[0024] The following will clearly and completely describe the technical solutions in this specification in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this specification.

[0025] In the description of this specification, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In the description of this specification, it should be noted that, unless otherwise expressly specified and limited, "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices. For those of ordinary skill in the art, the specific meanings of the above terms in this specification can be understood according to the specific circumstances. In addition, in the description of this specification, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0026] In related technologies, service platforms use a fixed system recommendation algorithm to recommend information to users in the form of information distribution, which is often referred to as a push model based on system algorithm recommendation distribution. The information delivery function focuses on the recommendation scoring ability of the system recommendation algorithm. Information is ranked according to the system recommendation algorithm's score, and this serves as the basis for distributing recommended information cards to users. Using the aforementioned approach, on the one hand, the service platform lacks a medium for dialogue with users and is unable to actively or passively perceive and obtain users' individual preferences, needs, and habits; on the other hand, the service platform's recommendation process is relatively simple and fails to achieve a link that combines users' personal preferences with system algorithm recommendations; on the other hand, traditional financial service platforms lack a continuous follow-up feedback mechanism, resulting in the platform's recommendation strategy being unable to adjust in a timely manner according to changes in users' personal preferences. Based on this, in information recommendation practice, a large number of users often feedback that they often scroll through the service page for a long time without finding the information of interest to the user. The information recommendation methods in related technologies have certain limitations.

[0027] The present specification is described in detail below with reference to specific embodiments.

[0028] Please refer to Figure 1, which is a schematic diagram of a scenario of an information recommendation system provided in this specification. As shown in Figure 1, the information recommendation system may include at least a client cluster and a service platform 100.

[0029] The client cluster may include at least one client, as shown in FIG1 , specifically including client 1 corresponding to user 1, client 2 corresponding to user 2, ..., client n corresponding to user n, where n is an integer greater than 0.

[0030] Each client in the client cluster can be an electronic device with communication capabilities, including but not limited to wearable devices, handheld devices, personal computers, tablet computers, in-vehicle devices, smartphones, computing devices, or other processing devices connected to a wireless modem. Electronic devices may be called different names in different networks, such as user equipment, access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, cellular phone, cordless phone, personal digital assistant (PDA), electronic devices in 5G network or future evolution network, etc.

[0031] The service platform 100 can be a separate server device, such as a rack-mounted, blade, tower, or cabinet-mounted server device, or a workstation, mainframe computer, or other hardware device with strong computing capabilities; it can also be a server cluster composed of multiple servers. The servers in the service cluster can be symmetrically composed, wherein each server has equivalent functions and status in the transaction link, and each server can provide services to the outside world independently. The independent service can be understood as not requiring the assistance of other servers.

[0032] In one or more embodiments of the present specification, the service platform 100 may establish a communication connection with at least one client in the client cluster, and complete data interaction in the information recommendation process based on the communication connection.

[0033] It should be noted that the service platform 100 and at least one client in the client cluster establish a communication connection through a network for interactive communication, wherein the network can be a wireless network or a wired network, the wireless network includes but is not limited to a cellular network, a wireless local area network, an infrared network or a Bluetooth network, and the wired network includes but is not limited to Ethernet, a universal serial bus (USB) or a controller area network. In one or more embodiments of the specification, technologies and / or formats including Hypertext Markup Language (HTML) and Extensible Markup Language (XML) are used to represent data exchanged over the network (such as a target compressed package). In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), and Internet Protocol Security (IPsec) can also be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies can also be used to replace or supplement the above-mentioned data communication technologies.

[0034] The information recommendation system embodiments provided in this specification share the same concept as the information recommendation method described in one or more embodiments. The execution entity corresponding to the information recommendation method described in one or more embodiments of this specification may be the aforementioned service platform 100; the execution entity corresponding to the information recommendation method described in one or more embodiments of this specification may also be the electronic device corresponding to the client, depending on the actual application environment. The implementation process of the information recommendation system embodiments can be found in the following method embodiments and will not be further described here.

[0035] Based on the scenario diagram shown in FIG1 , the information recommendation method provided by one or more embodiments of this specification is described in detail below.

[0036] Please refer to Figure 2, which provides a flowchart of an information recommendation method for one or more embodiments of this specification. This method can be implemented using a computer program and run on an information recommendation device based on the von Neumann architecture. The computer program can be integrated into an application or run as a standalone tool application. The information recommendation device can be a service platform.

[0037] Specifically, the information recommendation method includes the following steps.

[0038] S102: Determine information preference category signature information of a target user using a preference category query mode, determine at least one information recommendation card for the target user based on the information preference category signature information, and display a transaction service page including the information recommendation card.

[0039] The preference category inquiry mode refers to determining the user's preference category (which can be an interest category or a subcategory under an interest category) through human-computer interactive inquiry. It can be understood as a mode or mechanism that determines the user's browsing intention through human-computer interactive inquiry to determine the preference category and recommend relevant preference cards to the user.

[0040] The information preference category tag information refers to one or more information preference categories determined for the target user. Usually, an information category may also correspond to one or more subcategory tags.

[0041] The interactive inquiry involved in the preference category inquiry mode refers to the intention inquiry interaction of the recommending user on the reference category item. The interactive inquiry method includes but is not limited to clicking, reading, interacting, etc. to determine the user's preference category (which can be an interest category or a subcategory under an interest category). Using the preference category inquiry mode, one or more information preference categories of the target user can be determined, thereby obtaining the preference category signature information.

[0042] The information recommendation card is a card container for carrying recommended information. The recommended information is displayed to the user in the form of the information recommendation card.

[0043] In this specification, the recommended information in the information recommendation card includes but is not limited to information types such as video, image, text and voice.

[0044] The transaction service page is the functional page of the transaction service provided to the outside by the service platform involved in this manual.

[0045] Optionally, transaction services include but are not limited to financial transaction services, shopping transaction services, express delivery transaction services, etc.

[0046] Specifically, the service platform first scores and ranks the "service supply information cards" based on an information recommendation algorithm, preliminarily determining the initial information cards for the ranking. It then uses a preference category query model to determine the target user's information preference category signature information. Then, using this information preference category signature information, it determines the information recommendation card for the target user. It then determines the transaction service page containing the information recommendation card and displays it to the target user. For example, the service platform sends the transaction service page data to the target user's client, which then displays the transaction service page based on the transaction service page data.

[0047] In a specific implementation scenario, as shown in Figure 3, Figure 3 is a schematic diagram of a scenario for transaction service page processing. A user enters the transaction service application provided by the service platform for browsing. The recommendation system of the service platform uses an information recommendation algorithm to score the "service supply information card" to obtain a card recommendation score. Based on the card recommendation score, the "service supply information card" is recommended and sorted as a whole, and then these "service supply information cards" are recalled (the service supply information card contains transaction service information to recommend to users for reference). The "service supply information card" is the initial information card preliminarily determined by the platform using the information recommendation algorithm; then the "service supply information card" is subjected to a rough algorithm intervention, that is, the information recommendation algorithm is called to score and sort the information category tags through the algorithm, and the priority order of the information category tags between the various information category tags is arranged. At this time, the information preference category tag has the highest priority, and then the initial information card is allocated under each information category tag.

[0048] Furthermore, the initial information cards under each information category tag are finely sorted and intervened: the preference category tag information is queried from the DB (database), and the information recommendation cards of interest in the initial information cards are filtered out from the initial information cards according to the user preference subcategory tags in the preference category tag selected by the user. The rest are ordinary system recommendation cards. At this time, the initial information cards are divided into information recommendation cards of interest and ordinary system recommendation cards, and then the priority of the information recommendation cards under one or more information category target tags is increased so that the priority of the information recommendation cards under the information category target tags is higher than that of the ordinary system recommendation cards. The ordinary system recommendation cards are ranked after the information recommendation cards according to the card recommendation score. After completing the above operations, the other information data of the complete information card is finally assembled to complete the update of the transaction service page, and the updated transaction service page is returned to the user terminal used by the target user.

[0049] Furthermore, if the preference category tag information does not contain a user preference subcategory tag under the preference category tag, the initial information cards under each information category tag are sorted according to the card recommendation score, and finally the remaining information data of the completed information cards are assembled to complete the update of the transaction service page, and the updated transaction service page is returned to the user terminal used by the target user. In this case, the user usually only selects the information preference category tag through the preference category query mode but has not yet inquired and selected the user preference subcategory tag. The service platform can then perform subsequent page updates and selection of user preference information categories based on the preference category query mode.

[0050] S104: In response to the target user's page browsing operation on the transaction service page, a reference subcategory tag set under the reference information category tag is determined through the preference category query mode, and the reference subcategory tag set is displayed on the transaction service page.

[0051] The page browsing operation is an operation of browsing page information made by the target user after performing a transaction service page through the user terminal. The user terminal generates a page browsing operation and sends the page browsing operation to the service platform. At this time, the service platform can receive the page browsing operation.

[0052] The preference category inquiry mode can also be called the KYC (Know Your Compensation) mode. The preference category inquiry mode varies according to the user's inquiry timing. The user inquiry timing can be understood as the time to determine the user's preference category (which can be an interest category or a subcategory under an interest category) through human-computer interaction inquiry. For example, it can be called the first preference category inquiry mode, the second preference category inquiry mode, and the third preference category inquiry mode. It is easy to understand that the first preference category inquiry mode can be referred to as the pre-KYC mode, the second preference category inquiry mode can be referred to as the in-process KYC mode, and the third preference category inquiry mode can be referred to as the post-KYC mode. Each KYC mode appears at different times, complementing each other and improving the user's KYC interest preference label selection.

[0053] Indicatively, by monitoring the target user's page browsing operations on the transaction service page through the preference category inquiry mode, the "reference subcategory tag set under the reference information category target signature" of this "interactive inquiry user" can be determined through the preference category inquiry mode during the page browsing process. The service platform displays the reference subcategory tag set under the reference information category target signature on the user-side transaction service page, so that users can click on the pushed reference subcategory tags during page browsing to continuously update or maintain their personal interest preference tags (also known as user preference subcategory information tags) or information preference category tags, thereby realizing a user-centered customized information recommendation service. Using this preference category inquiry mode, user intentions can be continuously tracked to maintain user information preferences and achieve accurate information recommendations. Allowing each user to have their own exclusive counter-style leading service greatly improves user satisfaction with the platform's transaction services, reflects the customization and exclusivity of the leading platform, and also helps the stable growth of transaction services.

[0054] An information category tag is a root information category divided according to information characteristics. An information category tag corresponds to one or more sub-information categories, and a sub-information category can be called an information sub-category tag.

[0055] Information subcategory tag: Each recommended information card (such as a service information card) corresponds to an attribute under a specific information category tag (which can be called a KYC category tag). Multiple information subcategory tags (which can be called KYC subcategory tags) are simultaneously attributed to a higher-level information category tag (which can be called a KYC parent category tag).

[0056] Reference information category tags (also known as KYC major category tags) are information category tags determined by the preference category query mode during user page browsing. Instead of displaying the reference information category tag directly, a collection of reference subcategory tags under the reference information category tag is displayed. The reference subcategory tag collection includes one or more reference subcategory tags. Reference information category tags can be determined based on the category tag determination rules of the preset preference category query mode. These category tag determination rules are not specified here.

[0057] S106: In response to the target user's subcategory label selection operation on the reference subcategory label set, determining at least one user preferred subcategory label.

[0058] The subcategory label selection operation refers to the selection operation made by the target user for the user's preferred subcategory label from the reference subcategory label set.

[0059] The user preference subcategory label refers to the interest information subcategory label of the target user determined based on the subcategory label selection operation.

[0060] The preference subcategory label information includes one or more user preference subcategory labels.

[0061] The information preference category tag information includes one or more information preference category tags.

[0062] Schematically, the target user browses the transaction service page through the user terminal, and the transaction service page displays a reference subcategory tag set. The target user inputs a subcategory tag selection operation for the user-preferred subcategory tag on the user terminal, and the user terminal sends the subcategory tag selection operation to the service platform. The service platform then determines at least one user-preferred subcategory tag in response to the target user's subcategory tag selection operation for the reference subcategory tag set.

[0063] Optionally, the user preference subcategory tag information may be updated based on the user preference subcategory tag, and the information preference category tag to which the user preference subcategory tag belongs may be determined, and the information preference category tag to which the user preference subcategory tag belongs may be updated into the information preference category tag information.

[0064] S108: Recall at least one preference information recommendation card based on the user preference subcategory tag, and update the transaction service page with recommendation information based on the preference information recommendation card.

[0065] In a specific implementation scenario, when the target user browses the user transaction page on a daily basis, the in-process KYC mode or the post-KYC mode in the preference category inquiry mode will be triggered. The information category labels (information category labels and information subcategory labels under the information category labels) will be scored and sorted through the algorithm system of the service platform, and the KYC subcategory labels under the KYC major category labels that the target user has not selected will be decided. These will be presented to the target user through the in-process KYC mode or the post-KYC mode in the preference category inquiry mode. At the same time, after the target user enters the subcategory label selection operation, the user's preferred subcategory label will be immediately determined, and the preference information recommendation card corresponding to the user's preference subcategory label will be recalled. Based on the preference information recommendation card, the display order of the information recommendation card in the transaction service page will be adjusted to complete the update of the recommended information.

[0066] In one or more embodiments of the present specification, the service platform adopts a preference category inquiry mode to determine the target user's information preference category tag information, determines an information recommendation card based on the information preference category tag information, generates a transaction service page containing the information recommendation card, and responds to the target user's page browsing operation. The reference subcategory tag set under the reference information category tag is determined through the preference category inquiry mode, and the reference subcategory tag set is displayed on the transaction service page. In response to the target user's subcategory tag selection operation for the reference subcategory tag set, the user's preference subcategory tag is determined, and the preference information recommendation card is recalled based on the user's preference subcategory tag to update the transaction service page with recommended information, thereby realizing a user-centered customized information recommendation service. Using this preference category inquiry mode, the user's intention can be continuously tracked to maintain the user's information preferences, realize accurate information recommendation, greatly improve the user's satisfaction with the platform's transaction services, reflect the customization and exclusivity of the leading platform, and also help the transaction service to grow steadily.

[0067] Please refer to Figure 4, which is a flowchart of another embodiment of an information recommendation method proposed in one or more embodiments of this specification, which specifically includes the following steps.

[0068] S202: In response to the target user's initial opening operation on the transaction service page, starting a first preference category inquiry mode for the target user, and determining a preference category inquiry area on the transaction service page through the first preference category inquiry mode.

[0069] According to some embodiments, the first preference category inquiry mode can be referred to as the pre-KYC mode. In the pre-KYC mode, when a user enters the transaction service page for the first time, a recommended reference information category label is displayed in the preference category inquiry area of ​​the transaction service page. The reference information category label is also the KYC category label form (the user can check it).

[0070] Illustratively, when configuring the first preference category inquiry mode, a preference category inquiry area may be set for the transaction service page. The preference category inquiry area is used to determine the user's preference category - KYC category - through human-computer interaction inquiry.

[0071] S204: Displaying at least one reference information category tag in the preference category inquiry area, and determining information preference category tag information of the target user in response to a category tag selection operation performed by the target user on the reference information category tag.

[0072] Exemplarily, as shown in Figure 5, Figure 5 is an interface diagram of a preference category inquiry mode. As shown in Figure 5, taking the transaction service page as the financial transaction service page as an example, the user enters the financial transaction service page for the first time to start the first preference category inquiry mode (pre-KYC mode) for the target user. The first preference category inquiry mode is associated with a preference category inquiry area on the transaction service page. In the preference category inquiry area, the user and the target user conduct interactive inquiries about preference categories. The preference category inquiry area can display user-selectable KYC category labels (that is, reference information category labels). As shown in Figure 5, the preference category inquiry area displays "Selecting good financial products", "Interpreting market trends", "Customized configuration plans", "Self-selected holding suggestions", "Receiving exciting benefits", "Selected popular content" and so on.

[0073] The target user can select one or more information preference category tags from the several reference information category tags provided. One or more information preference category tags constitute the information preference category tag information. Subsequently, when the target user uses the user terminal to browse the transaction service page of the service platform, only the kyc category tag floors that the user has selected as of interest will be displayed.

[0074] S206: Determine at least one information recommendation card for the target user based on the information preference category tag information.

[0075] Exemplarily, as shown in Figure 6, the figure is a schematic diagram of the processing scenario of the first preference category inquiry mode. The user enters the transaction service page for the first time to start the first preference category inquiry mode for the target user, providing the user with a reference information category tag to select. Subsequently, when the user browses the transaction service page, he checks the kyc category tag option in the prior kyc mode and determines the information preference category tag information including one or more kyc category tag options; at this time, the service platform will save and record the information preference category tag information (the user kyc category tag preference information shown in Figure 6), and determine at least one information recommendation card for the target user based on the information preference category tag information.

[0076] The recommendation system of the service platform uses an information recommendation algorithm to score the "service supply information card" to obtain a card recommendation score, and then recommends and sorts the "service supply information card" as a whole based on the card recommendation score, and then recalls these "service supply information cards" (the service supply information card contains transaction service information to recommend it to users for reference). The "service supply information card" is the initial information card preliminarily determined by the platform using the information recommendation algorithm; then the "service supply information card" is subjected to a rough algorithm intervention, that is, the information recommendation algorithm is called to score and sort the information category tags through the algorithm, and the priority order of the information category tags between each information category tag is arranged. At this time, the information preference category tag has the highest priority, and then the initial information card is allocated under each information category tag.

[0077] Furthermore, the initial information cards under each information category tag are sorted and intervened: the preference category tag information is queried from the DB (database), and the information recommendation cards of interest in the initial information cards are filtered out according to the user preference subcategory tags in the preference category tag selected by the user. The rest are ordinary system recommendation cards.

[0078] S208: Loading the information preference category area and the information recommendation card area on the transaction service page, displaying the information preference category tags in the information preference category tag information in the information preference category area, and displaying the information recommendation card in the information recommendation card area.

[0079] For example, at this time, the initial information cards are divided into information recommendation cards of interest and general system recommendation cards based on the information preference category tag information. The transaction service page can configure the information preference category area and the information recommendation card area; one or more information preference category tags in the information preference category tag information are displayed in the information preference category area, and the information recommendation card is displayed in the information recommendation card area.

[0080] Optionally, the information recommendation card area may set the information recommendation cards corresponding to the information preference category tags to be displayed in columns, and allocate the initial information cards to the sub-card areas corresponding to the information category tags in the information recommendation card area.

[0081] Optionally, the priority of the information recommendation cards signed by one or more information-type targets is then increased, so that the priority of the information recommendation cards signed by information-type targets is higher than that of ordinary system recommendation cards. Ordinary system recommendation cards are ranked after the information recommendation cards according to the card recommendation score. After completing the above operations, other information data of the information cards are finally assembled to complete the update of the transaction service page, and the updated transaction service page is returned to the user terminal used by the target user.

[0082] S210: In response to the target user's category tag modification operation on the information preference category tag in the information preference category area, determining to modify the information preference category tag, and updating the information preference category tag information based on the modified information preference category tag.

[0083] Specifically, as shown in FIG6 , when the target user enters the page for the second time and browses the page, he or she can also modify the information preference category label (which can be called the kyc category label floor) that he or she wants to display according to his or her preferences. Specifically, in response to the target user's category label modification operation on the information preference category label in the information preference category area, the information preference category label is determined to be modified, and the information preference category label information is updated based on the modified information preference category label.

[0084] For example, during daily page browsing, if a user is dissatisfied with the information preference category tag (kyc major interest preference tag) initially selected and wants to modify (add or delete) the kyc tag, they can select the kyc category tab list option and re-select the kyc personal interest preference tag by modifying the kyc category tab list. That is, the target user triggers a category tag modification operation for the information preference category tag based on the information preference category list option in the information preference category area, determines to modify the information preference category tag, and updates the information preference category tag information based on the modified information preference category tag.

[0085] S212: In response to the target user's target card operation on the reference information recommendation card in the transaction service page, determine the reference information subcategory label corresponding to the reference information recommendation card, determine that the reference information subcategory label is a non-user preference type, and delete the reference information subcategory label in the information preference category label information based on the non-user preference type.

[0086] Reference information recommendation cards can be understood as information recommendation cards that the target user is not interested in.

[0087] The target card operation can be understood as the target user's lack of interest in the reference information recommendation card. At this time, the service platform can confirm the reference information subcategory label corresponding to the reference information recommendation card, determine that the reference information subcategory label is a non-user preference type, and delete the reference information subcategory label in the information preference category label information based on the non-user preference type.

[0088] In one or more embodiments of the present specification, a service platform utilizes a preference category query mode to determine information preference category tag information corresponding to a target user's initial opening operation, determines information recommendation cards based on the information preference category tag information to generate a transaction service page, determines a reference subcategory tag set under the reference information category tag through the preference category query mode after the target user enters a page browsing operation, displays the reference subcategory tag set on the transaction service page, determines the user's preferred subcategory tag in response to the target user's selection of a subcategory tag within the reference subcategory tag set, recalls a preference information recommendation card based on the user's preferred subcategory tag, and updates the transaction service page with recommended information, and guides the target user through category tag modification operations and target card operations through the preference category query mode, thereby implementing a user-centric, customized information recommendation service. This preference category query mode continuously tracks user intent to maintain user information preferences and achieve accurate information recommendations. This allows each user to have their own dedicated counter-style guidance service, significantly improving user satisfaction with the platform's transaction services, embodying the customization and exclusivity of the guidance platform, and also contributing to the stable growth of transaction services.

[0089] Please refer to Figure 7, which is a flowchart of another embodiment of an information recommendation method proposed in one or more embodiments of this specification, which specifically includes the following steps.

[0090] S302: Displaying a transaction service page including the information recommendation card.

[0091] For details, please refer to the method steps in other embodiments of this specification, which will not be repeated here.

[0092] S304: Start a second preference category inquiry mode for the target user, determine a first subcategory tag set under a first information category target tag, and display the first subcategory tag set on the transaction service page. The first information category tag is different from the information preference category tag in the information preference category area.

[0093] According to some embodiments, the second preference category inquiry mode can be referred to as the in-process KYC mode. In the in-process KYC mode, when a user is not browsing the transaction service page for the first time, the first subcategory tag set under the first information category tag is displayed on the transaction service page. The first information category tag is different from the information preference category tag in the information preference category area. It can be understood that the second preference category inquiry mode displays the first subcategory tag set under the KYC major category (that is, the information preference category tag) that does not belong to the user's preference (not clicked to select). The first subcategory tag set can be displayed in the form of a KYC subcategory tag form.

[0094] The in-process kcy mode will only display the kyc subcategory tags under the unselected kyc major category tags. The in-process kcy mode helps recommend users more potential kyc subcategory tags (that is, the first subcategory tags) that may be of interest. Once the user checks the kyc subcategory tags under the unpreferred kyc major category tags for the first subcategory tag set, the checked kyc subcategory tags under the unpreferred kyc major category tags will now be used as the user's preferred subcategory tags.

[0095] Update the user preference subcategory tag information based on the user preference subcategory tag, and update the information preference category tag information based on the information category tag corresponding to the user preference subcategory tag. It can be understood that the kyc subcategory tag and the kyc category tag to which the kyc subcategory tag belongs will be saved and recorded by the platform, and the subsequent extensible transaction service page will immediately present the user with the information card associated with the kyc subcategory tag.

[0096] S306: Start the third preference category inquiry mode for the target user, determine the second subcategory tag set under the information preference category target signature, and display the second subcategory tag set on the transaction service page, wherein the second subcategory tag set includes at least one information preference subcategory tag that is not selected by the target user.

[0097] According to some embodiments, the third preference category inquiry mode can be referred to as the post-KYC mode. In the post-KYC mode, when the user is not browsing the transaction service page for the first time, the second subcategory tag set under the information preference category tag is displayed on the transaction service page; it can be understood that in the pre-KYC mode, the user only selected the information preference category tag, and for the sake of efficient and convenient information recommendation, no detailed inquiry was made on the subcategory tags under the information preference category tag.

[0098] The third preference category inquiry mode displays the second subcategory tag set under the KYC category (that is, the information preference category tag) that belongs to the user's preference (not clicked to select). The second subcategory tag set can be displayed in the form of a KYC subcategory tag form; the third preference category inquiry mode is to help users determine the KYC subcategory tag set under the known preferred KYC category tag, and ensure that each time the platform recalls the recommended card, it gives priority to the user's preferences and favorite KYC subcategory tag attributes.

[0099] For example, as shown in Figure 8, Figure 8 is a scenario diagram of a preference category inquiry mode provided in this specification. If the target user is not browsing the transaction service page for the first time, one way may be to display the first subcategory tag set under the first information category target label in the transaction service page. The first information category target label is different from the information preference category target label in the information preference category area. It can be understood that the second preference category inquiry mode displays the first subcategory tag set under the KYC category (that is, the information preference category label) that does not belong to the user's preference (not clicked to select). One way may be to display the second subcategory tag set under the information preference category target label in the transaction service page.

[0100] The target user selects one or more target KYC subcategory label options of the first / second subcategory label set recommended by the in-process KYC model. The target KYC subcategory label option is then used as the user's preferred subcategory label. The service platform saves or modifies the user's preferred subcategory label information, and can also modify the information preference category label information.

[0101] S308: In response to the target user's subcategory tag selection operation for the reference subcategory tag set, determine at least one user preference subcategory tag, recall at least one preference information recommendation card based on the user preference subcategory tag, and update the transaction service page with recommendation information based on the preference information recommendation card.

[0102] The user preference subcategory label information and the information preference category label information are updated based on the user preference subcategory label, and the reference subcategory label set includes at least one of a first subcategory label set and a second subcategory label set.

[0103] In a specific implementation scenario, when the target user browses the user transaction page on a daily basis, the in-process KYC mode or the post-KYC mode in the preference category inquiry mode is triggered. The information category labels (information category labels and information subcategory labels under the information category labels) are scored and sorted through the algorithm system of the service platform, and the KYC subcategory labels under the KYC category labels that the target user has not selected are determined. After the target user enters the subcategory label selection operation, the user's preference subcategory label is immediately determined, and the preference subcategory label information is updated. The service information card of the transaction service page is recalled, and based on the preference subcategory label information, it is determined whether the service information card has a preference subcategory label, that is, user preference information cards and non-user preference information cards are filtered out.

[0104] Before arranging and configuring the user preference information card to the non-user preference information card in the transaction service page, the "personal preference card corresponding to the user preference subcategory label" can be immediately pinned to increase the priority. Specifically, the user preference information card can be multiple and each user preference information card corresponds to a different subcategory preference label. The user preference information cards are arranged according to the preference label recording date of the subcategory preference label corresponding to the user preference information card to obtain a user preference information card sequence, and the user preference information card sequence is pinned to increase the priority (first sorting process); at the same time, for the non-user preference information card, the original information recommendation algorithm is used to determine the information recommendation score of the non-user preference information card, and the multiple non-user preference information cards are sorted according to the information recommendation score to obtain a non-user preference information card sequence (second sorting process), and the non-user preference information card sequence is arranged after the user preference information card sequence, thereby completing the page update process of the transaction service page after the user enters the subcategory label selection operation.

[0105] In a feasible implementation, after determining at least one user preference subcategory label, the service platform may perform the following method.

[0106] A2: The service platform writes the user's preference subcategory tag into the preference subcategory tag information.

[0107] A4: The service platform determines the target information category tag corresponding to the user preference subcategory tag. If the target information category tag does not exist in the information preference category tag information, the target information category tag is written into the information preference category tag information.

[0108] The above process completes the process of pairing preference subcategory label information and information preference category label information based on user preference subcategory labels.

[0109] S310: In response to the target user's page refresh operation on the transaction service page, the service information cards in the transaction service page are recalled, the user preference information cards and the non-user preference information cards are determined based on the preference subcategory label information, the user preference information cards are arranged before the non-user preference information cards in the transaction service page, and the user preference information cards are first sorted in the transaction service page based on the preference label recording date and the non-user preference information cards are second sorted in the transaction service page based on the information recommendation points.

[0110] The second preference category inquiry mode and the third preference category inquiry mode both support page refresh logic. After browsing the transaction service page, the target user is not satisfied with the service information card recommended by the transaction service page. The target user can input a page refresh operation for the transaction service page on the user end and send it to the service platform. As shown in FIG8 , the service platform responds to the target user's page refresh operation for the transaction service page, recalls the service information cards in the transaction service page, determines the user preference information card and the non-user preference information card based on the preference subcategory label information, arranges the user preference information card before the non-user preference information card in the transaction service page, and performs a first sorting process on the user preference information card in the transaction service page based on the preference label recording date and a second sorting process on the non-user preference information card in the transaction service page based on the information recommendation score.

[0111] Specifically, after the page refresh operation, the service platform recalls the service information card of the transaction service page, queries the preference subcategory tag information to determine whether the service information card has a preference subcategory tag, that is, filters out the user preference information cards and non-user preference information cards on the page.

[0112] Before arranging and configuring the user preference information card to the non-user preference information card in the transaction service page, the "personal preference card corresponding to the user preference subcategory label" can be immediately pinned to increase the priority. Specifically, the user preference information card can be multiple, and each user preference information card corresponds to a different subcategory preference label. The user preference information cards are arranged according to the preference label recording date of the subcategory preference label corresponding to the user preference information card to obtain a user preference information card sequence, and the user preference information card sequence is pinned to increase the priority (first sorting process); at the same time, for the non-user preference information card, the original information recommendation algorithm is used to determine the information recommendation score of the non-user preference information card, and the multiple non-user preference information cards are sorted according to the information recommendation score to obtain a non-user preference information card sequence (second sorting process), and the non-user preference information card sequence is arranged after the user preference information card sequence, thereby completing the page update process of the transaction service page after the user inputs the page refresh operation.

[0113] In one or more embodiments of the present specification, the service platform uses a first preference category query mode to determine the information preference category tag information corresponding to the target user's initial opening operation, determines an information recommendation card based on the information preference category tag information to generate a transaction service page, and after the target user enters a page browsing operation, uses a second or third preference category query mode to determine a reference subcategory tag set under the reference information category tag, and displays the reference subcategory tag set on the transaction service page. In response to the target user's subcategory tag selection operation for the reference subcategory tag set, the user's preferred subcategory tag is determined, and the preference information recommendation card is recalled based on the user's preferred subcategory tag to update the transaction service page with recommended information. This can implement a user-centric customized information recommendation service. Using this preference category query mode, user intentions can be continuously tracked to maintain user preference tags, thereby achieving accurate information recommendations. This allows each user to have their own exclusive counter-style leading service, significantly improving user satisfaction with the platform's transaction services, reflecting the customization and exclusivity of the leading platform, and also promoting the stable growth of transaction services.

[0114] Please refer to Figure 9, which is a flowchart of another embodiment of an information recommendation method proposed in one or more embodiments of this specification, which specifically includes the following steps.

[0115] S402: In response to the target user's subcategory label selection operation for the reference subcategory label set, determining at least one user preferred subcategory label.

[0116] Optionally, in response to the target user's target card operation on the reference information recommendation card in the transaction service page, the reference information subcategory label corresponding to the reference information recommendation card is determined, the reference information subcategory label is determined to be a non-user preference type, and if the reference information subcategory label is a preference subcategory label, the preference subcategory label status is set to a preference subcategory label invalid state.

[0117] S404: configuring a preference tag validity period for the user preference subcategory tag, and performing preference subcategory tag management on the user preference subcategory tag within the preference tag validity period.

[0118] In this specification, after determining the user's preferred subcategory tag according to the target user's subcategory tag selection operation, the user's preferred subcategory tag is configured with a preference tag validity period, and subsequently the preference subcategory tag is managed based on the preference tag validity period.

[0119] Information subcategory tags within the validity period of the preference tag can be considered as valid preference subcategory tags, and kyc subcategory tags outside the validity period of the preference tag can be considered as invalid preference subcategory tags.

[0120] Optionally, to adapt to changes in users' preferred kyc subcategory tags over time, a continuous positive / negative feedback mechanism can be configured for the kyc subcategory tags, as shown in Figure 10, which is a schematic diagram of a feedback mechanism for a preference category query mode. For example, the following approach can be used.

[0121] B2: Based on the detection, the preference subcategory label status corresponding to the user preference subcategory label is determined.

[0122] The preference subcategory label status includes a preference subcategory label valid status and a preference subcategory label invalid status.

[0123] As shown in FIG10 , the validity period of the preference tag is indicated as the shelf life in FIG10 . Assuming that the validity period of the preference tag is x days, further verification is performed; within the shelf life of x days, the preference subcategory tag status is the preference subcategory tag valid status, and after the shelf life of x days, the preference subcategory tag status is the preference subcategory tag invalid status.

[0124] B4: If the preference subcategory tag status is the preference subcategory tag valid status, priority information recommendation processing is performed on the preference information recommendation card corresponding to the user preference subcategory tag, and the preference category inquiry mode for the target user is started, and the recommended preference subcategory tag set associated with the user preference subcategory tag is recommended to the target user, and the recommended preference subcategory tag set is used as the reference subcategory tag set and the step of displaying the reference subcategory tag set on the transaction service page is executed.

[0125] Positive feedback mechanism: After the user clicks to select the kyc subcategory label as the preference label, a preference label validity period of x days will be set (the shelf life in Figure 10). During the shelf life, the preference information recommendation card corresponding to the user preference subcategory label will be given priority information recommendation processing. For example, the kyc subcategory label card selected by the user will be strongly top-placed, and at the same time, the recommended preference subcategory label set associated with the user preference subcategory label (kyc subcategory label) will be recommended to provide the user with more choices. That is, the recommended preference subcategory label set is used as the reference subcategory label set and the step of displaying the reference subcategory label set on the transaction service page is executed.

[0126] Furthermore, after the validity period of the preference tag has expired, the kyc subcategory tag in the reference subcategory tag set can be used through the preference category query mode. If the user clicks on the kyc subcategory tag information card, it will be considered that the user is interested in the kyc subcategory tag, and the kyc information card under the kyc subcategory tag will continue to be pinned to the top.

[0127] B6: If the preference subcategory tag status is the preference subcategory tag invalid state, the information card operation frequency of the target user on the preference information recommendation card corresponding to the user preference subcategory tag is monitored within a preset period, and the preference subcategory tag status extension management is performed on the user preference subcategory tag based on the information card operation frequency.

[0128] Negative feedback mechanism: After the user's preferred kyc subcategory tag has expired, the status of the preferred subcategory tag is invalid. If the user has operated the information card of the kyc subcategory tag under the preferred kyc subcategory tag displayed by the service platform less frequently, the service platform will determine that the user is not interested in the kyc subcategory tag and reset the kyc classification tag to a regular subcategory tag. At the same time, the kyc subcategory tag can appear on the user's browsing page for the user to reselect. In addition, when browsing the page, the user can actively press and hold the information card displayed at that time and click the "Not Interested" button that pops up to ensure that the user will not receive information cards with the kyc subcategory tag attributes in the future.

[0129] Optionally, the preference subcategory tag status extension management of the user preference subcategory tag based on the information card operation frequency may be performed in the following manner.

[0130] 1. If the operation frequency of the information card is greater than the operation frequency threshold, the preference subcategory tag state of the user preference subcategory tag is extended.

[0131] The operation frequency threshold is the threshold for the frequency of information card operations.

[0132] 2. If the operation frequency of the information card is less than or equal to the operation frequency threshold, the preference subcategory tag state of the user preference subcategory tag is set to the regular subcategory tag state, and the regular subcategory tag in the regular subcategory tag state is added to the reference subcategory tag set.

[0133] If the frequency of operating the information card of the kyc subcategory tag under the preferred kyc subcategory tag displayed by the service platform is always low, the service platform determines that the user is not interested in the kyc subcategory tag, and resets the kyc classification tag to the normal state, and adds the regular subcategory tag in the regular subcategory tag state to the reference subcategory tag set. At this time, the kyc subcategory tag can appear in the user's browsing page for the user to reselect.

[0134] In one or more embodiments of the present specification, a service platform utilizes a first preference category query mode to determine information preference category tag information corresponding to a target user's initial opening operation, determines information recommendation cards based on the information preference category tag information to generate a transaction service page, and after the target user enters a page browsing operation, utilizes a second or third preference category query mode to determine a reference subcategory tag set under the reference information category tag and displays the reference subcategory tag set on the transaction service page. In response to the target user selecting a subcategory tag within the reference subcategory tag set, the user's preferred subcategory tag is determined, and preference information recommendation cards are recalled based on the user's preferred subcategory tag to update the transaction service page with recommended information. This enables a user-centric, customized information recommendation service. This preference category query mode and the corresponding positive and negative feedback mechanism continuously track user intent to maintain user preference tags and achieve accurate information recommendations. This allows each user to have their own exclusive counter-style leading service, significantly improving user satisfaction with the platform's transaction services, embodying the customized and exclusive nature of the leading platform, and contributing to the stable growth of transaction services.
