1. Service for Presenting a User's Wine Preferences The applicant proposes a service for presenting a user's wine preferences. In this service, the user's wine preferences are identified by simply answering a few questions on the user device, so that the user can easily know his or her own wine preferences. In addition, every time the user drinks wine, the user updates the evaluation of the wine he or she has drunk by rating the wine, and the evaluations of other wines having attributes similar to the wine he or she has drunk are also updated. This makes it possible to automatically update the wine preferences.

The following describes an embodiment of the present invention with reference to the drawings.

FIG. 1A shows a screen 100 displayed on a user device. A user device refers to any device used by a user. Examples of user devices include, but are not limited to, a tablet terminal or a smartphone.

Screen 100 is an example of a screen that displays questions to be answered by the user to present the user's wine preferences. In the embodiment shown in FIG. 1A, screen 100 includes a choice area 101 that displays options to be selected by the user, a "Next" button 102 for moving to the next question, and a "Back" button 103 for returning to the previous question. Each option displayed in choice area 101 is configured to be selectable. "Next" button 102 and "Back" button 103 are configured to be selectable.

In the embodiment shown in FIG. 1A, three options are displayed in the option area 101: "Carbonara," "Peperoncino," and "Neither of them is my favorite." Note that, in the embodiment shown in FIG. 1A, an example in which the number of options displayed in the option area 101 is three has been described, but the present invention is not limited to this. The number of options displayed in the option area 101 may be any number equal to or greater than two. For example, in another question, four or more options may be displayed in the option area 101. Also, for example, multiple options may be displayed in the option area 101 in a manner that allows multiple options to be selected.

When the user selects one of the multiple options displayed in the option area 101, the user can select the "Next" button 102, which causes the screen 100 to transition to a screen displaying the next question (not shown). In this way, the user answers the questions that are displayed one after the other, and selects and inputs multiple answers. This makes it possible to collect basic information for identifying the user's wine preferences. The number of questions displayed in succession is arbitrary. For example, the number of questions displayed in succession may be 5, 10, 15, 30, or 50.

Also, before the user starts answering the questions, a screen for selecting between an advanced mode for advanced users who have wine knowledge and a beginner mode for novice users who have no wine knowledge may be displayed on the user device. The questions displayed in the advanced mode may be different from the questions displayed in the beginner mode. For example, the questions displayed in the beginner mode may be simple questions that can be selected relatively easily, and the questions displayed in the advanced mode may be complex questions that can be answered by inputting detailed information about wine. In this way, for beginner users with little wine knowledge, questions that can be easily answered even without wine knowledge are presented, and answers are received from the beginner users, thereby making it possible to extract the maximum amount of information about the user's wine preferences from the beginner users, and for advanced users with a lot of wine knowledge, more advanced and highly specialized questions are presented, and answers are received from the advanced users, thereby making it possible to extract the maximum amount of information about the user's wine preferences from the advanced users.

FIG. 1B shows a screen 110 displayed on the user device. Screen 110 is an example of a screen that presents the user's wine preferences. Screen 110 is displayed on the user device after the user has answered multiple questions such as those shown in FIG. 1A.

In the embodiment shown in FIG. 1B, the user's name is "Taro" and the user's wine preference is wines that are classified as a "refreshing fruity" flavor type. In addition, Sauvignon Blanc (New Zealand) is shown as a recommended wine from among wines that are classified as "refreshing fruity."

Based on the user's answers to the multiple questions (i.e., input from the user), the user's wine preference (match) is calculated and assigned to each of the multiple wines. The user can check the preference for each wine on a screen that lists the multiple wines. In the embodiment shown in FIG. 1B, the screen 110 shows a match of "80%" for Sauvignon Blanc (New Zealand).

Figure 1C shows a screen 120 displayed on the user device. Screen 120 is an example of a screen for the user to input a rating for a wine they have drunk.

In the embodiment shown in FIG. 1C, the screen 120 includes a wine information area 121 in which information about the wine drunk by the user is displayed, a rating input area 122 in which the user can input a rating for the wine drunk, a comment input area 123 in which the user can input a comment about the wine drunk, and a registration button 124 for registering the input information.

In the embodiment shown in FIG. 1C, the wine information area 121 displays the brand of wine drunk by the user, "Villa Maria Private Vin Sauvignon Blanc 2019", the origin, "New Zealand", the variety, "Sauvignon Blanc", and the taste type, "refreshing fruity". In the embodiment shown in FIG. 1C, the evaluation point input area 122 is configured to allow the evaluation point to be selected and input using a pull-down menu, but the present invention is not limited to this. For example, the evaluation point input area 122 may be configured to allow a number to be directly input as the evaluation point.

In this way, the user can keep a record of the wines he or she has drunk by inputting information on the screen 120, and can also give the wines he or she has drunk a rating. The input rating not only affects the rating (i.e., the degree of match) of the wine rated by the user, but also affects the rating (i.e., the degree of match) of other wines that have attributes that at least partially match multiple attributes (e.g., flavor type, origin, variety) of the wine rated by the user.

For example, in the embodiment shown in FIG. 1C, the evaluation score of the wine "Villa Maria Private Vin Sauvignon Blanc 2019" evaluated by the user affects other wines that belong to the same taste type "refreshing fruity" as the wine "Villa Maria Private Vin Sauvignon Blanc 2019" evaluated by the user, other wines from the same region, and other wines of the same variety. When the evaluation score of the wine evaluated by the user is relatively high, the evaluation score of the wine has a positive effect on other wines that have attributes that at least partially match the attributes of the wine evaluated by the user (i.e., acts to raise the evaluation of those other wines), and when the evaluation score of the wine evaluated by the user is relatively low, the evaluation score of the wine has a negative effect on other wines that have attributes that at least partially match the attributes of the wine evaluated by the user (i.e., acts to lower the evaluation of those other wines).

2. Configuration of a System for Realizing a Service Presenting a User's Wine Preferences FIG. 2 shows an example of the configuration of a system 200 for realizing a service presenting a user's wine preferences.

2, the system 200 includes a computer system 210 managed by a company that provides a service for presenting users' wine preferences, and user devices 220 ₁ to 220 _N. The computer system 210 is configured to be able to communicate with each of the user devices 220 ₁ to 220 _N via the Internet 230, where N is an integer equal to or greater than 1.

The computer system 210 is an information processing system that executes processing for a company that provides a service that presents a user's wine preferences. In the embodiment shown in FIG. 2, the computer system 210 includes an interface unit 211, a processor unit 212 including one or more central processing units (CPUs), and a memory unit 213. The computer system 210 may further include a display unit, an input unit, and the like. The hardware configuration of the computer system 210 is not particularly limited as long as it can realize its functions, and may be configured as a single machine or a combination of multiple machines.

The interface unit 211 controls communications with each of the user devices 220 ₁ to 220 _N.

The memory unit 213 stores programs required to execute processing and data required to execute the programs. There is no restriction on how the programs are stored in the memory unit 213. For example, the programs may be pre-installed in the memory unit 213. Alternatively, the programs may be installed in the memory unit 213 by being downloaded via a network such as the Internet 230, or may be installed in the memory unit 213 via a storage medium such as an optical disk or USB.

The processor unit 212 controls the operation of the entire computer system 210. The processor unit 212 reads out a program stored in the memory unit 213 and executes the program. This allows the computer system 210 to function as a device that executes desired steps, and the processor unit 212 of the computer system 210 can operate as a means for achieving a desired function.

In the embodiment shown in FIG. 2, the computer system 210 is connected to a database section 240. The database section 240 includes a wine database section 241 and a user database section 242.

Each of the user devices 220 ₁ to 220 _N is configured to be able to communicate with the computer system 210 via the Internet 230. Each of the user devices 220 ₁ to 220 _N may include an interface unit, a processor unit, a memory unit, a display unit, and an input unit. For example, each of the user devices 220 ₁ to 220 _N may be a portable wireless terminal such as a mobile phone, a smartphone, or a tablet terminal, or may be a personal computer such as a laptop PC or a notebook PC.

2, each of the user devices 220 ₁ to 220 _N is described as being capable of communicating with the computer system 210 via the Internet 230, but the present invention is not limited thereto. Any type of network may be used in place of the Internet 230.

In the embodiment shown in FIG. 2, the database unit 240 is provided outside the computer system 210, but the present invention is not limited to this. The database unit 240 can also be provided inside the computer system 210. The configuration of the database unit 240 is not limited to a specific hardware configuration. For example, the database unit 240 may be configured as a single hardware component, or may be configured as multiple hardware components. For example, the database unit 240 may be configured as a single external hard disk device of the computer system 210, or may be configured as cloud storage connected via a network.

Figure 3A shows an example of the configuration of information stored in the wine database section 241.

The wine database section 241 stores information about wine. The information about wine can be identified by information for identifying the wine (wine ID). The information about wine includes, but is not limited to, the wine brand, harvest year, flavor type, origin, variety, etc.

A wine taste type is the name of a group into which multiple wines are pre-classified based on elements of wine taste that have a particularly large influence on preference (e.g., fruitiness, acidity, sweetness, etc.). Therefore, information about wines stored in the wine database unit 241 can be grouped by taste type. Wine taste types include, but are not limited to, "refreshing fruity," "pure fruity," and "sweet dessert," for example.

The wine's place of origin is the name of a group into which multiple wines are pre-classified, for example, based on "European Union wine growing zones." The information about wines stored in the wine database unit 241 can be grouped by place of origin based on the place of origin of the wine.

The wine variety is the name of a group into which multiple wines are pre-classified based on the flavor of the wine, etc. The information on wines stored in the wine database unit 241 can be grouped by variety based on the wine variety. Examples of grouping based on wine variety include, but are not limited to, "Pinot Noir" and "Cabernet Sauvignon."

Figure 3B shows an example of the configuration of information stored in the user database section 242.

The user database unit 242 stores information about users. The information about users can be identified by information for identifying the users (user ID). The information about users includes, but is not limited to, the user's name, sex, date of birth, telephone number, email address, information indicating the cumulative number of wines previously evaluated, evaluation points for taste type, evaluation points for origin, evaluation points for variety, score allocation for each wine, information about wines previously evaluated, and the like. The information about wines previously evaluated can be identified by information for identifying wines (wine ID). The information about wines previously evaluated includes, but is not limited to, evaluation points for wines input by the user (i.e., evaluation points for wines drunk by the user), and the like.

3. Processing Executed in the Computer System Fig. 4 shows an example of the flow of processing executed in the computer system 210. Each step shown below is executed by the computer system 210 (particularly, the processor unit 212 of the computer system 210). Each step shown in Fig. 4 will be described in detail below.

Step S401: An input from a user is received. The input from the user is received, for example, from the user device _220-1 . The input from the user includes, for example, answers entered by the user to a number of questions. More specifically, the input from the user includes, for example, information about the user's eating and drinking habits. The input from the user includes, for example, information that can identify the user's interest in wine. This process corresponds to the user operations described with reference to FIG. 1A.

Step S402: Evaluation points for the taste types of the multiple wines are calculated. The evaluation points for each taste type are calculated, for example, based on a correspondence table showing the correspondence between the option selected for each of the multiple questions and the score for each taste type. An example of a correspondence table between the option selected for each of the multiple questions and the score for each taste type is Table 1 below. Such a correspondence table is stored, for example, in the database unit 240. The evaluation point for each taste type may be, for example, a score obtained as a result of adding up the scores for each taste type. Alternatively, the evaluation point for each taste type may be calculated and/or determined, for example, based on a correspondence table showing the correspondence between the score obtained by adding up all the scores for each taste type and the evaluation point for each taste type.

In Table 1, "(1) +2" indicates that +2 points are added when the first option is selected. In addition, "W01", "W02", "R01", "R02", and "S01" are examples of taste type names and/or identifiers. Therefore, for example, when the first option is selected by the user in question 1, +2 points are added as the evaluation point of the taste type "W01", and +1 point is added as the evaluation point of the taste type "W02". In addition, for example, when the second option is selected by the user in question 1, +1 point is added as the evaluation point of the taste type "R01", and +2 points are added as the evaluation point of the taste type "R02". In addition, for example, when the third option is selected by the user in question 1, +1 point is added as the evaluation point of the taste type "S01". In addition, as shown in the case where the first option is selected by the user in question 2, the points added as the evaluation point of each taste type may be negative. Furthermore, as shown when the user selects either option 1 or 2 in question 3, the number of points added to the evaluation score for each flavor type may differ depending on the option selected.

In the above embodiment, an example was described in which the evaluation score for each taste type was calculated based on a correspondence table, but the present invention is not limited to this. For example, the evaluation score for each taste type of each wine may be calculated based on a predetermined formula in which the value corresponding to the option selected for each question is used as a variable.

In the above embodiment, the evaluation score for each taste type is calculated using an additive method, but the present invention is not limited to this. The evaluation score for each taste type may be calculated using a subtractive or multiplicative method. The evaluation score for each taste type may also be calculated based on a weighting corresponding to the option selected for a particular question.

Step S403: A score for each of the multiple wines is calculated. The score for each wine is calculated, for example, based on the evaluation score for each taste type calculated in step S402. The score for each wine can be calculated, for example, based on a predetermined formula that includes the evaluation score for each wine's taste type as a variable. The predetermined formula that includes the evaluation score for each wine's taste type as a variable can be expressed as A+P, where A is a constant and P is the evaluation score for the wine's taste type. For example, the score for wine X can be calculated as the sum of a constant and the evaluation score for the taste type to which wine X belongs, calculated in step S402. Alternatively, the predetermined formula that includes the evaluation score for each wine's taste type as a variable can be expressed as A×P (i.e., the score for each wine can be a constant multiple of the evaluation score for each wine's taste type).

Step S404: The user's wine preferences are identified. The user's wine preferences are identified, for example, based on the scores of each of a plurality of wines. For example, the processor unit 212 of the computer system 210 may identify wines with scores equal to or above a threshold as wines preferred by the user.

The user's preferences are reflected in the user input received in step S401, and the score for each wine is calculated as described above and based on the user input received in step S401, so that wines with scores above a threshold can be identified as wines that suit the user's tastes (i.e., wines that the user likes).

Step S405: The user's wine preferences are notified to the user. This can be achieved, for example, by transmitting information indicating the user's wine preferences to the user device _220. 1. This process corresponds to the screen display described with reference to FIG. 1B.

Figure 5 shows another example of the flow of processing executed in computer system 210. Each step shown below is executed by computer system 210 (particularly, processor unit 212 of computer system 210). Each step shown in Figure 5 will be described in detail below.

Step S501: Information indicating the evaluation score of wine X drunk by the user is received. The information indicating the evaluation score of wine X drunk by the user may include information for identifying wine X (wine ID). This process corresponds to the user operation described with reference to FIG. 1C.

Step S502: The evaluation points of each of the multiple attributes of wine X drunk by the user are updated. This process is performed based on the evaluation point of wine X received in step S501. This process is performed, for example, based on the evaluation point of wine X received in step S501 and the evaluation points of one or more wines previously evaluated by the user. In particular, the process of updating the evaluation point of the taste type to which wine X belongs is performed, for example, based on the evaluation point of wine X received in step S501 and the evaluation points of the taste types of multiple wines calculated in step S402 of FIG. 4. Alternatively, the process of updating the evaluation point of the taste type to which wine X belongs is performed, for example, based on the evaluation point of wine X received in step S501, the evaluation points of the taste types of multiple wines calculated in step S402 of FIG. 4, and the evaluation points of one or more wines previously evaluated by the user. The updated evaluation points of the taste type, the updated evaluation points of the origin, and the updated evaluation points of the variety are stored, for example, in the user database unit 242.

For example, if the attributes of wine X consist of the taste type "refreshing fruity" identified by "W01", the origin "New Zealand", and the variety "Cabernet Sauvignon", the evaluation score for the taste type "refreshing fruity", the evaluation score for the origin "New Zealand", and the evaluation score for the variety "Cabernet Sauvignon" are updated.

For example, if the user has not previously evaluated wines, the evaluation score for the taste type "refreshing fruity" is updated by taking the average of a constant multiple (e.g., 2x or 3x) of the evaluation score for the taste type "refreshing fruity" calculated in step S402 of FIG. 4 and the evaluation score for wine X received in step S501, and this average is set as the updated evaluation score for the taste type "refreshing fruity". As an example of calculating the evaluation score for a taste type, if the evaluation score for the taste type "refreshing fruity" calculated in step S402 of FIG. 4 is 3.5 points and the evaluation score for wine X received in step S501 is 3.0 points, the updated evaluation score for the taste type "refreshing fruity" is (3.5 x 2 + 3.0) ÷ (2 + 1) = 3.33 points.

If the user has previously evaluated wines, the evaluation score for the “refreshing fruity” taste type is updated by averaging a constant multiple (e.g., two or three times) of the evaluation score for the “refreshing fruity” taste type calculated in step S402 of FIG. 4, the evaluation score for wine X received in step S501, and the evaluation scores for one or more wines of the “refreshing fruity” taste type that the user has previously evaluated, and this average value becomes the updated evaluation score for the “refreshing fruity” taste type. As an example of calculating the evaluation score for a taste type, if the evaluation score for the taste type "refreshing fruity" calculated in step S402 in FIG. 4 is 3.5 points, the evaluation score for wine X of the taste type "refreshing fruity" received in step S501 is 3.0 points, and the user has previously rated wines _Y1 to _Y4 belonging to the taste type "refreshing fruity" as 4.0 points, 4.5 points, 4.0 points, and 4.0 points, respectively, the updated evaluation score for the taste type "refreshing fruity" is (3.5 x 2 + 3.0 + 4.0 + 4.5 + 4.0 + 4.0) / (2 + 1 + 4) = 3.79 points.

By updating the evaluation score for the "refreshing fruity" taste type in this way, when the cumulative number of wines previously evaluated is small, the evaluation score for the "refreshing fruity" taste type calculated in step S402 of FIG. 4 is more significantly reflected as an evaluation score for the "refreshing fruity" taste type, and the more wines evaluated, the more the evaluation scores for wines of the "refreshing fruity" taste type that the user has drunk are more significantly reflected as an evaluation score for the "refreshing fruity" taste type.

Also, for example, the evaluation score for the origin "Made in New Zealand" is updated by taking the average of the evaluation score for wine X received in step S501 and the evaluation scores for one or more wines of the origin "Made in New Zealand" previously rated by the user, and the average is set as the updated evaluation score for the origin "Made in New Zealand." As an example of calculating the evaluation score for a place of origin, if the evaluation score for wine X of the origin "Made in New Zealand" received in step S501 is 3.0 points, and the user previously rated wines _Z1 to _Z3 of the origin "Made in New Zealand" as 2.5 points, 2.0 points, and 3.5 points, respectively, the updated evaluation score for the origin "Made in New Zealand" is (3.0 + 2.5 + 2.0 + 3.5) / (1 + 3) = 2.75 points.

Also, for example, the evaluation score of the variety "Cabernet Sauvignon" is updated by taking the average of the evaluation score of wine X received in step S501 and the evaluation scores of one or more wines of the variety "Cabernet Sauvignon" previously evaluated by the user, and the average is set as the updated evaluation score of the variety "Cabernet Sauvignon". As an example of the calculation of the evaluation score of the origin, if the evaluation score of wine X of the variety "Cabernet Sauvignon" received in step S501 is 3.0 points, and the user previously evaluated wines W ₁ to W ₅ of the variety "Cabernet Sauvignon" as 4.0 points, 4.0 points, 3.5 points, 5.0 points, and 4.5 points, respectively, the updated evaluation score of the variety "Cabernet Sauvignon" is (3.0 + 4.0 + 4.0 + 3.5 + 5.0 + 4.5) / (1 + 5) = 4.0 points.

In the above embodiment, an example was described in which the evaluation score of each attribute is updated by taking the average value, but the present invention is not limited to this. For example, the evaluation score of each attribute may be updated using a point-adding method, a point-deducting method, a combination of a point-adding method and a point-deducting method, or a method using weighting.

After step S502, at any timing before steps S505 and S506, the coefficient Q corresponding to the updated evaluation score of the place of origin may be identified as the coefficient associated with the place of origin by the computer system 210 (particularly, the processor unit 212 of the computer system 210). That is, by updating the evaluation score of the place of origin, the coefficient Q associated with the place of origin is also updated.

The coefficient Q associated with the place of origin may be calculated using a predetermined formula including the updated evaluation score of the place of origin as a variable (for example, the coefficient Q associated with the place of origin "Made in New Zealand" may be calculated using a predetermined formula including the updated evaluation score of the place of origin "Made in New Zealand" as a variable). Alternatively, the coefficient Q associated with the place of origin may be determined based on a correspondence table showing the correspondence between the updated evaluation score of the place of origin and the coefficient associated with the place of origin. An example of such a correspondence table is Table 2 below.

At any time after step S502 and before steps S505 and S506, the coefficient R corresponding to the updated evaluation score of the variety may be identified by the computer system 210 (particularly, the processor unit 212 of the computer system 210) as the coefficient associated with the variety. That is, by updating the evaluation score of the variety, the coefficient R associated with the variety is also updated.

The coefficient R associated with the variety may be calculated using a predetermined formula that includes the updated evaluation score of the variety as a variable (for example, the coefficient R associated with the variety "Cabernet Sauvignon" may be calculated using a predetermined formula that includes the updated evaluation score of the variety "Cabernet Sauvignon" as a variable). Alternatively, the coefficient R associated with the variety may be determined based on a correspondence table that indicates the correspondence between the updated evaluation score of the variety and the coefficient associated with the variety. An example of such a correspondence table is Table 3 below.

Step S503: One or more wines are identified that have attributes that at least partially match multiple attributes of the wine drunk by the user. This process is performed, for example, by referring to the wine database unit 241.

For example, if the attributes of wine X drunk by a user consist of a taste type "refreshing fruity" identified by "W01", a region of origin "New Zealand", and a variety "Cabernet Sauvignon", one or more wines belonging to the taste type "refreshing fruity", one or more wines of the region of origin "New Zealand", and one or more wines of the variety "Cabernet Sauvignon" are identified.

Step S504: It is determined whether the cumulative number of bottles of wine drunk by the user is less than a threshold value. This process is executed, for example, by referring to the user database unit 242 and based on information indicating the cumulative number of bottles of wine drunk by the user. The threshold value includes, for example, but is not limited to, 5 bottles, 10 bottles, or 20 bottles. If the determination result is "Yes", the process proceeds to step S505, and if the determination result is "No", the process proceeds to step S506.

Step S505: Using a predetermined first formula, the score allocation of the wine identified in step S503 is updated. The predetermined first formula includes the updated evaluation scores of each of the multiple attributes of the multiple wines as variables. The predetermined first formula can be expressed, for example, as A+P×Q×R, where A is a constant, P is the evaluation score of the taste type, Q is a coefficient associated with the origin, and R is a coefficient associated with the variety. However, at least one of P, Q, and R is the evaluation score updated in step S502.

For example, if the evaluation score for the taste type "refreshing fruity", the evaluation score for the origin "New Zealand", and the evaluation score for the variety "Cabernet Sauvignon" are updated in step S502, the score allocation for wine U (taste type "refreshing fruity", evaluation score for the origin "New Zealand", and variety "Pinot Noir") is calculated using a predetermined first formula based on the updated evaluation score P for the taste type "refreshing fruity", the coefficient Q corresponding to the updated evaluation score for the origin "New Zealand", and the coefficient R corresponding to the evaluation score for the variety "Pinot Noir".

Step S506: Using a predetermined second formula, the score of the wine identified in step S503 is updated. The predetermined second formula includes the updated evaluation scores of each of the multiple attributes of the multiple wines as variables. The predetermined second formula is different from the predetermined first formula. The predetermined second formula may be expressed, for example, as B + (P x Q x R - S) x standard deviation x C, where B and C are constants, P is the evaluation score of the taste type, Q is a coefficient associated with the origin, R is a coefficient associated with the variety, and S is a variable. However, at least one of P, Q, and R is the evaluation score updated in step S502. The variable S may be, for example, the average value of the evaluation score of wine X received in step S501 and the evaluation scores of all wines previously evaluated by the user. Alternatively, the variable S may be, for example, a value obtained by multiplying the average value of the evaluation score of wine X received in step S501 and the evaluation scores of all wines previously evaluated by the user by a coefficient associated with all origins and a coefficient associated with all varieties.

For example, if the evaluation score for the taste type "refreshing fruity", the evaluation score for the origin "New Zealand", and the evaluation score for the variety "Cabernet Sauvignon" are updated in step S502, the score allocation for wine V (taste type "pure fruity", evaluation score for the origin "New Zealand", and variety "Pinot Noir") is calculated using a predetermined second formula based on the evaluation score P for the taste type "pure fruity", the coefficient Q corresponding to the updated evaluation score for the origin "New Zealand", and the coefficient R corresponding to the evaluation score for the variety "Pinot Noir".

In this way, the method of updating the wine score may be changed depending on the cumulative number of wines the user has drunk. This allows the wine score to be updated more simply using a predetermined first formula when the cumulative number of wines previously rated is small, and the more wines rated above the threshold, the more complex the wine score can be updated using a predetermined second formula.

Step S507: The user's updated wine preferences are identified. The user's wine preferences are identified, for example, based on the updated and non-updated scores of multiple wines. For example, the processor unit 212 of the computer system 210 may identify wines that have a score equal to or above a threshold among the updated and non-updated scores of multiple wines as wines preferred by the user.

The evaluation scores of the wines drunk by the user received in step S501 reflect the user's preferences, and the scores of each wine are updated based on the evaluation scores of the wines drunk by the user received in step S501, as described above, so that wines with scores above a threshold can be identified as wines that suit the user's tastes (i.e., wines that the user likes).

Step S508: The user is notified of the user's updated wine preferences. This may be accomplished, for example, by transmitting information indicating the user's updated wine preferences to the user device _220-1 .

In the embodiment shown in FIG. 5, an example is described in which the method of updating the wine score is changed depending on the cumulative number of bottles of wine drunk by the user, but the present invention is not limited to this. The update of the wine score may be calculated using, for example, a single predetermined formula.

In the embodiment shown in FIG. 4 and FIG. 5, an example has been described in which the processing of each step shown in FIG. 4 and FIG. 5 is realized by the processor executing a program stored in the memory, but the present invention is not limited to this. At least some of the processing of each step shown in FIG. 4 and FIG. 5 may be realized by a hardware configuration such as a control circuit.

As described above, the present invention has been illustrated using a preferred embodiment of the present invention, but the present invention should not be interpreted as being limited to this embodiment. It is understood that the scope of the present invention should be interpreted only by the claims. It is understood that a person skilled in the art can implement an equivalent scope based on the description of the specific preferred embodiment of the present invention and common technical knowledge from the description of the present invention.

The present invention is useful for providing a system for presenting a user's wine preferences, and a program executed in the system.
