multiple user IDs corresponding to the target natural person ID at 20-24 o'clock every day in the past month into the historical characteristics of the sixth time period of the target natural person ID; service The terminal may categorize the user characteristics of multiple user IDs corresponding to the target natural person ID at 0-6 o'clock every day in the past month into the historical characteristics of the seventh time period of the target natural person ID. The current time point is the time point at which the server obtains the real-time user characteristics of the multiple user IDs corresponding to the target natural person identification ID. If the current time point is 7 am, the current time point corresponds to the first time period (6-9 o'clock), and the server calculates at least one of the real-time user characteristics of the target natural person ID and the first time period of the target natural person ID Similarity of historical features.

After the server obtains at least one historical feature of the target natural person ID in each time period, the server can obtain the content label corresponding to each historical feature in each time period. For example, if the historical feature is the focus on advertisement A, the corresponding content tag may be advertisement A; if the historical feature is the focus on the first APP, the corresponding content tag may be the first APP.

The server obtains the content label corresponding to each historical feature in each time period, specifically:

The server acquires the first historical feature of the first time period, where the first historical feature is any one of all historical features of the first time period;

The server determines the group of natural persons with the first historical characteristic;

Determine the label corresponding to the group of natural persons;

It is determined that the content label corresponding to the first historical feature in the first time period is the label corresponding to the natural person group.

In the examples of this application, the group of natural persons with the first historical characteristic indicates that the group of natural persons has the first historical characteristic, indicating that the target natural person ID also belongs to the group of natural persons and has the corresponding characteristics of the group of natural persons. The target natural person ID pushes the content corresponding to the tag corresponding to the natural person group, thereby improving the accuracy of content pushing. A group of natural persons refers to a collection of IDs of a type of natural persons with at least one common feature.

Optionally, the server calculates the similarity between the real-time user characteristic of the target natural person ID and at least one historical characteristic of the target historical time period of the target natural person ID, specifically:

The server extracts the target digital parameter in the real-time user characteristics of the target natural person ID, and extracts at least one historical digital parameter of at least one historical characteristic of the target historical time period of the target natural person ID;

At least one Euclidean distance between the target digital parameter and the at least one historical digital parameter is calculated by using the Euclidean distance calculation formula.

Among them, the smaller the calculated Euclidean distance, the higher the similarity; the larger the calculated Euclidean distance, the lower the similarity.

The server extracts the target vector in the real-time user characteristics of the target natural person ID, and extracts at least one historical vector of at least one historical feature of the target historical time period of the target natural person ID;

The Hamming distance between the target vector and the at least one historical vector is calculated by a Hamming distance calculation formula.

Among them, the smaller the calculated Hamming distance, the higher the similarity; the larger the calculated Hamming distance, the lower the similarity.

For example, the target vector is 10 bits, and at least one history vector is 10 bits. By comparing each bit of the target vector with each bit of at least one history vector, it is the same. If they are the same, it indicates that the corresponding Hamming The distance is 0. If it is different, it means that the Hamming distance corresponding to the bit is 1. Add the Hamming distances of all bits to obtain the final Hamming distance between the vectors. The final Hamming distance is between 0 and 10. The larger the final Hamming distance, the lower the similarity; the smaller the final Hamming distance, the higher the similarity.

103. The server determines the first target historical feature that has the highest similarity with the real-time user feature of the target natural person identification ID among the at least one historical feature, and determines the first target content tag corresponding to the first target historical feature.

104. The server pushes the content corresponding to the first target content tag to the target natural person ID.

In the embodiment of the present application, each historical feature has at least one content tag corresponding to it. After calculating the similarity between the real-time user feature of the target natural person ID and at least one historical feature of the target historical time period of the target natural person ID, the server determines the highest similarity between the at least one historical feature and the real-time user feature of the target natural person ID. A target historical feature, the server pushes the content corresponding to the first target content tag to the target natural person ID.

Wherein, the first target content tag may be an advertisement content tag, and its corresponding content may be advertisement content. According to the embodiments of the present application, accurate advertisement placement can be implemented in a specific time period according to the real-time characteristics of the user.

Optionally, the real-time feature parameters also include current geographic location information. Before step 104 is performed, the following steps may also be performed:

The server determines the geographic location tag corresponding to the current geographic location information.

Step 104 may specifically be:

The server pushes the content corresponding to the first target content tag and the geographic location tag to the target natural person ID.

In the embodiment of the present application, the current geographic location information may include current GPS positioning information (for example, current longitude and latitude information). In the embodiment of the present application, when content is pushed, not only the time factor is considered, but also geographic location information is also considered, thereby further improving the accuracy of the content pushed to the target natural person ID.

In implementing the embodiments of this application, when pushing content to the target natural person ID, the content to be pushed to the target natural person ID can be determined based on the real-time user characteristics of the target natural person ID and the similarity between the real-time feature parameters and the historical characteristics of the target natural person ID And push the content corresponding to the tag to the target natural person ID. Since the historical features used for comparison are obtained based on multiple user IDs corresponding to the natural person ID, compared with the historical features using a single user ID, the historical features are greatly enriched, and the accuracy of content tags is improved, thereby Can improve the accuracy of content push.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of another content pushing method disclosed in an embodiment of the present application. Figure 2 is further optimized on the basis of Figure 1. As shown in Figure 2, the content pushing method includes the following steps.

201. The server obtains real-time user characteristics and real-time characteristic parameters of multiple user IDs corresponding to the target natural person identification ID, and generates real-time user characteristics of the target natural person identification ID based on the real-time user characteristics of the multiple user IDs, and the real-time characteristic parameters include the current time point And current geographic location information.

202. The server calculates the similarity between the real-time user characteristic of the target natural person ID and at least one historical characteristic of the target historical time period of the target natural person ID, and the current time point corresponds to the target historical time period.

203. The server determines the first target historical feature that has the highest similarity with the real-time user feature of the target natural person identification ID among the at least one historical feature, and determines the first target content tag corresponding to the first target historical feature.

Among them, the specific implementation of step 201 to step 203 can refer to step 101 to step 103 shown in FIG. 1, which will not be repeated here.

204. The server calculates the similarity between the first target content tag and the current geographic location information.

205. If the similarity between the first target content tag and the current geographic location information is greater than or equal to the preset similarity threshold, the server pushes the content corresponding to the first target content tag to the target natural person ID.

In the embodiment of the present application, the current geographic location information may include current GPS positioning information (for example, current longitude and latitude information). The server calculates the similarity between the first target content tag and the current geographic location information, specifically: the server extracts the location subtag in the first target content tag, and calculates the location subtag in the first target content tag and the current geographic location information The similarity.

Among them, the server can calculate the similarity between the location subtag in the first target content tag and the current geographic location information through the Euclidean distance calculation formula.

In the embodiment of the present application, when content is pushed, not only the time factor is considered, but also geographic location information is also considered, thereby further improving the accuracy of the content pushed to the target natural person ID.

Optionally, the method shown in FIG. 2 may further include the following steps:

(31) If the similarity between the first target content tag and the current geographic location information is less than the preset similarity threshold, the server determines the second target with the second highest similarity to the real-time user feature of the target natural person ID in at least one historical feature Historical characteristics, determine the second target content label corresponding to the second target historical characteristics;

(32) The server calculates the similarity between the second target content label and the current geographic location information;

(33) If the similarity between the second target content tag and the current geographic location information is greater than or equal to the preset similarity threshold, the server pushes the content corresponding to the second target content tag to the target natural person ID.

In this embodiment of the application, if the similarity between the first target content tag and the current geographic location information is less than the preset similarity threshold, it indicates that the current geographic location is not suitable for pushing content corresponding to the first target content tag. For example, if the first target content tag is a travel-related tag, and the current geographic location information is located in a hospital, the similarity between the two is small.

In this embodiment of the application, when the similarity between the first target content tag and the current geographic location information is less than the preset similarity threshold, the server determines the second highest similarity between the at least one historical feature and the real-time user feature of the target natural person ID. The second target historical feature determines the second target content tag corresponding to the second target historical feature. If the similarity between the second target content tag and the current geographic location information is greater than or equal to the preset similarity threshold, the server sends the target natural person ID Push the content corresponding to the second target content tag. If the similarity between the second target content label and the current geographic location information is less than the preset similarity threshold, step 201 is executed again.

The foregoing mainly introduces the solution of the embodiment of the present application from the perspective of the execution process on the method side. It can be understood that, in order to realize the above-mentioned functions, the server includes hardware structures and/or software modules corresponding to each function.
