DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] [Outline of Information Processing System S] 1 is a schematic diagram of an information processing system S according to this embodiment. The information processing system S includes an information processing device 1, an information terminal 2, and a sales point server 3. The information processing system S may also include other devices such as servers and terminals.

[0022] The information processing device 1 is a computer that processes information related to content. The content is, for example, digital data such as images and music. The content is associated with, for example, a token managed on a blockchain. The token is information indicating the ownership of the content held by any user on the blockchain. The token is, for example, an NFT (Non-Fungible Token) that can be bought and sold between users.

[0023] The token is stored in association with holder identification information (holder ID: Identifier) ​​for identifying the holder, for example, by a blockchain constructed in the storage unit of the information processing device 1 or in the storage unit of a device different from the information processing device 1. The blockchain includes multiple blocks of data, and each block includes one or more transactions indicating that the token has been transferred (that the holder of the token has been changed). Each block in the blockchain includes a hash value generated according to a predetermined rule, and the accuracy of the entire blockchain is guaranteed by checking the consistency of the hash values ​​between blocks.

[0024] The information terminal 2 is a computer used by a user. A user is, for example, a person who participates (belongs to, registers, etc.) in a specific community. A community is a group made up of multiple users. A community sells tokens associated with content such as images and music. The information terminal 2 is, for example, a smartphone, a tablet terminal, or a personal computer. The information terminal 2 has an operation unit such as a touch panel or a keyboard for accepting operations, and a display unit such as a liquid crystal display for displaying information. The information terminal 2 is capable of communicating with the information processing device 1 and the sales outlet server 3 via a network.

[0025] The sales office server 3 is a computer that performs processing for buying and selling tokens on the blockchain. The sales office server 3 allows purchasers to purchase tokens being sold by communities. When a token is bought or sold, the sales office server 3 also transfers assets (cryptocurrency or legal tender) corresponding to the price of the token from the purchaser who purchased the token to the community that sold the token. The sales office server 3 is managed by, for example, a business operator that provides a sales office (platform) for buying and selling tokens or a designated sales manager of a store that opens a store on the platform. The sales office server 3 is capable of communicating with the information processing device 1 and the information terminal 2 via a network.

[0026] An overview of the process executed by the information processing system S according to this embodiment will be described below. The information processing device 1 acquires community information indicating characteristics of the community. The characteristics of the community are identified based on, for example, the content of each of the comments of multiple users, the tokens that each of the multiple users holds on the blockchain, etc.

[0027] The information processing device 1 acquires changed content generated by changing the content based on the community information. For example, the information processing device 1 inputs the content into a predetermined machine learning model stored in advance in the information processing device 1 or another device, and acquires, as the changed content, digital data output by the machine learning model.

[0028] The information processing device 1 outputs the changed content in association with the community. The information processing device 1 outputs information for selling a token associated with the changed content. The sales server 3 sells the token associated with the changed content in accordance with the information output by the information processing device 1.

[0029] In this way, the information processing system S modifies the original content based on the community information indicating the characteristics of the community, and outputs the modified content in association with the community. This enables the information processing system S to generate content that reflects the overall tendency of the community in which multiple users participate.

[0030] [Configuration of Information Processing System S] FIG. 2 is a block diagram of an information processing system S according to this embodiment. In FIG. 2, arrows indicate main data flows, and data flows other than those shown in FIG. 2 may exist. In FIG. 2, each block indicates a configuration in functional units, not a configuration in hardware (device) units. Therefore, the blocks shown in FIG. 2 may be implemented in a single device, or may be implemented separately in multiple devices. Data may be exchanged between blocks via any means, such as a data bus, a network, or a portable storage medium.

[0031] The information processing device 1 includes a communication unit 11, a storage unit 12, and a control unit 13. The information processing device 1 may be configured by connecting two or more physically separate devices by wire or wirelessly. The information processing device 1 may also be configured by a cloud that is a collection of computer resources.

[0032] The communication unit 11 has a communication controller for transmitting and receiving data between the information terminal 2 and the sales server 3 via the network. The communication unit 11 notifies the control unit 13 of data received from the information terminal 2 and the sales server 3 via the network. The communication unit 11 also transmits data output from the control unit 13 to the information terminal 2 and the sales server 3 via the network.

[0033] The storage unit 12 is a storage medium including a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk drive, etc. The storage unit 12 stores in advance a program to be executed by the control unit 13. The storage unit 12 may be provided outside the information processing device 1, in which case data may be exchanged between the storage unit 12 and the control unit 13 via a network.

[0034] The control unit 13 has a community information acquisition unit 131, a content acquisition unit 132, a generation unit 133, an output unit 134, a reception unit 135, and a sales status acquisition unit 136. The control unit 13 is a processor such as a CPU (Central Processing Unit), and functions as the community information acquisition unit 131, the content acquisition unit 132, the generation unit 133, the output unit 134, the reception unit 135, and the sales status acquisition unit 136 by executing a program stored in the storage unit 12.

[0035] Hereinafter, a detailed description will be given of the processing executed by the information processing system S. First, a description will be given of the processing in which the information processing device 1 acquires community information indicating characteristics of a community. Figures 3(a) and 3(b) are schematic diagrams for explaining the processing in which the information processing device 1 acquires community information.

[0036] The community information acquisition unit 131 acquires community information indicating characteristics of the community in response to any one of the multiple users participating in the community performing a predetermined start operation (selection of a start button, etc.) on the information terminal 2. The characteristics of the community are characteristics that may affect the tendency of the community as a whole. The characteristics of the community include, for example, at least one of the internal characteristics (preferences, ideas, etc.) of the multiple users and the external characteristics (place of residence, career, etc.) of the multiple users.

[0037] 3(a), the community information acquisition unit 131, for example, identifies the content of each of the multiple users' comments as the characteristics of the community. In this case, the community information acquisition unit 131 acquires character or voice data (messages sent and received between users, voice of calls made between users, minutes of meetings, etc.) uttered by each of the multiple users from a predetermined communication service, for example.

[0038] The community information acquisition unit 131 extracts the content of each of the multiple users' comments by performing known analysis processing (natural language processing, voice recognition processing, etc.) on the acquired characters or voices. The community information acquisition unit 131 acquires community information that indicates the extracted content of comments as characteristics of the community.

[0039] 3(b), the community information acquisition unit 131 identifies, for example, the content associated with the tokens held by each of the multiple users on the blockchain as the characteristics of the community. In this case, the community information acquisition unit 131 acquires, for example, the tokens held by each of the multiple users (tokens associated with user IDs for identifying the users) from the blockchain.

[0040] The community information acquisition unit 131 acquires, for example, a unique token indicating the characteristics of a user. The unique token is information indicating the characteristics of a user who holds the unique token, for example, a SoulBound Token (SBT). The user's characteristics include, for example, personal information of the user, a user's behavior history, and the like. The unique token is guaranteed to indicate the characteristics of the user who holds it by not allowing it to be transferred between users on the blockchain. In addition, the community information acquisition unit 131 may acquire an NFT indicating the ownership of content such as images and music held by the user.

[0041] The community information acquisition unit 131 acquires community information that indicates the details (personal information, behavior history, owned content, etc.) associated with the acquired token as characteristics of the community.

[0042] Next, a process in which the information processing device 1 changes the content based on the community information will be described. Fig. 4 is a schematic diagram for explaining a process in which the information processing device 1 changes the content based on the community information.

[0043] The content acquisition unit 132 acquires the content to be changed that is stored in advance in the storage unit 12 of the information processing device 1 or in a storage unit of a device different from the information processing device 1. The content to be changed is, for example, content created by any one of a plurality of users who participate in a community, or content generated by a program for generating content (such as a machine learning model).

[0044] The content acquisition unit 132 acquires the changed content generated by changing the content to be changed based on the community information. The changed content is generated, for example, by the information processing device 1 or another device different from the information processing device 1 executing a predetermined program.

[0045] The content acquisition unit 132 generates, for example, an input sentence (also called an instruction sentence or a prompt) for causing a machine learning model, which is a program for changing the content, to change the content. The machine learning model in this embodiment is generated in advance by machine learning a large amount of digital data using a known deep learning process such as DNN (Deep Neural Network). The machine learning model receives digital data such as an image or music and an input sentence, and outputs digital data changed according to the input sentence. The machine learning model is stored in advance in the storage unit 12 or another device.

[0046] The content acquisition unit 132 generates an input sentence for causing the machine learning model to change the content, for example, based on the characteristics of the community indicated by the community information acquired by the community information acquisition unit 131. The content acquisition unit 132 applies information corresponding to the characteristics of the community to rules (templates, etc.) pre-stored in the storage unit 12, for example, to generate an input sentence indicating to change the color, orientation, pattern, etc. of the content that is an image, an input sentence indicating to change the lyrics, melody, voice, etc. of the content that is music, and the like.

[0047] The content acquisition unit 132 may generate an input sentence so as to change the content according to, for example, a word (such as "cute" or "cool") that appears more frequently than a predetermined value in the comments of multiple users indicated by the characteristics of the community. The content acquisition unit 132 may also generate an input sentence so as to change the content according to information (such as "I like realistic pictures," "I like calming music," etc.) that summarizes the comments of multiple users indicated by the characteristics of the community using a known analysis process. This allows the information processing system S to reflect the comments of multiple users participating in the community in the content.

[0048] The content acquisition unit 132 may generate an input sentence so as to change the content according to, for example, content (personal information, behavior history, owned content, etc.) associated with tokens held by multiple users indicated by the characteristics of the community that has a frequency of occurrence equal to or greater than a predetermined value (e.g., participation in a music event of a specific genre, ownership of an image of a specific subject, etc.). The content acquisition unit 132 may also generate an input sentence so as to change the content according to information (e.g., many users having a specific attribute, many users owning a specific content, etc.) obtained by aggregating the content associated with tokens held by multiple users indicated by the characteristics of the community using a known analysis process. This allows the information processing system S to reflect the content associated with tokens held by multiple users participating in the community in the content.

[0049] When the information processing device 1 executes a program for changing content, the generation unit 133 acquires the content acquired by the content acquisition unit 132, the input sentence generated by the content acquisition unit 132, and the machine learning model pre-stored in the storage unit 12. The generation unit 133 inputs the acquired content and the input sentence to the machine learning model, thereby generating digital data using the machine learning model. The content acquisition unit 132 acquires the digital data generated by the generation unit 133 as changed content.

[0050] When a program for changing the content is executed by another device different from the information processing device 1, the content acquisition unit 132 transmits the acquired content and the generated input sentence to the other device. The other device inputs the content and the input sentence transmitted by the information processing device 1 to a machine learning model, generates digital data using the machine learning model, and transmits the generated digital data to the information processing device 1. The content acquisition unit 132 acquires the digital data transmitted by the other device as changed content.

[0051] The content acquisition unit 132 may acquire multiple changed contents that are different from each other and are generated by changing one piece of content. In this case, the content acquisition unit 132 generates multiple input sentences for changing the changed contents that are at least partially different from each other by changing one piece of content, based on the community information. The content acquisition unit 132 acquires multiple changed contents that the generation unit 133 or other device generates using the content and multiple input sentences. This allows the information processing system S to generate multiple changed content candidates from one piece of content, based on the community information.

[0052] Next, a process in which the information processing device 1 receives evaluations of the changed content will be described. The output unit 134 outputs one or more changed contents acquired by the content acquisition unit 132 in association with the community. The acceptance unit 135 displays a reception screen for accepting evaluations of each of the one or more changed contents output by the output unit 134 on the information terminal 2 used by each of the multiple users participating in the community.

[0053] 5 is a schematic diagram of the information terminal 2 displaying an exemplary reception screen. The reception screen includes an area for receiving an evaluation of the post-change content from a user, and an area for receiving changes to the post-change content.

[0054] The evaluation is, for example, the degree of value of the changed content as judged by the user, and is represented by an evaluation index (number of stars on a five-point scale in the example of FIG. 5) indicating the level of evaluation specified by the user. The changes are changes that the user wishes to make to the changed content, and are represented by, for example, a character string specified by the user. The information terminal 2 transmits the evaluation index and changes specified on the reception screen to the information processing device 1.

[0055] The receiving unit 135 receives the evaluation index and the change content from the information terminal 2 used by each of the multiple users, and stores the received evaluation index and the change content in the storage unit 12. The receiving unit 135 may receive an evaluation of the post-change content without receiving a designation of the change content for the post-change content.

[0056] The information processing device 1 switches between a re-modification process for further modifying the modified content and a sales process for selling tokens associated with the modified content, depending on the evaluations of the modified content received from each of the multiple users. The information processing device 1 executes the sales process when the evaluation index of the modified content satisfies a predetermined sales condition, and executes the re-modification process when the evaluation index does not satisfy the sales condition. The sales condition is, for example, that the statistical value (average value, median value, etc.) of the evaluation index of the modified content received from the multiple users participating in the community is equal to or greater than a predetermined reference value.

[0057] 6 is a schematic diagram for explaining a re-modification process for modifying the modified content in response to evaluations by multiple users. Here, the modified content evaluated by the users is referred to as a first modified content, and the modified content generated by the re-modification process is referred to as a second modified content.

[0058] When the evaluation index of the first changed content accepted by the accepting unit 135 does not satisfy the sales conditions (for example, when the statistical value of the evaluation index is less than a reference value), the content acquisition unit 132 acquires a second changed content generated by changing the first changed content based on the community information and the evaluation index.

[0059] The content acquisition unit 132 generates an input sentence for causing the machine learning model to change the first post-change content, based on, for example, the characteristics of the community indicated by the community information and the evaluation index.

[0060] For example, in the above-mentioned process of generating an input sentence for modifying content based on the characteristics of the community indicated by the community information, the content acquisition unit 132 generates the input sentence such that the smaller the evaluation index (lower the evaluation), the greater the degree of modification of the first modified content, and the larger the evaluation index (higher the evaluation), the less the degree of modification of the first modified content.

[0061] Furthermore, when the accepting unit 135 accepts the change content of the first changed content, the content acquiring unit 132 may acquire the second changed content generated by changing the first changed content based on the community information and the change content. In this case, the content acquiring unit 132 generates the input sentence so as to include the change content.

[0062] The content acquisition unit 132 acquires, as the second changed content, digital data generated by the generation unit 133 or another device using the first changed content and the input sentence. The reception unit 135 may again receive evaluations of the second changed content from multiple users participating in the community. The information processing device 1 executes the sales process using the second changed content as the changed content. This allows the information processing system S to reflect the evaluations input by multiple users participating in the community in the content.

[0063] 7 is a schematic diagram for explaining a selling process for selling a token associated with a modified content. The modified content to be sold is a modified content that has not been modified again or a modified content that has been modified again (a second modified content).

[0064] When the evaluation index of the changed content accepted by the accepting unit 135 satisfies the sales condition (for example, when the statistical value of the evaluation index is equal to or greater than a reference value) or when a re-changing process is performed on the changed content, the output unit 134 outputs sales information for selling a token associated with the changed content on the blockchain. When the evaluation index of some changed content among the multiple changed contents satisfies the sales condition, the output unit 134 may output sales information for selling a token associated with the part of the changed content.

[0065] The output unit 134 outputs issuing information for issuing a token associated with the changed content on the blockchain. The output unit 134 generates, for example, a token associated with the changed content. The token is associated with the changed content by including, for example, access information such as a uniform resource identifier (URI) for accessing the changed content stored in a predetermined storage device, or by including the changed content itself.

[0066] The output unit 134 transmits issuance information for adding a transaction indicating a token associated with the changed content, a token ID for identifying the token, and an owner ID for identifying the owner of the token (here, the community) to the blockchain. The blockchain adds the transaction according to the issuance information. As a result, the output unit 134 causes the blockchain to issue a token with the community as the owner.

[0067] After the token associated with the changed content is issued, the output unit 134 outputs sales information for selling the token associated with the changed content at a predetermined sales outlet. The sales outlet is, for example, a platform such as a website for buying and selling tokens. The output unit 134 transmits, for example, sales information for starting the sale of the token to the sales outlet server 3. The sales information is, for example, information that associates the token ID of the token to be sold with the holder ID of the holder of the token.

[0068] The sales office server 3 starts selling tokens at a predetermined price on the blockchain in accordance with the sales information received from the information processing device 1. The price at which the tokens are sold may be specified by the token holder, or may be automatically determined by the output unit 134 or the sales office server 3. When a potential purchaser wishes to purchase a token, the sales office server 3 transfers assets corresponding to the token price from the potential purchaser to the token holder, and also transfers the token from the token holder to the potential purchaser. When no purchase of the token is desired, the sales office server 3 continues selling the tokens.

[0069] Next, a re-changing process in which the information processing device 1 further changes the changed content based on the sales status after the sale of the tokens has started will be described. Fig. 8 is a schematic diagram for explaining the re-changing process in which the changed content is changed based on the sales status.

[0070] The sales status acquisition unit 136 acquires sales status information indicating the sales status of the token associated with the changed content from the storage unit 12 or another device (e.g., the sales outlet server 3) different from the information processing device 1 at a predetermined timing (daily, weekly, etc.). The sales status acquisition unit 136 may also acquire sales status indicating the sales status of the token associated with the changed content and other tokens different from the token. The other tokens are tokens associated with a predetermined content different from the changed content.

[0071] The sales status may include, for example, whether the token is on sale (whether it has been purchased), the current or final price of the token, and the sales period. The sales period may be represented, for example, by the dates when the sale begins and ends. The sales status is not limited to the specific information shown here, and may include other information related to the sale of the token.

[0072] The content acquisition unit 132 generates an input sentence for causing the machine learning model to change the changed content, based on the community information acquired by the community information acquisition unit 131 and the sales status indicated by the sales status information acquired by the sales status acquisition unit 136. Here, the changed content for which the sales status has been acquired is referred to as a first changed content, and the changed content generated by the re-change process is referred to as a second changed content.

[0073] In the above-mentioned process of generating an input sentence for changing the content based on the characteristics of the community indicated by the community information, for example, the content acquisition unit 132 generates an input sentence such that the degree of change to the first changed content is increased as the time elapsed from the start of the sale indicated by the token sales status is longer, and the degree of change to the first changed content is decreased as the time elapsed from the start of the sale indicated by the token sales status is shorter. This allows the information processing system S to flexibly switch the changes to the content according to the token sales status.

[0074] Furthermore, the content acquisition unit 132 may generate an input sentence for causing the machine learning model to change the first changed content based on the sales status of the token and other tokens different from the token. For example, on the condition that the sales status indicates that the token is not selling and the sales status indicates that the other tokens have been sold, the content acquisition unit 132 generates an input sentence so as to incorporate elements of other content associated with the other tokens (color, orientation, etc. of an image, or lyrics, melody, etc. of music) into the first changed content. This allows the information processing system S to make it easier for the token to be purchased by modifying the first changed content so as to incorporate elements of other content that is selling well.

[0075] Furthermore, the content acquisition unit 132 may generate an input sentence for causing the machine learning model to change the first changed content based on the evaluation index of the first changed content in addition to the community information and the sales status. This allows the information processing system S to change the content so that it is highly rated by multiple users participating in the community and has a good sales status.

[0076] The content acquisition unit 132 acquires, as the second changed content, the digital data generated by the generation unit 133 or another device using the first changed content and the input sentence. The reception unit 135 may again receive evaluations of the second changed content from multiple users who participate in the community. The information processing device 1 executes the sales process again using the second changed content as the changed content.

[0077] [Information processing method flow] 9 is a diagram showing a flowchart of an exemplary information processing method executed by the information processing device 1 according to this embodiment. The community information acquisition unit 131 acquires community information indicating characteristics of the community in response to a predetermined start operation (selection of a start button, etc.) being performed by any one of a plurality of users participating in the community on the information terminal 2 (S11).

[0078] The content acquisition unit 132 acquires (S12) the content to be changed that is stored in advance in the storage unit 12 of the information processing device 1 or in a storage unit of a device other than the information processing device 1. The content acquisition unit 132 acquires (S13) the changed content that is generated by changing the content to be changed based on the community information.

[0079] The output unit 134 outputs one or more pieces of post-change content acquired by the content acquisition unit 132 in association with the community (S14).

[0080] The receiving unit 135 receives evaluations of one or more changed contents output by the output unit 134 at the information terminals 2 used by each of the multiple users participating in the community (S15). The receiving unit 135 receives the evaluation index and the change details from the information terminals 2 used by each of the multiple users, and stores the received evaluation index and the change details in the storage unit 12.

[0081] If the evaluation index of the post-change content does not satisfy the predetermined sales condition (NO in S16), the content acquisition unit 132 executes a re-change process for changing the post-change content based on the community information and the evaluation index (S17).

[0082] If the evaluation index of the changed content satisfies a predetermined sales condition (YES in S16), or if the re-changing process in step S17 is performed, the output unit 134 outputs issuance information for issuing a token associated with the changed content on the blockchain (S18). After the token associated with the changed content is issued, the output unit 134 outputs sales information for selling the token associated with the changed content at a predetermined sales outlet (S19).

[0083] [Effects of the embodiment] According to the information processing system S of this embodiment, the information processing device 1 modifies the original content based on the community information indicating the characteristics of the community, and outputs the modified content in association with the community. This allows the information processing system S to generate content that reflects the overall tendency of the community in which multiple users participate.

[0084] Furthermore, this invention will make it possible to contribute to Goal 9 of the United Nations' Sustainable Development Goals (SDGs), which is to "build resilient infrastructure, promote industry, innovation and infrastructure."
