In the description of the present application, it is noted that, unless explicitly stated or limited otherwise, "including" and "having" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art. Further, in the description of the present application, "a plurality" means two or more unless otherwise specified. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The present application will be described in detail with reference to specific examples.
In one embodiment, as shown in fig. 1, a method of recommending social users is proposed, which may be implemented by means of a computer program, and which may be run on an image source tracking device based on von neumann architecture. The computer program may be integrated into the application or may run as a separate tool-like application.
Specifically, the method for recommending social users comprises the following steps:
s101, removing the hot spot users in the first attention list of the target user to obtain a second attention list.
The target user can be understood as any user account on the social platform, and the user account can be an identifier with unique directivity, such as a device number, a mobile phone number, a user name and the like, for example, an account of the last id of the microblog, called zhang san. The social platform may be understood as a service platform having social attribute functions such as a social function, a friend function, and a text publishing function in the prior art, for example, micro blog, trembling, or soul.
The hotspot user may be understood as an account number in which the number of interactions in the social platform exceeds an interaction threshold and/or the number of focused users exceeds an attention threshold, for example, the social platform is a microblog, the number of interactions is a sum of numbers including praise, forward, and comment, the interaction threshold is 10000 for a single microblog text, the number of focused users is a sum of the number of people focusing on the user, the attention threshold is 100 ten thousands for the user, and the hotspot user may be understood as a user account number satisfying one or more of the above conditions, for example, a user account number representing celebrity.
In one embodiment, removing the hot spot users in the first interest list of the target user and obtaining the second interest list further includes: acquiring a recessive concern list and an explicit concern list of a target user based on a preset algorithm; the first concern list is a union set of an explicit concern list and a implicit concern list, the explicit concern list is a concern list of a target user displayed on the social platform, and the implicit concern list is a user set which is concerned by the target user in an indirect concern mode on the social platform.
As shown in fig. 2, an interface schematic diagram of an explicit concern list of a target user provided by the embodiment of the present application includes zhang san 201 of the target user, where the explicit concern list is all user identifiers included in a concern list 202. In other words, when the terminal device detects a trigger condition on the [ focus ] control, the focus list 202 is displayed on the display interface, and the focus list 202 is an explicit focus list.
It should be noted that when a target user pays attention to another user, it may be understood that a node representing the target user and a node representing the another user establish a unidirectional link, and the link direction is from the node of the target user to the node of the another user, and the attention mode is defined as direct attention; when the target user mentions that the frequency of a certain user-indicated pronoun in the published text exceeds an indirect attention threshold, but the target user does not establish a unidirectional link or a bidirectional link with the user-indicated pronoun, the attention mode is defined as indirect attention. The user-designated pronouns include at least one of: user name, user nickname, topic, e.g., user name: xxx, user nickname: JayChou, topic: you are my you-le #, which are the user's pronouns for the people of the entity in week xx and the account JayChou in week xx on the social platform. In other words, indirect attention may be understood that the number of times that the target user zhang refers to the user's indicator representing the entity character week xx in the publication text exceeds the indirect attention threshold, but does not directly pay attention to the account number of week xx on the social platform, and the publication text includes text data left by all target users on the social platform, such as private letters of the social users on the social platform, the comment content published in the own account, and the comment content of the comment area under the comment content of other social users.
As shown in fig. 3, a schematic flow chart for acquiring an implicit attention list of a target user according to an embodiment of the present application includes:
s301, obtaining published texts of a target user in a preset time period;
for example, the preset time period is a publication text of the target user from No. 1/2020 to No. 12/31/2020, the publication text includes text data left by all target users on the social platform, such as private letters of the social users on the social platform, comment content published in the own account, comment content of a comment area under the comment content of other social users, and the like, for example, the comment content of the target user on a microblog is: you are my you happy # drink today with the same strawberry flavor in my week.
S302, extracting user pronouns in the published text;
the user-designated pronouns include at least one of: user name, user nickname, topic. For example, the content of the speech of the target user in the microblog is as follows: and # you are my week same strawberry flavor as my you do # drinking today, wherein the topic # you are user referees for my you do # and the user nickname "my week" both being the entity person week xx and the account number JayChou of the week xx on the social platform.
The extraction algorithm in the step can adopt a natural language processing method, firstly, the part of speech segmentation and labeling are carried out on the content of the issued text, and the corresponding entity characters are matched in a preset natural language word stock based on the labeling.
S303, determining a hidden user corresponding to the user appointed pronouns based on the user appointed pronouns, and constructing a hidden concern list based on the hidden user.
The beneficial effects brought by the technical scheme provided by some embodiments of the application at least comprise: the hidden user list is constructed by extracting the hidden user from the published text of the user, and the first concern list of the target user is formed by merging the hidden user list and the explicit user list, so that the degree of mining the interest and hobbies of the target user is improved, the establishment of the concern list of the target user is perfected, and the deviation and omission caused by the follow-up matching of recommended users for the target user are avoided.
S102, acquiring a list of users to be recommended from a user database of the social platform based on the second concern list.
It should be noted that the to-be-recommended user list includes at least one to-be-recommended user, and the attention list of the to-be-recommended user includes at least one user in the second attention list.
For example, the second interest list of the third target user includes a user a, a user B, a user C, and a user D, the server of the social platform matches at least one to-be-recommended user in the user database through the second interest list, the interest list of the to-be-recommended user at least includes one or more of the user a, the user B, the user C, and the user D, for example, matches to a to-be-recommended user 1 and a to-be-recommended user 2, the interest list of the to-be-recommended user 1 includes the user a, the interest list of the to-be-recommended user 2 includes the user B and the user D, and the to-be-recommended user list is constructed based on the at least one to-be-.
It can be understood that the attention list of the user to be recommended is acquired based on the above-mentioned acquisition process of the second attention list of the target user, in other words, the attention list of the user to be recommended is also composed of a union of the explicit attention list and the implicit attention list of the user to be recommended.
S103, based on the list of the users to be recommended, calculating the recommendation weight of each user to be recommended in the list of the users to be recommended.
As shown in fig. 4, a schematic flow chart for calculating a recommendation weight provided in the embodiment of the present application includes the specific steps of:
s1031, acquiring an intersection list of the attention list of the user to be recommended and the second attention list of the target user;
as shown in fig. 6, an intersection schematic diagram of attention lists of a target user and a user to be recommended provided in an embodiment of the present application is shown, where a second attention list of a third target user includes a user a, a user B, a user C, and a user D, a server of a social platform matches a user 1 to be recommended and a user 2 to be recommended in a user database through the second attention list, the attention list of the user 1 to be recommended includes the user a, the attention list of the user 2 to be recommended includes the user B and the user D, and then the user list to be recommended includes the user 1 and the user 2; and acquiring an intersection list of the attention list of the user 1 to be recommended and the second attention list of the target user, wherein the intersection list comprises a user A, the intersection list of the attention list of the user 2 to be recommended and the second attention list of the target user, and the intersection list comprises a user B and a user D.
S1032, calculating the interaction weight of the user to be recommended and each user in the intersection list within a preset time length;
for example, as shown in fig. 5, the interaction weight between the user to be recommended and each user in the intersection list in the preset time period is calculated, that is, the interaction weight between the user 1 to be recommended and the user a, and the interaction weight between the user 2 to be recommended and the user B and the user D, respectively, in the preset time period are calculated.
As shown in fig. 6, a schematic flowchart of calculating an interaction weight provided in the embodiment of the present application includes the specific steps of:
s10321, configuring attenuation weights for the initial interaction weights within a preset time length based on a preset time granularity to obtain an interaction attenuation function;
the preset duration may be set based on a recommendation period, for example, if the social platform recommends a social user for the target user every other week, the preset duration may be one week, the recommendation weight of at least one to-be-recommended user in each week is calculated, a recommended user of the at least one to-be-recommended user is obtained based on the recommendation weight and a preset rule, and the recommended user is recommended to the target user.
Configuring attenuation weights for initial interaction weights within a preset duration based on a preset time granularity, wherein,
N(t)＝N0e-at；
n (t) is an interactive attenuation function in t unit times after being divided based on preset time granularity in preset time duration, N0Is the initial interaction weight, and a is the decay weight.
For example, if the time granularity is days and the predetermined duration is one week, then N (6) is the interaction decay function for the sixth day.
S10322, acquiring interaction data of the user to be recommended and each user in the intersection list;
the interaction data comprises an interaction type, an interaction frequency and an interaction time limit, for example, the interaction type comprises a message left by a user to be recommended to a user in an intersection list, the message left by the user to be recommended to the user in the intersection list is mutually complied with the message left by the user in the intersection list, and the like, the interaction frequency is the frequency of sending interaction between the user to be recommended and the user in the intersection list in unit time after the preset time length is divided based on time granularity, and the interaction time limit is the time from the beginning to the end of one interaction.
And S10323, acquiring interaction weight based on the interaction attenuation function and the interaction data.
For example, the time granularity is day, and the preset time duration is one week; on the first day, the server obtains an initial interaction weight 30 based on interaction data of a user to be recommended on the first day and the user in the intersection list, and obtains an interaction weight of 30 on the first day based on an interaction attenuation function; on the next day, the server obtains initial interaction weight 25 based on the interaction data of the user to be recommended on the next day and the user in the intersection list, and obtains the interaction weight of 18 on the next day based on an interaction attenuation function; on the third day, the server obtains an initial interaction weight 32 based on interaction data of a user to be recommended on the third day and a user in the intersection list, obtains an interaction weight 19 based on an interaction decay function on the third day, and so on, within a preset time length of one week, the interaction weights of the user to be recommended and the user in the intersection list are respectively 30, 18, 19, 15, 14, 17 and 25, and then the interaction weight of the user to be recommended and the user in the intersection list is finally 138.
In summary, based on the steps S10321, S10322, and S10323, the interaction weight between the user to be recommended and each user in the intersection list can be obtained. The beneficial effects brought by the technical scheme provided by some embodiments of the application at least comprise: the initial interaction weight is obtained based on the interaction mode diversity included in the interaction data, different intimacy relationships between users displayed by different interaction modes on the social platform are effectively utilized, and the accuracy of recommending the social users to the target user is improved; and the attenuation weight is configured based on time, so that the calculation of the interaction weight and even the recommendation weight is more reasonable and reliable.
It is to be understood that the present application is not limited to the method for obtaining the interaction weight.
And S1033, accumulating the interaction weights to obtain the recommendation weight of the user to be recommended.
For example, as shown in fig. 5, if the interaction weight of the user 1 to be recommended and the user a in the intersection list is 138, the recommendation weight of the user 1 to be recommended is 138; the interaction weight between the user 2 to be recommended and the user B in the intersection list is 50, the interaction weight between the user D and the user 2 to be recommended is 120, and the recommendation weight of the user 2 to be recommended is 170.
In summary, the recommendation weight of the user to be recommended is calculated based on steps S1031, S1032, and S1033.
S104, acquiring a recommended user from at least one user to be recommended based on the recommendation weight and a preset rule, and recommending the recommended user to a target user.
The preset rule can be that according to the numerical value of the recommendation weight, if the numerical value is larger, the recommendation priority of the user to be recommended is higher, and the recommendation user of the user to be recommended is determined based on the recommendation denomination of the social platform. For example, if the recommendation weight of the user 1 to be recommended is 138, the recommendation weight of the user 2 to be recommended is 170, and the recommendation name of the social platform is 1, recommending the user 2 to be recommended as the recommending user to the target user.

In another embodiment, the method for determining the liveness of the target user may be to calculate a ratio of the number of interest of the target user to the number of interest of the target user, where the number of interest of the target user generally reflects the participation of the target user in the social platform, and the number of interest of the target user generally reflects the authority degree and the favorite degree of the target user, when the number of interest/number of interest is greater than 1, the target user is preliminarily determined to be an active user, and when the number of interest/number of interest is less than 1, the target user is preliminarily determined to be a hotspot character, and it is necessary to further determine whether the target user is an active user. The above further judgment may adopt the judgment method in the first embodiment.
S702, under the condition that the activity of the target user is smaller than the activity threshold value, determining that the target user is an inactive user.

The implicit concern list is a user set which aims at the social platform and is concerned by similar users in an indirect concern mode. When the similar users mention that the frequency of a certain user-indicated pronoun in the published text exceeds an indirect attention threshold, but the similar users do not establish a unidirectional link or a bidirectional link with the user-indicated pronoun, the attention mode is defined as indirect attention.

The hotspot users are users with the number of interactions exceeding an interaction threshold and/or the number of concerned users exceeding a concerned degree threshold in the social platform. The detailed content of step 708 refers to step S101 shown in fig. 1, and is not described herein again.
And S709, acquiring a list of users to be recommended from a user database of the social platform based on the second concern list.

S7102, acquiring the interaction type of each user to be recommended and each user in the intersection list, and acquiring the interaction type weight V (i, j) corresponding to the interaction type.
V (i, j) is an integer with a value of 1 to 5, and a larger value of V (i, j) indicates that the social affinity between the target user and each user in the intersection list is higher, for example, the weight corresponding to the interaction type that the target user and the user in the intersection list comment each other is 5, and the weight corresponding to the interaction type that the target user approves the user in the intersection list is 5.
S7103, acquiring the kth interaction weight W of each user in the intersection list and the user to be recommended within a preset time length based on the interaction aging factor TF (t) and the interaction type weight V (i, j)k(i,j,t) Wherein:

And S711, acquiring a recommended user from at least one user to be recommended based on the recommendation weight and a preset rule, and recommending the recommended user to the target user.
The preset rule can be that according to the numerical value of the recommendation weight, if the numerical value is larger, the recommendation priority of the user to be recommended is higher, and the recommendation user of the user to be recommended is determined based on the recommendation denomination of the social platform. For example, if the recommendation weight of the user 1 to be recommended is 138, the recommendation weight of the user 2 to be recommended is 170, and the recommendation name of the social platform is 1, recommending the user 2 to be recommended as the recommending user to the target user.
