DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Embodiment 1 First, with reference to FIG. 1, a schematic configuration of the ingredient information proposal system 100 according to the first embodiment will be described. FIG. 1 is a block diagram showing a schematic configuration of the ingredient information proposal system 100 according to the first embodiment. As shown in FIG. 1, the ingredient information proposal system 100 includes a database 10, an information processing device 20, and a plurality of user terminals 30, and is a system for proposing information about ingredients to the users of the user terminals 30 by the information processing device 20. For example, the ingredient information proposal system 100 proposes information about a combination of ingredients used by the users of the user terminals 30 when making a dish to the users of the user terminals 30 by the information processing device 20. In the ingredient information proposal system 100, the database 10, the information processing device 20, and the plurality of user terminals 30 are electrically connected to each other by wire or wirelessly so that information can be communicated between them. Note that the information processing device may include some or all of the functions of the database 10 and the user terminal 30 described below, or each user terminal may include some or all of the functions of the database 10 and the information processing device 20.

[0010] The database 10 includes an ingredient information storage unit 11, a history information storage unit 12, and a preference information storage unit 13, and stores information used when the information processing device 20 proposes information about ingredients to the user of each user terminal 30. The ingredient information storage unit 11 stores ingredient information about a plurality of ingredients. For example, the ingredient information storage unit 11 stores ingredient information including one or more of the following: information about how to eat each of a plurality of ingredients, information about the amount of nutrients each of a plurality of ingredients has, information about combinations of a plurality of ingredients, information about foods that can be made using combinations of a plurality of ingredients, information about a plurality of foods, information about cooking methods using combinations of a plurality of ingredients, information about the seasons of a plurality of ingredients, information about combinations of one or more ingredients and one or more foods, information about combinations of a plurality of foods, information about food combinations of a plurality of foods, and information about ingredients and foods under the management of each user.

[0011] Moreover, the ingredient information storage unit 11 stores a plurality of combinations of ingredients, at least some of which are different from each other. In the first embodiment, the food refers to a food that has been made into a state that can be orally ingested by a user by cooking or processing one or more ingredients, and may be a food made by a user cooking ingredients, a food that is sold as a finished product, or a semi-finished product, such as a frozen food that is completed by a user performing only a portion of the cooking steps. In the first embodiment, the ingredients include vegetables, meat, fish, etc. that have been processed by cutting, parboiling, peeling, etc. In the first embodiment, the ingredients include seasonings and sauces, etc.

[0012] The history information storage unit 12 stores history information related to the usage history when the user of each user terminal 30 used the ingredient information proposal system 100. For example, the history information storage unit 12 stores history information including one or more pieces of information related to the content of information that the information processing device 20 decided to propose to the user of each user terminal 30, information related to the content of information output by the information processing device 20 to the user of each user terminal 30, information related to the date and time when the information processing device 20 output information to the user of each user terminal 30, information related to ingredients that the user of each user terminal 30 decided to receive from the ingredients related to the information output by the information processing device 20 to the user of each user terminal 30, information related to the date and time when the user of each user terminal 30 decided to receive the ingredients, and information related to the date and time when the user of each user terminal 30 received the ingredients, and identification information for identifying the user of each user terminal 30, for each user of the user terminal 30. Note that receiving the ingredients means that the user puts the ingredients or food under his / her own control by purchasing, delivering, taking home, etc. In addition, each user terminal 30 may be able to search and view ingredient information in the database 10, and in such a case, the above-mentioned history information may be stored by linking information regarding the ingredient information searched and viewed by each user terminal 30 to each user of the user terminal 30.

[0013] The preference information storage unit 13 stores preference information regarding the preferences of the user of each user terminal 30 for ingredients and food. For example, the preference information storage unit 13 stores, for each user of the user terminal 30, preference information including one or more pieces of information on the user's preference for each ingredient, information on the user's preference for each food, information on the user's preference for seasoning, information on the user's preference for cooking methods, information on the user's preference for the amount of food eaten, information on the user's preference for food combinations, and evaluation information on suggested information previously proposed by the information processing device 20, and identification information for identifying the user of each user terminal 30.

[0014] For example, the information regarding the user's preference for each ingredient includes one or more of information indicating the result of the user's evaluation of the level of preference for a particular ingredient, information indicating the user does not evaluate the level of preference for a particular ingredient, information regarding the user's purchase history of a particular ingredient, information regarding the user's receipt of a particular ingredient, and information indicating the number or frequency of access to information regarding a particular ingredient via the user terminal 30. Similarly, for example, the information regarding the user's preference for each food item includes one or more of information indicating the result of the user's evaluation of the level of preference for a particular food item, information indicating the user does not evaluate the level of preference for a particular food item, information regarding the user's purchase history of a particular food item, information regarding the user's receipt of a particular food item, and information indicating the number or frequency of access to information regarding a particular food via the user terminal 30.

[0015] For example, information about a user's seasoning preferences includes one or more of information about the strength of flavor of a favorite food, information about the spiciness of a favorite food, information about a favorite taste, information about a favorite seasoning, and information about a favorite combination of seasoning and ingredients. For example, information about a user's cooking method preferences includes one or more of information about preferences for the way ingredients are cut, information about preferences for the way ingredients are heated, and information about preferences for the heating time of ingredients. For example, information about the way ingredients are cut includes information about the size and shape of the ingredients when they are cut. In the first embodiment, "preferences" for ingredients and foods include a judgment of whether ingredients and foods can be ingested based on constitution, beliefs, doctor's advice, etc.

[0016] The database 10 may be configured to acquire and store this information from the information processing device 20, may be configured to acquire and store this information from the user terminal 30, or may be configured to acquire this information from another device connected via a network (not shown). When acquiring this information from the user terminal 30, the database 10 may be configured to acquire the information based on information generated by application software used by the user terminal 30 and information collected by the application software.

[0017] The information processing device 20 includes a processor 21, a storage unit 22, an auxiliary storage unit 23, a communication device 24, and an input / output interface 25, and is configured so that the processor 21 reads and executes programs stored in the storage unit 22 and the auxiliary storage unit 23. The processor 21 includes an information acquisition unit 211, a recommendation determination unit 212, and a result output unit 213. The information acquisition unit 211 acquires various information from the database 10 and each user terminal 30. For example, the information acquisition unit 211 includes an ingredient information acquisition unit 211a, a history information acquisition unit 211b, and a preference information acquisition unit 211c.

[0018] The ingredient information acquiring unit 211a acquires, from the ingredient information storage unit 11 of the database 10, ingredient information stored in the ingredient information storage unit 11.

[0019] The history information acquisition unit 211b acquires history information stored in the history information storage unit 12 from the database 10, and acquires information from each user terminal 30. For example, the history information acquisition unit 211b acquires history information related to the usage history when the ingredient information recommendation system 100 is used from each user terminal 30 based on the user's input operation to an input device (not shown) of each user terminal 30. For example, each user terminal 30 is equipped with an input device such as a touch panel, physical buttons, a keyboard, a mouse, etc. The information acquired by the history information acquisition unit 211b from each user terminal 30 is similar to the information stored in the history information storage unit 12, and therefore a description thereof will be omitted.

[0020] In addition, the history information acquisition unit 211b may be configured to acquire history information from only one of the history information storage unit 12 and each user terminal 30, or may be configured to acquire history information from both the history information storage unit 12 and each user terminal 30, or may be configured to acquire some of the information included in the history information from one of the history information storage unit 12 and each user terminal 30, and acquire other information included in the history information from the other of the history information storage unit 12 and each user terminal 30.

[0021] The preference information acquiring unit 211c acquires information stored in the preference information storage unit 13 of the database 10 and information from each user terminal 30. For example, the preference information acquiring unit 211c acquires from each user terminal 30 history information related to the usage history when the ingredient information recommendation system 100 is used, based on the user's input operation to an input device (not shown) of each user terminal 30. The information acquired by the preference information acquiring unit 211c from each user terminal 30 is similar to the information stored in the preference information storage unit 13, and therefore a description thereof will be omitted.

[0022] In addition, the preference information acquisition unit 211c may be configured to acquire preference information from only one of the preference information storage unit 13 and each user terminal 30, or may be configured to acquire preference information from both the preference information storage unit 13 and each user terminal 30, or may be configured to acquire some of the information included in the preference information from one of the preference information storage unit 13 and each user terminal 30, and acquire other information included in the preference information from the other of the preference information storage unit 13 and each user terminal 30.

[0023] The recommendation determination unit 212, which serves as an ingredient information suggestion unit, determines suggested information to be suggested to the user of each user terminal 30, based on the information acquired by the information acquisition unit 211. For example, the recommendation determination unit 212 determines to suggest suggested information on a combination of any two or more ingredients among a plurality of ingredients to each user of the user terminal 30, based on the ingredient information acquired by the ingredient information acquisition unit 211a and the preference information acquired by the preference information acquisition unit 211c. For example, the suggested information includes one or more pieces of information among information indicating a combination of a plurality of ingredients, cooking information on a cooking method for cooking food using a plurality of ingredients, information indicating a combination of a plurality of foods, and information indicating a combination of a plurality of ingredients and food.

[0024] For example, the information indicating a combination of multiple ingredients is information indicating a combination of multiple ingredients that a user takes in one meal. Also, for example, the information indicating a combination of multiple ingredients is information indicating a combination of multiple ingredients that is proposed to the user for new purchase. Also, for example, the information indicating a combination of multiple ingredients is information indicating a combination of multiple ingredients that is proposed to the user for new purchase and ingredients that the user already has under his / her control.

[0025] For example, cooking information about a cooking method for food using multiple ingredients is information indicating the amounts of multiple ingredients used in the dish and information indicating the cooking steps using these multiple ingredients. Note that the information indicating the cooking steps using these multiple ingredients may be information indicating the entire cooking steps from the start to the end of cooking using these multiple ingredients, or may be information indicating a part of the cooking steps. For example, the information indicating the cooking steps is information including the cutting manner of the ingredients, the heating method of the ingredients, the heating time of the ingredients, and the seasoning of the ingredients.

[0026] For example, the information indicating a combination of multiple foods is information indicating a combination of multiple foods that is newly proposed to the user for purchase. Also, for example, the information indicating a combination of multiple foods is information indicating a combination of one or more foods that is newly proposed to the user for purchase and foods that the user already has under his / her control. For example, the information indicating a combination of multiple foods is information indicating a meal kit that is a combination of multiple foods used to make a specific food that is newly proposed to the user for purchase.

[0027] For example, the information indicating a combination of multiple ingredients and foods is information indicating a combination of one or more ingredients proposed to the user for new purchase and one or more foods proposed to the user for new purchase. Also, for example, the information indicating a combination of multiple ingredients and foods is information indicating a combination of one or more ingredients proposed to the user for new purchase and one or more foods that the user already has under his / her control. Also, for example, the information indicating a combination of multiple ingredients and foods is information indicating a combination of one or more ingredients that the user already has under his / her control and one or more foods proposed to the user for new purchase.

[0028] The result output unit 213 outputs the proposal information determined to be proposed to each user by the recommendation determination unit 212 to the user terminal 30 used by each user. For example, the result output unit 213 displays the proposal information on a display device (not shown) provided in each user terminal 30. For example, the display device of such a user terminal 30 is configured by a liquid crystal display device or the like.

[0029] For example, the storage unit 22 is configured by a non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM.

[0030] For example, the auxiliary storage unit 23 is composed of a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD, or the like.

[0031] The communication device 24 performs various processes for the information processing device 20 to communicate information with the database 10 and each user terminal 30 via the input / output interface 25 .

[0032] In addition, the hardware configuration of the information processing device 20 is not limited to the above-mentioned one, and may be configured to realize each function including the information acquisition unit, recommendation determination unit, and result output unit by a dedicated processing circuit configured, for example, by a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, a system LSI (Large-Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a combination of these.

[0033] Next, the details of the process performed by the information processing device 20 will be described with reference to Figs. 2 to 5. Fig. 2 is a flowchart showing the process performed by the information processing device 20 according to the first embodiment. As shown in Fig. 2, when the process starts, the information processing device 20 acquires information used in the process from either one or both of the database 10 and the specific user terminal 30 used by the specific user (step ST1). In this process, the information processing device 20 acquires ingredient information by the ingredient information acquisition unit 211a, acquires history information by the history information acquisition unit 211b, and acquires preference information by the preference information acquisition unit 211c. In the first embodiment, the specific user is also referred to as a specific user, and the specific user terminal 30 is also referred to as a specific user terminal.

[0034] After performing the process of step ST1, the information processing device 20 determines the contents of the recommendation (step ST2). In this process, the information processing device 20 determines proposed information related to a combination of multiple ingredients to be proposed to the specific user based on the ingredient information acquired by the ingredient information acquisition unit 211a, the history information acquired by the history information acquisition unit 211b, and the preference information acquired by the preference information acquisition unit 211c. Specifically, the information processing device 20 determines to propose new proposed information to the specific user, based on the history information acquired by the history information acquisition unit 211b, so that the new proposed information is at least partially different from the proposed information last output to the specific user by the result output unit 213. In other words, the recommendation determination unit 212 determines to newly propose to the specific user the proposed information that is at least partially different from the proposed information last proposed to the specific user, out of first proposed information related to a combination of two or more ingredients among the multiple ingredients and second proposed information related to a combination of two or more ingredients among the multiple ingredients and differing from the first proposed information in at least a part of the combination of ingredients.

[0035] 3 is a diagram showing items when the information processing device 20 according to the first embodiment changes the contents of a meal kit as a combination of multiple ingredients. As shown in the left column of FIG. 3, for example, the information processing device 20 acquires previous output information, which is information showing the contents of the meal kit last output to a specific user by the result output unit 213, based on the acquired history information, and determines to propose new proposal information to the specific user so that the contents of the meal kit shown in the previous output information are at least partially different from the contents of the meal kit shown in the previous output information by one or more of replacing at least some ingredients, adding ingredients, changing at least some seasonings, changing the cutting mode of ingredients, changing the size of ingredients, changing the amount, and changing the total amount. Details of the contents of each item are as shown in the right column of FIG. 3, so description will be omitted.

[0036] Furthermore, the information processing device 20 is not limited to a device that changes the contents of the meal kit when proposing new proposed information to a specific user so that the new proposed information is at least partially different from the proposed information last output to the specific user by the result output unit 213. For example, when the proposed information is information including a combination of a meal kit and food, the information processing device 20 may be configured to propose new proposed information to a specific user so that the new proposed information is at least partially different from the proposed information last output to the specific user by the result output unit 213 by changing at least a portion of the food to be combined in the meal kit, in other words, the food to be added to the meal kit.

[0037] FIG. 4 is a diagram showing items when the information processing device 20 according to the first embodiment changes the food to be added to the meal kit. As shown in the left column of FIG. 4, for example, the information processing device 20 acquires previous output information, which is information showing the meal kit last output to the specific user by the result output unit 213 and the food added to the meal kit based on the acquired history information, and determines to propose new proposal information to the specific user so that the food added to the meal kit shown in the previous output information is at least partially different from the food added to the meal kit shown in the previous output information by one or more of replacing at least some ingredients, adding ingredients, changing at least some seasonings, changing the cutting manner of ingredients, changing the size of ingredients, changing the amount, and changing the total amount. Details of the contents of each item are as shown in the right column of FIG. 4, so explanations are omitted.

[0038] In addition, the information processing device 20 may be configured to propose new suggested information to a specific user by selecting new food items as food items to be added to such a meal kit, so that the new suggested information is at least partially different from the suggested information last output by the result output unit 213 to the specific user.

[0039] 5 is a diagram showing information used when information processing device 20 according to embodiment 1 selects foods to add to a meal kit. For example, new foods are selected based on information included in information acquired by information acquisition unit 211, regarding combinations of meal kits and foods that suit the preferences of a specific user, combinations of general meal kits and foods, foods that suit the preferences of a specific user, foods that are general popular products, foods already owned by the specific user, foods made by cooking with ingredients owned by the specific user, and foods not in the history of the specific user.

[0040] For example, foods that are not in the history of a specific user are foods that the information processing device 20 has never suggested to the specific user, foods for which the specific user has no history of searching for ingredient information in the database 10 using the specific user terminal, foods for which the specific user has no history of viewing ingredient information in the database 10 using the specific user terminal, etc.

[0041] In addition, in this process, the recommendation determination unit 212 may be configured to calculate similarities between multiple pieces of proposed information, and determine to newly propose to the specific user the proposed information having a lower similarity to the proposed information last proposed to the specific user between first proposed information related to a combination of two or more ingredients from a plurality of ingredients and second proposed information related to a combination of two or more ingredients from a plurality of ingredients and differing in at least part of the ingredient combination from the first proposed information.

[0042] Furthermore, in this process, the recommendation determination unit 212 may be configured to acquire information regarding evaluations by the specific user of a plurality of pieces of proposed information and information regarding an evaluation threshold for determining whether or not the proposed information can be suggested to the specific user, and to decide to newly propose one of the first proposed information and the second proposed information to the specific user based on the date and time when first proposed information regarding a combination of two or more ingredients from a plurality of ingredients and second proposed information regarding a combination of two or more ingredients from a plurality of ingredients and which differs from the first proposed information in at least a part of the ingredient combinations, were last output to the specific user by the result output unit 213, and the preference information acquired by the preference information acquisition unit 211c. Specifically, in this process, if the preference information acquired by the preference information acquisition unit 211c indicates that the specific user's rating of the first proposed information and the specific user's rating of the second proposed information are both equal to or higher than a preset rating, the recommendation determination unit 212 decides to newly propose to the specific user one of the first proposed information and the second proposed information, whichever was last output to the specific user by the result output unit 213 on an older date and time.

[0043] In addition, in this process, the recommendation determination unit 212 may be configured to determine that, when the difference between the date and time when the first proposed information was last output to the specific user by the result output unit 213 and the date and time when the second proposed information was last output to the specific user is within a predetermined time period, the first proposed information or the second proposed information, whichever has been more highly rated by the specific user, should be newly proposed to the specific user.

[0044] After performing the process of step ST2, the information processing device 20 outputs proposed information, which is the content decided to be proposed by the recommendation decision unit 212 (step ST3).

[0045] As described above, the ingredient information proposal system 100 according to the first embodiment includes an ingredient information acquisition unit that acquires ingredient information about a plurality of ingredients; a preference information acquisition unit that acquires preference information about a user's preferences; a proposal information determination unit that determines proposal information about a combination of any two or more ingredients among a plurality of ingredients to be proposed to the user based on the ingredient information acquired by the ingredient information acquisition unit and the preference information acquired by the preference information acquisition unit; an output unit that outputs to the user the proposal information determined to be proposed by the proposal information determination unit; and a history information acquisition unit that acquires history information about the history of the proposal information determined by the proposal information determination unit. The proposal information determination unit further determines, based on the history information acquired by the history information acquisition unit, to propose new proposal information to the user such that the new proposal information is at least partially different from the proposal information last output to the user by the output unit.

[0046] Configured in this way, the ingredient information proposal system 100 according to the first embodiment outputs new proposal information that is at least partially different from the proposal information about ingredient combinations last proposed to the user, thereby preventing the user from becoming bored with ingredients. In addition, it is possible to receive proposals from a plurality of ingredient and food combinations that match the user's preferences, and the proposed ingredients and foods broaden the user's range of meals while preventing boredom, thereby encouraging the user to continue using the information provision service and the ingredient and food provision service.
