Description

Technical Field

[0001] The present invention relates to the field of Internet technology, and in particular to a method, device and system for recommending information. Background Art

[0002] The user needs to authorize the first server to read the mobile phone number in the address book. The first server obtains the mobile phone number from the terminal used by the user, obtains the historical behavior information of the owner of the mobile phone number from the second server based on the mobile phone number, and recommends the historical behavior information of the owner of the mobile phone number to the user.

[0003] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:

[0004] Users are paying more and more attention to their privacy (i.e., the mobile phone numbers in the user's address book), so fewer and fewer users choose to authorize. Without the user's authorization, information cannot be recommended to the user, resulting in limited information recommendation. Summary of the invention

[0082] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0083] It should be pointed out that the embodiments of the present invention and the features in the embodiments may be combined with each other if there is no conflict.

[0084] The prior art not only has the problems mentioned in the background technology, but also has the following problems:

[0085] The relationship between the owner of the mobile phone number and the user is not necessarily very close. For example, the owner of the mobile phone number is a real estate salesperson. The user takes a flyer for the real estate and learns the mobile phone number of the real estate salesperson through the flyer and stores it, but the owner of the mobile phone number does not know the user. There are many similar situations, which are not listed here. Due to the loose relationship, the appreciation level and taste of the owner of the mobile phone number and the user are different, resulting in a low success rate of information recommendation.

[0086] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a method for recommending information, which is applied to a first server, such as Figure 1 As shown, the method includes:

[0087] Step S101: Receive a first identifier and a second identifier sent by at least one second terminal, and create a mapping relationship between the first identifier and at least one second identifier according to the first identifier and the second identifier.

[0088] In this step, it should be noted that the first terminal is the terminal that sends the shared information, and the second terminal is the terminal used by the user to browse the shared information. Since the user browsing the shared information may be one or more, the first server can receive the first identifier and the second identifier sent by at least one second terminal.

[0089] Step S102: acquiring historical behavior information of the user corresponding to the first identifier and historical behavior information of the users corresponding to each of the second identifiers according to the mapping relationship, and processing the acquired historical behavior information to obtain target information.

[0090] In this step, it should be noted that the user's historical behavior information may include news information viewed by the user, video information viewed by the user, picture information viewed by the user, or product information purchased by the user.

[0091] Step S103: Send the target information to the first terminal.

[0092] In this step, when implemented specifically, the target information may be sent to the first terminal via a web page, email, or text message.

[0093] In this embodiment, the first server obtains the target information using the first identifier and the second identifier instead of the mobile phone number. The recommended information does not require obtaining the mobile phone number in the user's address book, thereby reducing the problem of being unable to recommend information due to user privacy protection and expanding the scope of application of information recommendation.

[0094] In the embodiment of the present invention, the first identifier sent by the second terminal is obtained by parsing the shared information sent by the first terminal when the second terminal detects an instruction to browse the shared information;

[0095] The second identifier sent by the second terminal is generated by the second terminal according to information input by the user of the second terminal on the sharing page, and the sharing page is obtained according to sharing page information, and the sharing page information is obtained by parsing the sharing information.

[0096] It should be noted that this embodiment Figure 2 The embodiment shown has been described in detail and will not be described in detail here.

[0097] In this embodiment, the shared information is parsed to obtain a first identifier, and the information entered by the second terminal user on the sharing page generates a second identifier. The method for obtaining the first identifier and the second identifier is simple, so that the first server obtains the target information using the first identifier and the second identifier instead of the mobile phone number. The recommended information does not require the mobile phone number in the user's address book, which further reduces the problem of being unable to recommend information due to user privacy protection and further expands the scope of application of information recommendation.

[0098] In the embodiment of the present invention, creating a mapping relationship between the first identifier and at least one of the second identifiers according to the first identifier and the second identifier includes:

[0099] According to the first identifier and the second identifier, obtaining information on the degree of interaction between a user corresponding to the first identifier and a user corresponding to the second identifier, and creating a mapping relationship between the first identifier and at least one of the second identifiers based on the interaction degree information;

[0100] Alternatively, a mapping relationship between the first identifier and at least one of the second identifiers is created using a six-degree-of-space algorithm based on the first identifier and the second identifier.

[0101] In this embodiment, a specific example is used below to illustrate how to obtain the interaction degree information between the user corresponding to the first identifier and the user corresponding to the second identifier according to the first identifier and the second identifier, and create a mapping relationship between the first identifier and at least one of the second identifiers based on the interaction degree information: obtain the interaction degree relationship between the user corresponding to the first identifier and the user corresponding to the second identifier from the second server according to the first identifier and the second identifier, create a first-layer mapping relationship according to the first identifier and the second identifier of the two-party interaction, create a second-layer mapping relationship according to the first identifier and the second identifier of the one-party interaction at least twice, and create a third-layer mapping relationship according to the first identifier and the second identifier of the one-party interaction once. Give an example to illustrate the two-party interaction and the one-party interaction: the first terminal sends sharing information, and the second terminal user browses the sharing information; the second terminal sends sharing information, and the first terminal user browses the sharing information, which is the two-party interaction. The first terminal sends sharing information, and the second terminal user browses the sharing information; the second terminal sends sharing information, and the first terminal user does not browse the sharing information, which is the one-party interaction.

[0102] It should be understood that the creation of a mapping relationship is not limited to the examples given in the present invention. Without affecting the embodiments of the present invention, those skilled in the art can flexibly create a mapping relationship (including setting the number of layers of the mapping relationship and the method of creating each layer, etc.). For example, a mapping relationship between a first identifier and at least one second identifier is created based on the first identifier and the second identifier using the existing six-degree-of-space algorithm.

[0103] In this embodiment, a mapping relationship is created based on the interaction degree information. In the mapping relationship, the relationship between the user corresponding to the first identifier and the user corresponding to the second identifier is closer. The target information is obtained through the mapping relationship. The target information is more in line with the appreciation level and taste of the user corresponding to the first identifier, thereby improving the success rate of information recommendation.

[0104] In the embodiment of the present invention, step S102 may include:

[0105] According to the first identifier in the mapping relationship, the historical behavior information of the user corresponding to the first identifier is obtained, and according to each of the second identifiers in the mapping relationship, the historical behavior information of the user corresponding to each of the second identifiers is obtained;

[0106] Using a collaborative filtering algorithm to calculate the historical behavior information of the user corresponding to the first identifier and the historical behavior information of the users corresponding to each of the second identifiers, respectively, to obtain the preference of the user corresponding to the first identifier and the preference of the users corresponding to each of the second identifiers;

[0107] The historical behavior information of the user corresponding to the second identifier having the same preference as the user corresponding to the first identifier is used as the target information.

[0108] It should be noted that the specific implementation of this embodiment is different from Figure 4 The implementation methods of the illustrated embodiments are the same and will not be described again herein.

[0109] In this embodiment, compared with the prior art, the present invention uses the historical behavior information of the user corresponding to the second identifier who has the same preference as the user corresponding to the first identifier as the target information, rather than using the historical behavior information of the owners of all mobile phone numbers as the target information. The target information is more in line with the appreciation level and taste of the user corresponding to the first identifier, further improving the success rate of information recommendation.

[0110] In order to solve the problems existing in the prior art, another embodiment of the present invention provides a method for recommending information, which is applied to a second terminal, such as Figure 2 As shown, the method includes:

[0111] Step S201: receiving sharing information sent by a first terminal.

[0112] In this step, during specific implementation, the shared information is assembled by the first terminal using existing assembly technology to assemble the shared page information and the first identifier.

[0113] Step S202: Obtain a first identifier and a second identifier according to the sharing information.

[0114] Step S203: Send the first identifier and the second identifier to the first server;

[0115] The first server obtains historical behavior information of the user corresponding to the first identifier according to the first identifier, and obtains historical behavior information of the user corresponding to the second identifier according to the second identifier, thereby obtaining target information, and sending the target information to the first terminal.

[0116] In this embodiment, during specific implementation, the user corresponding to the first identifier includes the first terminal user, and the user corresponding to the second identifier includes the second terminal user. The first identifier is different from the second identifier, and thus, the user corresponding to the first identifier is different from the user corresponding to the second identifier. The first terminal and the second terminal may be the same or different.

[0117] like Figure 3As shown, terminal one sends a sharing link (i.e., sharing information) to terminal two, terminal three, terminal four, and terminal five. Since only terminal two and terminal three users browse the sharing link, terminal two obtains the identifier of terminal one user and the identifier of terminal two user according to the sharing link, and sends them to the first server; terminal three obtains the identifier of terminal one user and the identifier of terminal three user according to the sharing link, and sends them to the first server. The first server matches the identifier of terminal one user, the identifier of terminal two user, and the identifier of terminal three user and saves them in the terminal one user relationship pool, which is set on the first server. The identifier of terminal one user is the first identifier, the identifier of terminal two user and the identifier of terminal three user are both the second identifier, and the identifier of terminal one user, the identifier of terminal two user, and the identifier of terminal three user are the mapping relationship between the first identifier and at least one second identifier.

[0118] In this embodiment, sharing information sent by the first terminal is received, a first identifier and a second identifier are obtained based on the sharing information, and the first identifier and the second identifier are sent to the first server, so that the first server obtains the target information using the first identifier and the second identifier instead of the mobile phone number. The recommended information does not require obtaining the mobile phone number in the user's address book, which reduces the problem of being unable to recommend information due to user privacy protection and expands the scope of application of information recommendation.

[0119] In the embodiment of the present invention, step S202 may include:

[0120] If an instruction to browse the shared information is detected, the shared information is parsed to obtain a first identifier and shared page information;

[0121] Displaying the sharing page to the second terminal user according to the sharing page information;

[0122] A second identifier is generated according to the information input by the second terminal user on the sharing page.

[0123] In this embodiment, the following may be performed first: if an instruction to browse the shared information is detected, the shared information is parsed to obtain a first identifier and shared page information; then the following may be performed: displaying the shared page to the second terminal user according to the shared page information; then the following may be performed: generating a second identifier according to the information input by the second terminal user on the shared page; and finally the following may be performed: sending the first identifier and the second identifier to the first server. It should be understood that the object performing the above operations may be the browser of the second terminal.

[0124] In this embodiment, the method of obtaining the first identifier and the second identifier is simple, so that the first server obtains the target information using the first identifier and the second identifier instead of the mobile phone number. The recommended information does not need to obtain the mobile phone number in the user's address book, further reducing the problem of being unable to recommend information due to user privacy protection, and further expanding the scope of application of information recommendation.

[0125] In the embodiment of the present invention, the information input by the second terminal user on the sharing page includes an ID assigned to the second terminal user by the second server;

[0126] The sharing information includes a sharing link or a calling app protocol.

[0127] In this embodiment, the types of shared information are diverse, which increases the probability of obtaining the first identification and the second identification, and further expands the scope of application of information recommendation.

[0128] In order to solve the problems existing in the prior art, another embodiment of the present invention provides a method for recommending information, such as Figure 4 As shown, the method includes:

[0129] Step S401: The first terminal generates sharing information and sends the sharing information to the second terminal.

[0130] In this step, during the specific implementation, the first terminal obtains the corresponding sharing page information from the second server according to the news information, video information or picture information browsed by the first terminal user, assembles the corresponding sharing page information and the identifier of the first terminal user (the identifier of the first terminal user is the first identifier) ​​into sharing information, and sends the sharing information to the second terminal. In addition, the identifier of the first terminal user includes: the ID assigned to the first terminal user by the second server. When the first terminal user visits the second server for the first time, it is necessary to send registration information to the second server, and the second server assigns the ID of the first terminal user (unique) to the first terminal user according to the registration information; when the first terminal user visits the second server in the future, it is necessary to provide the ID of the first terminal user to the second server. Furthermore, the sharing information can be a sharing link or a call app protocol (also known as a schema protocol).

[0131] The following is a specific example to illustrate this step: when there are special promotions, likes collection or group purchase activities, the first terminal generates sharing information based on the relevant goods or promotion information. The first terminal publishes the sharing information in the circle of friends through social software or directly sends it to the second terminal. The first terminal generates sharing information based on the relevant goods or promotion information, which may include: the first terminal obtains the corresponding sharing page information from the second server (the second server may be an e-commerce server) based on the relevant goods or promotion information, and assembles the corresponding sharing page information and the identifier of the first terminal user into sharing information using the existing assembly method.

[0132] Step S402: The second terminal receives the sharing information, and if an instruction to browse the sharing information is detected, the sharing information is parsed to obtain the first identifier and sharing page information.

[0133] In this step, when the second terminal user is interested in the shared information or has a close relationship with the first terminal user and is willing to help the first terminal user achieve the goal, he will want to browse the shared information, so the second terminal can monitor the instruction to browse the shared information. It should be noted that since the second terminal user is a user who is interested in the shared information or has a close relationship with the first terminal user, the appreciation level and taste of the second terminal user and the first terminal user are the same or similar, and the success rate of recommendation will be improved.

[0134] like Figure 5 As shown, the following is a specific example to illustrate this step: the shared information includes xxxx.com / ? a=xxx&b=xxx&userid=00001, and it is agreed in advance that userid is the first identifier (i.e., the identifier of user f). If the second terminal (user a terminal) detects an instruction to browse the shared information, the shared information is parsed using the parsing method of the prior art to obtain the shared page information (i.e., xxxx.com / ? a=xxx&b=xxx) and the first identifier (the identifier of user f is 00001), and 00001 is saved to the local cache of the second terminal. The method of saving 00001 to the local cache of the user a terminal can be the WebStorage method or the cookies method. The difference between the Web Storage method and the cookies method is that the visited party of the cookies method can definitely obtain the information in the cookies of the visiting party, but the visited party of the Web Storage method may not be able to obtain the information in the Storage of the visiting party. Both methods can be used on the browser.

[0135] Web Storage method: Web Storage actually consists of two parts: sessionStorage and localStorage. SessionStorage is used to locally store data in a session. These data can only be accessed by pages in the same session and are destroyed when the session ends. Therefore, sessionStorage is not a persistent local storage, but only session-level storage. LocalStorage is used for persistent local storage. Unless the data is actively deleted, it will never expire.

[0136] Cookies method: Sometimes also used in its plural form Cookies, refers to data (usually encrypted) stored on the user's local terminal by certain websites in order to identify the user and conduct session tracking.

[0137] Step S403: The second terminal obtains display data from the second server according to the shared page information, and displays the shared page to the second terminal user according to the display data.

[0138] In this step, during specific implementation, the second terminal establishes a connection with the second server according to the shared page information, and obtains display data from the second server through the connection. The display data may be a login page.

[0139] Step S404: The second terminal generates a second identifier according to the information input by the second terminal user on the sharing page.

[0140] In this step, when implemented, the information entered by the second terminal user on the sharing page includes the ID assigned to the second terminal user by the second server. The ID assigned to the second terminal user by the second server is used as the identification of the second terminal user, and the identification of the second terminal user is the second identification. When the second terminal user visits the second server for the first time, it is necessary to send registration information to the second server, and the second server assigns the ID of the second terminal user (with uniqueness) to the second terminal user according to the registration information; when the second terminal user visits the second server in the future, it is necessary to provide the second terminal user's ID to the second server.

[0141] like Figure 5 As shown, based on the example given in step S402, this step is explained with a specific example: the information input by the second terminal user on the sharing page is the identifier of user a, the identifier of user a is used as the second identifier, and the identifier of user a is saved in the local cache of the second terminal.

[0142] If the information input by the second terminal user on the sharing page changes, the second identifier is generated according to the changed information input by the second terminal user on the sharing page, thus ensuring the real-time and validity of the second identifier in the mapping relationship.

[0143] Step S405: The second terminal sends the first identifier and the second identifier to the first server.

[0144] In this step, during specific implementation, the second terminal reads the first identifier and the second identifier from the local cache and sends them to the first server.

[0145] Step S406: The first server receives the first identifier and the second identifier sent by the at least one second terminal, and creates a mapping relationship between the first identifier and the at least one second identifier according to the first identifier and the second identifier.

[0146] In this step, it should be understood that the second identifiers sent by each second terminal can be the same or different. If the second identifiers sent are the same, deduplication processing is required to create a mapping relationship. For any first identifier, a mapping relationship between the first identifier and at least one second identifier can be created. It should be noted that the role of the first identifier in the mapping relationship is to determine the recipient of the target information-the first terminal.

[0147] The following is a specific example to illustrate this step: the second terminal includes terminal a, terminal b and terminal c; the first identifier sent by terminal a is identifier one, and the second identifier sent by terminal a is identifier two; the first identifier sent by terminal b is identifier three, and the second identifier sent by terminal b is identifier four; the first identifier sent by terminal c is identifier five, and the second identifier sent by terminal c is identifier six. Among them, identifier one and identifier three are the same, and identifier one and identifier five are different. Therefore, the first server creates a mapping relationship between the first identifier and at least one second identifier according to identifier one, identifier two and identifier four, but the first server cannot create a mapping relationship according to identifier one, identifier two, identifier five and identifier six.

[0148] Step S407: The first server obtains historical behavior information of the user corresponding to the first identifier from the second server according to the first identifier, and obtains historical behavior information of the users corresponding to each second identifier from the second server according to each second identifier.

[0149] In this step, the following Figure 1 Based on the examples given in the illustrated embodiment, this step is illustrated by a specific example: in the three-layer mapping relationship, only the user corresponding to the second identifier in the second layer mapping relationship has a close relationship with the user corresponding to the first identifier. Therefore, according to the first identifier and the second identifier in the second layer mapping relationship, the historical behavior information of the user corresponding to the first identifier and the historical behavior information of the user corresponding to the second identifier are respectively obtained from the second server.

[0150] It should be understood that the first identifier and the historical behavior information of the user corresponding to the first identifier are matched and stored in the second server, and similarly, the second identifier and the historical behavior information of the user corresponding to the second identifier are also matched and stored in the second server.

[0151] Step S408: The first server uses a collaborative filtering algorithm to calculate the historical behavior information of the user corresponding to the first identifier and the historical behavior information of the users corresponding to each of the second identifiers, to obtain the preference of the user corresponding to the first identifier and the preference of the users corresponding to each of the second identifiers.

[0152] Step S409: The first server uses the historical behavior information of the user corresponding to the second identifier having the same preference as the user corresponding to the first identifier as target information.

[0153] Step S410: The first server sends target information to the first terminal.

[0154] It should be understood that the first server can be the same server as the second server, or the first server can be a separately set server. In addition, the user corresponding to the first identifier and the user corresponding to the second identifier are both registered users of the second server, the first identifier is different from the second identifier, and the user corresponding to the first identifier is different from the user corresponding to the second identifier, but the first identifier and the second identifier do not contain the user's mobile phone number, so the method for recommending information provided in the embodiment of the present invention does not involve user privacy.

[0155] The embodiments of the present invention can be applicable to the current e-commerce model. When applied to the current marketing scenarios, it can ensure the user experience without involving user privacy (i.e., the mobile phone number in the user's address book), achieve imperceptible association with user relationships, and do not rely on user authorization, thereby reducing the problem of being unable to recommend information due to user privacy protection, and expanding the scope of application of information recommendation. The information of the goods purchased by the user corresponding to the second identifier who has the same preference as the user corresponding to the first identifier is used as the target information. The target information is more in line with the appreciation level and taste of the user corresponding to the first identifier, thereby improving the success rate of product recommendations and increasing the sales volume of recommended products.

[0156] In order to solve the problems existing in the prior art, another embodiment of the present invention provides a method for recommending information, the method comprising:
