Description

Technical Field

[0001] This invention relates to the field of data analysis, and more particularly to an information recommendation method and apparatus, and a computer-readable storage medium. Background Technology

[0002] In the ever-growing e-commerce ecosystem, various e-commerce platforms and merchants, in order to attract new customers and increase user activity and stickiness, often offer coupons or subsidies—known as Jingxiang Gift Money—to users. These coupons are funded by the platform, merchants, and promoters. As the Gift Money service becomes more widespread, the amount of data gradually increases. To meet interface performance requirements, Redis was used to heterogeneously structure the data, ultimately leading to excessive reliance on Redis. When the data volume of a single table exceeds 5 million records, the performance of multi-table joins cannot meet the requirements of the current scenario. With the promotion and popularization of the Gift Money service, in order to meet the personalized promotion of promoters, the granularity of targeting has gradually become more refined. More personalized targeting requirements have been added in dimensions such as promoters, SKUs, and platforms, including promotion slots and channels. During the iteration process, it was found that each addition of a new targeting type could be a small-scale reconstruction of the existing structure, which was time-consuming, labor-intensive, and inefficient.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0055] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The present invention provides an information recommendation method applied to a data server. Figure 1 This is an optional flowchart illustrating an information recommendation method provided by an embodiment of the present invention. Figure 1 , will combine Figure 1 The steps shown are explained.

[0056] S101, Receive multiple first resource information requests sent by multiple first terminals.

[0057] In some embodiments of the present invention, each first resource information request carries target item information, which includes information on multiple target types, such as promoter type information, platform type information, and product type information, etc.

[0058] In some embodiments of the present invention, the first terminal may be a mobile phone, tablet, or other device capable of sending information requests. The present invention does not impose any limitations on this.

[0059] S102. In response to each first resource information request, retrieve the first local item information and the first local resource information corresponding to each target type from the local inverted index library based on the target item information.

[0060] In some embodiments of the present invention, the first local resource information represents information on discounts applied to the value of an item. The local inverted index is synchronized from the inverted index in the data server. The local inverted index stores information related to multiple types of items, and the resource information corresponding to each type. Multiple target types belong to any number of the multiple types. An inverted index, also commonly referred to as a reverse index, inset archive, or reverse archive, is an indexing method used to store a mapping of the storage location of a word within a document or a set of documents in a full-text search.

[0061] In some embodiments of the present invention, the service server may respond to each resource information request by searching the local index library based on the target item information to obtain the first local item information and the first local resource information corresponding to each target type.

[0062] For example, the first local resource information could be discount coupons, no-threshold coupons, and buy-one-get-one-free promotion information, etc.

[0063] S103. Based on the first local item information and the first local resource information, perform intersection processing and verification processing between different types to obtain matching information corresponding to the target item information, and send it to the first terminal.

[0064] In some embodiments of the present invention, the service server can perform intersection processing between different types of first local item-related information and first local resource information to obtain matching item-related information and matching resource information; perform verification processing on the matching resource information to obtain verification results; determine matching information through matching resource information, matching item-related information and verification results; and finally send the matching information to the first terminal.

[0065] In some embodiments of the present invention, after receiving matching information, the first terminal may display an item-related information page or a resource information page.

[0066] In some embodiments of the present invention, the first local item-related information includes item information, promoter information, and platform information, etc. The first local resource information is item discount information.

[0067] For example, product discount information can be gift money information, referral information can be gift money-targeted referral information, platform information can be gift money-targeted platform information, and product information can be gift money-targeted product information. Gift money information, such as... Figure 2 As shown, this includes the auto-incrementing ID (id), the gift code (ciphertext) (gift_coupon_key), the creator ID (union_id), the denomination (denomination), the number of coupons (amount), the receive start time (receive_start_time), the receive end time (receive_end_time), the validity period (number of days) (effective_days), and the batch ID (batch_id). The gift-targeted referral information is as follows: Figure 3As shown, this includes an auto-incrementing primary key (id), a gift ID (plaintext) (gift_coupon_id), affiliate gift (type), gift referral target (union_id), pid, maximum amount (amount), gift creation time (gift_coupon_create_time), and start time for claiming (gift_coupon_start_time). The platform information for targeted gift claims is as follows: Figure 4 As shown, this includes an auto-incrementing primary key (id), a gift coupon ID (plaintext) (gift_coupon_id), an affiliate gift (type), a gift promotion target (union_id), and a maximum quantity (amount). Gift-specific product information is as follows: Figure 5 As shown, it includes an auto-incrementing primary key (id), gift ID (plaintext) (gift_coupon_id), skuld (sku_id), creation time (create_time), and affiliate gift (type). Existing technologies typically perform multi-table joins to determine matching information. Table 1 shows the results of a multi-table join, as shown in Table 1, which includes five parts: Key, Value, Type, Expiration Time, and Description. The keys include: "gc_"+giftCouponKey, "gc_promoterId"+promoterId, "gc_amount"+giftCouponKey+promoterId, "gc_sku"+giftCouponKey, and "gc_plat"+giftCouponKey; the values ​​include: gift money JSON, gift money key, maximum distribution limit, skuIds, and platIds; the types include: String, List, and ScoreSet; the expiration time includes: 30 days and none [asynchronous job maintenance]; the description includes: basic gift money information, gift money that can be promoted, the maximum amount of this gift money that the promoter can distribute, all skulds under this gift money, and all platlds under this gift money.

[0068] Table 1: Results of Multi-Table Query

[0069]

[0070] In some embodiments of the present invention, the matching resource information may be matching gift money, as illustrated in the existing gift money matching flowchart, such as... Figure 6As shown, promoters create gift certificates, upload them to shopping platforms, and obtain short links through link sharing. These short links are then used for promotion, which can take place on social media platforms, short video platforms, etc. The promotional message is sent to end-user devices; end-users click on the link to match the gift certificate, resulting in a product and gift certificate display page, which then returns to the end-user. The specific process for matching gift money is as follows: Redis obtains the matching result ("match_result" + promoterld + promoterld + promoterld + promoterld) and checks if it exists. If the matching result exists, the result set is returned directly. If the matching result does not exist, the promoter ID is used to query the gift money ("gc_promoterId" + promoterId). If the gift money does not exist, the result set is returned. If the gift money exists, the promoter ID is used for validation ("gc_sku" + giftCouponKey) and the promoterld is used for validation ("gc_plat" + giftCouponKey). If the validation passes, the matching result is cached ("match_result" + promoterld + promoterld + promoterld) and the result set is returned. If the validation fails, the promoter ID query for the gift money is repeated until the result set is returned.

[0071] Understandably, matching item-related information and resource information locally can improve matching efficiency and the timeliness of information.

[0072] In some embodiments of the present invention, S103 can be implemented by S1031, S1032 and S1033, as follows:

[0073] S1031. Based on the first local item information and the first local resource information, perform intersection processing between different types to obtain matching item information and matching resource information.

[0074] In some embodiments of the present invention, the service server can perform intersection processing on multiple types of item-related information in the first local item-related information to obtain matching item-related information from the multiple types of item-related information; and perform intersection processing on multiple types of resource information in the first local resource information to obtain matching resource information from the multiple types of resource information.

[0075] S1032. Perform verification processing on the matching resource information to obtain the verification result.

[0076] In some embodiments of the present invention, the business server can use a preset verification tool to verify the matching resource information, determine whether the matching resource information is valid, and thus obtain the verification result.

[0077] S1033. Based on the matching resource information, matching item information and verification results, determine the matching information and send the matching information to the first terminal.

[0078] In some embodiments of the present invention, the service server obtains the verification result. If the verification result indicates success, the matching resource information is used as the matching information; if the verification result indicates failure, the matching item information is used as the matching information; and the matching information is sent to the first terminal.

[0079] For example, if the verification result indicates that the coupon is valid, the coupon will be sent to the first terminal as matching information; if the verification result indicates that the coupon has expired, the item-related information will be sent to the first terminal as matching information.

[0080] For example, such as Figure 7 As shown, resource information can be gift money. When the shopping platform administrator maintains basic gift money information, the data server obtains gift money (equivalent to item-related and resource information, stored in MySQL and Elasticsearch) through event tracking. The obtained gift money is used in parallel to construct an inverted index + bitSet and incremental messages, which are then stored in Redis. When the instance (equivalent to the business server) starts, it fully pulls the inverted index + bitSet from Redis to build a local index, initializing the local inverted index + bitSet. After startup, a timer is set to periodically pull incremental consumption messages based on the local index location. This ensures continuous near real-time synchronization between the local index and the Redis index. Simultaneously, downstream systems can directly provide matching and verification services using local data.

[0081] For example, such as Figure 8 As shown, the downstream (equivalent to the first terminal) sends the skuld, promoter ID, and platform ID (equivalent to target item information and its corresponding resource information) to the business server through the matching interface. Locally, it obtains BitSet result set 1 by combining the sku enumeration and skuld, BitSet result set 2 by combining the platform enumeration and platform ID, BitSet result set 3 by combining the promoter enumeration and promoter ID, and BitSet result set n by combining other enumerations and other IDs. All types of information are processed locally under Map<Directed Dimension Enumeration, Map<Dimension Value, Inverted Index>local. After intersecting BitSet result set 1, BitSet result set 2, BitSet result set 3, and BitSet result set n, etc., the BitSet result set (equivalent to matching resource information) is obtained. This is then verified by calling the downstream interface verification library through a filter, and the matching result (equivalent to matching information) is returned to the downstream.

[0082] Understandably, by performing intersection processing and verification processing on the first local item information and the first local resource information, the validity and accuracy of the sent matching information are ensured.

[0083] In some embodiments of the present invention, S104-S106 are executed before S102, as follows:

[0084] S104. Upon initial startup or at a preset time, send an initialization information request to the data server.

[0085] In some embodiments of the present invention, the business server sends an initialization information request to the data server upon initial startup; or, the business server sends an initialization information request to the data server at a preset time point.

[0086] For example, the preset time could be 12:00 AM every day.

[0087] S105. Receive the full set of item-related information and corresponding full set of resource information sent by the data server in response to the initialization information request.

[0088] In some embodiments of the present invention, the total amount of item-related information includes item-related information of multiple types. The total amount of resource information includes resource information corresponding to multiple types.

[0089] In some embodiments of the present invention, the business server receives the full amount of item-related information and the full amount of resource information corresponding to the full amount of item-related information sent by the data server in response to the initialization information request.

[0090] S106. Based on all item-related information and all resource information, construct a local inverted index library.

[0091] In some embodiments of the present invention, a local inverted index library stores local item-related information and local resource information.

[0092] In some embodiments of the present invention, the business server can synchronize multiple types of item-related information and their corresponding multiple types of resource information in the initial local inverted index library to obtain multiple types of local item-related information and their corresponding multiple types of resource information, thus forming a local inverted index library.

[0093] For example, such as Figure 9As shown, based on multiple types of item-related information, such as referral type, platform type, and product type, the targetlds redis.hKeys(...type) are determined, thus determining hmGet(...type, targetlds), and finally determining the local MAP[Map<targeted dimension enumeration, Map<dimension value, inverted index>](Map <String,Map<String,BitSet> >).

[0094] An exemplary diagram of a local inverted index library, such as... Figure 10 As shown, the local inverted index consists of a Map<Directed Dimension Enumeration, a Map<Dimension Value, and a bitSet after the inverted order of the gift ID. This includes information on referral type, platform type, and product type. Each type further includes specific type information; for example, the referral type includes unionld1 and pld; the platform type includes media1 and media2; and the product type includes skuld1 and skuld2. Each specific type information is formatted as giftCouponKey1, giftCouponKey2, etc. Each specific type information is stored in byte array format, such as 110000, etc.

[0095] Understandably, building a local inverted index based on all item-related information and their corresponding resource information obtained from the data server can reduce the data storage pressure on the data server.

[0096] In some embodiments of the present invention, S201-S205 are also executed after S106, as follows:

[0097] S201. Send a consumption task request to the data server.

[0098] In some embodiments of the present invention, the service server sends a consumption task request to the data server.

[0099] S202. In response to the consumption task request, based on the current location, pull a preset number of first incremental messages from the incremental message queue in the data server.

[0100] In some embodiments of the present invention, the first incremental message represents newly added item-related information and corresponding resource information, or changed item-related messages and corresponding resource information.

[0101] In some embodiments of the present invention, in response to a consumption task request, the service server pulls a preset number of first incremental messages from the incremental message queue in the data server based on the current location. The preset number is typically 10 messages.

[0102] S203. Based on the message type corresponding to each of the first incremental messages, obtain the second local item information and the second local resource information of the same type in the local inverted index library.

[0103] In some embodiments of the present invention, the business server can search in the local inverted index library according to the message type corresponding to each of the first incremental messages to obtain the second local item-related information and the second local resource information that are consistent with the message type corresponding to each of the first incremental messages.

[0104] S204. Based on the message identifiers corresponding to the first incremental messages, update the second local resource information and the item-related information under the corresponding type, and determine the updated second local item-related information, second local resource information, and next location in the local inverted index.

[0105] In some embodiments of the present invention, the next position is used to determine the position from which to pull a new message from the incremental message queue; wherein, the corresponding initial position of each update of the local inverted index is the first message in the incremental message queue.

[0106] In some embodiments of the present invention, the business server can update the second local resource information and the item-related information under the corresponding type according to the message identifier corresponding to each of the first incremental messages, so as to obtain the updated second local item-related information, second local resource information and next location in the local inverted index library.

[0107] For example, such as Figure 11 As shown, the business server (local) retrieves incremental messages (equivalent to the first incremental message) from the incremental message queue (scoreSet) in the data server (redis) based on the local position (equivalent to the current position), and performs message type strategy adaptation. The types include: adding bonus, adding promoter, adding platform, adding product, deleting bonus, deleting site owner, deleting product, stopping and updating basic information; updating the second local item information, the second local resource information and the local position (equivalent to the next position).

[0108] It is understandable that updating the local inverted index can ensure the accuracy of the information in the local inverted index when item-related or resource-related information changes.

[0109] This invention provides an information recommendation method for data servers, which will be described in detail below.

[0110] S301, Receive information request from the second terminal.

[0111] In some embodiments of the present invention, the information request carries initial item information and initial resource information. Both the initial item information and the initial resource information are pre-set information on the second terminal.

[0112] S302. In response to the information request, compress the initial item-related information and initial resource information to obtain the full item-related information and full resource information.

[0113] In some embodiments of the present invention, the initial resource information corresponds to the initial item information, and the total item information corresponds to the total resource information.

[0114] In some embodiments of the present invention, the data server can respond to an information request by classifying the initial item-related information to obtain multiple types of item-related information; for each type of item-related information, further subdivision processing is performed to obtain unit information corresponding to each type of item-related information. The data format of the unit information is converted to obtain first minimum unit information; the first minimum unit information is compressed to obtain second minimum unit information. The full set of item-related information is determined using the second minimum unit information. The initial resource information is then compressed in the same way as the initial item-related information to obtain the full set of resource information.

[0115] In some embodiments of the present invention, S302 can be implemented by S3021, S3022, S3023, S3024, S3025 and S3026, as follows:

[0116] S3021. In response to the information request, the initial item-related information is classified and processed to obtain item-related information of multiple types.

[0117] In some embodiments of the present invention, the data server may respond to an information request by classifying the initial item-related information according to the information type to obtain multiple types of item-related information.

[0118] For example, the initial item-related information includes information about promoters, platforms, and products. After categorizing these information, we can obtain item-related information for promoters, platform-related items, and product-related items.

[0119] S3022. For each type of item-related information, perform further subdivision processing to obtain the unit information corresponding to each type of item-related information.

[0120] In some embodiments of the present invention, the data server performs subdivision processing on the relevant information of each type of item according to the information identifier in each type, so as to obtain the unit information corresponding to the relevant information of each type of item.

[0121] For example, after the relevant information of items of different platform types is processed in a subdivided manner, we can obtain information about platform 1, platform 2, platform 3, and so on.

[0122] S3023. Convert the data format of the unit information to obtain the first smallest unit information.

[0123] In some embodiments of the present invention, the data server converts the data format of the unit information into a bitmap (bitSet) format to obtain the first minimum unit information.

[0124] S3024. Compress the first minimum unit information to obtain the second minimum unit information.

[0125] In some embodiments of the present invention, the second smallest unit information is data in the form of a byte array.

[0126] In some embodiments of the present invention, the data server may compress the first minimum unit information to obtain the second minimum unit information.

[0127] S3025. Based on the information of the second smallest unit, determine the relevant information of all items.

[0128] In some embodiments of the present invention, the data server summarizes the second smallest unit information under all types to determine the relevant information of all items.

[0129] S3026. Perform the same compression process on the initial resource information as on the initial item information to obtain the full resource information.

[0130] In some embodiments of the present invention, the data server can perform the same compression processing on the initial resource information as on the initial item information to obtain the full resource information.

[0131] It is understandable that compressing the initial resource information and initial item information to obtain the full item information and full resource information reduces storage space and can improve storage efficiency.

[0132] S303. Based on all item-related information, determine the inverted index library in the data server.

[0133] In some embodiments of the present invention, the data server can determine the inverted index library in the data server by using all item-related information in a certain arrangement.

[0134] S304. Store all resource information in an inverted index database on the data server according to the corresponding relationship.

[0135] In some embodiments of the present invention, the data server can store all resource information in an inverted index library in the data server according to the correspondence relationship.

[0136] An exemplary diagram of an inverted index database in a data server, such as...

[0137] S305, Receive initialization information request sent by the service server.

[0138] In some embodiments of the present invention, the data server receives an initialization information request sent by the business server.

[0139] S306. In response to the initialization information request, send all item-related information and their corresponding resource information to the business server so that the business server can synchronously determine the local inverted index library.

[0140] In some embodiments of the present invention, in response to an initialization information request, the data server sends all item-related information and its corresponding full resource information to the business server, so that the business server can synchronously determine the local inverted index library.

[0141] It is understandable that compressing the initial resource information and initial item information to obtain the full item information and full resource information reduces storage space and can improve storage efficiency. At the same time, sending the full item information and its corresponding full resource information to the business server can facilitate local storage and reduce the storage pressure on the data server.

[0142] In some embodiments of the present invention, S307, S308 and S309 are also executed after S304, as follows:

[0143] S307, Received an incremental message from the second terminal.

[0144] In some embodiments of the present invention, the incremental message carries change information. The change information includes newly added item-related information and corresponding resource information, or changed item-related information and corresponding resource information. The message structure of the incremental message includes a message type and a message identifier.

[0145] An example message structure for an incremental message is as follows:

[0146]

[0147] Among them, "platList", "skuList", "giftCouponKey" and "operate Type" are message types; "1: Add Gift Money, 2: Add Promoter, 4: Add Platform", etc. are message identifiers.

[0148] S308. Update the information on all items and all resources in the data server according to the message type of the incremental message.

[0149] In some embodiments of the present invention, all item-related information and all resource-related information are stored in the inverted index library of the data server.

[0150] In some embodiments of the present invention, the data server can obtain item-related information and resource information of the corresponding type in the data server based on the message type of the incremental message. Based on the message identifier of the incremental message, the item-related information and resource information of the corresponding type in the data server are updated to determine the updated full item-related information and full resource information in the data server.

[0151] In some embodiments of the present invention, S302 can be implemented by S3021 and S3022, as follows:

[0152] S3021. Based on the message type of the incremental message, obtain the item-related information and resource information of the corresponding type in the data server.

[0153] In some embodiments of the present invention, the data server can obtain item-related information and resource information of the corresponding type in the data server based on the information type of newly added item-related information and the information type of corresponding resource information. Alternatively, it can obtain item-related information and resource information of the corresponding type in the data server based on the information type of changed item-related information and the information type of corresponding resource information.

[0154] S3022. Based on the message identifier of the incremental message, update the item-related information and resource information of the corresponding type in the data server, and determine the updated full item-related information and full resource information in the data server.

[0155] In some embodiments of the present invention, the data server can update the item-related information and resource information of the corresponding type in the data server based on the information identifiers of newly added item-related information and the corresponding resource information, thereby determining the updated total item-related information and total resource information in the data server. Alternatively, the data server can update the item-related information and resource information of the corresponding type in the data server based on the information identifiers of changed item-related information and the corresponding resource information, thereby determining the updated total item-related information and total resource information in the data server.

[0156] It is understandable that if the item-related and resource-related information of the second terminal changes, timely updating of all item-related and resource-related information in the data server can ensure the validity and accuracy of the data in the data server.

[0157] In some embodiments of the present invention, S309 and S3010 are also executed after S308, as follows:

[0158] S309. Store the incremental message in the incremental message queue.

[0159] In some embodiments of the present invention, the data server may store incremental messages in an incremental message queue.

[0160] For example, such as Figure 13 As shown, information can be obtained through event tracking. This information includes new gift money (equivalent to information related to newly added items and corresponding resource information) and changes to gift money (equivalent to information related to changed items and corresponding resource information). Based on the new and changes to gift money, corresponding unit-based additions or updates are performed in Redis (equivalent to a data server). The strategy is adapted according to the message type to determine whether to update or add information. The types include: adding gift money, adding promoters, adding platforms, adding products, deleting gift money, deleting site owners, deleting products, stopping, and updating basic information. Finally, the incremental messages are stored in the incremental message queue (List).

[0161] S3010: Upon receiving a consumption task request, the incremental message queue is sent to the business server in response to the consumption task request.

[0162] In some embodiments of the present invention, the data server may receive a consumption task request sent by the business server, and in response to the consumption task request, send an incremental message queue to the business server.

[0163] Understandably, when item-related and resource-related information changes on the second terminal, timely updates to all item-related and resource-related information on the data server ensure the validity and accuracy of the data. Storing the changed information in an incremental message queue and sending consumption service requests to the business server facilitates data updates on the business server.

[0164] This invention provides an information recommendation method, such as... Figure 14 As shown, the following steps will provide a detailed explanation.
