Embodiment for Carrying Out the Invention

[0010] FIG. 1 is a block diagram showing the overall hardware configuration of a system for calculating the characteristics between individual companies and between an individual company and the whole while ensuring confidentiality according to an embodiment of the present invention. As will be described later, with the system shown in FIG. 1, a plurality of users belonging to an enterprise or organization such as a company can exchange praise cards with each other to praise each other.

[0011] Here, the praise card is an example of what is called a "token". Generally, a token refers to something that can be transferred between users with specific information or value attached. In this embodiment, in order to enable users to use tokens for exchange as if they were actually exchanging cards with some meaning, the tokens for exchange are called praise "cards". However, the term "card" is just an example, and it can be called a coin, money, point, or anything else according to the embodiment. Also, the meta - card described later can be generally called a meta - token.

[0012] As shown in FIG. 1, the hardware configuration of this embodiment has a two - layer structure, which includes the part of the blockchain network 10 in the lower layer (the first layer) and the part other than the blockchain network 10 shown in the upper layer (the second layer) thereof. In the blockchain network 10 of the first layer, there are included a number of blockchain (BC) servers 11 (111, 112, 113, ···) and BC state databases (BC state DB) 12 (121, 122, 123, 124, ···) connected to each BC server 11. In the second layer, an application programming interface (API) server 13 (an example of a "server device") and a database 14 connected thereto are provided, and the software necessary for this system is installed therein and the necessary data is stored. Further, a plurality of users of this system belonging to a company or organization that has introduced this system access this system through a PC or a smartphone 16 (an example of a "transmission / reception device").

[0013] Also, an administrator 17 belonging to a company or organization can access the API server 13 through a management web screen 19 using a PC browser and perform necessary management operations. The management operations include editing / registering praise cards, user registration, displaying the transmission / reception history of praise cards, and the like.

[0014] Assuming that Company X is the entity providing this system, Company X constructs an environment using, for example, a specific cloud computing service of Microsoft as the second layer and manages data there. In Figure 1, the API server 13 and the management web screen 19 are servers managed by Company X. Some areas within the API server 13 are prepared for Company A, Company B, Company C, etc., which actually receive system provision from Company X and use this system with their own employees as users. That is, the servers of Company X manage the systems provided to each of Company A, Company B, Company C, etc. on the cloud. The administrator 17 at the upper left in Figure 1 is an administrator of either Company A, Company B, Company C, etc., and the two users 15 shown below are also users of the same organization. Figure 1 shows that the user 15 is using a smartphone 16, but the user 15 can also use a PC.

[0015] Through the application of the API server 13, the database 14 manages the content of the praise cards and the information of the users. When the user 15 conducts praise card exchanges using a PC, it is through a browser. When the user 15 conducts praise card exchanges using a smartphone, a dedicated praise card app is installed and used. There are multiple types of apps for users to conduct praise card exchanges, which can be downloaded and installed by accessing the download site in advance according to the platform the user usually uses.

[0016] Both the interface of the PC browser and the praise card app of the smartphone 16 directly access the API server 13 and communicate via the network. The management web server creates HTML data based on the data recorded in the API server and sends it to each user's smartphone 16 to display a screen based on that HTML data on the smartphone.

[0017] When an actual user sends a compliment card to another user, data on who sent what kind of compliment card to whom is sent to the API server 13. Then, the API server 13 records in the database 14 the specific names of the person who actually sent the compliment card and the person who received the compliment card, the sent compliment card, and the accompanying message. Furthermore, the user IDs of the sender and the recipient with the organization names to which these people belong removed, the information on who sent to whom, and the ID of the meta card corresponding to the sent compliment card are sent to the BC server 11 via the blockchain API. And the BC server 11 on the blockchain records the received information.

[0018] The BC state DB 12 is a database managed by the BC server, where the BC server writes to the BC state DB using functions such as "token issuance" and "token transfer". As a result, this information is registered on the blockchain (BC). There are multiple "token information" databases hanging on each BC server on the blockchain server network, and the contents of all these databases are exactly the same. So once the BC server writes to the BC state DB using functions such as "token issuance" and "token transfer", it is transferred to the databases of all BC servers connected in the network, and the same data is held.

[0019] Figure 2 shows an overview of the data stored in the databases exchanged between each of the hardware shown in Figure 1. In Figure 2, the lower row shows the data stored in the blockchain (BC) state database (BC state DB) 12, and the upper row shows the data stored in the API server 13.

[0020] Next, an explanation will be given of the theoretical background that makes it possible to enhance the engagement of users with the company or organization to which they belong by sending praise cards to each other. The system of this embodiment is based on the Success Loop Model of Daniel Kim of the Massachusetts Institute of Technology as this theoretical background. FIG. 3 schematically shows this Success Loop Model.

[0021] In FIG. 3, the starting point is the phase of "quality of relationship". This is a phase in which the density of communication is increased through conversations and exchanges, and feelings such as a sense of camaraderie, unity, assistance, and cooperation are fostered. It can also be said to be the groundwork (warming up the place) for running the Success Loop Model. If this phase is neglected, it becomes difficult to create the subsequent success loop of "quality of thinking" → "quality of action". Also, if starting from "quality of result" instead of "quality of relationship", there is a risk of falling into a cycle of failure where there is excessive focus on numerical goals (quality of result), leading to confrontation and friction within the organization and rampant blame-shifting.

[0022] When dialogue and cooperation increase due to an improvement in the "quality of relationship", the communication density within the organization increases, and at the same time, conversations with people and organizations that had few contacts before also increase. This increases the opportunity to come into contact with "distant knowledge" such as different perspectives, values, and ways of thinking, and deep thinking (introspection) such as why there is a gap with one's own way of thinking and whether one has only been able to see things in a short-sighted manner begins to emerge. This also aligns with the concept of "The Strength of Weak Ties" proposed by sociologist Mark Granovetter in 1973. "The Strength of Weak Ties" means that information from strong connections (for example, the usual organization) is mostly predictable, but information from weak connections (for example, an organization that had few contacts before) can give new discoveries that one has not noticed. Since the "quality of thinking" is improved by firmly accepting "distant knowledge", an attitude of listening to the other person's story is important, and a positive cycle such as problem discovery / problem solving and proposal of new ideas is generated starting from listening.

[0023] When the "quality of thinking" improves, specific actions begin as one tries to put into practice new ideas discovered by being liberated from homogenized thinking. This is the "quality of action". And to further improve this "quality of action", two points are important: (1) having ownership and (2) providing opportunities and a place to act. "Having ownership" means that in the process of improving the quality of thinking, one comes into contact with "distant knowledge" such as different perspectives, values, and ways of thinking from one's own, and by reflecting on one's own values (introspecting), one clarifies what one should do (what one wants to do), which is synonymous with progressing towards making things one's own. It is not the feeling of being forced, but rather how much one has made things one's own that has a great impact on the quality of action. Next, "providing opportunities and a place to act" means that even if one has ownership through introspection, without a place to practice, the enthusiasm will gradually fade. Therefore, providing a place at the right time, combined with "having ownership", can be said to be the two wheels for improving the quality of action.

[0024] The improvement of the "quality of results" is achieved by improving the "quality of relationships → thinking → action", so we do not adopt the idea of only improving the quality of results. By increasing the density of communication (quality of relationships) through conversations and exchanges, introspection progresses by coming into contact with different values and ways of thinking from one's own, one can make things one's own (quality of thinking), and by having ownership and continuing to challenge (quality of action), one can approach the results set as the desired image. Through this successful experience, one can have confidence that one's efforts were not in vain, and furthermore, the cycle of success of increasing communication, having conversations, and having ownership and challenging continues. The above are the characteristics of the success cycle model.

[0025] Next, referring to FIG. 4, the praise cards actually exchanged between users belonging to each organization and the meta-cards prepared in advance separately will be described. In the middle of FIG. 4, in the column of the meta-card 100 written with "Classification by Social Psychological Research" below, 15 types of meta-cards from "Problem Discovery and Solution Awareness" to "Overall Perspective" are shown. In the column of the praise card 101 of the company / organization written with "Design for Each Company / Organization" below on the left side thereof, 12 types of praise cards from "Break through" to "Nice Support" are shown. On the right side, in the individual characteristics 102 written with "Characteristic Analysis by Statistical Survey" below, 7 characteristics such as "Creativity" are listed.

[0026] FIG. 5(a) shows a table explaining what each meta-card shown in FIG. 4 is like. As described above, these 15 types of meta-cards are derived from social psychological research, and even if the companies or organizations (Company A, Company B, Company C,...) introducing the system of this embodiment are different, these 15 types of meta-cards are commonly used. FIG. 5(b) shows an example of which phase of the aforementioned success cycle model these 15 types of meta-cards correspond to. The significance of associating each of these meta-cards with the phases of the success cycle model will be described later. On the other hand, the system of the praise cards 101 of each company / organization shown in FIG. 4 can be designed independently by each company or organization according to the characteristics of the company or organization when introducing the system of this embodiment. Therefore, if the companies or organizations introducing the system of this embodiment are different, the system of praise cards prepared will naturally be different. Note that the association between each meta-card shown in FIG. 5(b) and the phases of the success cycle model is merely an example and can vary according to the design of the system.

[0027] And each company / organization, when designing the system of praise cards, associates each of the praise cards with any one of the 15 types of meta-cards. In FIG. 4, a plurality of arrows connecting each of the praise cards 101 with any one of the 15 types of meta-cards 100 indicate which praise card is associated with which meta-card.

[0028] Users belonging to a company or organization that has introduced the system of this embodiment send each other any of the praise cards 101 independently designed by their own company. In practice, each user exchanges through an app or software on a device such as their own smartphone or PC.

[0029] Figure 6 imaginatively shows a situation where praise cards are actually exchanged in a certain company or organization. In the example of Figure 6, as praise cards, "Gold Card" (the highest level of praise) 1031, "Great Direction" (which pointed the way in a stuck meeting or thought process) 1032, "Good Connection" (connected me with someone who contributed to idea creation) 1033, "Nice Idea" (came up with an idea I couldn't think of) 1034, and "Good Job" (praising someone who worked hard) 1035 are prepared. Users 1041, 1042, 1043, and 1044 belonging to this company or organization are sending and receiving these prepared praise cards to and from each other. And when sending, as described above, messages as shown in speech bubbles 1051, 1052, 1053, and 1054 can be attached to the praise card and sent.

[0030] The actual way to send a compliment card is as follows: In the app or software, first select the person to whom you want to send the compliment card from, for example, the list in the app, then select the type of compliment card you want to send from the list of types, write a text message if necessary, and then send it. The action of the person for which the compliment card is being sent is not particularly displayed, but if the sender describes what they are complimenting about in the message, for example, while considering what actions of the recipient they are complimenting, the person who receives the compliment card can understand what they are being complimented on by looking at the attached message. The compliment cards sent by the user are listed on the user's smartphone, and the compliment cards received by the user are listed on the user's smartphone. The user who receives the compliment card will have received it by opening the received compliment card.

[0031] By users sending compliment cards to each other in this way, for example, receiving a compliment card from another user can give them confidence in their actions, give them a boost for their next actions, or help them understand their own characteristics that they were not aware of. Also, when users belonging to companies or organizations send compliment cards to each other, the cycle of the success cycle model circulates, increasing the possibility of leading to the success of the company or organization, and further contributing to enhancing the engagement with the company or organization.

[0032] When a user sends a compliment card to another user, it can be considered that a single vector is created. Therefore, when a large number of users belonging to a certain company or organization send compliment cards to each other, a large number of vectors are created, and they can be displayed as a network diagram connecting the vectors with arrows. And based on this network diagram, various analyses such as the density of the arrows and the number of cards can be performed. The compliment card is positioned as a tool for enhancing the "quality of relationships", "quality of thinking", "quality of actions", and "quality of results" in the aforementioned success cycle model. A company or organization that introduces the system of this embodiment can obtain information about which of the four phases of "quality of relationships", "quality of thinking", "quality of actions", and "quality of results" the company itself is in by analyzing the data of the compliment cards sent among the users belonging to the company or organization as described below.

[0033] Figure 7 shows a block diagram showing the overall hardware configuration of the system shown in Figure 1 from the perspective of a user who uses this system. As described above, the hardware configuration has a two-layer structure, which is the part of the lower (first layer) blockchain network 10 and the part other than the blockchain network 10 shown in the upper (second layer) thereof. However, even when dividing the area with a focus on the user, it has a two-layer structure as shown in Figure 7. The first layer of Figure 7 is an area for managing personal relationships and common social values regardless of the company or organization to which the user belongs, while the second layer is an area for actually exchanging compliment cards within a closed relationship in units of each company or organization to which the user belongs.

[0034] Figure 8 shows the information area divided from the perspective of information to be publicly disclosed to society (information in the open area) and information that is shared within an enterprise or organization to which the user belongs but not publicly disclosed outside (information in the closed area). And the technology of blockchain is used for the management of information in this open area. In this way, the way of data management has a two-layer structure. At the second layer, the exchange of praise cards is managed in a closed area for each enterprise or organization. The first layer part uses the technology of blockchain to manage information across enterprises that use praise cards and discloses it to society.

[0035] As shown in Figure 8, for the first layer of the two layers, only the types of meta-cards sent from User A to User B are recorded in a form that removes personal information and company information. Here, Users A and B are represented only by internal user IDs. In this way, the "sender ID" and "recipient ID" are used to represent which user ID sent to which user ID, and which types of meta-cards were sent are recorded.

[0036] As mentioned above, the "praise card" is designed based on the values and corporate philosophy of each enterprise. On the other hand, the 15 types of "meta-cards" are more universal than the "praise cards" derived from social psychology research as mentioned above. When designing the praise cards for each enterprise, which of these meta-cards each enterprise's praise card corresponds to is associated. When actually creating praise cards for each company, the titles of the 15 types of meta-cards shown in Figure 5(a) and the description of what kind of praise each meta-card is for are prepared, so the company's praise cards can be associated with the meta-cards by referring to this.

[0037] In FIG. 8, when looking at the first - layer data, it is possible to see across companies which of the 15 types of meta - cards were sent, but it is not possible to know specifically which company's it is, who sent the card, or the specific person to whom it was sent. However, it is possible to compare which meta - cards were exchanged among Company A, Company B, and Company C, and by comparing, it is possible to analyze the characteristics of the relationships between employees of each company. In the second layer, the actual person and the actual organization to which the person belongs are identified, and it is possible to know within the closed environment of each company or organization what kind of praise cards and messages were sent.

[0038] Blockchain is a public thing that anyone can see, and the purpose of making it so is to ensure transparency. For example, if Company A using the system of this embodiment exchanges 100,000 praise cards in a year, each and every one of them is recorded on the blockchain. Since the content of the blockchain can be seen by a third party as described above, anyone can confirm that Company A actually exchanged 100,000 praise cards in a year. And, once data is recorded on the blockchain, it has the characteristic that the data cannot be modified or tampered with, so a company cannot modify the once - written data to its own advantage later.

[0039] Also, when Company A, Company B, Company C... send praise cards, information about the common meta - cards is recorded in the blockchain network. Therefore, by looking at the blockchain, it is possible to compare and analyze the necessary information about Company A, Company B, Company C.... This is also another purpose of utilizing the blockchain.

[0040] Regarding the blockchain, as shown in FIG. 1, each of the multiple blockchain (BC) servers 111, 112, 113, ··· is also referred to as a node, and they have the same structure where the information each node holds is exactly the same. The server managed by Company X that provides the system of this embodiment is also included in the blockchain network. However, when other servers are transferred to the public blockchain (data), multiple unspecified companies will manage the data of this blockchain. For this reason, it becomes an environment where it is unknown which company or who has the server that manages the blockchain hardware and how it is managed. Regarding the blockchain, Company X that provides the system constructs an environment using, for example, a specific cloud computing service of Microsoft as the second layer and manages data there. However, it is impossible to know what kind of cloud server other companies are using or whether they are using on-premises servers.

[0041] Regarding FIG. 8, further explanation is as follows. In the closed area, the card master information includes "Card ID", "Meta Card ID", "Community ID", "Card Name", "Card Description", and "Card Image". "Card ID" is the ID of each commendation card created for each company or organization. "Meta Card ID" is the ID indicating which one of the 15 types of meta cards associated with the commendation card. "Community ID" is the ID for each company or organization indicating which company or organization is using it. "Card Name" is the name of the card. "Card Image" is the image data depicted on the commendation card and can be changed for each company.

[0042] "Community Information" is the part that records information about companies and organizations, and includes "Community ID", "Community Name", and "Community Information". "Community ID" is the same as that in the master information, "Community Name" is the name of the company or organization using the praise card, and information about the company is recorded in "Community Information". "User Information" is the part that records information about each individual user, and "User ID", "User Name" (the person's own name), "Affiliated Community ID" is the ID of the company to which the "Community Information" belongs, and the email address is the email address of each user.

[0043] The information written in the above "Closed" area is not written to the blockchain network. The information written to the blockchain network is the information in the "Open" area. As described above, in the "Blockchain Transmission / Reception Record", "From ID", "To ID", "Meta Card ID", and "Card ID" are written. Also, in the "Meta Card Master Information", not only the "Meta Card ID" but also the "Meta Card Name" and "Meta Card Explanation" are managed.

[0044] Next, in the companies and organizations that use the system of this embodiment, the analysis of the actually exchanged praise cards will be described. As described above, the system of this embodiment is based on the success cycle model proposed by Mr. Daniel Kim. However, until now, it has not been possible to visualize in which phase of the model the company or organization is. In this embodiment, as shown in Fig. 5(b), each of the 15 types of meta cards is associated with one of the phases of "Quality of Relationship", "Quality of Thinking", and "Quality of Action" in the success cycle model. The description of what each meta card shown in Fig. 5(a) is like is made public on the blockchain, but the association between each meta card shown in Fig. 5(b) and each phase of the success cycle model is not managed on the blockchain and is held inside the analysis software and used for calculation.

[0045] Suppose hundreds of employees of a certain company exchange compliment cards with each other. By examining how many corresponding meta-cards are exchanged, various analyses can be conducted. For example, if 80% of the exchanged cards correspond to the meta-cards of "quality of thinking", or if it is found that more compliment cards corresponding to "quality of action" are being used, it can be understood, roughly speaking, at which phase of the success cycle model the communication is taking place within that company. That is, it becomes possible to visualize at which phase of the success cycle model that company or organization is in.

[0046] Figure 9 shows an example of the results of analyzing the characteristics of three companies or organizations, Company A, Company B, and Company C, by aggregating the exchange of compliment cards. As shown in Figure 4, the compliment cards designed by each company are associated with 15 types of meta-cards, and each meta-card is associated with one of the phases of the success cycle model based on the table in Figure 5(b).

[0047] Therefore, by aggregating the compliment cards exchanged over a certain period, it is possible to aggregate for each of Company A, Company B, and Company C how many of the 15 types of meta-cards shown on the horizontal axis of Figure 9 were exchanged. Referring to Figure 9 obtained in this way, for example, it can be seen that Company A sends relatively many meta-cards such as "enthusiastic actions" and "cultivation of unity", but does not send any meta-cards of "desire to achieve goals" at all, and the characteristics of each company can be visually understood. Also, even if the compliment cards are created according to the specific circumstances of each company or organization, by associating them with more universal meta-cards for analysis and arranging Company A, Company B, and Company C as shown in Figure 9, the characteristics of multiple companies or organizations can be compared with each other.

[0048] As described above, by users belonging to a company or organization sending praise cards to each other, the chain of the success cycle model circulates, leading to the success of the company or organization, further strengthening organizational engagement, and for users belonging to the company or organization using the system of this embodiment, it is possible to derive the characteristics of each individual user, and to find users who are characteristically similar and users who are characteristically complementary to each user. This will be described below.

[0049] As a preparatory step for this, for a sufficient number of employees belonging to a certain company to derive socially general characteristics, among the 15 types of meta-cards shown in Fig. 5(a), an example is to conduct a questionnaire asking them to select 5 meta-cards that they think are important in doing their jobs. Then, based on the results, using a well-known method called cluster analysis, a table is created for calculating the points given to the sender or receiver each time a meta-card is sent or received.

[0050] An example of creating this table is as follows. First, each person who participated in the questionnaire is classified into 7 factors (corresponding to the numbers on the horizontal axis) shown in Fig. 10. However, this is just an example, and the number of factors can be changed according to the implementation mode. Also, the numerical values in the table of Fig. 10 have been deleted except for some. And if, for example, there are 49 people belonging to the first factor, and among them 71% selected "3 Future orientation and visioning ability", 63% selected "14 Idea sending and proposal ability", and 55% selected "6 Enthusiastic action". Although not shown in the table of Fig. 10, similar numbers are required for other parts of the table. For the 7 classified factors, as an example, labels such as "Creativity", "Honesty", "Dialogue ability", "Execution ability", "Overview ability", "Transformation ability", and "Leadership ability" are assigned to each from 1 to 7.

[0051] Adding the numbers on the vertical axis of the first factor, since one person has selected 5 meta-cards, the total is 500%. The same applies to other factors. In the table of Fig. 10, each number included in the gray column from the upper left to the lower right is the largest percentage value in each row. Also, Fig. 11 is the result of recalculating the ratios of the 7 numbers in the same row of Fig. 10 so that the sum of the 7 numbers is 100 without changing the ratios. Regarding Fig. 11, although only some numbers are shown, when the numbers in the same row for each meta-card are summed, the result is 100. This table of Fig. 11 becomes the table for calculating the points given to the sender or receiver in relation to the corresponding meta-card when a praise card is sent and received. Note that the basic table of Fig. 11 is obtained from the table of Fig. 10 for the convenience of calculation, but the point calculation may also be performed using the table of Fig. 10.

[0052] Fig. 11 is a table showing the correlation between each meta-card and each factor in %. For example, if user A sends a praise card corresponding to the first meta-card of "awareness of problem discovery and solution" to user B, the system of this embodiment internally adds 0.14 points to "creativity", 0.19 points to "honesty", 0.02 points to "communication ability", 0.20 points to "execution ability", 0.12 points to "overview ability", 0.13 points to "transformation ability", and 0.20 points to "leadership ability" as B's share. When such calculations are performed every time a praise card is sent over a certain period, the points for each of these 7 factors for user B are accumulated. As a result, to some extent, the personal characteristics of user B can be known depending on how many points are obtained for each factor.

[0053] Fig. 12 shows an example of an image of a smartphone that displays an evaluation of one's own characteristics obtained by performing the above-described point calculation over a certain period. In the upper right side slightly above the center of the screen, "1 Interaction ability 28%", "2 Overlooking ability 23%", "3 Creativity 17%", "4 Honesty ability", "5 Execution ability 9%", and "6 Others 11%" are displayed from top to bottom. This represents the person's characteristics in percentages, and in the pie chart on the left side, the arc lengths corresponding to the ratios of the respective characteristics are color-coded and displayed. In this person's case, it can be seen that the interaction ability shows the highest ratio. By looking at this, based on the praise cards sent by others, it is possible to visualize what one is being recognized for by others. Similarly, the praise cards sent by oneself to others can be displayed in the same way, and thereby it is possible to visualize what characteristics one values more in others.

[0054] As described above, based on the praise cards received from other users belonging to the same company or organization, it becomes possible to visualize what one is being recognized for by others or what values one cherishes. This visualized information also serves as a trigger to notice the "uniqueness" that is being recognized by others, and it also becomes the driving force to demonstrate that uniqueness in the workplace or the like as a value.

[0055] Subsequently, an explanation will be given regarding finding users who are similar in characteristics and users who are complementary in characteristics to each user. For this, clustering analysis methods such as the K-means method and hierarchical clustering are used. Fig. 13 is a diagram for explaining this method. In Fig. 13, for example, the vertical axis is set as a meta-card such as "Awareness of problem discovery and solution", and the horizontal axis is set as a meta-card such as "Desire to achieve goals". Based on the table in Fig. 11, the number of these meta-cards sent is tabulated and plotted, and a graph as shown in Fig. 13, for example, is obtained. In Fig. 13, each point corresponds to one user who has sent or received a praise card.

[0056] Note that although FIG. 13 shows only two axes, the vertical axis and the horizontal axis, for simplicity, there are actually 15 types of meta-cards, and since each has transmission and reception, a virtual space of a total of 30 axes (30 dimensions) can be assumed. That is, plots as shown in FIG. 13 are made in a 30-dimensional space. And, for example, when using the K-means method, by designating, for example, "7" as the number of clusters, seven clusters are formed in this 30-dimensional space. Further, by performing distance calculation for each plot belonging to each cluster, the center (centroid) of that cluster is obtained.

[0057] As a result, all the plotted points, that is, all users, are classified into one of the seven clusters. One of "creativity", "honesty", "interactive ability", "executive ability", "overview ability", "transformative ability", "leadership ability" under the individual characteristics 102 shown on the right side of FIG. 4 is labeled for each of these seven clusters.

[0058] By doing so, it is possible to know which cluster each user belongs to. And when displaying a list of users belonging to the same cluster, for example, the list can be made in ascending order of the distance from the centroid. Users belonging to the same cluster can be considered to have similar characteristics. As a result, for example, when one has to leave work for some reason, the possibility of smoothly continuing the work increases by filling in users with similar characteristics to oneself.

[0059] On the one hand, it can be considered that users belonging to different clusters have different characteristics. In particular, users belonging to clusters with the longest distance between centroids can be considered to have complementary characteristics, so they can be called "complementary clusters". Therefore, for example, when starting a new project and wanting to gather diverse talents with different characteristics, it becomes possible to gather talents with a wide range of characteristics by gathering talents belonging to different clusters with a large distance between their centers.

[0060] As shown in FIG. 12, it is possible to display users with characteristics similar to oneself and users in a complementary relationship with oneself. That is, at the lower part of the smartphone screen, other users are shown in two levels. The upper ones are users with characteristics similar to oneself, and the lower ones are users in a complementary relationship with oneself. In this way, it is possible to visualize users with characteristics similar to oneself and users in a complementary relationship with oneself.
