[0040] like Figure 1 As shown, in one embodiment of the present application, a content push method is provided, including:

[0041] S100, obtaining a first directional attribute of a target object, and determining the number of the first directional attributes;

[0042] S200, acquiring all content IDs whose number of second directional attributes is not greater than that of first directional attributes from a content ID table, wherein the content ID table includes different content IDs and their corresponding second directional attributes;

[0043] S300, determining that the content ID whose second directional attribute matches the first directional attribute is the target content ID to be pushed;

[0044] S400: Acquire target content information to be pushed according to the target content ID to be pushed, and push the target content information to the target object.

[0045] In this way, the present application can quickly and accurately retrieve content information that matches the directional attributes of the target object based on the directional attributes of the target object, and push the corresponding content information to the target object. It can support large-capacity content retrieval requests and has the advantages of high retrieval efficiency and high push accuracy.

[0046] It is understandable that the push of content information includes but is not limited to the push of product information, the push of news information, the push of literary works and the push of advertisements. This embodiment takes the push of advertisements as an example. At present, when pushing advertisements, the corresponding advertisement information is usually retrieved and queried based on the user's directional attributes for push. Among them, the user's directional attributes include but are not limited to region, client, mobile phone model, age, personal hobbies, etc. In step S100, the first directional attribute of the target object can be obtained based on a large amount of data generated by the user in the process of interaction between the electronic device and the server through legal collection. These data can characterize the user's preferences, financial status or travel mode, and then when pushing advertisements to the user, it can more accurately retrieve and query the advertisement information that fits the user's preferences for push. It is understandable that when this method is applied to advertisement push, the content ID table, content ID and content information can be the corresponding advertisement ID table, advertisement ID and advertisement information; and when this method is applied to news push, the content ID table, content ID and content information can be the corresponding news ID table, news ID and news information, and so on.

[0047] In step S200, the advertisement ID table is used to store the correspondence between the advertisement ID and the corresponding second directional attribute, wherein the second directional attribute corresponding to the advertisement ID is used to characterize that the push object of the advertisement information corresponding to the current advertisement ID is the target object matching the second directional attribute. Taking the advertisement ID table including advertisement IDs with advertisement IDs Ad1 to Ad6 as an example, as shown in Table 1, the second directional attributes corresponding to the advertisement with advertisement ID Ad1 include region, hobby and gender, and Size is the number of second directional attributes. Among them, in the second directional attribute corresponding to the advertisement with advertisement ID Ad1, the region value is Beijing, Shanghai, Wuhan, the hobby is badminton and football, and the gender is male, which characterizes that the push object of the advertisement with advertisement ID Ad1 is males in Beijing, Shanghai or Wuhan who are interested in badminton or football. It can be understood that the advertisement information corresponding to the advertisement ID can be pushed to all target objects without limitation.

[0048]

[0049] Table 1

[0050] In order to facilitate advertisement retrieval, a positive index can be constructed based on the advertisement ID table for the corresponding relationship between the advertisement ID and the second directional attribute, that is, the advertisement ID can be used as the index keyword to index all the second directional attributes corresponding to the advertisement ID, or Size can be used as the index keyword to index the corresponding advertisement ID and the second directional attribute. In a specific embodiment of the present application, the advertisement information is stored in a database, and each advertisement information is mapped to a corresponding advertisement ID, such as Figure 2 As shown in the figure, the push process of the target advertisement is as follows:

[0051] When the service starts, a forward index is built based on the advertisement data in the database;

[0052] When the advertisement data is updated, for example, when advertisement information is added or deleted, the index data is updated by means of full update, and the index data is updated and synchronized by means of incremental update through the message queue MQ;

[0053] Based on the constructed forward index, the advertisement ID is queried according to the advertisement search conditions to obtain the initial result set of the advertisement ID, the final result set is calculated according to the matching rules, and the corresponding advertisement information is retrieved from the database for push.

[0054] Among them, the advertisement search condition can be that the number of second directional attributes corresponding to the advertisement ID is not greater than the number of first directional attributes of the target object. For example, the first directional attributes of the target object include female, Beijing, and badminton, and the number thereof is 3. As can be seen from Table 1, the number of second directional attributes of Ad1 to Ad6 is not greater than 3, and the initial result set of the advertisement ID is {Ad1, Ad2, Ad3, Ad4, Ad5, Ad6}, and the initial result set obtained can fully cover the advertisement IDs whose second directional attributes include at least one of female, Beijing, and badminton. In step S300, the second directional attributes corresponding to each advertisement ID in the initial result set are matched with the first directional attributes according to the matching rules to filter out the final result set. Among them, the matching rules include but are not limited to at least one second directional attribute corresponding to the advertisement ID is consistent with any first directional attribute, or each second directional attribute corresponding to the advertisement ID is consistent with one of the first directional attributes.

[0055] The step of obtaining all advertisement IDs whose number of second directional attributes is not greater than that of first directional attributes from the advertisement ID table includes:

[0056] determining a number N of first directional attributes;

[0057] All advertisement IDs whose number of second directional attributes is N, N-1, ..., Ni are obtained in sequence through the advertisement ID table until i=N, and all advertisement IDs whose number of second directional attributes is not greater than that of first directional attributes are obtained.

[0058] Similarly, taking the first directional attributes of the target object including female, Beijing, and badminton as an example, first determine the number of first directional attributes N=3, and obtain the advertisement IDs with the second directional attribute number of 3 as {Ad1, Ad2, Ad3} through the advertisement ID table, and then obtain the advertisement ID with the second directional attribute number of 2 as {Ad5} through the advertisement ID table, and then obtain the advertisement ID with the second directional attribute number of 1 as {Ad4} through the advertisement ID table, and finally obtain the advertisement ID with the second directional attribute number of 0 as {Ad6} through the advertisement ID table, so that the initial result set of advertisement IDs is {Ad1, Ad2, Ad3, Ad4, Ad5, Ad6}.

[0059] In another specific embodiment of the present application, the method further includes:

[0060] All advertisement IDs obtained from the advertisement ID table and their corresponding second directional attributes are sorted in order of the number of second directional attributes from low to high, and a target advertisement ID query index table is constructed. The target advertisement ID query index table is composed of a set of advertisement IDs with the same number of second directional attributes.

[0061] Specifically, based on the number Size of the second directional attributes corresponding to each advertisement ID as the index keyword, a positive index of Size, the advertisement ID and the second directional attribute is constructed, and the corresponding advertisement ID and the second directional attribute are indexed to obtain a target advertisement ID query index table as shown in Table 2.

[0062]

[0063]

[0064] Table 2

[0065] In this embodiment, determining the advertisement ID whose second directional attribute matches the first directional attribute as the target advertisement ID to be pushed includes: matching the second directional attribute of the advertisement ID in each set with the first directional attribute respectively to determine the target advertisement ID in each set; and using the target advertisement IDs in all sets as the target advertisement IDs to be pushed.

[0066] Among them, if there is a set in the target advertising ID query index table in which the number of second directional attributes is the same as the number of first directional attributes, the advertising ID in which the second directional attributes are consistent with the first directional attributes in the set is used as the target advertising ID in the set; if there is no set in the target advertising ID query index table in which the number of second directional attributes is the same as the number N of first directional attributes, for each set, the advertising ID with a second directional attribute that is consistent with any M of the N first directional attributes is used as the target advertising ID of the current set, where M is the number of second directional attributes of the advertising ID of the current set.

[0067] Similarly, taking the first directional attributes of the target object including female, Beijing, and badminton as an example, first determine the number of first directional attributes N=3, query the target advertising ID query index table for the advertising ID whose second directional attribute quantity is 3, and obtain the first initial advertising ID data set as {Ad1, Ad2, Ad3}, then query the index table through the target advertising ID to obtain the advertising ID whose second directional attribute quantity is 2 as {Ad5}, then query the index table through the target advertising ID to obtain the advertising ID whose second directional attribute quantity is 1 as {Ad4}, and finally query the index table through the target advertising ID to obtain the advertising ID whose second directional attribute quantity is 0 as {Ad6}, thereby obtaining the initial result set of advertising IDs.

[0068] For the obtained advertising ID sets {Ad1, Ad2, Ad3}, {Ad5}, {Ad4} and {Ad6}, the advertising IDs are screened according to the matching rules to obtain the target advertising ID of each advertising ID set. Specifically, for the advertising ID set {Ad1, Ad2, Ad3} obtained when Size = 3, it is determined that the advertising ID with the second directional attribute consistent with the three first directional attributes in {Ad1, Ad2, Ad3} is the target advertising ID, that is, when Size = 3, the result set 1 = P (female) ∧ P (Beijing) ∧ P (badminton), and it can be obtained by querying the index table of the target advertising ID that when Size = 3, there is no target advertising ID that satisfies P (female) ∧ P (Beijing) ∧ P (badminton) at the same time.

[0069] For the advertising ID set {Ad5} obtained when Size = 2, determine that the advertising ID in {Ad5} that has a second directional attribute that is consistent with any two of the three first directional attributes is the target advertising ID, that is, when size = 2, result set 2 = [P(female) ∧P(Beijing)] ∨ [P(Beijing) ∧P(badminton)] ∨ [P(female) ∧P(badminton)], and by querying the index table of target advertising ID, it can be obtained that when Size = 2, there is no target advertising ID that simultaneously satisfies [P(female) ∧P(Beijing)] ∨ [P(Beijing) ∧P(badminton)] ∨ [P(female) ∧P(badminton)].

[0070] For the advertisement ID set {Ad4} obtained when Size=1, determine that the advertisement ID in {Ad4} that has a second directional attribute that is consistent with any one of the three first directional attributes is the target advertisement ID, that is, when size=1, the result set 3=P(female)∨P(Beijing)∨P(badminton). By querying the index table of the target advertisement ID, it can be obtained that when Size=1, the target advertisement ID that satisfies P(female)∨P(Beijing)∨P(badminton) is Ad4.

[0071] For the advertisement ID set {Ad6} obtained when Size=0, when size=0, result set 4=A(0), that is, all target advertisement IDs with size=0 are Ad6.

[0072] Then the final result set = result set 1 ∨ result set 2 ∨ result set 3 ∨ result set 4, and the target advertisement IDs to be pushed are Ad4 and Ad6.

[0073] In order to further improve query efficiency and compress data storage space, in another specific embodiment of the present application, the method further includes:

[0074] Encode all advertising IDs in sequence;

[0075] For each advertisement ID, use the encoded advertisement ID as a key and the advertisement ID as a value to obtain the bitmap data of the advertisement ID;

[0076] The bitmap data of all advertisement IDs are stored in a database based on RoaringBitmap in coding order, and an advertisement ID index table is constructed. The advertisement IDs in the advertisement ID index table correspond to the advertisement IDs in the advertisement ID table one by one.

[0077] Obtain all advertisement IDs in the advertisement ID table whose number of second targeting attributes is not greater than that of first targeting attributes, including:

[0078] All advertisement IDs in the advertisement ID table whose number of second targeting attributes is not greater than that of first targeting attributes are obtained through the advertisement ID index table.

[0079] Compared with ES, RoaringBitmap has higher query efficiency and space efficiency. Taking 10W data space as an example, after compressing the data using HashSet, SkipList and RoaringBitmap, the data size is 200K, 300K and 4K respectively. If it is stored directly by advertising ID, when there are many advertising IDs, the storage space will be very large. When the service is in a multi-threaded and high query request situation, the retrieval efficiency will be seriously affected, affecting the system throughput. This embodiment constructs a dictionary ID of the advertising ID based on RoaringBitmap, and uses RunContainer to further compress the storage space of the data when storing based on RoaringBitmap, which can effectively compress the data volume and improve query efficiency.

[0080] Specifically, all advertising IDs are encoded as long values ​​starting from 1. For example, if the advertising ID is Ad1 to Ad1000, then the advertising ID is encoded as a long value from 1 to 1000. Taking Ad1 as an example, it is stored in a key-value pair as [1, Ad1], where 1 is the key and Ad1 is the value, and [1, Ad1] is the obtained bitmap data. Furthermore, all the obtained bitmap data are arranged in order from small to large or from large to small according to the advertising ID to obtain an advertising ID index table, and the encoded long value is used as the index keyword to index the corresponding advertising ID and the second directional attribute. When a new advertisement needs to be added, the new advertisement will continue to be numbered from the current maximum number without the need to modify the previous advertisement order again. Then, when the first directional attribute of the target object is obtained, the advertisement ID can be queried through the advertisement ID index table constructed based on the dictionary ID, and the second directional attribute corresponding to each advertisement ID can be obtained from the advertisement ID table according to the advertisement ID, and then the advertisement ID query index table can be constructed according to the number of the second directional attributes. The initial result set is determined according to the matching rule based on the constructed advertisement ID query index table and the final result set is calculated, thereby determining the advertisement information pushed to the target object. At the same time, when obtaining the final result set, each dictionary ID data is an array, and the second directional attribute corresponding to the advertisement ID of the dictionary ID data is the element of the array. Since the dictionary ID is constructed based on RoaringBitmap, each array in the M arrays is ordered. The M arrays are formed into one array through quick sorting, and the first element and the Nth element in the array are compared to determine whether the element appears N times. Finally, the element that appears N times is found. The time complexity of the query process is O(Log(N)) and the space complexity is O(M*N). Compared with the traditional list query, which needs to traverse all data in all advertisement ID tables and record the number of advertisements that each element appears, it has better time efficiency.
