FIG. 4 is a diagram illustrating an example of a providing process executed by the information management apparatus according to the embodiment. FIG. 5 is a diagram illustrating an example of a calculation process executed by the information management apparatus 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”). 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 servers 210 to 230 (hereinafter referred to as “business server 200”). And a DS (Data Scientist) terminal 300 via a network N such as the Internet (for example, see FIG. 6). Note that the information management apparatus 10 may be able to communicate with an arbitrary number of web servers 100, provider servers 200, and DS terminals 300.

  The web server 100 is an information processing device that implements 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 web search related services. The web server 120 also provides services related to electronic commerce for various types of transactions, 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 implement any web service. Here, the web server 100 holds a log for providing various web services. Such a log includes, for example, an identifier (for example, a user ID (Identifier)) for identifying a user who has been provided with a service, a user attribute (for example, a demographic attribute or a psychographic attribute), The contents of the provided service (for example, contents of distributed information and purchase history) are included. Note that the format and content of information stored as a log may be different for each service or may be aligned.

  The business server 200 is an information processing device used by each business, and is realized by, for example, a server device or a cloud system. For example, the company server 210 is an information processing apparatus used by a company A that conducts a cosmetic sales business. Further, the company server 220 is an information processing apparatus used by the company B that conducts food manufacturing and sales business. Further, the business server 230 is an information processing apparatus used by a business operator C that conducts a business for selling various products.

  Here, the provider server 200 manages information related to services provided by each provider. Here, the information regarding the service provided by each operator is, for example, information that associates the user who received the service provided by each operator and the content of the service provided to the user, that is, each This is a log of service by a business operator. In addition to such information, the business server 200 can employ any information as long as it is information related to services provided by each business.

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

[1-1-1. Overview of the presentation process provided by the information management device]
Similar to the web server 100, the information management apparatus 10 provides a service (hereinafter sometimes referred to as “data management service”) managed and operated by the operator Z. More specifically, the information management apparatus 10 accepts registration of information held by a plurality of business operators and uses a service that provides various types of information based on the received information, that is, uses information of a plurality of business operators. Provided cloud services.

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

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

  Therefore, the information management apparatus 10 executes the following processing as part of the cloud service. First, the information management apparatus 10 accepts registration of information usage purposes. Here, the purpose of use is the purpose of use of information registered by each business operator, and is information indicating the content of the problem to be solved, the predicted content, the analysis content, and the like. When the registration of the purpose of use is accepted, the information management apparatus 10 presents the purpose of use to a data scientist (hereinafter referred to as “DS”). For example, the information management apparatus 10 presents the purpose of use to DS1 belonging to the operator Z, the event persons A to C who have registered information, and the DS2 that is different from the operator Z that manages 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 uses the 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 content of the purpose of use is a solution to a problem or a prediction, the DS creates a model that solves such a problem or performs a prediction as an analysis result. For example, the DS creates, as an analysis result, a model in which features of information registered by a plurality of business operators are integratedly learned, that is, a model in which learning is performed using information registered by a plurality of business operators. In addition, when the purpose of use is prediction of a predetermined event, the DS creates a model for predicting a predetermined event as an analysis result using information registered by a plurality of operators.

  Then, the information management apparatus 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 apparatus 10 realizes provision of a service that uses information registered by a plurality of operators in an integrated manner while ensuring the confidentiality of information registered by other operators to some extent. In other words, the information management apparatus 10 does not provide each business operator with the information provided by each business operator, but uses the information registered by each business operator in accordance with the purpose of use registered by each business operator. The analysis result created by the DS is provided.

  Here, it is difficult to determine what kind of information is combined and how an analysis result that satisfies the purpose of use can be obtained. For this reason, it may be difficult to create an analysis result that satisfies the purpose of use of each operator by only the DS1 of the operator Z that manages information. Therefore, the information management apparatus 10 presents the purpose of use to the DS 2 different from the business operators A to C and Z. Then, the information management apparatus 10 provides the analysis result created by the DS 2 to the business operator. For this reason, the information management apparatus 10 can promote the use of information registered by a plurality of business operators.

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

  For example, when the information management apparatus 10 receives a usage purpose such as “prediction of a user who purchases a new product” from the business operator B, the information management device 10 provides the usage purpose to the DS 2 and each business operator A to C, Z Of the registered information, the information requested by DS2 is provided to DS2. For example, the information management apparatus 10 performs a “prediction of a user who purchases a new product” by combining a log relating to a web service provided by the operator Z and information relating to cosmetic sales provided by the operator A. When the model is created, the model is provided to the operator B and a predetermined reward is received from the operator B.

  In such a case, the information management apparatus 10 provides a predetermined reward to the DS 2 that created the model, using the reward received from the business operator B as a source. Further, the information management apparatus 10 provides a predetermined reward to the operators A and Z that have registered the information used by the DS 2 using the reward received from the operator B as a source. In addition, the information management apparatus 10 may provide a predetermined operating cost to the business operator Z that operates the above-described outsourcing service, using the reward received from the business operator B as a source.

  In other words, the information management apparatus 10 uses the information registered by each business operator to release a series of flows, such as providing analysis results that satisfy the purpose of use, to the external DS, and from the external DS to algorithms and models. Accept registration of analysis results. And the information management apparatus 10 provides an analysis result with respect to each provider. In other words, the information management apparatus 10 provides an outsourcing service for analyzing information registered by a plurality of business operators. For this reason, the information management apparatus 10 can promote the use of information registered by each business operator.

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

  In addition, the information management apparatus 10 receives, for example, registration of an assignment that is a purpose of use from the business server 230 (step S3). Note that the information management apparatus 10 may accept registration of the purpose of use from the business operator A or business operator B in addition to the business operator C. For example, in the example shown in FIG. 1, the information management apparatus 10 accepts registration of the usage purpose “new cosmetics purchaser prediction” and the reward “reward R1” from the business operator A, and uses the business purpose “product” from the business operator B. Registration of “Sales forecast of A” and reward “reward R2” is received, and registration of the purpose of use “prediction of users interested in product B” from company C and reward “reward R3” is received. In such a case, the information management apparatus 10 presents the purpose of use to DS1, which is a data scientist belonging to the operator Z (step S4), and presents the purpose of use to DS2, which is an external data scientist. (Step S5).

  Here, in the example shown in FIG. 1, although not shown, the information management apparatus 10 specifies the purpose of use in which each DS creates an analysis result from each DS that disclosed the purpose of use, and each DS indicates the analysis result. It accepts the specification of the type of information used when creating. In such a case, the information management apparatus 10 specifies information of a specified type among information registered from each business operator, and inquires of the business operator who registered the specified information whether or not it can be used. . When the use is permitted, the information management apparatus 10 provides the designated type of information to the DS.

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

  Further, the information management apparatus 10 accepts the provision of a model corresponding to the purpose of use designated by DS1 from DS1 (step S6). Further, the information management apparatus 10 accepts the provision of a model corresponding to the purpose of use designated by DS2 from DS2 (step S7). In such a case, the information management apparatus 10 provides a model with a model provided from each DS. For example, when the information management apparatus 10 receives a model that satisfies the usage purpose registered by the operator C from the DS 2, the information management device 10 provides the model to the operator C (step S8).

  In addition, when the information management apparatus 10 creates a model that satisfies the purpose of use registered by the business operator C, the DS 2 uses the information registered by the business operator A and the business operator B. For the use of information (steps S9, S10). Further, the information management apparatus 10 provides a reward for creating a model to the DS 2 (step S11).

[1-1-3. About promotion of entry)
Here, it is considered that a large amount of data is required to predict an event registered as a purpose of use or to improve the accuracy of a model that solves a 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, analysis results that satisfy the purpose of use cannot be created appropriately. There is a fear.

  For example, when the business operator X that performs the delivery business has a list of redelivered addresses, and the business operator Z has a list in which addresses and users are associated with each other, these lists are displayed. When combined, it is possible to identify users with frequent redelivery, and when such users purchase products in the online shopping mall, it is possible to realize efficient delivery such as specifying and sending out a time zone that is easy for users to receive Conceivable. However, if the business operator X does not register the list, there is a possibility that the delivery efficiency cannot be realized.

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

  For example, the information management apparatus 10 requests the business operator A to introduce the same type of business operator. And the information management apparatus 10 sets the reward with respect to the provider A, when registration of information is received from the provider Y of the same industry as the provider A by introduction of the provider A. The reward may be a predetermined amount, or may be set according to the amount or quality of data registered by the operator Y. For example, when the data registered by the operator Y is data that is not similar to the data that has been registered so far, or the data that includes information of a type that has not been registered, The reward for the operator A may be increased. Further, the information management apparatus 10 may calculate the contribution degree of the data registered by the business operator Y by a process similar to the selection process described later, and set an amount of reward according to the calculated contribution degree.

[1-1-4. (About feedback from operators)
Here, in the above-described data management service, if the accuracy of the analysis result provided by the DS is not very good, the frequency of use by each operator may be reduced. Therefore, the information management apparatus 10 may accept feedback from the business operator.

  For example, the information management apparatus 10 provides a model for performing prediction to the business operator A. Then, the information management apparatus 10 requests the provider A to provide feedback. In such a case, the information management apparatus 10 accepts 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 purchase a new product at a predetermined date and time in the future, the information management device 10 receives a new product from the business operator A at a predetermined date and time. The number of users who purchased is received as an actual measurement value (that is, correct answer data).

  Such feedback can be used 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 apparatus 10 may set a predetermined incentive for the business operator who registered the feedback. Further, the information management apparatus 10 may evaluate the DS by using the actual measurement value, or may provide the actual measurement value to the DS and request improvement of the model prediction accuracy.

[1-1-5. About compensation)
Here, the content of the reward in the data management service described above can adopt any mode. For example, the information management apparatus 10 may change the reward for the business operator who has registered the information used to create the analysis result according to the accuracy of the analysis result and the degree of contribution to the accuracy improvement. Further, the information management apparatus 10 may change the reward for the DS depending on the accuracy of the analysis result created by the DS.

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

[1-2-1. About the selection process)
In the data management service described above, when an analysis result is provided to each business operator, a reward is received from the business operator. Such a reward can be used not only as a resource for operating the data management service, but also as a resource for a reward for a business operator who has registered the DS that created the analysis result and the information used to create the analysis result.

  Here, a mode in which a reward corresponding to the degree of contribution of information is provided to each company can be considered. Therefore, the information management apparatus 10 executes the following selection process. First, the information management apparatus 10 accepts the purpose of use of information registered by a plurality of business operators. Moreover, the information management apparatus 10 estimates the effect in a utilization purpose for every combination of information, and selects the information used for a utilization purpose based on the estimated effect. And the information management apparatus 10 determines the ratio of the reward with respect to the some provider who registered information based on the effect in the utilization purpose of the selected information.

  That is, the information management apparatus 10 determines the combination of information that has the maximum 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 degree of contribution to the purpose. And the information management apparatus 10 determines the ratio of the reward with respect to the provider who registered each information according to the calculated contribution.

  For example, the information management apparatus 10 generates a combination of business operators who registered information, and estimates the effect of information registered by the business operators included in the combination for each generated business operator combination. To give a more specific example, the information management apparatus 10 generates all combinations of business operators, and estimates the effect of information registered by the business operators for the generated combinations. Note that the information management apparatus 10 may generate a combination of subsets of information registered by a plurality of business operators, and estimate the effect of information included in the combination for each generated combination of subsets. In addition, the information management apparatus 10 estimates the effect when using the information and the subset registered by the business operators in the order of the number of business operators and subsets, and the improvement rate of the estimated effect sets a predetermined threshold value. If it falls below, the process of estimating the effect may be terminated.

  Here, the effect for each combination of information is, for example, the effect of the information on the analysis result, such as the accuracy of the analysis result when using the information included in the combination (that is, the problem solving accuracy, the prediction accuracy, etc.) Any degree can be adopted as long as the degree is shown.

  For example, when the purpose of use is related to an advertisement, the information management apparatus 10 can employ, as an effect, a CTR (Click Through Rate) improvement rate, a conversion rate, and a profit improvement rate estimated in the future. In addition, when the purpose of use is related to a member business, the information management apparatus 10 can improve the customer acquisition rate, the ARPU (Average Revenue Per User) rate, and the total LTV (Life Time) by improving the customer retention rate. Value) can be used as an effect. In addition, when the purpose of use is related to demand forecasting, the efficiency improvement rate related to logistics, the rate of cost reduction such as labor costs, and the rate of cost reduction associated with preventing loss of sales opportunities can be adopted as effects. . Note that the information management apparatus 10 may use a combination of the various effects described above. That is, the information management apparatus 10 can adopt any degree as an effect as long as it is an effect in accordance with the purpose of use and indicates the effect exerted by each piece of information.

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

  Subsequently, the information management apparatus 10 sets a rate of remuneration for 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 apparatus 10 determines the contribution level of the business operator who has registered each information based on the difference in effect, and sets the rate of reward based on the determined contribution level. In addition, since the information management apparatus 10 sets the ratio of the reward for the business operator who has 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 there is, the reward ratio may be set by any method. In the following description, a first method to a third method for setting a reward ratio will be described as an example.

  For example, the information management apparatus 10 calculates, as the first method, the effect when the information included in the selected combination is not used as the reference effect. And the information management apparatus 10 determines the ratio of the reward with respect to each provider based on the difference between the effect of using only the information registered by each provider and the reference effect.

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

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

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

  Moreover, the information management apparatus 10 calculates the effect at the time of using all the information of the provider X and the operators A to D. Moreover, the information management apparatus 10 is the difference of the effect at the time of not using the information of each provider A-D, and the effect at the time of using all the information of the provider X and the providers A-D. The absolute value is calculated as the contribution of each business operator A to D. And the information management apparatus 10 makes ratio of the calculated contribution degree the ratio of the reward distributed to each provider AD.

  Here, there may be a phenomenon that a great effect is produced when information on a certain business operator is combined with information on a specific business operator. However, in the first method and the second method described above, it is not possible to realize reward distribution in consideration of such an event. Therefore, the information management apparatus 10 may execute the following processing as the third method. For example, the information management apparatus 10 generates a combination of a predetermined business operator and another business operator from a plurality of business operators that have registered the selected information. Further, the information management apparatus 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 apparatus 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 operator is used. And the information management apparatus 10 may determine the ratio of the reward with respect to a predetermined | prescribed provider based on the calculated average value of the difference.

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

  Subsequently, the information management apparatus 10 generates a combination of two operators from the operators A to D. And the information management apparatus 10 calculates the effect at the time of using the information which the provider included in the combination registered for every produced | generated combination, and each calculates the difference of the calculated effect and a reference | standard effect. Then, the information management device 10 divides the sum of the differences calculated for the combination including the operator A by the sum of the differences calculated for all the combinations, and the divided value is divided by the number of combinations including the operator A. Is calculated as the third contribution. That is, the information management apparatus 10 calculates the average value of the contribution degree of the business operator A when the data of the two business operators are used.

And the information management apparatus 10 calculates the average value of the calculated 1st contribution, 2nd contribution, and 3rd contribution, and determines the ratio of the reward with respect to the provider A based on the calculated average value. . That is, the information management apparatus 10 uses the information registered by the operator A and calculates the effect for all 2 ^n-1 cases of using and not using the information registered by the other operators. Based on the calculated average value of the effect, the ratio of the reward for the operator A is set.

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

Here, assuming that the reward associated with the provision of the analysis result is V _all , and the ratio that is allocated to the business that registered the used information in V _all is d, the reward that is distributed to each business by the first method is The remuneration distributed to each operator by the second method can be expressed by the following expression (3). In addition, V '(k) in Formula (3) shows the effect at the time of not using the information of the operator k among the operators included in n.

  Here, the coefficient of contribution by the operator k among the operators included in n can be expressed by the following equation (4). For this reason, the reward distributed with respect to the operator k can be shown by the following formula | equation (5).

[1-2-2. (Example of selection process)
Next, an example of the selection process executed by the information management apparatus 10 will be described with reference to FIG. In addition, in the following description, an example of the process performed when the precision (for example, the prediction precision by a model) which achieves the utilization purpose which the provider X registered as an effect is demonstrated.

  First, the information management apparatus 10 generates a combination of information registered by a plurality of business operators (step S1). And the information management apparatus 10 estimates the precision which achieves a utilization purpose, when it uses for a predetermined utilization purpose for every combination (step S2). Then, the information management apparatus 10 selects a combination of business operators that maximizes accuracy (step S3). In the following description, it is assumed that the information management apparatus 10 has selected a combination including the operators A to D as a combination of operators having the maximum accuracy.

  Subsequently, when determining the rate of remuneration for each business operator A to D using the first method, the information management device 10 estimates the accuracy when using each business operator's data (step S4). . For example, the information management apparatus 10 uses the accuracy “110” when information registered by the business operator X and the business operator A is used, and the accuracy “120” when information registered by the business operator X and the business operator B is used. "Accuracy" 130 "when using information registered by the operator X and the operator C and" 140 "accuracy when using information registered by the operator X and the operator D are calculated.

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

  Here, the total of the respective contributions is “100”. For this reason, the information management apparatus 10 divides the contributions of the operators A to D by the total “100” of the respective contributions, so that the proportion of the reward distributed to the operator A is “10%” and the operator B The proportion of reward to be distributed “20%”, the proportion of reward to be distributed to the operator C “30%”, and the proportion of reward to be allocated to the operator D “40%” are calculated.

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

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

  Here, the total of the contributions is “160”. For this reason, the information management apparatus 10 determines that the ratio “6.25%” obtained by dividing the contribution “10” of the operator A by the total “160” of each contribution is the remuneration ratio distributed to the operator A. To do. Similarly, the information management apparatus 10 provides a rate of reward “18.75%” to be distributed to the operator B, a rate of reward “31.25%” to be allocated to the operator C, and the operator D. The proportion of reward to be distributed “43.75%” is calculated.

  Moreover, when determining the ratio of the reward for each business operator A to D by the third method, the information management apparatus 10 selects the business subject to be processed from among the business operators A to D as the selected business, The difference from the total increase in accuracy is calculated for all combinations of the operator and the other business operators, and the reward ratio is calculated based on the average value of the calculated differences (step S8). For example, the information management apparatus 10 selects the business operator A as the selected business operator. In such a case, the information management device 10 uses the ratio “10%” of the reward for the operator A calculated using the first method as the first contribution, and the reward for the operator B calculated using the second method. The ratio of “6.25%” is the second contribution.

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

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

[1-3-1. Overview of estimation processing provided by information management device]
Here, in the above-described data management service, when 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 apparatus 10 executes the following estimation process. First, the information management apparatus 10 manages information registered by a plurality of business operators. In addition, the information management apparatus 10 receives the purpose of using information from the user. Then, the information management apparatus 10 estimates a business that owns the type of information corresponding to the purpose of use.

  As a result, the information management apparatus 10 can request the estimated provider to provide information corresponding to the purpose of use, and can improve the analysis accuracy that reaches the purpose of use. In addition, the information management apparatus 10 requests not only a business operator who has estimated registration of information corresponding to the purpose of use, but also requests permission to use the registered information, for example. Also good. Further, for example, when the content of the purpose of use is prediction using information, the information management apparatus 10 may estimate a business operator who possesses information of a type useful for the prediction.

  In addition, in the data management service described above, it can be said that the information of the operator Z is in principle usable. Therefore, the information management apparatus 10 may estimate the type of information that can accurately achieve the purpose of use when combined with the information owned by the operator Z, and may estimate the operator who owns the estimated type of information. .

  In addition, the information management apparatus 10 may set a predetermined reward for the provider when the information provided by the estimated provider is provided for the corresponding usage purpose. For example, when the analysis result created using information provided by the operator is a model, the information management device 10 may set a reward for the operator based on the accuracy rate of the created model. .

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

  Here, as in the presentation process described above, the information management apparatus 10 serves as a registration source of the usage purpose based on the analysis result generated by the predetermined DS according to the usage purpose based on information registered by a plurality of business operators. It may be provided to the operator. In such a case, the information management apparatus 10 may set a reward corresponding to the accuracy of the analysis result in the DS. In addition, the information management apparatus 10 may set a predetermined reward for the provider when receiving provision of actual measurement information corresponding to the analysis result from the provider that provides the analysis result.

[1-3-2. An example of the estimation process provided by the information management device)
Hereinafter, an example of the estimation process executed by the information management apparatus 10 will be described with reference to FIG. For example, the information management apparatus 10 receives the purpose of use from the business operator B (step S1). In such a case, the information management apparatus 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 apparatus 10 accepts the purpose of use such as “predicting sales of the product A” from the business operator B. In addition, the information management apparatus 10 accepts designation of data indicated by “DID # 2” as usable data that can be provided by the business operator B for the purpose of use. In such a case, the information management apparatus 10 estimates the type of information necessary for realizing the “prediction of sales of the product A” by combining with “DID # 2”.

  For example, the information management apparatus 10 determines the relationship between the purpose of use registered in the past and the type of information (for example, user attributes and purchase history) used by the DS to satisfy the purpose of use. Generate a learned model. Then, the information management apparatus 10 may estimate the type of information necessary to satisfy the usage purpose using the generated model. Further, the information management apparatus 10 may provide the purpose of use to the DS, and may adopt the type of information registered as information that requires the DS as an estimation result. For example, in the example illustrated in FIG. 3, the information management apparatus 10 is a type of information (hereinafter, referred to as “estimated information type”) necessary for satisfying a purpose of use such as “predicting sales of product A”. “Food purchase history”, “user attribute”, “SNS posting history”, and the like are estimated.

  Subsequently, the information management apparatus 10 identifies information of a type for which information is not registered by the business operator from among the estimated types of information (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 indicate that “SNS posting history” is not registered. Identify.

  Then, the information management apparatus 10 estimates a business operator that holds the specified type of information (step S4). For example, the information management apparatus 10 holds in advance the business types of the operators A to D. And the information management apparatus 10 selects the provider of the industry with high relevance with the specified classification. For example, in the example illustrated in FIG. 3, the information management apparatus 10 selects the business operator D whose business type is “SNS”.

  And the information management apparatus 10 requests | requires registration of information with respect to the selected provider D (step S5). Further, when the information management apparatus 10 accepts registration of information from the business operator D (step S6), the information management device 10 is a model that satisfies the purpose of use generated by the above-described presentation process, and is registered with the business operator D. The model created by using is provided to the operator B (step S7). Thereafter, the information management apparatus 10 provides a predetermined reward for registration of information and use of information to the business operator D (step S8).

[1-4. (Providing processing provided by information management device)
Next, an example of a providing process executed by the information management apparatus 10 will be described with reference to FIG.

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

  For example, the operator A sets an item name such as “sex” in the information indicating the gender of the user, and the operator B sets an item name such as “sex” in the information indicating the user's gender. There may be cases. Further, the business operator B stores character strings such as “male” and “female” as information indicating the sex of the user, and the business operator C has a numerical value “1” indicating the male as information indicating the sex of the user. Or a numerical value “2” indicating a woman may be set. 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 identification is performed, the listability of information by DS and the like is improved, but when the operator wants to reuse information registered by the operator, information in a format different from that at the time of registration is provided. There is a fear.

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

  As a more specific example, the information management apparatus 10 accepts 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 from DS or the like. In such a case, the information management apparatus 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. From this, 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, there may be a case where the contents of information registered by a plurality of business operators 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 a plurality of pieces of information that match the value serving as the search query, the information management apparatus 10 The type value indicated by the item name of the reference target value is extracted, and one value based on the 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. You may count for every value of a reference object, and may provide a value with the largest number counted. For example, when there are five pieces of information whose reference target value is “male” and there is one piece of information whose reference target value is “female”, the information management apparatus 10 sets the value “ “Male” may be provided. Further, the information management apparatus 10 has one information whose reference target value is “male” and the reference target value in other information is “null” (that is, not registered), The value “male” may be output.

[1-4-2. About setting of charges according to the format)
Here, the information management apparatus 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 apparatus 10 determines the usage fee according to the difference between the format of the information registered by each business operator and the format used when the information registered by each business operator is provided to another business operator or DS. You may increase or decrease. For example, if the format of the information received from the provider is the same as the format for providing the information, the information management apparatus 10 sets a predetermined amount of charge for the provider and sets the information received from the provider. If the format is different from the format for providing information, the operator may set a fee that is higher than a predetermined amount.

  In addition, the information management apparatus 10 may set a fee according to the degree of coincidence between the format of the information received from the provider and the format used when providing the information. For example, the information management apparatus 10 calculates the degree of coincidence between the format of the information received from the provider and the format for providing the information, and sets the higher the calculated degree of matching for the provider. You may reduce the fee.

  In addition, in the data management service, the information management apparatus 10 sets a usage fee for a business that refers to information when referring to information registered by another business. In such a usage fee, the information management apparatus 10 may increase the usage fee if the registered information format differs from the format for providing information. For example, if 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 predetermined amount of charge for the information providing destination and manages the format of the information to be provided 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. An example of the providing process provided by the information management device)
Hereinafter, an example of the providing process executed by the information management apparatus 10 will be described with reference to FIG. For example, the information management apparatus 10 accepts registration of information from the business operator A (step S1). Further, the information management apparatus 10 accepts registration of information from the business operator B (step S2). In such a case, the information management apparatus 10 manages the registered information as it is without changing the format of the registered information (step S3).

  For example, in the example shown in FIG. 4, the information management apparatus 10 is given the item name “user ID” for the identifier of the user and the item name “gender” for the information indicating the gender of the user. 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. In addition, the information management apparatus 10 is provided with the item name “user ID” for the identifier of the user, and with the item name “sex” for the information indicating the gender 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 apparatus 10 receives a search query from the business operator A (step S4). In such a case, the information management apparatus 10 identifies an item name corresponding to the type of information indicated by the search query, and extracts information of the identified item name (step S5). For example, it is assumed that the information management apparatus 10 has received a search query Q1 including a key item “user ID”, a key value “user # 1”, and an acquisition item “sex” from the operator A. In such a case, the information management apparatus 10 specifies items to be searched according to a conversion table CT set in advance.

  For example, the information management apparatus 10 refers to the conversion table CT, and specifies an item name given to an item corresponding to the key item “user ID”, that is, the same type of information as the key item. For example, in the example illustrated in FIG. 4, the information management apparatus 10 specifies “user ID” as the item name corresponding to the key item. In addition, the information management apparatus 10 refers to the conversion table CT and identifies an item “sex” corresponding to “gender” as an acquisition item.

  As a result, the information management apparatus 10 searches the search query Q1 for the key item “user ID” or “user ID”, the key value “user # 1”, and the acquisition item “sex” or “sex”. ”And search for information registered with each business operator. That is, the information management apparatus 10 searches for information that matches the intention of the search query Q1 from a plurality of pieces of information having different formats by using the conversion table CT.

  For example, in the example illustrated in FIG. 4, the information management apparatus 10 specifies a record whose item name “user ID” is “user # 1” from the information DA, and among the specified records, the item name is The value “null” that is “sex” is specified. Further, the information management apparatus 10 identifies a record whose item name “user ID” is “user # 1” from the information DB, and among the identified records, the value “2” whose item name is “sex”. Is specified. As a result, the information management apparatus 10 selects the value “2” as information to be provided for the search query Q1.

  Further, the information management apparatus 10 specifies the intention of the value “2” whose item name is “sex” in the information DB. For example, the information DB is registered together with the registration that the value “2” of the item name “sex” is “female” and the value “1” of the item name “sex” indicates “male”. Can be realized by creating a conversion table in which the value “1” and “male, value“ 2 ”and“ female ”of the item name“ sex ”are associated with each other. Then, the information management apparatus 10 generates a character string “female” indicating the intention of the selected value “2”, and provides the generated character string “female” to the operator A as a search result (step S6). . For example, the information management apparatus 10 provides the operator A with the key value “user # 1” and the character string “female”.

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

[1-5-1. Overview of calculation processing provided by information management device]
For example, in the data management system described above, 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 a reward for the DS. For example, when rewards are set according to analysis accuracy, many rewards are set for a DS that has the highest analysis accuracy but takes the most time to provide the analysis result.

  Therefore, the information management apparatus 10 executes the following calculation process. First, when the information management apparatus 10 receives the purpose of use of information registered by a plurality of business operators, the information management apparatus 10 presents the purpose of use to a plurality of DSs that analyze information according to the purpose of use. And the information management apparatus 10 calculates the reward with respect to each DS according to the order which DS provided the analysis result, and the precision of each analysis result. For example, the information management device 10 calculates a ratio assigned to each DS out of a predetermined reward according to the order in which each DS provided the analysis result and the accuracy of the analysis result, and based on the calculated ratio To calculate a reward for each DS.

  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 apparatus 10 sets the accuracy of the model when the model satisfying the use purpose is created using only the information held by the business operator who has registered the use purpose as the reference accuracy. Subsequently, when the accuracy of the initially provided model exceeds the reference accuracy, the information management apparatus 10 uses the difference between the reference accuracy and the accuracy of the model as the contribution of the DS that provided the model. .

  For example, the information management apparatus 10 compares the accuracy of the analysis result by the DS with the accuracy of the analysis result provided before the analysis result by the DS as a reward for the DS that provided the analysis result for the second and subsequent times. Calculate a reward based on. For example, if the accuracy of the analysis result by the DS that provided the analysis results for the second and subsequent times is worse than the accuracy of all the analysis results previously provided, the information management apparatus 10 sets the reward for the DS to 0. To do. In addition, the information management apparatus 10 determines that the accuracy of the analysis results obtained by the DS that provided the analysis results for the second and subsequent times is better than the accuracy of all the analysis results previously provided. The analysis result with the highest accuracy is identified from among the analysis results, and a reward is calculated based on the difference between the accuracy of the identified analysis result and the accuracy of the analysis result by the DS.

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

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

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

  Next, the information management apparatus 10 specifies the order in which the models are provided. For example, when the models are provided in the order of DS4, DS1, DS2, and DS3, the information management apparatus 10 provides the order “second” in which DS1 provides the model “the third” in which DS2 provides the model, The order “fourth” in which DS3 provided the model and the order “first” in which DS4 provided the model are specified.

  And the information management apparatus 10 calculates the ratio of the reward provided to each DS based on the contribution according to the precision of each model, and the provided order (step S8). For example, it is assumed that the information management apparatus 10 calculates the reference accuracy and calculates the accuracy “100”. In such a case, the information management apparatus 10 sets the value “5” obtained by subtracting the reference accuracy “100” from the accuracy “105” of the DS4 model provided first as the DS4 contribution. In other words, the information management apparatus 10 sets a contribution degree based on the accuracy increase rate according to the DS4 model to the DS4. For example, when the accuracy of the DS4 model is lower than the reference accuracy, the contribution to the DS4 may be set to “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 reference accuracy of the DS4 model provided earlier. Therefore, the information management apparatus 10 sets a value “3” obtained by subtracting the accuracy “105” of the DS4 model provided earlier 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 third DS2 model provided with the accuracy “108” of the DS1 model having the highest accuracy among the previously provided models. . Here, the accuracy “103” of the DS2 model provided third is lower than the accuracy “108” of the DS1 model. Therefore, the information management apparatus 10 sets the contribution degree of DS2 to “0”.

  Subsequently, the information management apparatus 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 previously provided models. . Here, the accuracy “110” of the DS3 model provided fourth is higher than the accuracy “108” of the DS1 model. Therefore, the information management apparatus 10 sets a 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.

  And the information management apparatus 10 makes ratio of contribution of each DS1-DS4 the ratio of the reward provided to each DS1-DS4. For example, the information management apparatus 10 extracts a part of the reward received in step S5 as the total amount of reward provided to each DS1 to DS4. Then, the information management apparatus 10 distributes 50% to DS4, 30% to DS1, and 20% to DS3 in the total amount of rewards extracted.

  In the above-described 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 that created the model, and further, the additional reward distributed by the calculation process described above May be set.

[2. Configuration of information management device]
Hereinafter, an example of the functional configuration of the information management apparatus 10 described above will be described. FIG. 6 is a diagram illustrating a configuration example of the information management apparatus according to the embodiment. As illustrated in FIG. 6, the information management apparatus 10 includes a communication unit 20, a storage unit 30, and a control unit 40.

In addition, the storage unit 30 includes a provider database 31, a DS database 32, a registration information database 33, a usage purpose database 34, a model database 35, and a conversion table 36 (hereinafter may be collectively referred to as “each database 31 to 36”). Remember. Hereinafter, an example of information registered in each of the databases 31 to 36 will be described with reference to FIGS.

  Various types of information related to businesses are registered in the business enterprise database 31. For example, FIG. 7 is a diagram illustrating an example of a business entity database according to the embodiment. In the example shown in FIG. 7, the “entrepreneur ID”, “business category”, “business category”, “registration information”, and the like are registered in association with the business operator database 31. In addition, in the provider database 31, other information related to the provider may be registered in addition to the information illustrated in FIG.

  Here, the “operator ID” is an identifier for identifying a business operator. The “business type” is information indicating the type of product or service provided by the business, that is, the business type of the business. The “business type” is information indicating a business type such as whether a business provides a product or service by mail order or a store. The “registration information” is information indicating whether the business operator has registered information in the data management service.

  For example, in the example illustrated in FIG. 7, the business entity database 31 stores business ID “business A”, business type “cosmetics”, business format “mail order”, and registration information “present” in association with each other. Such information is a business type in which the business type of the business indicated by the business ID “Business A” sells “cosmetics”, and is a business format in which “cosmetics” is sold by “mail order”. Is registered.

  Information about DS is registered in the DS database 32. For example, FIG. 8 is a diagram illustrating an example of the DS database according to the embodiment. In the example shown in FIG. 8, the DS database 32 registers “DSID”, “DS information”, “affiliation”, “providing history”, and the like in association with each other. In the DS database 32, any information related to the DS may be registered in addition to the information shown in FIG.

  Here, “DSID” is an identifier for identifying a DS. The “DS information” is various information related to the DS such as the name, age, and career of the DS. Further, “affiliation” is information indicating the affiliation of the DS, for example, information indicating whether the DS belongs to the operator Z that operates the data management service. The “provided history” is information indicating a 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. A character string indicating DS information, an analysis result created and provided by the DS, and the like are registered.

  For example, in the example illustrated in FIG. 8, information such as DSID “DS # 1”, DS information “DS information # 1”, affiliation “internal”, and provision history “model # 1” is registered in the DS database 32 in association with each other. Has been. As such information, the DS information indicated by the DSID “DS # 1” is “DS information # 1”, belongs to the operator Z, and has created and provided a model indicated by “model # 1” in the past. Indicate.

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

  For example, the “business operator ID” is an identifier indicating a business operator who has registered information. The “data ID” is an identifier for identifying information registered by the business operator. For example, when a certain business operator registers the first information and then registers the second information, an individual data ID is assigned to each of the first information and the second information. The “subset ID” is an identifier indicating a subset to which the data belongs, and is information that can be arbitrarily set by the operator. The company ID, data ID, and subset ID are information that is automatically given when the company registers data. Information registered by the company, that is, information acquired by the company, 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 the user who has received the service of the business indicated by the business ID. “Gender” is the gender of the user indicated by the associated “user ID”, and “purchasing history” is information indicating the purchasing history of the user.

  Here, in the example illustrated in FIG. 9, the registration information database 33 includes an operator ID “operator A”, a data ID “DID # 1”, a subset ID “subset # 1”, and a user ID “user # 1”. , Information such as gender “null” and purchase history “purchase history # 1” are registered in association with each other. Such information is information registered by the provider indicated by the provider ID “provider 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, the record has items such as “user ID”, “sex”, 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 a usage purpose database according to the embodiment. In the example illustrated in FIG. 10, the usage purpose database 34 registers information such as “use purpose ID”, “use purpose (issue)”, “use company”, “available data”, and “reward” in association with each other. Has been. In the usage purpose database 34, any information related to the usage purpose may be registered in addition to the information shown in FIG.

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

  For example, in the example illustrated in FIG. 10, the usage purpose database 34 includes a usage purpose ID “U # 1”, a usage purpose (issue) “prediction of a purchaser of new cosmetics”, a usage operator “business operator A”, Information such as data “DID # 1” and reward “reward R1” is registered in association with each other. Such information is data that can be provided by “business operator A” because “predictor of new cosmetic purchaser” is registered by “business operator A” as the usage 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 that satisfies the purpose of use is the reward “reward R1”. In the example shown in FIG. 10, conceptual values such as “U # 1” and “reward R1” are described. However, in reality, there are numerical values for identifying the purpose of use, character strings, numerical values indicating the amount of reward, and the like. be registered.

  In the model database 35, models as analysis results are registered. For example, FIG. 11 is a diagram illustrating an example of a model database according to the embodiment. In the example shown in FIG. 11, “model ID”, “DSID”, “use purpose ID”, “provided date”, “accuracy”, “use information”, and the like are registered in the model database 35 in association with each other. . In addition to the information shown in FIG. 11, arbitrary information related to the model created as an analysis result may be registered in the model database 35.

Here, the “model ID” is an identifier for identifying a model. “DSID” is a DSID that identifies the DS that created and provided the model. In addition, “use purpose ID
Is a use purpose ID indicating a use purpose that the model satisfies. The “provided date and time” is information indicating the date and time when the model was provided from the DS. “Accuracy” is information indicating the accuracy of the model. “Usage information” is a data ID of information used to create a model. In the example shown in FIG. 11, a conceptual value such as “provided date / time ID” is described. However, a character string indicating the provided date / time is actually registered.

  For example, in the example illustrated in FIG. 11, the model database 35 includes a model ID “model # 1”, a DSID “DS # 1”, a usage purpose ID “U # 1”, a provision date and time “provision date and time # 1”, and an accuracy “ 105 ”and usage information“ DID # 1, DID # 2,... ”Are registered in association with each other. 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”. Further, such information is provided on the date and time indicated by the provided date and time “provided date and time # 1”, the accuracy value for the purpose of use is “105”, and the usage information “DID # 1, DID # 2. “Indicates that the model is created using the information indicated by“ ”.

  The conversion table 36 is a table showing item name and value conversion rules. For example, FIG. 12 is a diagram illustrating an example of the conversion table according to the embodiment. In the example illustrated in FIG. 12, information such as “item”, “corresponding item”, and “conversion rule” is registered in the conversion table 36 in association with each other. In addition to the information shown in FIG. 12, various conversion rules employed 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 for performing value conversion. In the example shown in FIG. 12, a conceptual value such as “conversion rule # 1” is described, but actually, a character string, a conditional expression, and the like indicating how the value is converted are registered.

  For example, in the example illustrated in FIG. 12, the conversion table 36 includes a combination of the corresponding item “sex” and the conversion rule “conversion rule # 3 (1: male, 2: female)” for the item “sex”, and A set 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 is selected from among the information registered by each business operator from the values whose item name is “sex”, “sex”, or “sex information”. Indicates that a value corresponding to the key value is searched. Further, such information indicates that when a value whose item name is “sex” is referred to, a value corresponding to the key value is searched according to “conversion rule # 3”. For example, in such information, the value “1” with the item name “sex” is equivalent to the value “male” with the item name “sex”, and the item name “sex” is given. The value “2” indicates that it 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 apparatus 10 by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. Is realized 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 is a generic name of the presentation control unit 50, the selection control unit 60, the estimation control unit 70, the provision control unit 80, and the calculation control unit 90 (hereinafter, “each control unit 50 to 90”). May have.) Here, the presentation control part 50 implement | achieves the presentation process mentioned above. In addition, the selection control unit 60 implements the selection process described above. In addition, the estimation control unit 70 realizes the above-described estimation process. Also, the provision control unit 80 realizes the provision process described above. In addition, the calculation control unit 90 realizes the calculation process described above.

  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 a 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 an 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 a functional configuration of the presentation control unit 50 will be described with reference to FIG. As illustrated 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 business operators. More specifically, the management unit 51 manages information registered by a plurality of business operators and having individual formats, while maintaining the formats. For example, when the management unit 51 receives information to be registered from the business operator, the management unit 51 assigns the business operator ID and the data ID, and does not change the format, that is, without converting the item name or value. The information is registered in the registration information database 33 as it is.

  Here, each company 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 including a plurality of values in which item names indicating types are set, and a plurality of types of information in which different item names are set for the same type value. It will be. In addition, when the management unit 51 receives a reference request for information registered by the operator, the management unit 51 provides the information to the operator.

  In addition, the management unit 51 provides information registered by the operator to the DS. For example, when the management unit 51 receives a request for providing information from the DS 2, the management unit 51 identifies the business operator who registered the information to be provided from the registration information database 33, and determines whether the information can be provided to the identified business operator. Inquire. At this time, the management unit 51 may notify the contents of the purpose of use, information on the business operator who registered the purpose of use, information on the DS, and the like. Then, the management unit 51 provides only the information obtained by the registered operator among the information to be provided to the DS.

  The accepting unit 52 accepts the purpose of use of information registered by a plurality of businesses from an arbitrary user. For example, when the receiving unit 52 receives the contents of the purpose of use, the specification of the usable data, the contents of the reward, etc. from the business operator, the received purpose of use, the DID indicating the usable data, and the reward are used for the purpose-of-use database 34. Register with. For example, the accepting unit 52 accepts registration of a predetermined event to be predicted as the content of prediction using information. In such a case, the information management apparatus 10 requests each DS to create a model for predicting a predetermined event.

  When receiving the purpose of use of information registered by a plurality of business operators, the presenting unit 53 presents the purpose of use to a plurality of DSs that analyze information according to the purpose of use. For example, the presentation unit 53 presents the purpose of use registered in the purpose of use database 34 in response to a presentation request from each DS. Here, the presentation unit 53 presents the purpose of use to a DS that is different from an event person who has registered information and an operator who manages information registered by a plurality of companies. That is, the presentation unit 53 presents the purpose of use not only to the DS1 belonging to the operator Z but also to the external DS2, and requests 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. Moreover, the setting part 54 sets the predetermined | prescribed reward with respect to the provider who registered the information utilized for preparation of an analysis result, when the analysis result is provided.

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

  Moreover, the setting part 54 may set the predetermined | prescribed reward with respect to a predetermined | prescribed provider, when another provider registers information by introduction of a predetermined | prescribed provider. That is, the setting unit 54 may set a predetermined reward when a business operator who has registered information in the data management service solicits other business operators and the other business operators have registered information. For example, the setting unit 54 may set a predetermined reward for a predetermined business when the business similar to the predetermined business has registered information as another business.

  In addition, for example, the setting unit 54 solicits the business operator estimated by the estimation process executed by the estimation control unit 70 by the business operator who registered information in the data management service, and the estimated business operator registers the information. If so, the amount of remuneration for the business operator who has registered information in the data management service may be increased. That is, when new information required for creating the analysis result is registered, the setting unit 54 may increase the remuneration amount for the business operator who has registered the information.

  The analysis result providing unit 55 provides the business operator with the analysis result generated by the predetermined DS along the purpose of use based on information registered by a plurality of business operators. For example, the analysis result providing unit 55 selects a model that satisfies the purpose of use registered by the operator A, that is, a model that learns using information registered by a plurality of operators, or a model that predicts a predetermined business. When the DS2 creates, the model created by the DS2 is provided to the operator A. Further, the analysis result providing unit 55 registers the model information created by DS2, the date and time of provision, information used for creating the model, and the like in the model database 35 in association with the DSID of 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 part 61 estimates the effect in a utilization purpose for every combination of information. For example, the effect estimation unit 61 generates a combination of business operators who registered information, and estimates the effect of information registered by the business operators included in the combination for each generated business operator combination. For example, the effect estimation unit 61 estimates the effect of information registered by the business operators included in the combinations for all combinations of business operators. Note that the effect estimation unit 61 may generate a combination of subsets of information registered by a plurality of operators, 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 selects the business operator who 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 operator, and estimates the precision at the time of producing | generating a model using the information which the business operator registered for every produced business operator combination.

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

  The determination unit 63 determines the rate 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 a reward for the business operator selected by the selection unit 62 using any one of the first to third methods described above.

  For example, when adopting the first method, the determination unit 63 uses the effect of not using the information registered by all the businesses selected by the selection unit 62 and only the information registered by each business operator. Based on the difference with the effect of the, determine the percentage of compensation for each business. In addition, when adopting the second method, the determination unit 63 uses the information registered by all businesses selected by the selection unit 62 and the case where the information registered by each business is not used. Based on the difference with the effect of the, determine the percentage of compensation for each business.

  Further, when adopting the third method, the determination unit 63 generates a combination of a predetermined business operator and another business operator from the plurality of business operators selected by the selection unit 62. For each of the generated combinations, the determination unit 63 calculates the difference between the effect when the business operator included in the combination registers and the effect when the information registered by the selected business operator is not used. Further, the determination unit 63 calculates a difference between an effect when the information registered by the selected business operator is not used and an effect when only the information registered by the predetermined business operator is used. And the determination part 63 determines the ratio of the reward with respect to a predetermined | prescribed provider based on the calculated average value of the difference.

  The setting unit 64 sets a reward for each business operator based on the ratio determined by the determination unit 63 using the reward for providing the analysis result that satisfies the purpose of use as a resource. For example, when the model selected as the model to be processed by the effect estimation unit 61 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. Providing the information used when creating the model to be processed to the registered operator as a percentage. The setting unit 64 may be integrated with the setting unit 54.

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

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

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

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

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

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

  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 a reward for the business according to the degree of contribution to the purpose of use of the information provided by the business. For example, the setting unit 73 may set a reward for the operator based on the difference between the effect when using the provided information that is information provided by the estimated operator and the effect when not using the provided information. Good. Moreover, the setting part 73 may set the reward with respect to a provider based on the correct answer rate of the model produced | generated using the information which the provider provided. Moreover, the setting part 73 may set the reward according to the precision of the analysis result with respect to DS. Moreover, the setting part 73 may set a predetermined reward with respect to a provision destination, when provision of the measurement information corresponding to an analysis result is received from the provision destination of an analysis result.

  Next, an example of the functional configuration of the provision control unit 80 will be described with reference to FIG. As illustrated in FIG. 16, the provision control unit 80 includes an information provision unit 81 and a setting unit 82. When the information providing unit 81 receives an information reference request, the information providing unit 81 provides information to be referred to in a predetermined format. For example, when receiving the item name of the information to be referred to, the information providing unit 81 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 The information whose type value matches the value serving as the search query is searched, the type value indicated by the item name of the value to be referenced is extracted from the searched information, and the extracted value is provided. Note that the information providing unit 81, 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 are registered, The type value indicated by the item name of the value to be referred to may be extracted, and one value based on the plurality of extracted values may be provided.

  For example, the information providing unit 81 includes a key value (that is, a value that becomes a search query), a key item (that is, an item name of a value that becomes a search query), and an acquisition item (that is, an item name of a value that becomes a reference target) ). In such a case, the information providing unit 81 refers to the conversion table 36, identifies 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 converts the key value into a value corresponding to the item name for each identified item name using the conversion table 36, and records 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 uses the conversion table 36 to align 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 search query issuer with the most common value among the values arranged in a 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 unit 81, the setting unit 82 sets a predetermined amount of charge for the information providing destination, If they are different from each other, a fee larger than a predetermined amount is set in the information providing destination. In addition, the setting unit 82 sets a predetermined amount of charge for the provider when the format of the information received from the provider and the information provided by the information providing unit 81 are the same. Set a fee that is higher than the predetermined amount for the operator. For example, the setting unit 82 sets a fee according to the degree of coincidence between the format of the information received from the provider and the format of the information provided by the information providing unit 81.

  For example, the setting unit 82 calculates the degree of coincidence of the format based on whether the item names given to the information indicating the same event match, or whether the values indicating the same event match, A fee corresponding to the calculated degree of coincidence is set for the operator. 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 a reward for each DS according to the order in which each DS provided the analysis results to the user and the accuracy of each analysis result. For example, the calculation control unit 90 calculates a ratio assigned to each DS in a predetermined reward according to the order and accuracy, and calculates a 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, and 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 Identify the accuracy of each model. Subsequently, the calculation control unit 90 identifies the order in which the identified models are provided. In addition, the calculation control unit 90 refers to the use purpose database 34 and specifies usable data associated with the use purpose specified from the model database 35. And the calculation control part 90 estimates the precision at the time of creating the model which satisfy | fills a utilization purpose using the specified usable data as reference | standard precision.

  Subsequently, the calculation control unit 90 calculates a reward based on the difference between the accuracy of the analysis result by the DS and the reference accuracy as the reward for the DS that first provided the analysis result.

[4. (Modification)
The information management apparatus 10 described above may be implemented in various different forms other than the above embodiment. Therefore, in the following, another embodiment of the information management apparatus 10 will be described.

[4-1. Information management device)
For example, in the information management device 10, a presentation device that executes a presentation process, a selection device that executes a selection process, an estimation device that executes an estimation process, a provision device that executes a provision process, and a calculation apparatus that executes a calculation process are coordinated. It may be realized by operating as described above. For example, the control units 50 to 90 illustrated 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 apparatus 10 may execute all the processes, or may execute only an arbitrary process among the processes described above. Further, the information management apparatus 10 may execute a combination of the above-described processes. For example, the information management apparatus 10 may consider the result of the calculation process executed by the calculation control unit 90 when the presentation control unit 50 sets a reward.

  Moreover, in the example mentioned above, although the information management apparatus 10 was provided with the analysis result which satisfy | fills the utilization purpose received from the provider, embodiment is not limited to this. For example, the information management apparatus 10 accepts registration of the purpose of use from any user other than the business operator, accepts the analysis result that satisfies the purpose of use from the DS, and provides the analysis result accepted from the DS. It may be provided to the user. In addition, the information management apparatus 10 may or may not accept designation of information to be used when accepting registration of the purpose of use.

[4-2. About compensation)
The information management apparatus 10 determines whether 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 that each business operator registers based on various criteria, such as whether the information has the same item name as the registered information, or whether the value of the same item name is the same format as the already registered information The value may be estimated and a reward corresponding to the estimated value may be provided to the operator.

[4-3. (Requirements for creating analysis results)
Here, the information management apparatus 10 may request the DS to satisfy predetermined requirements when creating the analysis result. For example, the information management device 10 includes the information acquired by the operator Z that provides the data management service, that is, the operator Z that provides the data management service together with various web services, and the information registered by other operators. You may request to create an analysis result by combining. That is, the information management apparatus 10 may request the DS to use at least the logs of various web services acquired by the operator Z.

[4-4. Information)
Here, the information management apparatus 10 may accept registration of arbitrary information. For example, in the above-described example, the information management apparatus 10 accepts registration of user information using the service of each business operator. However, the embodiment is not limited to this. For example, the information management apparatus 10 may accept registration of information that does not include information indicating a user, such as a sales history in each region.

  Moreover, although the example mentioned above demonstrated the example in which the identifier for identifying a user was registered into each information, embodiment is not limited to this. For example, the information management apparatus 10 associates and associates a user and a sales history by combining information that associates a user with a telephone number and information that associates a telephone number with a sales history. Sales prediction or the like may be performed from the result. That is, each process described above can be applied regardless of the contents of the registered information.

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

  For example, each provider may use a different platform (for example, a cloud service operated by a different provider). 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. Each cloud service is provided by one or a plurality of servers, and is operated by different operators.

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

  The information management apparatus 10 may realize a data management system by linking such A platform to D platform. That is, the information management apparatus 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, linked platform). And the information management apparatus 10 enables the mutual use of the data between the providers who use different cloud services via the cooperation platform.

  For example, each business operator A to D may be able to access 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 apparatus 10 to transfer data arranged in one cloud (for example, A cloud) from another cloud (for example, B cloud). It may be accessible. The information management apparatus 10 may be accessible to each platform included in the cooperation platform.

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

  Further, the information management apparatus 10 may request each business operator A to C to register metadata, or may automatically generate metadata. Further, the information management apparatus 10 may be an access authority related to metadata, and may be able to set a different access authority for each business operator A to D. In other words, the information management apparatus 10 may make the take-out from the shared space an approval system. In addition, the information management apparatus 10 may be configured to track data such as which company has accessed data registered by which company.

  For example, the information management apparatus 10 sets a common space and associates information indicating a provider serving as a provider with data input to the shared space. And in order to access the data input to the shared space, the information management device 10 inquires for approval from all business operators who are providers of such data, and obtains approval from all business operators Alternatively, data may be provided. In addition, the information management apparatus 10 obtains the consent of all the providers of all data to be processed in order to take out the data output as a result of various processes from the data registered by each business operator, such as analysis results. It may be necessary. In addition, the information management apparatus 10 traces back all the inputs for the further generated data using the analysis result, that is, the data further processed for the processing result, and consents to all the providers for all the referenced information. You may have to get it.

  In addition, for example, the information management apparatus 10 integrates metadata registered from the business owner who owns the data on the platform on which the data is managed, corresponding to the data owned by each business operator. Integrated metadata may be generated. In other words, the information management apparatus 10 generates information such as a catalog of data held by each business operator that performs data linkage. Thereby, since each business operator can refer to the outline of data held by other business operators, data sharing (data collaboration) among a plurality of business operators can be performed smoothly.

  Further, the information management apparatus 10 may make a proposal regarding setting of the access authority for 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 held by the business operator A and the data held by the business operator C, and sends data to the business operator C according to the usage status. May be proposed (access authority setting). Moreover, the information management apparatus 10 may set the content of the data which should be registered, and the conditions of metadata, when the new provider E newly enters. The information management apparatus 10 can encourage each company that participates in data linkage to actively disclose and use data. As a result, the information management apparatus 10 can proceed with the utilization of useful data owned by each business operator.

  In the case of such an architecture, it is possible to exchange data between operators without necessarily going through the operator Z that provides the data management service, and how the operator Z uses the data. I can grasp it.
