- Each record stored in the posting database 205 may contain various information other than the above.
- information representing the content of each post that is, text representing the content of the post, as well as images, videos, sounds, etc.
- interactions of users who do not belong to the target group are not used for calculation of influence. may not be included in the posted data. In this case, these information may not be collected or calculated.
- FIG. 4 is a flowchart showing an example of influence calculation processing according to the present embodiment.
- the influence calculation device 10 is provided with a certain topic and information indicating a target user (for example, a user ID of the target user, etc.).
- Information indicating these topics and target users may be given from the input device 101 of the influence calculation device 10, or the keyboard, mouse, etc. of a terminal connected to the influence calculation device 10 via a communication network. may be given from Also, two or more pieces of information indicating target users may be given, and two or more topics may be given.
- the group extraction unit 201 extracts a group of users who are interested in the topic as a target group (step S101).
- the group extraction unit 201 collects user IDs or user names from SNS services (more precisely, servers that provide SNS services), and then selects characters or character strings related to the topic as user IDs.
- SNS services more precisely, servers that provide SNS services
- a group of users included in the user name may be extracted as the target group.
- the target group is a group of users whose user IDs or user names include characters or character strings representing the game name or character name. should be extracted as
- the above extraction method is only an example, and the target population may be extracted by various methods other than this.
- the user ID or user name of each user is expressed as a word vector, and a set of users having user IDs or user names whose distance from the word vector representing characters or character strings related to the topic is equal to or less than a predetermined threshold You may extract as a target group.
- a set of users who have posted such posts a predetermined number of times or more may be extracted as the target group.
- a hash tag is a tag or label that a user can add to a post, and is generally represented by adding a hash symbol before a keyword.
- a target group is extracted as a range for evaluating the influence of target users.
- the conventional method of calculating the influence of users on SNS does not consider such a target group, it is difficult to accurately evaluate the influence of a group of users who are interested in a certain topic. can't.
- the group extraction unit 201 determines whether or not the target user is included in the target group extracted in step S101 (step S102).
- the influence calculation device 10 ends the influence calculation process. In this case, since the target user is not included in the target group, the target user does not have influence over each user included in the target group. At this time, the display control unit 204 displays information indicating that the target user does not have influence in the target group on the display device 102 of the influence calculation device 10 or on the display of the terminal connected via the communication network. may be displayed.
- the post collection unit 202 collects or calculates various information related to the target user's post from the SNS service, and collects or calculates this information.
- the post data created from is stored in the post database 205 (step S103). That is, the post collection unit 202 collects “post ID”, “post date and time”, “number of impressions within the group”, “number of follower interactions within the group”, and “number of follower interactions outside the group” for each post of the target user. , “Number of non-follower interactions within the group”, “Number of non-follower and non-group interactions", “Number of mutual follow interactions in the target group”, etc.
- the data is stored in post database 205 .
- each piece of information can be collected directly from the SNS service, the information can be used to create the post data, but if certain information cannot be collected directly, the information is calculated from other information. After that, post data is created using the calculated information. For example, while it is not possible to directly collect "follower and in-group interactions" and "follower and out-of-group interactions", if the number of follower interactions and the target user's follower user ID can be collected, the number of follower interactions and Using the user ID of the follower of the target user and the target group, the "follower and the number of interactions within the group" and the "follower and the number of interactions outside the group” may be calculated. This can be calculated by simple addition and subtraction. Similarly, with respect to other information, if the above information cannot be directly collected from the SNS service, the above information can be calculated by addition or subtraction from collectable information.
- step S103 information for a past period before the present is collected or calculated, but this period needs to be set appropriately. This is because collecting or calculating information for too long a period of time increases the processing load, and it is thought that the number of impressions and interactions of posts in the past has little relationship with the current actual influence of the target user. It's for. Therefore, in step S103, it is preferable to collect or calculate information for a period of one month to several months from the present. In the following, it is assumed that in step S103 above, the information for the period from the present to the past one month has been collected or calculated (thus, the post database 205 stores the information for the past one month from the present (that is, the latest This means that the post data related to the post is stored.).
- the post collection unit 202 also collects the number of followers of each user included in the target group from the SNS service.
- various types of information for calculating the influence of the target user on the target group are collected from the SNS service (or calculated from the information collected from the SNS service).
- the conventional method of calculating the influence of users on SNS does not consider the target group, and thus the above various information is not collected or calculated.
- the influence calculation unit 203 uses the post data stored in the post database 205 to calculate the influence of the target user within the target group (step S104).
- the post database 205 stores post data on n posts by the target user in the past month (last one month) (that is, post data) is stored.
- the influence calculation unit 203 calculates the influence of the target user in the target group by the following formula (1).
- n is the number of posts in the past month (most recent month)
- xi is the number of interactions with posts i from users included in the target group
- yi is included in the target group and mutual follow The number of interactions for post i from users who have Note that x i is the sum of the “follower and in-group interactions” and the “non-follower and in-group interactions” regarding post i.
- the above formula (1) calculates influence after excluding interactions from users who follow each other.
- customary or ritualistic interactions for example, because they are friends or because they follow each other.
- x i is the number of interactions with respect to post i from users included in the target group, but is not limited to this. Let x i be the number of interactions for post i from .
- c is the number of times the user has interacted with the number of posts n.
- the influence of the target user within the target group is calculated using the above equation (2), taking into account the value of each user j's interaction. This is calculated by replacing x i ⁇ y i in the above equation (1) with b in the above equation (2). Specifically, it is calculated by the following formula (3).
- b ji is user j's interaction value for post i.
- b ji b j for each i ⁇ [1, n] from the definition of the above equation (2), but may be different for each post i. For example, the newer the posted date and time, the larger the bji , and the older the posted date and time, the smaller the bji .
- the influence of the target user in the target group is calculated in consideration of the number of followers of users other than the target user. Specifically, the influence of the target user within the target group is calculated by the following formula (4).
- f ji is the number of followers of user j.
- f ji f j for each i ⁇ [1, n], but for example, f ji , the number of followers of user j at the time of post i, and f ji' may be different, so f ji is used.
- the influence is calculated by multiplying the reference value by the number of followers. ) is not used as a basis for calculating influence by multiplying it by the number of followers.
- any of the above influence calculation examples 1 to 3 it is possible to eliminate or mitigate the influence of blind interaction based on mutual follow-up, so the influence of the target user within the target group can be accurately calculated. Or it becomes possible to evaluate with high accuracy.
- conventional methods for calculating the influence of a user in SNS there are those that adjust the influence (that is, reduce the influence) due to the purchase of the number of followers, the purchase of interactions, etc.
- the present embodiment As explained, it is believed that there is no method for eliminating or mitigating the effects of blind interaction based on mutual follow-up.
- step S104 the display control unit 204 displays the influence calculated in step S104 (that is, the influence of the target user in the target group) on the display device 102 of the influence calculation device 10. Alternatively, it is displayed on the display of the terminal connected via the communication network (step S105).
- various display contents by the display control unit 204 are conceivable. user ID and user name.
- those who conduct influencer marketing or the target users themselves) can evaluate how much influence the target users have within a group of users. Become.
- the display control unit 204 also displays the formula used to calculate the influence (formula (1), (3) or (4 )) may be displayed, or together with (or in place of) the expression, the content of the expression may be displayed in sentences, diagrams, or the like.
- the display control unit 204 may display the influence of each target user as well as their ranking.
- the ranking of the influence of each target user may be based on the magnitude of the numerical value representing influence, or may be the ranking of influence of each target user.
- the rank indicates to which numerical value range the numerical value representing influence belongs to among a plurality of predetermined numerical value ranges. attached.
- the conventional method also ranks the influence and displays it on a display, etc., it is believed that the influence of the target user within the target group is not ranked.
- the influence calculation device 10 can calculate the influence of a certain user in a group of users who are interested in a certain topic, targeting users on the SNS. can.
- the influence calculation device 10 according to the present embodiment eliminates or mitigates the influence of the target user and the user who follows each other, for example, so that the influence of habitually or ritually interaction on the influence is reduced. can be eliminated or mitigated. For this reason, for example, when a person who conducts influencer marketing or the target user himself/herself evaluates influence, more accurate evaluation becomes possible.
