Information presenting method, information presenting system, and information presenting program

An information presenting system which presents a food product meeting a user's preference, comprising:

• a processor;
• an inputting unit configured to input into the information presenting system
• a first numerical value representing the amount of a first component of the food product having an effect on the taste of the food product that is preferred by the user, and a second numerical value representing the amount of a second component of the food product having an effect on the taste of the food product that is preferred by the user;
• the processor calculating a first feature quantity indicative of the user's preferred taste for the food product based on the first and second inputted values;
• a memory which stores a food product data base that stores a temporal change in a content of each of the first and second components for each of one or more food products;
• the processor calculating, from the food product data base, progress information indicative of a temporal change in a second feature quantity indicative of a feature of the taste of each of the food products, and extracting a food product for which a Euclidean distance between the first feature quantity and the progress information is equal to or less than a reference value;
• and a presenting unit which presents the extracted food product,
• wherein the food product data base stores a temporal change in a representative value of a content of each of the first and second components for each of the food products and stores a reference content of each of the first and second components for each of the food products, and
• wherein the processor refers to measurement information which associates, with respect to each of the food products, the shipping date with a measurement value of each of the components on the shipping date, correcting, with respect to each of the food products, a content stored in the food product data base on a basis of a difference between the reference content and the measurement value, and calculating the progress information using the corrected content.

A non-transitory computer-readable recording medium that records an information presenting program which causes a computer to function as an information presenting system that presents a food product meeting a user's preference, the computer functioning as:

• an inputting unit configured to input into the information presenting system
• a first numerical value representing the amount of a first component of the food product having an effect on the taste of the food product that is preferred by the user, and
• a second numerical value representing the amount of a second component of the food product having an effect on the taste of the food product that is preferred by the user;
• a feature quantity calculating unit which calculates a first feature quantity indicative of the user's preferred taste for the food product based on the first and second inputted values;
• a food product data base which stores a temporal change in a content of each of the first and second components for each of one or more food products;
• an extracting unit which calculates, from the food product data base, progress information indicative of a temporal change in a second feature quantity indicative of a feature of the taste of each of the food products, and extracts a food product for which a Euclidean distance between the first feature quantity and the progress information is equal to or less than a value;
• and a presenting unit which presents the extracted food product,
• wherein the food product data base stores a temporal change in a representative value of a content of each of the first and second components for each of the food products and stores a reference content of each of the first and second components for each of the food products, and wherein the computer also functions to
• refer to measurement information which associates, with respect to each of the food products, the shipping date with a measurement value of each of the components on the shipping date, correct, with respect to each of the food products, a content stored in the food product data base on a basis of a difference between the reference content and the measurement value, and calculate the progress information using the corrected content.

An information presenting method in an information presenting system which presents a food product meeting a user's preference, the method comprising:

• by a computer of the information presenting system,
• inputting a single user evaluation value for each of a plurality of different examples of the food product, representing the degree of the user's preference for each of the plurality of examples of the food product;
• displaying a point on an x-y graph for each of the plurality of different examples of the food product whose evaluation value is greater than a predetermined threshold, one axis of the x-y graph representing values of the amount of a first food-product component, and the other axis of the x-y graph representing values of the amount of a second food-product component;
• setting a closed curve passing through or including the displayed points, and generating and displaying a region surrounded by the closed curve as a user preference region for the food product;
• inputting by the user of a point on the graph in the user preference region, indicative of a preferred taste of the user with respect to the food product;
• calculating a first feature quantity indicative of a feature of a taste indicated by the inputted point;
• calculating, from a food product data base which stores a temporal change in a content of each of one or more components for each of one or more food products, progress information indicative of a temporal change in a second feature quantity indicative of a feature of the taste of each of the food products, and extracting a food product for which a Euclidean distance between the first feature quantity and the progress information is equal to or less than a reference value;
• and presenting the extracted food product,
• wherein the food product data base stores a temporal change in a representative value of a content of each of the first and second food-product components for each of the food products and stores a reference content of each of the first and second components for each of the food products, and wherein the method further comprises referring to measurement information which associates, with respect to each of the food products, the shipping date with a measurement value of each of the components on the shipping date, correcting, with respect to each of the food products, a content stored in the food product data base on a basis of a difference between the reference content and the measurement value, and calculating the progress information using the corrected content.
