Thereby, the acquiring unit 132 acquires each information of the user ID, the date and time, the item ID, the store ID, the item name, the raw material name, and the allergen ID for the food provided to the user. In addition, the acquisition unit 132 generates a history ID regarding the user's receipt of the food. The acquisition unit 132 writes each information of the user ID, history ID, date and time, item ID, store ID, item name, ingredient name, and allergen ID to the action history storage unit 125 .

(Regarding the estimation unit 133)
The estimation unit 133 performs processing for estimating the allergens of food allergies that the user has, based on the action history data. From the action history data stored in the action history storage unit 125, the estimation unit 133 obtains the number of actions having raw material information that matches the allergen information included in the allergen information storage unit 122 for each raw material. The estimation unit 133 estimates the allergen based on the frequency distribution for each raw material.

For each of the 27 raw materials shown in FIG. 4, the estimation unit 133 counts the number of times the food containing the raw material was purchased and the number of times the food containing the raw material was provided. The estimation unit 133 counts the number of actions for each of the 27 raw materials for each user.

Taking the action history data stored in the action history storage unit 125 shown in FIG. Count the number of times for each raw material. For example, the estimation unit 133 adds 1 to the number of actions for each of the raw materials “peanuts”, “cashew nuts” and “walnuts” based on the data with the history ID “00211”. Based on the data with the history ID “00215”, the estimation unit 133 adds 1 to the number of actions for each ingredient “wheat” and “soba”. The estimating unit 133 adds the number of actions for data of all history IDs. As a result, the estimation unit 133 obtains the number of times the user U01 performs actions having raw material information that matches the allergen information for each raw material.

FIG. 9 is a diagram illustrating an example of an information processing method according to the embodiment. FIG. 9 is a radar chart showing the results of obtaining the number of actions for each of the 27 raw materials for the user U01. In the radar chart, the axes of each item representing the raw material are arranged radially from the center, and the distribution of the number of times for each raw material is represented by connecting the values representing the number of times for each item. The center of the radar chart indicates that the number of occurrences is zero, and the farther from the center, the higher the number of occurrences.

The estimation unit 133 obtains in advance a standard distribution by averaging distributions for all users whose action history data are stored. The estimation unit 133 compares the distribution for the specific user whose allergen is to be estimated with the standard distribution, and determines whether the distribution for the specific user has a significant difference from the standard distribution. The estimation unit 133 may determine whether or not there is a significant difference by comparing the radar chart created for the specific user with a radar chart representing a standard distribution, or may determine whether or not there is a significant difference using another method. . If the distribution for the specific user has a significant difference from the standard distribution, and the distribution for the specific user has a raw material with a significantly lower number of actions than the standard distribution, the estimation unit 133 determines that the raw material is Presumed to be an allergen of the specific user. The estimation unit 133 can use any method for comparing the distribution for each user and the standard distribution. In this way, the estimation unit 133 estimates the user's allergen based on the distribution of the number of times for each raw material obtained from the action history data. The estimation unit 133 writes the allergen estimation result to the user information storage unit 126 . When there is no raw material that is estimated to be the user's allergen, the estimation unit 133 writes an estimation result to the effect that there is no raw material that is estimated to be the allergen in the user information storage unit 126 .

When the user U01 is the target of allergen estimation, the estimation unit 133 compares the distribution for the user U01 shown in FIG. Suppose we decide that there is a significant difference and that the count for "egg" is significantly lower than the standard distribution. In this case, the estimation unit 133 estimates "egg" as the allergen of the user U01. The estimating unit 133 writes information of the ingredient name of the allergen “egg” and the allergen ID “003” of the egg as “estimated allergen” of the user ID “U00001” in the user information storage unit 126 .

It is assumed that the estimation unit 133 estimates allergens for users for whom the number of actions indicated in the action history data has reached a sufficient number for allergen estimation. The estimation unit 133 may determine whether or not the number of all actions has reached a sufficient number, depending on whether or not the history ID of data representing the latest action is greater than a predetermined threshold. This enables the estimation unit 133 to accurately determine whether or not the user avoids foods containing specific raw materials.

(About presentation unit 134)
The presentation unit 134 presents various types of information including information on foods to the user. For example, when the user performs an operation to search for food on the user terminal 10, the presentation unit 134 notifies the user whose allergen has been estimated by the estimation unit 133 that the information about the food containing the estimated allergen is excluded. present the information provided. When presenting information about food to the user, the presentation unit 134 reads the information of the “estimated allergen” stored in the user information storage unit 126, thereby displaying the name of the ingredient estimated to be the user's allergen. get.

For the user U01 whose allergen is presumed to be “egg”, when the user U01 requests a food search, the presentation unit 134 excludes foods containing eggs as raw materials from the search results. Information on foods other than the foods that are available is presented to the user U01 as a search result. In this way, the information processing apparatus 100 can refrain from presenting information that will encourage purchase of foods that the user should refrain from consuming. The information processing apparatus 100 can provide services to users with food allergies while excluding information that is inappropriate to provide to the users. In addition, the information processing apparatus 100 can prevent users with food allergies from accidentally purchasing foods containing allergens.

The presentation unit 134 presents to the user search results in which foods containing allergens are excluded. You can present it to The display for calling attention is, for example, a mark indicating that the product contains an allergen. In this case, the information processing apparatus 100 can warn the user who has food allergies that the food contains ingredients that are presumed to be the user's allergens.
