JP, 2005-166931, A JP, 2013-242657, A

Here, in a management system that integrates and manages information owned by a plurality of businesses, a mode in which an information analysis service is provided in order to promote the use of information can be considered. For example, when the management system receives a purpose of use of information from the user, the management system notifies the analyst who analyzes the information according to the purpose of use of the purpose of use. Then, when the management system accepts the analysis result by the analyst, the management system provides the accepted analysis result to the user.

However, in such a management system, it may be difficult to appropriately set the reward for the analyst. For example, a mode is conceivable in which a plurality of analysts are notified of the purpose of use and the analysis is individually performed to motivate the improvement of analysis accuracy. However, when the reward is set according to the analysis accuracy, many rewards are set for the analyst who has the highest analysis accuracy but takes the longest time to provide the analysis result.

The present application has been made in view of the above, and appropriately sets a reward for an analyst.

The calculation device according to the present application, a presentation unit that presents a purpose of using the information to a plurality of analysts who analyze information registered by a plurality of businesses, and an order in which each analyst provides an analysis result, or It has a calculating part which calculates the reward for each analyst according to at least one of the precision of each analysis result.

According to the aspect of the embodiment, the reward for the analyst can be appropriately set.

FIG. 3 is a diagram illustrating an example of an estimation process executed by the information management device according to the embodiment. FIG. 4 is a diagram illustrating an example of a providing process executed by the information management device according to the embodiment. FIG. 5 is a diagram illustrating an example of a calculation process executed by the information management device according to the embodiment.

The information management device 10 is an information processing device that executes a presentation process, a selection process, an estimation process, a provision process, and a calculation process (hereinafter, may be collectively referred to as “each process”). It is realized by a cloud system or the like. For example, the information management apparatus 10 may be collectively referred to as web servers 110 to 130 (hereinafter, may be collectively referred to as “web server 100”) and business server 210 to 230 (hereinafter, may be collectively referred to as “business server 200”). , And a DS (Data Scientist) terminal 300 via a network N such as the Internet (see, for example, FIG. 6). The information management device 10 may be capable of communicating with any number of web servers 100, business entity servers 200, and DS terminals 300.

The web server 100 is an information processing device that realizes various web services provided by the business operator Z, and is realized by a server device, a cloud system, or the like. For example, the web server 110 provides various services related to web search. The web server 120 also provides services related to electronic commerce such as online shopping mall services and Internet auctions. The web server 130 also provides a distribution service for distributing various contents such as news, various advertisements, real estate advertisements, music, still images, moving images, movies, and the like.

In addition to the web services described above, the web server 100 may realize any web service. Here, the web server 100 holds logs for providing various web services. In such a log, for example, an identifier (for example, a user ID (Identifier)) for identifying a user who has been provided with a service, an attribute of the user (for example, a demographic attribute or a psychographic attribute, etc.), The contents of the provided service (for example, contents of distributed information and purchase history) are included. The format and content of the information stored as a log may be different for each service or may be prepared.

The company server 200 is an information processing device used by each company, and is realized by, for example, a server device or a cloud system. For example, the business server 210 is an information processing device used by a business A that sells cosmetics. Further, the business entity server 220 is an information processing apparatus used by a business entity B that manufactures and sells food. The business server 230 is an information processing device used by a business C that sells various products.

Here, the business entity server 200 manages information regarding services provided by each business entity. Here, the information about the service by each business operator is, for example, information in which the user who has been provided with the service by each business operator is associated with the content of the service provided to the user, that is, each It is a log of services by the business operator. In addition to such information, the business server 200 can employ arbitrary information as long as it is information about services provided by each business.

[1-1. Regarding the presentation process provided by the information management device]
Hereinafter, various services executed by the information management device 10 will be described. First, an example of the presentation process executed by the information management device 10 will be described with reference to FIG.

[1-1-1. Outline of presentation processing provided by information management device]
Like the web server 100, the information management device 10 provides a service (hereinafter, may be referred to as “data management service”) managed and operated by the business operator Z. More specifically, the information management device 10 accepts registration of information held by a plurality of businesses, and uses various services based on the accepted information, that is, information of a plurality of businesses. Provided cloud service.

For example, the information management device 10 accepts registration of information regarding services by the business operators A to C from the business operators A to C. In such a case, the information management device 10 holds the registered information and, in response to the request, provides the held information only to the business operator as the registration source. For example, the information management device 10 discloses the information registered by the business operator A only to the business operator A, and conceals the information registered by the business operator A to the business operators B and C. That is, the information management device 10 provides a cloud service that manages and holds information.

Here, when the information acquired by a plurality of businesses is used in an integrated manner, it is considered that new value can be provided to each business. For example, when the information on various web services acquired by the business operator Z and the information on cosmetics sales acquired by the business operator A are multiplied, what kind of web search is performed by the user who frequently purchases cosmetics? It is thought that it is possible to realize statistical analysis of past information such as, and prediction of users who are likely to purchase cosmetics, which are new products. On the other hand, there may be a request that the information acquired by each business operator should not be disclosed to other business operators.

Therefore, the information management device 10 executes the following processing as part of the cloud service. First, the information management device 10 receives registration of the purpose of use of information. Here, the purpose of use is the purpose of use of the information registered by each business operator, and is information indicating the content of the problem to be solved, the content of prediction, the content of analysis, and the like. When accepting such registration of the purpose of use, the information management device 10 presents the purpose of use to the data scientist (hereinafter referred to as “DS”). For example, the information management device 10 presents the purpose of use to the DS1 belonging to the business operator Z, the event persons A to C who registered the information, and the DS2 different from the business operator Z who manages the information. To do.

In such a case, DS1 and DS2 (hereinafter sometimes simply referred to as DS) create an analysis result that achieves the purpose of use. For example, when the content of the purpose of use is related to the analysis of past information, the DS integrally uses information registered by a plurality of businesses to create an analysis result of the content according to the purpose of use. Further, for example, when the purpose of use is a solution to a problem or a prediction, the DS creates a model for solving or predicting such a problem as an analysis result. For example, the DS creates, as an analysis result, a model in which the characteristics of information registered by a plurality of businesses are collectively learned, that is, a model learned by using information registered by a plurality of businesses. Further, when the purpose of use is prediction of a predetermined event, the DS creates a model for predicting the predetermined event as an analysis result using information registered by a plurality of businesses.

Then, the information management device 10 provides the analysis result created by the DS to the business operator that is the registration source of the purpose of use. As a result, the information management device 10 realizes the provision of a service that uses information registered by a plurality of companies in an integrated manner while ensuring the confidentiality of information registered by another company to some extent. That is, the information management device 10 does not provide the information provided by each business operator to each business operator, but uses the information registered by each business operator according to the purpose of use registered by each business operator. And provide the analysis results produced by the DS.

Here, it is difficult to determine what kind of information and how to combine it to obtain an analysis result that satisfies the purpose of use. For this reason, it may be difficult to create an analysis result that satisfies the purpose of use of each company only with the DS1 of the company Z that manages information. Therefore, the information management device 10 presents the purpose of use to the DS2 different from the business operators A to C and Z. Then, the information management device 10 provides the analysis result created by the DS2 to the business operator. Therefore, the information management device 10 can promote the use of information registered by a plurality of businesses.

In addition, the information management device 10 sets a predetermined reward for the DS when the analysis result is provided by the DS. Further, when the analysis result is provided by the DS, the information management device 10 sets a predetermined reward for the business operator who has registered the information used by the DS.

For example, when the information management device 10 receives a purpose of use such as “prediction of users who purchase new products” from the business operator B, the information management apparatus 10 provides the purpose of use to the DS2, and each business operator A to C, Z Of the registered information, the information requested by DS2 is provided to DS2. Then, for example, the information management device 10 combines the log related to the web service provided by the business operator Z and the information about the cosmetics sales provided by the business operator A to perform “prediction of user who purchases new product”. When a model is created, the model is provided to the business operator B and a predetermined reward is received from the business operator B.

In such a case, the information management device 10 provides a predetermined reward to the DS2 for which the model is created, using the reward received from the business operator B as a resource. In addition, the information management device 10 provides a predetermined reward to the business operators A and Z who have registered the information used by the DS2, using the reward received from the business operator B as a source. The information management device 10 may provide a predetermined operating cost to the business operator Z who operates the above-described outsourcing service, using the reward received from the business operator B as a source of funds.

That is, the information management device 10 opens a series of flows, such as providing analysis results satisfying the purpose of use, to the external DS by using the information registered by each business operator, and the algorithm or model from the external DS. Accept registration of analysis results. Then, the information management device 10 provides the analysis result to each business operator. In other words, the information management device 10 provides an outsourcing service for analyzing information registered by a plurality of businesses. Therefore, the information management device 10 can promote the use of information registered by each business operator.

[1-1-2. Regarding an example of presentation processing]
Hereinafter, an example of the presentation process executed by the information management device 10 will be described with reference to FIG. First, the information management device 10 collects various logs from the web server 100 (step S1). Further, the information management device 10 accepts the registration of the information held by the business operator A from the business operator server 210 and the registration of the information held by the business operator B from the business operator server 220 (step S2). The information management apparatus 10 may accept registration of information held by the business C from the business server 230.

Further, the information management device 10 accepts registration of a task to be used, for example, from the business entity server 230 (step S3). The information management device 10 may accept registration of the purpose of use from the business operator A or the business operator B in addition to the business operator C. For example, in the example shown in FIG. 1, the information management device 10 accepts registration of the purpose of use “predictor of purchase of new cosmetics” and the reward “reward R1” from the business operator A, and the purpose of use “product” from the business operator B. The registration of the sales forecast of A" and the reward "reward R2" is accepted, and the registration of the purpose of use "prediction of users interested in the product B" and reward "reward R3" is accepted from the business operator C. In such a case, the information management apparatus 10 presents the purpose of use to the data scientist DS1 belonging to the business operator Z (step S4) and presents the purpose of use to the external data scientist DS2. Yes (step S5).

Here, although omitted in the example shown in FIG. 1, the information management apparatus 10 specifies the purpose of use for which each DS creates an analysis result from each DS that has disclosed the purpose of use, and the analysis result for each DS. Accept the specification of the type of information used when creating. In such a case, the information management device 10 identifies the specified type of information among the information registered by each business operator, and inquires of the business operator who registered the specified information whether or not it can be used. .. Then, when the use is permitted, the information management device 10 provides the DS with the specified type of information.

The information management device 10 may receive a proposal of a reward for creating the analysis result from each DS. In such a case, the information management device 10 inquires of the business operator that has registered the designated purpose of use whether or not the analysis result can be created by each DS, and if the permission is obtained, the permission is obtained. Information may be provided to each DS.

The information management device 10 also receives from DS1 the provision of a model according to the purpose of use designated by DS1 (step S6). The information management device 10 also receives from DS2 the provision of a model according to the purpose of use designated by DS2 (step S7). In such a case, the information management apparatus 10 provides the business with the model provided by each DS. For example, when the information management apparatus 10 receives from DS2 a model satisfying the purpose of use registered by the business C, the information management apparatus 10 provides the model to the business C (step S8).

In addition, when the information management apparatus 10 uses the information registered by the business operator A and the business operator B when the DS2 uses the information registered by the business operator C to create the model that satisfies the purpose of use, the business operator A and the business operator B are used. Is provided with a reward for using the information (steps S9 and S10). Further, the information management device 10 provides the DS2 with a reward for creating the model (step S11).

[1-1-3. Promotion of entry]
Here, it is considered that a large amount of data is required to predict the event registered as the purpose of use and to improve the accuracy of the model that solves the problem. For this reason, when the number of businesses that register data is small, or when only a part of the data held by each business is registered, it is not possible to appropriately create analysis results that satisfy the purpose of use. There is a fear.

For example, in the case where the business operator X who carries out the delivery business has a list of addresses for which re-delivery has been performed and the business operator Z has a list in which addresses and users are associated with each other, these lists are By combining them, it is possible to identify users who are frequently redistributed, and when such users purchase products at the online shopping mall, it is possible to realize efficient delivery by designating a time zone that the user can easily receive and shipping. Conceivable. However, if the business operator X does not register the list, it may not be possible to achieve efficient delivery.

Therefore, the information management device 10 executes the following processing in order to promote the entry of each business. First, the information management device 10 sets a predetermined reward for a predetermined company when another company registers information by introducing the predetermined company. For example, the information management apparatus 10 sets a predetermined remuneration for a predetermined business operator when another business operator, whose business type is similar to that of the predetermined business operator, registers information. That is, the information management device 10 sets a predetermined incentive for a business operator who has helped another business operator to enter.

For example, the information management device 10 requests the business operator A to introduce a business operator of the same type. Then, when the information management apparatus 10 receives the information registration from the business operator Y in the same industry as the business operator A by the introduction of the business operator A, the information management device 10 sets a reward for the business operator A. The reward may be a predetermined amount or may be set according to the amount and quality of the data registered by the business operator Y. For example, when the data registered by the business operator Y is data that is not similar to the data that has been registered up to that point, or is data that includes information of a type that has not been registered, the information management device 10 , The reward for the business operator A may be increased. Further, the information management device 10 may calculate the degree of contribution of the data registered by the business operator Y and set the reward according to the calculated degree of contribution by the same processing as the selection processing described later.

[1-1-4. Feedback from business operators]
Here, in the above-mentioned data management service, if the accuracy of the analysis result provided by the DS is not very good, the frequency of use by each business operator may decrease. Therefore, the information management device 10 may receive feedback from the business operator.

For example, the information management device 10 provides the business operator A with a model for making a prediction. Then, the information management device 10 requests the business operator A to provide feedback. In such a case, the information management device 10 receives registration of the actual measurement value from the business operator A. For example, when the information management apparatus 10 provides the business operator A with a model for predicting the number of users who will purchase a new product at a predetermined future date and time, the new product from the business operator A at a predetermined date and time Accept the number of users who have purchased as an actual measurement value (that is, correct answer data).

Such feedback can be useful for evaluating the accuracy of the model, and thus for evaluating the DS that created the model and improving the accuracy of the model. Therefore, the information management device 10 may set a predetermined incentive for the operator who registered the feedback. Further, the information management device 10 may evaluate the DS by using the actually measured value, or may provide the actually measured value to the DS and request improvement of the prediction accuracy of the model.

[1-1-5. About rewards]
Here, the content of the reward in the above-mentioned data management service can adopt an arbitrary aspect. For example, the information management device 10 may change the reward for the business operator who has registered the information used to create the analysis result, depending on the accuracy of the analysis result and the degree of contribution to the improvement in accuracy. Further, the information management device 10 may change the reward for the DS depending on the accuracy of the analysis result created by the DS and the like.

[1-2. About selection processing]
Next, an example of the selection process executed by the information management device 10 will be described with reference to FIG.

[1-2-1. Overview of selection process]
In the data management service described above, when the analysis result is provided to each business operator, the business operator receives a reward from the business operator. Such remuneration can be used not only as a resource for operating the data management service, but also as a resource for remuneration for the DS that created the analysis result and the business operator that registered the information used for creating the analysis result.

Here, a mode is conceivable in which each business is provided with a reward according to the degree of contribution of information. Therefore, the information management device 10 executes the following selection process. First, the information management device 10 receives the purpose of use of information registered by a plurality of businesses. Further, the information management device 10 estimates the effect on the purpose of use for each combination of information, and selects the information used for the purpose of use based on the estimated effect. Then, the information management device 10 determines the proportion of the remuneration to the plurality of businesses who have registered the information, based on the effect of the selected information on the purpose of use.

That is, the information management device 10 determines a combination of information that maximizes the effect for the purpose of use, estimates the effect for each combination of information in the determined combination, and uses each information based on the estimation result. Calculate the contribution to the purpose. Then, the information management device 10 determines the proportion of the reward to the business operator who has registered each piece of information, according to the calculated degree of contribution.

For example, the information management device 10 generates a combination of business operators who have registered information, and estimates the effect of information registered by the business operators included in the combination for each generated combination of business operators. To give a more specific example, the information management device 10 generates all combinations of businesses, and estimates the effect of information registered by the business with respect to the generated combinations. Note that the information management device 10 may generate a combination of subsets of information registered by a plurality of businesses, and estimate the effect of information included in the combination for each generated combination of subsets. The information management apparatus 10 estimates the effect of using the information and the subset registered by the business operators in the ascending order of the number of business operators and the number of subsets, and the estimated improvement rate of the effect is a predetermined threshold value. If it is below the threshold, the process of estimating the effect may be terminated.

Here, the effects of each combination of information include, for example, the accuracy of the analysis result when the information included in the combination is used (that is, the problem solving accuracy, the prediction accuracy, etc.), and the effect that the information has on the analysis result. Any degree can be adopted as long as it indicates the degree.

For example, when the purpose of use is related to advertisement, the information management device 10 can employ the improvement rate of CTR (Click Through Rate), the conversion rate, and the rate of profit improvement estimated in the future as an effect. When the purpose of use is related to the member business, the information management device 10 improves the customer acquisition effect rate, the ARPU (Average Revenue Per User) rate, and the total LTV (Life Time) by improving the customer retention rate. The rate of increase of Value) can be used as an effect. In addition, if the purpose of use is related to demand forecasting, the efficiency improvement rate for logistics, the rate of cost reduction such as personnel expenses, the rate of cost reduction due to the prevention of loss of sales opportunities, etc. can be adopted as effects. .. Note that the information management device 10 may use a plurality of the various effects described above in combination. That is, the information management device 10 can adopt an arbitrary degree as an effect as long as it is an effect according to the purpose of use and a degree indicating the effect of each information.

Then, when the effect is estimated for each combination of information, the information management device 10 selects, as the information used for the purpose of use, the information included in the combination having the maximum estimated effect among the combinations. To do. That is, the information management device 10 selects a combination of information estimated to have the maximum effect for a certain purpose of use. For example, the information management device 10 selects a business operator that has registered information included in a combination estimated to have the maximum effect for a certain purpose of use. Further, the information management device 10 selects a combination of subsets estimated to have the maximum effect for a certain purpose of use.

Subsequently, the information management device 10 sets the ratio of the reward to the business operator who registered each information, based on the difference in effect between the case where the information included in the selected combination is used and the case where the information is not used. .. More specifically, the information management device 10 determines the contribution degree of the business operator who has registered each piece of information based on the difference in the effect, and sets the reward ratio based on the determined contribution degree. Since the information management device 10 sets the ratio of the reward to the business operator who registered each information, based on the difference in effect between the case where the information included in the selected combination is used and the case where the information is not used. If so, the reward rate may be set by an arbitrary method. In the following description, the first method to the third method of setting the reward ratio will be described as an example.

For example, the information management device 10 calculates, as a first method, an effect when the information included in the selected combination is not used, as a reference effect. Then, the information management device 10 determines the remuneration rate for each business operator based on the difference between the effect and the reference effect when only the information registered by each business operator is used.

For example, the information management device 10 calculates, as a reference effect, the effect of the analysis result created using only the information registered by the business X for the purpose of use registered by the business X. Subsequently, the information management device 10 uses the information registered by the business operator X when the effect is maximized when the information registered by the business operators A to D is combined for the purpose of use registered by the business operator X. In addition, the effect of using the information registered by each business operator is calculated. That is, the information management apparatus 10 has the effect of using the information registered by the business X and the business A, the effect of using the information registered by the business X and the business B, and the business X. The effect of using the information registered by the business operator C and the effect of using the information registered by the business operator X and the business operator D are individually calculated.

Then, the information management device 10 calculates the difference between each calculated effect and the reference effect, and sets the calculated difference as the contribution degree of each business operator. Then, the information management apparatus 10 sets the ratio of the degree of contribution of each business operator A to D as the ratio of the reward allocated to each business operator A to D. For example, when the model using the information of the business operators A to D is provided to the business operator X who has registered the purpose of use, the information management device 10 provides a predetermined percentage of the reward provided by the business operator X. Allocate to businesses A to D. That is, the information management device 10 sets a reward for each of the businesses A to D based on the determined ratio, using the reward for providing the analysis result as a resource.

Here, as a second method, the information management device 10 uses each information based on the difference between the effect when the selected information is used and the effect when the information registered by each operator is not used. The proportion of reward to the person may be determined. For example, the information management device 10 calculates the effect of using the information registered by the business X and the business B to D as the effect of not using the information of the business A. Similarly, the information management device 10 calculates the effect when the information registered by the business X and the business A, C, and D is used as the effect when the information of the business B is not used, and the business When the effect of using the information registered by the business operator X and the business operators A, B, and D is calculated as the effect of not using the information of the business person C, and when the information of the business operator D is not used The effect of using the information registered by the business operator X and the business operators A to C is individually calculated as the effect of.

Further, the information management device 10 calculates the effect when all the information of the business operator X and the business operators A to D is used. In addition, the information management device 10 shows a difference between the effect when the information of each business operator A to D is not used and the effect when all the information of the business operator X and the business operators A to D is used. The absolute value is calculated as the degree of contribution of each business operator A to D. Then, the information management device 10 sets the calculated ratio of contributions as the ratio of remuneration distributed to each of the businesses A to D.

Here, it is conceivable that a great effect will occur when the information of a certain business operator is combined with the information of a specific business operator. However, the first method and the second method described above cannot realize the distribution of rewards in consideration of such a phenomenon. Therefore, the information management device 10 may execute the following process as a third method. For example, the information management device 10 generates a combination of a predetermined business operator and another business operator from a plurality of business operators who have registered the selected information. Further, the information management device 10 calculates, for each of the generated combinations, the difference between the effect when the business operator included in the combination registers and the effect when the selected information is not used. Further, the information management device 10 calculates the difference between the effect when the selected information is not used and the effect when only the information registered by the predetermined business operator is used. Then, the information management device 10 may determine the proportion of the reward to the predetermined business operator based on the calculated average value of the differences.

Hereinafter, an example of the third method will be described. In addition, in the following description, an example of a process of calculating the ratio of the reward to the business operator A will be described. For example, the information management apparatus 10 uses the first method to calculate the difference between the effect when the information registered by the business operator X and the business operator A is used and the reference effect as the first contribution degree. Subsequently, the information management apparatus 10 uses the second method to calculate the absolute value of the difference between the effect when only the information of the business operator A is not used and the effect when all the information is used as the second value. Calculated as the degree of contribution. The first contribution calculated in this way is the contribution of the business operator A when the data of one business operator is used, and the second contribution degree is the business when the data of three business operators is used. It is the contribution degree of person A.

Subsequently, the information management device 10 creates a combination of two businesses from the businesses A to D. Then, the information management device 10 calculates, for each generated combination, the effect of using the information registered by the business operator included in the combination, and calculates the difference between the calculated effect and the reference effect. Then, the information management device 10 divides the sum of the differences calculated for the combination including the business operator A by the sum of the differences calculated for all the combinations, and divides the value by the number of combinations including the business operator A. Is calculated as the third contribution degree. That is, the information management device 10 calculates the average value of the contribution degree of the business operator A when using the data of the two business operators.

Then, the information management device 10 calculates the average value of the calculated first contribution degree, second calculated contribution degree, and third calculated contribution degree, and based on the calculated average value, determines the proportion of remuneration for the business operator A. .. That is, the information management device 10 uses the information registered by the business operator A, and calculates the effect for all 2 ⁿ⁻¹ cases in which the information registered by another business operator is used and not used, Based on the calculated average value of the effects, the ratio of the reward to the business operator A is set.

In addition, the ratio of the remuneration distributed to each operator in the above-described first method to third method can be expressed by the following mathematical formula. For example, letting n be the combination of operators that maximizes the effect for a certain purpose from all operators, n can be expressed by the following equation (1). Here, V(N) in the equation (1) indicates a value when data of N operators is used.

Here, if the reward associated with the provision of the analysis result is V _all , and the proportion of V _all that is allocated to the business operator that registered the used information is d, the reward distributed to each business operator by the first method is as follows. Can be expressed by the equation (2), and the reward distributed to each business operator by the second method can be expressed by the following equation (3). In addition, V'(k) in Formula (3) shows the effect when the information of the business operator k among the business operators included in n is not used.

Here, the coefficient of contribution by the business operator k among the business operators included in n can be expressed by the following equation (4). Therefore, the reward distributed to the business operator k can be expressed by the following equation (5).

[1-2-2. Regarding an example of selection processing]
Next, an example of the selection process executed by the information management device 10 will be described with reference to FIG. In the following description, as an effect, an example of a process executed when the accuracy (for example, the prediction accuracy by the model) for achieving the purpose of use registered by the business operator X is adopted will be described.

First, the information management device 10 generates a combination of information registered by a plurality of businesses (step S1). Then, the information management device 10 estimates the accuracy of achieving the purpose of use for each combination when used for a predetermined purpose of use (step S2). Then, the information management device 10 selects a combination of businesses that maximizes accuracy (step S3). In the following description, it is assumed that the information management device 10 selects a combination including businesses A to D as a combination of businesses having the highest accuracy.

Then, the information management device 10 estimates the accuracy when each of the data of each company is used when determining the proportion of the reward to each company A to D using the first method (step S4). .. For example, the information management device 10 has an accuracy of “110” when the information registered by the business operator X and the business operator A is used, and a “120” accuracy when the information registered by the business operator X and the business operator B is used. The accuracy “130” when the information registered by the business X and the business C is used, and the accuracy “140” when the information registered by the business X and the business D is used are calculated.

Then, the information management device 10 sets the difference between the reference accuracy and each accuracy as the contribution of each business operator, and calculates the proportion of the reward based on the ratio of each contribution to the total contribution (step S5). .. For example, it is assumed that the information management device 10 calculates the accuracy “100” when only the information registered by the business operator X is used. In such a case, the information management apparatus 10 determines that the contribution degree of the business operator A is “10”, the contribution degree of the business operator B is “20”, the contribution degree of the business operator C is “30”, and the contribution degree of the business operator D is “40”. To calculate.

Here, the total of the contributions is “100”. Therefore, the information management device 10 divides the contribution degree of each of the businesses A to D by the total of the contribution degrees of “100” to give the proportion of the remuneration “10%” to the business person A to the business person B. The proportion of the reward to be distributed “20%”, the proportion of the reward to be distributed to the business operator C “30%”, and the proportion of the reward to be distributed to the business operator D “40%” are calculated.

On the other hand, the information management device 10 estimates the accuracy when each of the data of the business operators A to D is not used when determining the proportion of the reward to the business operators A to D by the second method (step S6). For example, the information management device 10 uses the accuracy “190” when using the information registered by the business operator X and the business operators B to D, and the information registered by the business operator X and the business operators A, C, and D. The accuracy "170" in the case of using the information, the accuracy "150" in the case of using the information registered by the business operator X and the business operators A, B, and D, and the information registered by the business operator X and the business operators A to C. The precision "130" when used is calculated.

Then, the information management device 10 calculates the difference between the accuracy when using the information of all the operators A to D and each accuracy, and calculates the proportion of reward based on the ratio of the difference (step S7). .. For example, it is assumed that the information management device 10 has calculated “200” as the accuracy when the information of the business operator X and all the business operators A to D is used. In such a case, the information management device 10 has a difference "10" between the accuracy "190" when the information of the business operator A is not used and the accuracy "200" when the information of all the business operators A to D is used. Is the degree of contribution of business operator A. Similarly, the information management device 10 calculates the contribution degree “30” of the business operator B, the contribution degree “50” of the business operator C, and the contribution degree “70” of the business operator D.

Here, the total of the contributions is “160”. For this reason, the information management apparatus 10 sets the ratio “6.25%” obtained by dividing the contribution degree “10” of the business operator A by the total “160” of the respective contribution degrees as the proportion of the reward distributed to the business operator A. To do. Similarly, the information management apparatus 10 allocates the reward “18.75%” to the business operator B, “31.25%” to the business operator C, and the business operator D. The proportion of the reward to be distributed “43.75%” is calculated.

Further, when the information management device 10 determines the proportion of the remuneration for each of the businesses A to D by the third method, the business to be processed among the businesses A to D is selected as a selected business, and the selected business is selected. The difference from the total increase in accuracy is calculated for all combinations of persons and business operators other than that, and the reward ratio is calculated based on the average value of the calculated differences (step S8). For example, the information management device 10 selects the business operator A as the selected business operator. In such a case, the information management apparatus 10 sets the reward “10%” for the business operator A calculated using the first method as the first contribution rate, and rewards the business operator B calculated using the second method. The ratio of “6.25%” is defined as the second degree of contribution.

Further, the information management device 10 generates all combinations of two businesses from the businesses A to D, and accuracy when using information registered by the business and the business X included in the generated combinations, The difference from the accuracy when only the information registered by the business operator X is used is calculated. Then, the information management device 10 divides the sum of the differences in the combination including the selected business operator A by the total sum of the differences, and divides the divided value by the number of combinations including the selected business operator A. The calculated value “13.33%” is calculated as the third contribution degree. Then, the information management device 10 sets the average value “9.86%” of the first contribution degree to the third contribution degree as the proportion of the reward to the business operator A that is the selected business operator.

[1-3. About the estimation process provided by the information management device]
Next, an example of the estimation process executed by the information management device 10 will be described with reference to FIG.

[1-3-1. Outline of estimation process provided by information management device]
Here, in the above-mentioned data management service, if information that improves the accuracy of the analysis result is not registered, it is considered that the accuracy in information distribution cannot always be optimized. Therefore, the information management device 10 executes the following estimation process. First, the information management device 10 manages information registered by a plurality of businesses. The information management device 10 also receives the purpose of using the information from the user. Then, the information management device 10 estimates the business operator who owns the information of the type corresponding to the purpose of use.

As a result, the information management device 10 can request the estimated business operator to provide information corresponding to the purpose of use, and can improve the accuracy of analysis to reach the purpose of use. Note that the information management device 10 not only requests the business operator who presumes the registration of the information corresponding to the purpose of use, but also requests the business operator to provide the permission to use the registered information, for example. Good. In addition, for example, when the content of the purpose of use is prediction using information, the information management device 10 may estimate a business operator who owns information of a type useful for the prediction.

Further, in the above-mentioned data management service, it can be said that the information of the business operator Z is available in principle. Therefore, the information management device 10 may estimate the type of information that can accurately achieve the purpose of use when combined with the information owned by the business operator Z, and may estimate the business operator who owns the information of the estimated type. ..

Further, when the information provided by the estimated business operator is provided for the corresponding usage purpose, the information management device 10 may set a predetermined reward for the business operator. For example, when the analysis result created using the information provided by the company is a model, the information management device 10 may set a reward for the company based on the correct answer rate of the created model. ..

Here, the information management device 10 calculates the degree of contribution of the information provided by the business operator to the purpose of use by the same calculation method as the selection processing described above, and rewards the business operator according to the calculated degree of contribution. May be set. That is, the information management device 10 sets the reward for the business operator based on the difference between the effect when the provided information that is the estimated information provided by the business operator is used and the effect when the information is not used. Good.

Here, the information management apparatus 10 becomes the registration source of the purpose of use, the analysis result generated by the predetermined DS in accordance with the purpose of use based on the information registered by a plurality of businesses, as in the above-described presentation process. May be provided to businesses. In such a case, the information management device 10 may set the reward according to the accuracy of the analysis result in the DS. Further, when the information management apparatus 10 receives the provision of the actual measurement information corresponding to the analysis result from the business operator to whom the analysis result is provided, the information management apparatus 10 may set a predetermined reward for the business operator.

[1-3-2. About an example of the estimation process provided by the information management device]
Hereinafter, an example of the estimation process executed by the information management device 10 will be described with reference to FIG. For example, the information management device 10 accepts the purpose of use from the business operator B (step S1). In such a case, the information management device 10 estimates the type of information useful for the purpose of use (step S2). For example, in the example illustrated in FIG. 3, the information management device 10 receives from the business operator B a purpose of use such as “forecasting sales of product A”. The information management device 10 also accepts the designation of the data indicated by “DID#2” as the usable data that can be provided by the business operator B for the purpose of use. In such a case, the information management device 10 estimates the type of information necessary to realize the “marketing forecast of the product A” by combining with the “DID#2”.

For example, the information management device 10 determines the relationship between the purpose of use registered in the past and the type of information used by the DS to meet the purpose of use (for example, the user's attribute or purchase history). Generate a trained model. Then, the information management device 10 may use the generated model to estimate the type of information required to satisfy the purpose of use. Further, the information management device 10 may provide the purpose of use to the DS and employ the type of information registered as necessary information by the DS as the estimation result. For example, in the example shown in FIG. 3, the information management device 10 is a type of information (hereinafter, referred to as “estimated information type”) necessary to satisfy the purpose of use of the content such as “sales forecast of product A”. The "food purchase history", "user attribute", "posting history on SNS", etc. are estimated.

Next, the information management device 10 identifies the information of the type for which the information is not registered by the business operator among the estimated information types (step S3). For example, the information management device 10 identifies the type of information registered in the data management service, and compares the identified type with the estimated information type to confirm that the “post history to SNS” is not registered. Identify.

Then, the information management device 10 estimates the business operator holding the specified type of information (step S4). For example, the information management device 10 holds the businesses of the businesses A to D in advance. Then, the information management device 10 selects a business operator in a business type that is highly related to the specified type. For example, in the example illustrated in FIG. 3, the information management device 10 selects the business operator D whose business type is “SNS”.

Then, the information management device 10 requests the selected business operator D to register information (step S5). Further, when the information management apparatus 10 receives the registration of the information from the business operator D (step S6), the information management apparatus 10 is a model satisfying the purpose of use generated by the above-described presentation process and the information registered by the business operator D. The model created using is provided to the business operator B (step S7). After that, the information management device 10 provides the enterprise D with a predetermined reward for registering the information and using the information (step S8).

[1-4. Regarding the provision processing provided by the information management device]
Next, an example of the providing process executed by the information management device 10 will be described with reference to FIG.

[1-4-1. Overview of provision processing provided by information management device]
For example, in the above-described data management system, the analysis results satisfying the purpose of use are created using the information registered by a plurality of businesses, and the created analysis results are provided. However, the information held by each business operator is often not the same in format.

For example, the business operator A sets an item name such as "sex" in the information indicating the gender of the user, and the business operator B sets an item name such as "sex" in the information indicating the gender of the user. It is possible that Further, the business operator B stores a character string such as “male” or “female” as the information indicating the gender of the user, and the business operator C stores the numerical value “1” indicating male as the information indicating the gender of the user. It is conceivable to set a numerical value “2” that indicates “or female”. As described above, in the information registered by each business operator, different item names may be set for the same type of information, or the format for expressing the same type of information may be different.

When such information is sorted, the list of information by DS etc. is improved, but when the operator wants to reuse the registered information, the information in a different format from that at the time of registration is provided. There is a fear.

Therefore, the information management device 10 executes the following providing process. First, the information management device 10 manages information registered by a plurality of businesses and having individual formats, in a state in which the formats are held. When the information management device 10 receives the information reference request, the information management device 10 provides the reference information in a predetermined format. For example, the information management device 10 manages information of a plurality of formats including a plurality of values in which an item name indicating a type is set, and in which different item names are set for values of the same type. .. When the information management device 10 receives the item name of the information to be referred to, the information management device 10 extracts the value of the type indicated by the received item name from the managed information, and provides the extracted value.

To give a more specific example, the information management device 10 accepts a value to be a search query, an item name of a value to be a search query, and an item name of a value to be a reference from DS or the like. In such a case, the information management device 10 searches the managed information for information in which the value of the type indicated by the item name of the value serving as the search query matches the value serving as the search query, and the searched information is searched. From, the value of the type indicated by the item name of the value to be referenced is extracted, and the extracted value is provided.

Here, it is possible that the contents of information registered by a plurality of businesses are duplicated. Therefore, when a plurality of pieces of information in which the value of the type indicated by the item name of the value serving as the search query matches the value serving as the search query is registered, the information management device 10 selects among the values included in the plurality of pieces of information. Each value of the type indicated by the item name of the value to be referred to is extracted, and one value based on the plurality of extracted values is provided.

For example, the information management apparatus 10 determines the number of pieces of information having the same reference target value among a plurality of pieces of information in which the value of the type indicated by the item name of the value serving as the search query matches the value serving as the search query. Counting may be performed for each value to be referred, and the value having the highest counted number may be provided. For example, in the information management device 10, when there are five pieces of information having a reference target value of “male” and one piece of information having a reference target value of “female”, the value “ Men may be provided. If there is one piece of information whose reference target value is “male” and the reference target value in other information is “null” (that is, it is not registered), The value "male" may be output.

[1-4-2. About setting the charge according to the format]
Here, the information management device 10 may set a usage fee for the data management service for each business operator who has registered the information. At this time, the information management device 10 determines the usage charge according to the difference between the format of the information registered by each business operator and the format in which the information registered by each business operator is provided to another business operator or DS. You may increase or decrease. For example, when the format of the information received from the business operator is the same as the format in which the information is provided, the information management device 10 sets a fee of a predetermined amount to the business operator and saves the information received from the business operator. When the format and the format for providing the information are different, the operator may be charged with a larger amount than the predetermined amount.

Further, the information management device 10 may set a charge to the business operator according to the degree of coincidence between the format of the information received from the business operator and the format when the information is provided. For example, the information management device 10 calculates the degree of coincidence between the format of information received from the business operator and the format in which the information is provided, and the higher the calculated degree of coincidence, the higher the degree of setting for the business operator. You may reduce the charge.

Further, when referring to information registered by another business operator in the data management service, the information management device 10 sets a usage fee for the business operator referring to the information. In such a usage fee, the information management device 10 may increase the usage fee when the format of the registered information is different from the format in which the information is provided. For example, when the format of the information to be managed is the same as the format of the information to be provided, the information management apparatus 10 sets a charge of a predetermined amount to the recipient of the information and the format of the information to be managed and the information to be provided. If the format is different from the above format, a fee larger than a predetermined amount may be set for the information providing destination.

[1-4-3. Regarding an example of the providing process provided by the information management device]
Hereinafter, an example of the providing process executed by the information management device 10 will be described with reference to FIG. For example, the information management device 10 receives registration of information from the business operator A (step S1). Further, the information management device 10 accepts registration of information from the business operator B (step S2). In such a case, the information management device 10 manages the registered information as it is without changing the format (step S3).

For example, in the example illustrated in FIG. 4, the information management apparatus 10 adds the item name “user ID” to the user identifier and the item name “sex” to the information indicating the user's gender. Then, the registration of the information DA in which the item name “purchase history” is set for the information indicating the purchase history of the user is accepted from the business operator A. Further, the information management apparatus 10 is provided with the item name “user ID” for the user's identifier, the item name “sex” for the information indicating the gender of the user, and the purchase history of the user. The registration of the information DB in which the item name “purchased product” is set for the indicated information is accepted from the business operator B.

Subsequently, the information management device 10 accepts the search query from the business operator A (step S4). In such a case, the information management device 10 identifies the item name corresponding to the type of information indicated by the search query, and extracts the information of the identified item name (step S5). For example, it is assumed that the information management device 10 receives a search query Q1 including a key item “user ID”, a key value “user#1”, and an acquisition item “sex” from the business operator A. In such a case, the information management device 10 identifies the item or the like to be searched according to the conversion table CT set in advance.

For example, the information management device 10 refers to the conversion table CT and identifies an item corresponding to the key item “user ID”, that is, an item name given to information of the same type as the key item. For example, in the example shown in FIG. 4, the information management device 10 specifies “user ID” as the item name corresponding to the key item. Further, the information management device 10 refers to the conversion table CT and identifies the item “sex” corresponding to the acquired item “sex”.

As a result, the information management device 10 sets the search query Q1 in which the key item is “user ID” or “user ID”, the key value is “user#1”, and the acquisition item is “gender” or “sex”. The information registered by each business operator is searched for. That is, the information management apparatus 10 uses the conversion table CT to search for information that matches the intention of the search query Q1 from a plurality of pieces of information having different formats.

For example, in the example illustrated in FIG. 4, the information management apparatus 10 identifies a record in which the value of the item name “user ID” is “user#1” from the information DA, and the item name of the identified records is The value "null" which is "gender" is specified. In addition, the information management apparatus 10 identifies from the information DB a record in which the value of the item name “user ID” is “user#1”, and of the identified records, the value “2” in which the item name is “sex”. Is specified. As a result, the information management device 10 selects the value “2” as the information provided to the search query Q1.

Further, the information management device 10 identifies the intention of the value “2” in which the item name is “sex” in the information DB. Such identification is performed, for example, along with the registration in the information DB, such that the value “2” of the item name “sex” is “female” and the value “1” of the item name “sex” is “male”. Is accepted from the business operator B and a conversion table in which the value “1” of the item name “sex” is associated with “male, and the value “2” is associated with “female” is created. Then, the information management device 10 generates the character string “female” indicating the intention of the selected value “2” and provides the generated character string “female” to the business operator A as a search result (step S6). .. For example, the information management device 10 provides the business operator A with the key value “user#1” and the character string “female”.

[1-5. Calculation process provided by information management device]
Next, an example of the calculation process executed by the information management device 10 will be described with reference to FIG.

[1-5-1. Outline of calculation processing provided by information management device]
For example, in the above-described data management system, each DS creates an analysis result that satisfies the purpose of use and provides the created analysis result. However, in such a data management system, it may be difficult to appropriately set the reward for the DS. For example, when a reward is set according to the analysis accuracy, a large amount of reward is set for the DS that has the highest analysis accuracy but takes the longest time to provide the analysis result.

Therefore, the information management device 10 executes the following calculation process. First, when the information management apparatus 10 accepts the purpose of use of information registered by a plurality of businesses, the information management apparatus 10 presents the purpose of use to a plurality of DSs that analyze information according to the purpose of use. Then, the information management device 10 calculates the reward for each DS according to the order in which the DS provided the analysis result and the accuracy of each analysis result. For example, the information management device 10 calculates the ratio of the predetermined reward allocated to each DS according to the order in which each DS provides the analysis result and the accuracy of the analysis result, and based on the calculated ratio. Then, the reward for each DS is calculated.

For example, the information management apparatus 10 calculates a reward based on the difference between the accuracy of the analysis result by the DS and a predetermined accuracy, as the reward for the DS that first provided the analysis result. For example, the information management device 10 uses the accuracy of the model when a model that satisfies the purpose of use is created based on only the information that the business operator who registered the purpose of use has, as the reference accuracy. Then, when the accuracy of the model provided first exceeds the reference accuracy, the information management apparatus 10 sets the difference between the reference accuracy and the accuracy of the model as the contribution degree of the DS that provided the model. ..

For example, the information management device 10 compares the accuracy of the analysis result by the DS with the accuracy of the analysis result provided earlier than the analysis result by the DS as a reward for the DS that provided the analysis result after the second. Calculate the reward based on. For example, when the accuracy of the analysis result by the DS that has provided the second and subsequent analysis results is worse than the accuracy of all the analysis results provided earlier, the information management device 10 sets the reward for that DS to 0. To do. Further, when the accuracy of the analysis result by the DS that has provided the second and subsequent analysis results is better than the accuracy of all the analysis results previously provided, the information management device 10 determines that all the previously provided analysis results have been obtained. The analysis result with the highest accuracy among the analysis results is specified, and the reward is calculated based on the difference between the accuracy of the specified analysis result and the accuracy of the analysis result by the DS.

[1-5-2. Regarding an example of calculation processing provided by the information management device]
Hereinafter, an example of the calculation process executed by the information management device 10 will be described with reference to FIG. In the following description, an example in which a model satisfying the purpose of use is provided by DS1 to DS4 for the purpose of use of a certain business operator will be described.

For example, the information management device 10 receives registration of information from the business operator (step S1). In such a case, the information management device 10 presents the purpose of use to the DS (step S2). Then, when the information management device 10 receives the provision of the model created by each DS (step S3), the information management device 10 provides the provided model to the business operator (step S4). Then, the information management device 10 receives the offer of the reward accompanying the offer of the model from the business operator (step S5).

Here, the information management device 10 specifies the accuracy of each model (step S6). For example, the information management apparatus 10 has a model accuracy “108” created by DS1, a model accuracy “103” created by DS2, a model accuracy “110” created by DS3, and a model accuracy “110” created by DS4. 105” is specified.

Next, the information management device 10 specifies the order in which each model is provided. For example, when the models are provided in the order of DS4, DS1, DS2, and DS3, the information management apparatus 10 has the order “second” in which DS1 provides the model and the order “third” in which DS2 provides the model, Identify the order "fourth" that DS3 provided the model and the order "first" that DS4 provided the model.

Then, the information management device 10 calculates the proportion of the reward provided to each DS, based on the contribution degree according to the accuracy of each model and the order of provision (step S8). For example, it is assumed that the information management device 10 calculates the reference accuracy and calculates the accuracy “100”. In such a case, the information management device 10 sets the value “5” obtained by subtracting the reference accuracy “100” from the accuracy “105” of the DS4 model provided first as the contribution degree of the DS4. That is, the information management device 10 sets the contribution degree for the DS4 based on the rate of increase in accuracy according to the DS4 model. Note that, for example, when the accuracy of the model of DS4 is lower than the reference accuracy, the degree of contribution to DS4 may be “0”.

Subsequently, the information management apparatus 10 compares the accuracy “108” of the DS1 model provided second with the reference accuracy and the accuracy “105” of the DS4 model provided first. Here, the accuracy “108” of the DS1 model provided second is higher than the accuracy and the reference accuracy of the DS4 model provided earlier than that. Therefore, the information management device 10 sets the value “3” obtained by subtracting the accuracy “105” of the previously provided DS4 model from the accuracy “108” of the DS1 model as the contribution degree of DS1.

Subsequently, the information management apparatus 10 compares the accuracy “103” of the DS2 model provided third with the accuracy “108” of the DS1 model having the highest accuracy of the models previously provided. .. Here, the accuracy “103” of the DS2 model provided third is lower than the accuracy “108” of the DS1 model. Therefore, the information management device 10 sets the contribution degree of DS2 to “0”.

Subsequently, the information management device 10 compares the accuracy “110” of the DS3 model provided fourth with the accuracy “108” of the DS1 model having the highest accuracy among the models previously provided. .. Here, the accuracy “110” of the DS3 model provided fourth is higher than the accuracy “108” of the DS1 model. Therefore, the information management device 10 sets the value “2” obtained by subtracting the accuracy “108” of the DS1 model from the accuracy “110” of the DS3 model as the contribution degree of the DS3.

Then, the information management device 10 sets the ratio of the contribution degree of each DS1 to DS4 as the ratio of the reward provided to each DS1 to DS4. For example, the information management device 10 extracts a part of the reward received in step S5 as the total amount of the reward to be provided to each DS1 to DS4. Then, the information management device 10 allocates 50% to the DS4, 30% to the DS1 and 20% to the DS3 of the total amount of the extracted reward.

In the above example, the reward for DS2 is “0”, but the embodiment is not limited to this. For example, when the accuracy of the created model exceeds the reference accuracy, the information management device 10 sets a predetermined basic reward for the DS for which the model was created, and further, the additional reward distributed by the above-described calculation process. May be set.

[2. Configuration of information management device]
Hereinafter, an example of the functional configuration of the information management device 10 described above will be described.

The communication unit 20 is realized by, for example, a NIC (Network Interface Card) or the like. The communication unit 20 is connected to the network N in a wired or wireless manner, and transmits/receives information to/from the web server 100, the enterprise server 200, and the DS terminal 300.

The storage unit 30 is realized by, for example, a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory (Flash Memory), or a storage device such as a hard disk or an optical disk. In addition, the storage unit 30 includes a business entity database 31, a DS database 32, a registration information database 33, a purpose database 34, a model database 35, and a conversion table 36 (hereinafter sometimes collectively referred to as “each database 31 to 36”). Memorize Hereinafter, an example of information registered in each of the databases 31 to 36 will be described with reference to FIGS. 7 to 12.

In the business entity database 31, various kinds of information regarding businesses are registered. For example, FIG. 7 is a diagram illustrating an example of the business entity database according to the embodiment. In the example shown in FIG. 7, in the business entity database 31, “business entity ID”, “business type”, “business category”, “registration information”, etc. are associated and registered. In addition to the information shown in FIG. 7, arbitrary information about a business may be registered in the business database 31.

Here, the "business operator ID" is an identifier for identifying the business operator. The "industry" is information indicating the type of product or service provided by the business operator, that is, the business operation of the business operator. In addition, the “business category” is information indicating the business category such as whether the business provides goods and services by mail order, whether they are provided at stores, and the like. The "registration information" is information indicating whether or not the business operator has registered the information in the data management service.

For example, in the example shown in FIG. 7, in the company database 31, a company ID “company A”, a business type “cosmetics”, a business type “mail order”, and registration information “present” are registered in association with each other. Such information indicates that the business type of the business indicated by the business ID “business A” is the business that sells “cosmetics”, the business category that sells “cosmetics” through “mail order”, and the data is stored in the data management service. Indicates that is registered.

Information on the DS is registered in the DS database 32. For example, FIG. 8 is a diagram showing an example of the DS database according to the embodiment. In the example shown in FIG. 8, "DSID", "DS information", "affiliation", "provided history", etc. are registered in the DS database 32 in association with each other. In addition to the information shown in FIG. 8, arbitrary information regarding the DS may be registered in the DS database 32.

Here, "DSID" is an identifier for identifying a DS. Further, the “DS information” is various kinds of information regarding the DS, such as the name, age, and history of the DS. The “affiliation” is information indicating the affiliation of the DS, and is information indicating, for example, whether the DS belongs to the business operator Z that operates the data management service. The “provided history” is information indicating the history of analysis results created and provided by the DS. In the example shown in FIG. 8, conceptual values such as “DS#1”, “DS information #1”, and “model #1” are shown, but in reality, numerical values or character strings for identifying DS, The character string indicating the DS information, the analysis result created and provided by the DS, and the like are registered.

For example, in the example shown in FIG. 8, information such as DSID “DS#1”, DS information “DS information #1”, affiliation “internal”, and provision history “model #1” is associated and registered in the DS database 32. Has been done. In such information, the DS information indicated by the DSID “DS#1” is “DS information #1”, belongs to the business operator Z, and created and provided the model indicated by “model #1” in the past. Indicate the effect.

In the registration information database 33, information registered by each business operator, that is, information registered in the data management service is registered. For example, FIG. 9 is a diagram illustrating an example of the registration information database according to the embodiment. In the example shown in FIG. 9, the registration information database 33 has information such as “company ID”, “data ID”, “subset ID”, “user ID”, “sex”, and “purchase history”. Are registered in association with each other. Further, as shown in FIG. 9, information registered by each business is managed individually in the registration information database 33 without changing the format from the time of registration. In addition to the items shown in FIG. 9, information in which arbitrary items set by each business operator are set may be registered in the registration information database 33, and the value of each item is different for each business operator. It may be set.

For example, the "business operator ID" is an identifier indicating the business operator who has registered the information. The “data ID” is an identifier that identifies information registered by the business operator. For example, when a certain business operator registers the first information and then registers the second information, individual data IDs are given to the first information and the second information, respectively. The “subset ID” is an identifier indicating a subset to which the data belongs, and is information that can be arbitrarily set by the business operator. The business operator ID, the data ID, and the subset ID are information that is automatically added when the business operator registers data, and the information registered by the business operator, that is, the information acquired by the business operator is For example, it corresponds to a set of information such as “user ID”, “sex”, and “purchase history”.

For example, the “user ID” is an identifier of a user who has been provided with the service of the business indicated by the business ID. The "sex" is the sex of the user indicated by the associated "user ID", and the "purchase history" is information indicating the purchase history of the user.

Here, in the example shown in FIG. 9, in the registration information database 33, the business ID “business A”, the data ID “DID#1”, the subset ID “subset #1”, and the user ID “user#1”. , Information such as sex “null” and purchase history “purchase history #1” are registered in association with each other. Such information is information registered by the business operator indicated by the business operator ID “business operator A”, and belongs to the subset indicated by the subset ID “subset #1” in the data ID “DID#1”. Indicates that the record is registered. Further, such a record has items such as “user ID”, “gender”, and “purchase history”, and values such as “user#1”, “null”, and “purchase history #1” are stored. Indicates.

Information on the purpose of use is registered in the purpose of use database 34. For example, FIG. 10 is a diagram illustrating an example of the usage purpose database according to the embodiment. In the example shown in FIG. 10, in the usage purpose database 34, information such as “usage purpose ID”, “usage purpose (issue)”, “user company”, “usable data”, and “reward” are registered in association with each other. Has been done. In addition to the information shown in FIG. 10, any information related to the purpose of use may be registered in the purpose-of-use database 34.

Here, the “purpose of use ID” is an identifier for identifying the purpose of use. The “purpose of use (problem)” is information indicating a problem, a prediction, an analysis content, etc. registered as a purpose of use. Further, the “utilization business operator” is the business operator ID of the business operator who has registered the purpose of use. In addition, “usable data” is information that can be used to create an analysis result, among the information possessed by the business operator that registered the purpose of use. Further, the “reward” is information indicating a reward for creating and providing an analysis result that satisfies the associated “purpose of use (issue)”, and is a reward set by the business operator who registered the purpose of use.

For example, in the example shown in FIG. 10, the purpose-of-use database 34 has a purpose-of-use ID “U#1”, a purpose-of-use (issue) “predictor of new cosmetics purchaser”, a business operator “business operator A”, and available Information such as data “DID#1” and reward “reward R1” are registered in association with each other. Such information is data that can be provided by "business operator A" because "business person A" has registered "predictor of new cosmetics purchaser" as the use purpose indicated by the usage purpose ID "U#1". Is data indicated by “DID#1”, and indicates that the reward for creating and providing the analysis result satisfying the purpose of use is the reward “reward R1”. Note that in the example shown in FIG. 10, conceptual values such as “U#1” and “reward R1” are described, but in reality, numerical values or character strings for identifying the purpose of use, numerical values indicating the amount of remuneration, etc. be registered.

The model that is the analysis result is registered in the model database 35. For example, FIG. 11 is a diagram showing an example of the model database according to the embodiment. In the example shown in FIG. 11, “model ID”, “DSID”, “purpose of use ID”, “provision date/time”, “accuracy”, “usage information” and the like are associated and registered in the model database 35. .. In addition to the information shown in FIG. 11, arbitrary information about the model created as an analysis result may be registered in the model database 35.

Here, the "model ID" is an identifier for identifying the model. In addition, “DSID” is a DSID that identifies the DS that created and provided the model. In addition, "use purpose ID
Is a usage purpose ID indicating a usage purpose that the model satisfies. Further, the “providing date and time” is information indicating the date and time when the model was provided from the DS. The "accuracy" is information indicating the accuracy of the model. Further, the “utilization information” is the data ID of the information used to create the model. Note that in the example shown in FIG. 11, a conceptual value such as “provided date and time ID” is described, but in reality, a character string indicating the provided date and time will be registered.

For example, in the example shown in FIG. 11, in the model database 35, the model ID “model #1”, the DSID “DS#1”, the usage purpose ID “U#1”, the provision date/time “provision date/time #1”, and the accuracy “ 105” and usage information “DID#1, DID#2...” Are associated and registered. Such information indicates that the model indicated by the model ID “model #1” is created by the DS indicated by the DSID “DS#1”, and the model satisfies the usage purpose ID “U#1”. In addition, such information is provided at the date and time indicated by the provision date and time "Provision date and time #1", the accuracy value for the purpose of use is "105", and the use information "DID#1, DID#2... -" indicates that the model is created using the information.

The conversion table 36 is a table showing conversion rules for item names and values. For example, FIG. 12 is a diagram showing an example of the conversion table according to the embodiment. In the example shown in FIG. 12, information such as “item”, “corresponding item”, and “conversion rule” is associated and registered in the conversion table 36. In addition to the information shown in FIG. 12, various conversion rules adopted in the providing process may be registered in the conversion table 36.

Here, the "item" is information indicating a key item or an acquisition item indicated by the search query. The “corresponding item” is information indicating an item name given to a value of the same type as the associated “item” (that is, a value having the same intention). Further, the “conversion rule” is information indicating a rule when converting a value. In the example shown in FIG. 12, a conceptual value such as “conversion rule #1” is described, but in reality, a character string indicating how to convert the value, a conditional expression, or the like is registered.

For example, in the example shown in FIG. 12, in the conversion table 36, a pair of a corresponding item “sex” and a conversion rule “conversion rule #3 (1: male, 2: female)” for the item “sex”, and A pair of the corresponding item “sex information” and the conversion rule “conversion rule #4” is registered in association with each other. When the key item is "gender", such information can be selected from the information registered by each business operator, and the item name can be "gender", "sex", or "gender information". Indicates that the value corresponding to the key value is searched. Further, such information indicates that, when referring to a value whose item name is “sex”, a value corresponding to the key value is searched according to “conversion rule #3”. For example, in such information, the value “1” assigned the item name “sex” is equivalent to the value “male” assigned the item name “sex”, and the item name “sex” is assigned. It indicates that the value “2” is equivalent to the value “female” to which the item name “sex” is assigned.

Returning to FIG. 6, the description will be continued. The control unit 40 is, for example, a controller, and various programs (an example of a notification program) stored in a storage device inside the information management device 10 by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. (Corresponding to) is executed by using the RAM as a work area. The control unit 40 is a controller, and is realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

As shown in FIG. 6, the control unit 40 includes a presentation control unit 50, a selection control unit 60, an estimation control unit 70, a provision control unit 80, and a calculation control unit 90 (hereinafter collectively referred to as “each control unit 50 to 90”). May be). Here, the presentation control unit 50 realizes the above-described presentation processing. The selection control unit 60 also implements the above-described selection processing. The estimation control unit 70 also implements the above-described estimation process. The provision control unit 80 also implements the above-described provision processing. The calculation control unit 90 also realizes the above-described calculation processing.

Hereinafter, an example of the functional configuration of each of the control units 50 to 90 will be described with reference to FIGS. FIG. 13 is a diagram illustrating a configuration example of the presentation control unit according to the embodiment. FIG. 14 is a diagram illustrating a configuration example of the selection control unit according to the embodiment. FIG. 15 is a diagram illustrating a configuration example of the estimation control unit according to the embodiment. FIG. 16 is a diagram illustrating a configuration example of the provision control unit according to the embodiment.

First, an example of the functional configuration of the presentation control unit 50 will be described with reference to FIG. As shown in FIG. 13, the presentation control unit 50 includes a management unit 51, a reception unit 52, a presentation unit 53, a setting unit 54, and an analysis result providing unit 55. The management unit 51 manages information registered by a plurality of businesses. More specifically, the management unit 51 manages information registered by a plurality of businesses and having individual formats, while maintaining the formats. For example, when the management unit 51 receives the information to be registered from the business operator, it gives the business operator ID and the data ID without changing the format, that is, without converting the item name or the value. It is registered in the registration information database 33 as it is.

Here, each business operator may give different values to the same event or set different item names for such values. As a result, the management unit 51 manages information in a plurality of formats including a plurality of values in which item names indicating types are set and different item names are set for values of the same type. It will be. In addition, when the management unit 51 receives a reference request for information registered by itself from the business operator, the management unit 51 provides the information to the business operator.

Further, the management unit 51 provides the information registered by the business operator to the DS. For example, when the management unit 51 receives a request to provide information from the DS2, the management unit 51 identifies from the registration information database 33 the business operator that has registered the information to be provided, and whether or not it is possible to provide the specified business operator with information. To inquire. At this time, the management unit 51 may notify the content of the purpose of use, the information of the operator who registered the purpose of use, the information of the DS, and the like. Then, the management unit 51 provides, to the DS, only the information that has been approved by the registered business operator among the information to be provided.

The reception unit 52 receives the purpose of use of information registered by a plurality of businesses from any user. For example, when the reception unit 52 receives the content of the purpose of use, the specification of the usable data, the content of the reward, etc. from the business operator, the content of the received purpose of use, the DID indicating the usable data, and the reward are stored in the utilization purpose database 34. Register with. For example, the reception unit 52 receives registration of a predetermined event to be predicted as the content of the prediction using the information. In such a case, the information management device 10 requests each DS to create a model for predicting a predetermined event.

When the presentation unit 53 accepts the purpose of use of the information registered by a plurality of businesses, the presenter 53 presents the purpose of use to a plurality of DSs that analyze the information according to the purpose of use. For example, the presentation unit 53 presents the usage purpose registered in the usage purpose database 34 in response to the presentation request from each DS. Here, the presentation unit 53 presents the purpose of use to the event person who registered the information and the DS different from the business operator who manages the information registered by a plurality of businesses. That is, the presentation unit 53 presents the purpose of use to not only the DS1 belonging to the business operator Z but also the external DS2 and requests the creation of the analysis result.

The setting unit 54 sets a predetermined reward for the DS when the analysis result is provided by the DS. Further, when the analysis result is provided, the setting unit 54 sets a predetermined reward for the business operator who has registered the information used for creating the analysis result.

For example, when the model created from the DS is provided to the business operator, the setting unit 54 allocates a part of the reward set by the business operator together with the purpose of use to the DS. For example, the setting unit 54 may set the reward according to the accuracy of the provided model in the DS, or may set the reward in the proportion consulted from the DS in advance. The setting unit 54 may also set the reward based on the result of the calculation process executed by the calculation control unit 90.

In addition, the setting unit 54 may set a predetermined reward for a predetermined company when another company registers information by introducing the predetermined company. That is, the setting unit 54 may set a predetermined reward when a business operator who has registered information in the data management service invites another business operator and the other business operator registers the information. For example, the setting unit 54 may set a predetermined reward for a predetermined business operator when another business operator whose business type is similar to that of the predetermined business operator registers information.

Further, for example, in the setting unit 54, the business operator who has registered the information in the data management service solicits the business operator estimated by the estimation processing executed by the estimation control unit 70, and the estimated business operator registers the information. If you do, you may increase the remuneration amount for the business operator who registered the information in the data management service. That is, when the new information required to create the analysis result is registered, the setting unit 54 may increase the remuneration amount for the business operator who registered the information.

The analysis result providing unit 55 provides the business operator with the analysis result generated by the predetermined DS in accordance with the purpose of use, based on the information registered by the plurality of businesses. For example, the analysis result providing unit 55 uses a model satisfying the purpose of use registered by the business operator A, that is, a model learned using information registered by a plurality of business operators or a model for predicting a predetermined business. When the DS2 creates the model, the model created by the DS2 is provided to the business operator A. Further, the analysis result providing unit 55 registers in the model database 35 the information of the model created by the DS2, the provision date and time, the information used for creating the model, and the like in association with the DSID of the DS2.

Next, an example of the functional configuration of the selection control unit 60 will be described with reference to FIG. As illustrated in FIG. 14, the selection control unit 60 includes an effect estimation unit 61, a selection unit 62, a determination unit 63, and a setting unit 64.

The effect estimation unit 61 estimates the effect for the purpose of use for each combination of information. For example, the effect estimation unit 61 generates a combination of business operators who have registered information, and estimates the effect of information registered by the business operators included in the combination for each generated combination of business operators. For example, the effect estimation unit 61 estimates the effect of the information registered by the business operators included in the combination for all the business operator combinations. The effect estimation unit 61 may generate a combination of subsets of information registered by a plurality of businesses, and estimate the effect of information included in the combination for each generated combination of subsets.

For example, the effect estimation unit 61 refers to the model database 35, selects a model to be processed from the models provided to the business operator, and identifies the business operator who has registered the information used to create the selected model. Identify. Then, the effect estimation part 61 produces|generates all the combinations of the specified business operators, and estimates the precision at the time of creating a model for every combination of the produced business operators using the information registered by the business operator.

The selection unit 62 selects information used for the purpose of use based on the estimated effect. More specifically, the selection unit 62 selects the information included in the combination that maximizes the estimated effect, as the information used for the purpose of use. For example, the selection unit 62 selects a combination of businesses with the highest accuracy estimated by the effect estimation unit 61.

The deciding unit 63 decides the proportion of remuneration for a plurality of businesses that have registered information, based on the effect of the selected information on the purpose of use. For example, the determination unit 63 sets the reward for the business operator selected by the selection unit 62 using any one of the first method to the third method described above.

For example, when the determining unit 63 adopts the first method, the effect of not using the information registered by all the operators selected by the selecting unit 62 and the case of using only the information registered by each operator Based on the difference with the effect of, the rate of compensation for each business operator is determined. When the second method is adopted, the determination unit 63 uses the information registered by all the businesses selected by the selection unit 62, and when the information registered by each business is not used. Based on the difference with the effect of, the rate of compensation for each business operator is determined.

Further, when adopting the third method, the determining unit 63 generates a combination of a predetermined business operator and another business operator from the plurality of business operators selected by the selecting unit 62. Further, for each of the generated combinations, the determining unit 63 calculates the difference between the effect when the business operators included in the combination register and the effect when the information registered by the selected business operator is not used. Further, the determination unit 63 calculates the difference between the effect when the information registered by the selected business operator is not used and the effect when only the information registered by the predetermined business operator is used. Then, the determining unit 63 determines the proportion of the reward to the predetermined business operator based on the calculated average value of the differences.

The setting unit 64 sets a reward for each business operator based on the ratio determined by the determination unit 63, with the reward for providing the analysis result satisfying the purpose of use as a source. For example, when the model selected by the effect estimation unit 61 as the model to be processed is provided to the business operator, the setting unit 64 determines a part of the reward provided by the business operator by the determination unit 63. The information used when creating the model to be processed is provided to the registered business operators in proportion. The setting unit 64 may be integrated with the setting unit 54.

Next, an example of the functional configuration of the estimation control unit 70 will be described with reference to FIG. As shown in FIG. 15, the estimation control unit 70 includes a company estimation unit 71, a request unit 72, and a setting unit 73.

The business operator estimation unit 71 estimates a business operator who owns information of a type corresponding to the purpose of use. For example, the business entity estimation unit 71 estimates a business entity that owns information of a type that is useful for prediction. In addition, for example, the business entity estimation unit 71 estimates the type of information that can accurately achieve the purpose of use when combined with the information owned by a predetermined business entity, and estimates the business entity that owns the estimated type of information. To do.

For example, when the purpose of use registration is performed, the business entity estimation unit 71 estimates the type of information required to generate an analysis result that satisfies the purpose of use, based on the content of the purpose of use. The business entity estimation unit 71 may estimate the type of information required to improve the accuracy of the analysis result. Such estimation can be realized by a model that learns the relationship between the accuracy of analysis results created in the past, the type of information used to create the analysis results, and the content of the purpose of use. is there.

Subsequently, the business entity estimation unit 71 refers to the business entity database 31 and identifies the business entity that is estimated to have the information of the estimated type. For example, the business entity estimation unit 71 identifies a business category or business category that is estimated to have the estimated type of information, and identifies a business entity of the identified business category or business category.

The request unit 72 requests the estimated business operator to provide information corresponding to the purpose of use. For example, the request unit 72 is necessary for the business operator estimated by the business operator estimation unit 71 in order to improve the accuracy of the analysis result and the type of information required to generate the analysis result that satisfies the purpose of use. Notify the type of information, and request registration of information of the notified type. Note that the request unit 72 refers to the registration information database 33 and registers the type information necessary to generate an analysis result that satisfies the purpose of use and the type information necessary to improve the accuracy of the analysis result. If so, permission to use such information may be requested. That is, the request unit 72 requests registration of information corresponding to the purpose of use or provision of permission to use the information registered by the business.

When the estimated information provided by the business operator is used for the purpose of use, the setting unit 73 sets a predetermined reward for the business operator. For example, the setting unit 73 uses the information registered by the business operator to obtain the analysis result when the business operator requested to register the information by the requesting unit 72 registers the information, when the business operator permits the use of the information. When created, a predetermined reward is set for the business.

The setting unit 73 may execute the same processing as the setting units 54 and 64, or may be integrated. For example, the setting unit 73 may set the reward for the business according to the degree of contribution of the information provided by the business to the purpose of use. For example, the setting unit 73 sets the reward for the business operator based on the difference between the effect when the provided information that is the estimated information provided by the business operator is used and the effect when the information is not used. Good. Further, the setting unit 73 may set the reward for the business operator based on the correct answer rate of the model generated using the information provided by the business operator. Further, the setting unit 73 may set a reward according to the accuracy of the analysis result for the DS. Further, when the setting unit 73 receives the provision of the actual measurement information corresponding to the analysis result from the analysis result providing destination, the setting unit 73 may set a predetermined reward for the providing destination.

Next, an example of the functional configuration of the provision control unit 80 will be described with reference to FIG. As shown in FIG. 16, the provision control unit 80 has an information provision unit 81 and a setting unit 82. When receiving the information reference request, the information providing unit 81 provides the reference information in a predetermined format. For example, when the information providing unit 81 receives the item name of the information to be referred to, it extracts the value of the type indicated by the item name from the information registered in the registration information database 33, and provides the extracted value.

For example, when the information providing unit 81 receives a value serving as a search query, an item name of a value serving as a search query, and an item name of a value serving as a reference target, the item name of the value serving as a search query indicates Information in which the value of the type matches the value serving as the search query is searched, the value of the type indicated by the item name of the value to be referenced is extracted from the searched information, and the extracted value is provided. In addition, when a plurality of pieces of information in which the value of the type indicated by the item name of the value serving as the search query matches the value serving as the search query is registered, the information providing unit 81 selects among the values included in the plurality of information Alternatively, the value of the type indicated by the item name of the value to be referred to may be extracted, and one value may be provided based on the plurality of extracted values.

For example, the information providing unit 81 uses the key value (that is, the value that becomes the search query), the key item (that is, the item name of the value that becomes the search query), and the acquisition item (that is, the item name of the value that is the reference target). ) And accept. In such a case, the information providing unit 81 refers to the conversion table 36 to identify the item name corresponding to the key item, and among the information registered in the registration information database 33, the value of the identified item name is the key value. Find records that match. The information providing unit 81 uses the conversion table 36 to convert the key value into a value corresponding to the item name for each identified item name, and creates a record having a combination of the item name and the converted key value. You may search.

Then, the information providing unit 81 refers to the conversion table 36, identifies the item name corresponding to the acquired item, and extracts the value of the identified item name from the retrieved records. The information providing unit 81 also uses the conversion table 36 to arrange the extracted values in a predetermined format. For example, the information providing unit 81 converts the value “2” of the item name “sex” into the value “female” of the item name “sex”. Then, the information providing unit 81 provides the issuer of the search query with the value having the largest common value among the values arranged in the predetermined format.

When the format of the information registered in the registration information database 33 is the same as the format of the information provided by the information providing section 81, the setting section 82 sets a predetermined amount of charge to the information providing destination and sets each format. If they are different from each other, a fee larger than a predetermined amount is set for the information providing destination. Further, the setting unit 82 sets a predetermined amount of charge to the business operator when the format of the information received from the business operator and the information provided by the information providing unit 81 are the same, and when the formats are different, Set a higher amount than the prescribed amount for the business operator. For example, the setting unit 82 sets a charge to the business operator according to the degree of agreement between the format of the information received from the business operator and the format of the information provided by the information providing unit 81.

For example, the setting unit 82 calculates the matching degree of the formats based on whether the item names given to the information indicating the same phenomenon match, or whether the values indicating the same phenomenon match. A fee is set for the business operator according to the calculated degree of agreement. The setting unit 82 may execute the same processing as the setting units 54, 64, and 73, or may be integrated.

Returning to FIG. 6, the calculation control unit 90 calculates the reward for each DS according to the order in which each DS provided the analysis result to the user and the accuracy of each analysis result. For example, the calculation control unit 90 calculates the ratio of the predetermined reward allocated to each DS according to the order and accuracy, and calculates the reward for each DS based on the calculated ratio.

For example, the calculation control unit 90 refers to the model database 35 at a predetermined timing, a plurality of models created for the same purpose of use, the date and time when each model was provided, and the DS that created each model. , Specify the accuracy of each model. Subsequently, the calculation control unit 90 identifies the order in which the identified model is provided. In addition, the calculation control unit 90 refers to the usage purpose database 34 and identifies the available data associated with the usage purpose identified from the model database 35.

[4. Modified example)
The information management device 10 described above may be implemented in various different forms other than the above-described embodiment. Therefore, another embodiment of the information management device 10 will be described below.

[4-1. Information management device]
For example, in the information management device 10, the presentation device that executes the presentation process, the selection device that executes the selection process, the estimation device that executes the estimation process, the provision device that executes the provision process, and the calculation device that executes the calculation process cooperate with each other. It may be realized by performing the operation. For example, the control units 50 to 90 shown in FIG. 6 may be installed in independent devices. The databases 31 to 35 and the conversion table 36 registered in the storage unit 30 may be registered in an external storage server.

Further, the information management device 10 may execute all the processes, or may execute only any of the processes described above. Further, the information management device 10 may execute the processes described above in combination. For example, the information management device 10 may consider the result of the calculation process executed by the calculation control unit 90 when the presentation control unit 50 sets the reward.

Further, in the above-described example, the information management device 10 receives the analysis result satisfying the purpose of use accepted from the business operator, but the embodiment is not limited to this. For example, the information management device 10 accepts registration of the purpose of use from various users other than the business operator, accepts the analysis result satisfying the purpose of use from the DS, and provides the analysis result accepted from the DS. It may be provided to users. In addition, the information management device 10 may or may not accept the designation of the information to be used without fail when accepting the registration of the purpose of use.

[4-2. About rewards]
The information management device 10 determines whether or not information of the same type as the information registered by each business operator is registered, the number of times of use when creating an analysis result, ease of use, newness of information, Information registered by each business operator based on various criteria, such as whether the information has the same item name as the registered information or the value of the same item name as the already registered information has the same format. The value may be estimated and a reward according to the estimated value may be provided to the business operator.

[4-3. Regarding requirements for creating analysis results]
Here, the information management device 10 may request the DS to satisfy a predetermined requirement when creating the analysis result. For example, the information management device 10 stores information acquired by the business operator Z that provides the data management service, that is, various web services, as well as information acquired by the business operator Z that provides the data management service and information registered by another business operator. May be requested to be combined to create an analysis result. That is, the information management device 10 may request the DS to use at least logs of various web services acquired by the business operator Z.

[4-4. About information]
Here, the information management device 10 may accept registration of arbitrary information. For example, in the above-mentioned example, the information management device 10 has received the registration of the information of the user who has used the service of each business. However, the embodiment is not limited to this.

Further, in the above-described example, the example in which the identifier for identifying the user is registered in each information has been described, but the embodiment is not limited to this. For example, the information management device 10 combines the information in which the user is associated with the telephone number and the information in which the telephone number and the sales history are associated with each other to associate the user with the sales history and associate them with each other. You may make a sales forecast etc. from a result. That is, each processing described above can be applied regardless of the content of the registered information.

[4-5. Data management service architecture]
Here, in the above-described example, the information management device 10 manages the information registered by each business operator as it is as a data management service. However, the embodiment is not limited to this. The information management device 10 may manage information using an arbitrary architecture.

For example, each business operator may use different platforms (for example, cloud services operated by different business operators). For example, A cloud service (hereinafter referred to as "A cloud"), B cloud service (hereinafter referred to as "B cloud"), C cloud service (hereinafter referred to as "C cloud") and D cloud service (hereinafter referred to as "C cloud") "D cloud") is provided. It should be noted that each cloud service is provided by one or a plurality of servers and is operated by different operators.

Here, the data of the business operator A is registered on the platform in the A cloud (hereinafter referred to as “A platform”), and the data of the business operator B is described in the platform in the B cloud (hereinafter referred to as “B platform”). Data of the business C is registered on the platform in the C cloud (hereinafter referred to as “C platform”), and the data of the business D is registered in the platform of the D cloud (hereinafter referred to as “D platform”). It is registered above.

The information management device 10 may realize a data management system by linking the A platform to the D platform. That is, the information management device 10 manages the data of each business operator A to D using a platform in which the A platform to the D platform are linked (hereinafter, a linked platform). Then, the information management device 10 enables mutual use of data between businesses using different cloud services via the cooperation platform.

For example, each of the businesses A to D may be able to access the data arranged in each cloud from any cloud. For example, each business operator A to D uses the interface API provided by the information management device 10 to transfer data arranged in one cloud (for example, A cloud) from another cloud (for example, B cloud). It may be accessible. Further, the information management device 10 may be able to access each of the platforms included in the cooperation platform.

Further, sharing of data in such a cooperation platform may be performed using metadata. For example, the information management device 10 may share metadata, which is additional data for explaining the data, instead of the data itself registered in each cloud platform. Here, the metadata is, for example, data associated with actual data, but does not include specific customer information or the like, and is information indicating that the data is “customer information”. is there. The metadata includes, for example, the name of the business operator who has registered the metadata (identification information for identifying the business operator), the date and time of registration, information for identifying the substantive data corresponding to the meta data, the category of the substantive data, and the like. May be included. The information management apparatus 10 may share the metadata so that the operator can access the data in the platform PF from any cloud.

Further, the information management device 10 may request the businesses A to C to register the metadata, or may automatically generate the metadata. Further, the information management device 10 may be able to set access authority regarding metadata, which is different for each business operator A to D. That is, the information management apparatus 10 may use the approval system for taking out from the shared space. Further, the information management device 10 may be capable of tracking data such as which business operator has accessed the data registered by which business operator.

For example, the information management device 10 sets a common space, and associates the data input to the shared space with the information indicating the business operator serving as the provider. Then, in order to access the data input to the shared space, the information management device 10 makes an inquiry to all the business operators who are the providers of the data for approval, and when the approval is obtained from all the business operators. Alternatively, data may be provided. In addition, the information management apparatus 10 obtains the consent of all the providers of all the data to be processed in order to bring out the data output as a result of various processes from the data registered by each business such as the analysis result. You may make it necessary. Further, the information management device 10 traces back all the inputs of the further generated data using the analysis result, that is, the data obtained by further processing the processing result, and obtains the consent of all the providers of all the referred information. You may be required to obtain it.

Further, for example, the information management device 10 integrates metadata corresponding to the data owned by each of the businesses, which is registered on the platform where the data is managed and registered by the business operator who owns the data. Integrated metadata may be generated. In other words, the information management device 10 generates information such as a catalog of data held by each business operator that performs data cooperation. Thereby, each business operator can refer to the outline of the data held by the other business operators, so that data sharing (data cooperation) between the plurality of business operators can be smoothly performed.

Further, the information management device 10 may make a proposal regarding the setting of the access authority to the metadata to the business operator who has registered the metadata, based on the usage status of the data corresponding to the metadata. For example, the information management device 10 learns the usage status of the data owned by the business operator A and the data owned by the business operator C, and the data is stored in the business operator C for the business operator A according to the usage status. Public disclosure (setting of access authority) may be proposed. In addition, the information management apparatus 10 may set the content of data or the condition of metadata that must be registered when a new enterprise E newly enters. The information management device 10 can encourage each company participating in the data cooperation to actively disclose and use the data. As a result, the information management device 10 can proceed to utilize useful data owned by each business operator.

In the case of such an architecture, data can be exchanged between companies without necessarily passing through the company Z that provides a data management service, and how the data is used by the company Z You can figure it out.
