As shown in fig. 1, in an embodiment of the present application, a content pushing method is provided, including:

s100, obtaining a first orientation attribute of a target object, and determining the number of the first orientation attribute;

s200, acquiring all content IDs of which the number of the second directional attributes is not more than that of the first directional attributes from a content ID table, wherein the content ID table comprises different content IDs and corresponding second directional attributes;

s300, determining the content ID matched with the first orientation attribute and the second orientation attribute as the target content ID to be pushed;

s400, acquiring the target content information to be pushed according to the target content ID to be pushed, and pushing the target content information to the target object.

Therefore, the method and the device can quickly and accurately retrieve and query the content information matched with the directional attribute of the target object according to the directional attribute of the target object, push the corresponding content information to the target object, support a large-capacity content retrieval request, and have the advantages of high retrieval efficiency and high pushing accuracy.

It is understood that the push of content information includes, but is not limited to, push of product information, push of news information, push of literary works, and push of advertisements. In this embodiment, advertisement pushing is taken as an example, and currently, when an advertisement is pushed, advertisement information corresponding to a search query is generally retrieved and pushed based on a targeting attribute of a user. The directional attributes of the user include, but are not limited to, region, client, model of mobile phone, age, personal preference, etc. In step S100, the first directional attribute of the target object may be obtained based on a large amount of legally collected data generated by the user in the interaction process between the electronic device and the server, and the data may represent characteristics of the user, such as a favorite, a financial status, or a trip mode, so that when an advertisement is pushed to the user, advertisement information that is preferred by the user may be more accurately retrieved, queried, and pushed. It can be understood that when the method is applied to advertisement push, the content ID table, the content ID and the content information may be corresponding advertisement ID table, advertisement ID and advertisement information; when the method is applied to news pushing, the content ID table, the content ID and the content information can be the corresponding news ID table, news ID and news information, and so on.

In step S200, the advertisement ID table is used to store a corresponding relationship between the advertisement ID and a corresponding second targeting attribute, where the second targeting attribute corresponding to the advertisement ID is used to represent that a push object of the advertisement information corresponding to the current advertisement ID is a target object matched with the second targeting attribute. Taking the advertisement ID table including advertisement IDs Ad 1-Ad 6 as an example, as shown in table 1, the second targeting attribute corresponding to the advertisement with the advertisement ID Ad1 includes region, hobby and gender, and Size is the number of the second targeting attribute. In the second targeting attribute corresponding to the advertisement with the Ad1 as the advertisement ID, the region value is beijing, shanghai, wuhan, the preference is for badminton and football, the gender is male, the pushing object of the advertisement with the Ad1 as the advertisement is beijing, shanghai or wuhan, the male with the preference for badminton or football can understand that the advertisement information corresponding to the advertisement ID can be pushed to all target objects.

TABLE 1

In order to facilitate advertisement retrieval, a forward index may be constructed for the correspondence between the advertisement ID and the second targeting attribute based on the advertisement ID table, that is, all the second targeting attributes corresponding to the advertisement ID may be indexed by using the advertisement ID as an index key, or the corresponding advertisement ID and the second targeting attribute may be indexed by using Size as an index key. In a specific embodiment of the present application, the advertisement information is stored in the database, and each piece of advertisement information is mapped with a corresponding advertisement ID, as shown in fig. 2, the pushing process of the target advertisement is as follows:

when the service is started, a forward index is constructed according to the advertisement data in the database;

when the advertisement data is updated, for example, the advertisement information is added or deleted, the index data is updated in a full-quantity updating mode, and the index data is updated and synchronized in an incremental updating mode through the message queue Mq;

based on the constructed forward index, inquiring the advertisement ID according to the advertisement retrieval condition to obtain an initial result set of the advertisement ID, calculating a final result set according to the matching rule, and taking out corresponding advertisement information from the database for pushing.

The advertisement retrieval condition can be that the number of the second directional attributes corresponding to the advertisement ID is not greater than the number of the first directional attributes of the target object. For example, if the first directional attributes of the target object include maiden, beijing, and badminton, the number thereof is 3, and as can be seen from table 1, if the number of the second directional attributes of Ad1 to Ad6 is not greater than 3, the initial result set of the advertisement IDs is { Ad1, Ad2, Ad3, Ad4, Ad5, Ad6}, and the thus obtained initial result set can fully cover the advertisement IDs of which the second directional attributes at least include one of maiden, beijing, and badminton. In step S300, the second directional attributes corresponding to the advertisement IDs in the obtained initial result set are matched with the first directional attributes according to a matching rule, so as to screen out a final result set. The matching rule includes, but is not limited to, that at least one second targeting attribute corresponding to the advertisement ID is consistent with any one of the first targeting attributes, or that each second targeting attribute corresponding to the advertisement ID is consistent with one of the first targeting attributes.

Wherein, obtaining all advertisement IDs of which the number of the second directional attributes is not more than the number of the first directional attributes from the advertisement ID table comprises:

determining the number N of first orientation attributes;

and sequentially acquiring all advertisement IDs of which the number of the second directional attributes is N, N-1, … and N-i through the advertisement ID table until i is equal to N, and acquiring the advertisement IDs of which the number of the second directional attributes is not more than that of the first directional attributes.

Similarly, taking the example that the first directional attribute of the target object includes maiden, beijing, and badminton as an example, first, the number N of the first directional attribute is determined to be 3, the advertisement ID of which the second directional attribute number is 3 is obtained as { Ad1, Ad2, Ad3} through the advertisement ID table, the advertisement ID of which the second directional attribute number is 2 is obtained as { Ad5} through the advertisement ID table, the advertisement ID of which the second directional attribute number is 1 is obtained as { Ad4} through the advertisement ID table, and finally, the advertisement ID of which the second directional attribute number is 0 is obtained as { Ad6} through the advertisement ID table, so that the initial result set of the advertisement IDs is { Ad1, Ad2, Ad3, Ad4, Ad5, Ad6 }.

In another specific embodiment of the present application, the method further comprises:

and sequencing all the advertisement IDs acquired from the advertisement ID table and the corresponding second directional attributes thereof according to the sequence of the number of the second directional attributes from low to high, and constructing a target advertisement ID query index table, wherein the target advertisement ID query index table is composed of a set of advertisement IDs with the same number of the second directional attributes.

Specifically, based on the number Size of the second targeting attributes corresponding to each advertisement ID as an index key, a forward index of Size, advertisement ID and the second targeting attributes is constructed, the corresponding advertisement ID and the second targeting attributes are indexed, and a target advertisement ID query index table is obtained as shown in table 2.

TABLE 2

In this embodiment, determining that the advertisement ID matching the second targeting attribute with the first targeting attribute is the target advertisement ID to be pushed includes: matching the second directional attributes of the advertisement IDs in each set with the first directional attributes respectively to determine the target advertisement IDs in each set; and taking the target advertisement ID in all the sets as the target advertisement ID to be pushed.

If a set with the number of the second directional attributes identical to the number of the first directional attributes exists in the target advertisement ID query index table, taking the advertisement ID with the second directional attributes and the first directional attributes in the set consistent as the target advertisement ID in the set; if the targeted advertisement ID query index table does not have sets with the number of the second directional attributes identical to the number N of the first directional attributes, regarding each set, using the advertisement ID with the second directional attributes consistent with any M first directional attributes in the N first directional attributes as the targeted advertisement ID of the current set, wherein M is the number of the second directional attributes of the advertisement ID of the current set.

Similarly, taking the example that the first directional attribute of the target object includes maid, beijing, and badminton as an example, first, determining that the number N of the first directional attribute is 3, querying the advertisement ID whose number of the second directional attribute is 3 in the target advertisement ID query index table to obtain a first initial advertisement ID data set of { Ad1, Ad2, Ad3}, then querying the index table by the target advertisement ID to obtain an advertisement ID whose number of the second directional attribute is 2 of { Ad5}, then querying the index table by the target advertisement ID to obtain an advertisement ID whose number of the second directional attribute is 1 of { Ad4}, and finally querying the index table by the target advertisement ID to obtain an advertisement ID whose number of the second directional attribute is 0 of { Ad6}, and further obtain an initial result set of the advertisement ID.

And aiming at the obtained advertisement ID sets { Ad1, Ad2, Ad3}, { Ad5}, { Ad4} and { Ad6}, respectively screening the advertisement IDs according to matching rules to obtain the target advertisement ID of each advertisement ID set. Specifically, it is determined that, among the advertisement ID sets { Ad1, Ad2, Ad3} obtained when Size ═ 3, an advertisement ID having a second targeting attribute that matches all of the 3 first targeting attributes is a target advertisement ID, that is, Size ═ 3, in { Ad1, Ad2, Ad3}, the result set 1 ═ P (female) Λ P (beijing) ^ P (badminton) is obtained by querying the index table with the target advertisement ID, and when Size ═ 3, there is no target advertisement ID that satisfies both P (female) Λ P (beijing) ^ P (badminton).

For an advertisement ID set { Ad5}, which is obtained when the Size is 2, it is determined that, in { Ad5}, an advertisement ID having a second directional attribute that is consistent with any 2 first directional attributes among 3 first directional attributes is a target advertisement ID, that is, the Size is 2, a result set 2 ═ P (female) Λ P (beijing) ] [ P (beijing) ^ P (badminton) ] [ P (female) Λ P (badminton) ], which is obtained by querying an index table by using the target advertisement ID, and when the Size is 2, a target advertisement ID that simultaneously satisfies [ P (female) ^ P (beijing) ] [ P (beijing) ^ P (badminton) ] [ P (female) ^ P (badminton) ], does not exist.

For the advertisement ID set { Ad4}, which is obtained when the Size is 1, it is determined that, in { Ad4}, an advertisement ID having a second targeting attribute that is consistent with any 1 first targeting attribute of the 3 first targeting attributes is a target advertisement ID, that is, when the Size is 1, a result set 3 ═ P (female) P (beijing) v.p (shuttlecock), which can be obtained by querying an index table with the target advertisement ID, and when the Size is 1, the target advertisement ID satisfying P (female) v.p (beijing) P (shuttlecock) is Ad 4.

For the set of Ad IDs { Ad6} obtained when Size is 0, the result set 4 is a (0), i.e., all target Ad IDs with Size 0 are Ad 6.

The final result set is result set 1, result set 2, result set 3, result set 4, and the obtained target advertisement IDs to be pushed are Ad4 and Ad 6.

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

encoding all advertisement IDs in sequence;

aiming at each advertisement ID, taking the coded advertisement ID as a key and the advertisement ID as a value to obtain bitmap data of the advertisement ID;

storing bitmap data of all advertisement IDs into a database based on Roaring bitmap according to a coding sequence, and constructing an advertisement ID index table, wherein the advertisement IDs in the advertisement ID index table correspond to the advertisement IDs in the advertisement ID table one by one;

acquiring all advertisement IDs of which the number of the second directional attributes is not more than that of the first directional attributes from an advertisement ID table, wherein the steps comprise:

and acquiring all advertisement IDs of which the number of the second directional attributes is not more than that of the first directional attributes in the advertisement ID table through the advertisement ID index table.

The Roaring bitmap has higher query efficiency and space efficiency than ES, taking 10W data space as an example, after data is compressed by HashSet, SkipList and Roaring bitmap, the data sizes are 200K, 300K and 4K respectively. If the advertisement ID is directly stored, when there are many advertisement IDs, the storage space is very large, and when the service is in a multi-thread and high query request condition, the retrieval efficiency is seriously affected, which affects the throughput of the system. In the embodiment, the dictionary ID of the advertisement ID is constructed based on the Roaring bitmap, and the data storage space is further compressed by RunContainer when the Roaring bitmap is stored, so that the data volume can be effectively compressed, and the query efficiency is improved.

Specifically, all advertisement IDs are encoded as long type numerical values starting from 1, for example, if the advertisement IDs are Ad1 to Ad1000, the advertisement IDs are encoded as long type numerical values of 1 to 1000, and stored as [1, Ad1] in a key value pair manner, taking Ad1 as an example, where 1 is a key, Ad1 is a value, and [1, Ad1] is the obtained bitmap data. Further, all the obtained bitmap data are arranged according to the sequence of the advertisement IDs from small to large or from large to small to obtain an advertisement ID index table, and the coded long type numerical value is used as an index key word to index the corresponding advertisement ID and the second directional attribute. When the new advertisement is needed, the new advertisement is numbered continuously from the current maximum number without modifying the previous advertisement sequence again. And further, under the condition that the first directional attribute of the target object is obtained, the advertisement ID is inquired through an advertisement ID index table constructed based on the dictionary ID, the second directional attribute corresponding to each advertisement ID is obtained from the advertisement ID table according to the advertisement ID, then the advertisement ID inquiry index table is constructed according to the number of the second directional attributes, the initial result set is determined according to the constructed advertisement ID inquiry index table and the matching rule, the final result set is obtained through calculation, and therefore the advertisement information pushed to the target object is determined. Meanwhile, when a final result set is obtained, each piece of dictionary ID data is 1 array, a second directional attribute corresponding to the advertisement ID of the piece of dictionary ID data is used as an element of the array, the dictionary ID is constructed based on Roaring bitmap, each array in the M arrays is ordered, the M arrays form 1 array through rapid sequencing, whether the element appears for N times is judged by comparing whether the first element and the Nth element in the arrays are the same, the element appearing for N times is finally found, the time complexity O (Log (N)) and the space complexity O (M) of the query process are compared with the traditional list query, all data in all advertisement ID tables need to be traversed, the advertisement frequency appearing in each element is recorded, and the time efficiency is better.

As shown in fig. 3, a second aspect of the present application provides a content pushing apparatus, including:

acquiring target content IDs of which the number of the second directional attributes is not more than that of the first directional attributes from a content ID table, wherein the content ID table comprises different target content IDs and corresponding second directional attributes;
