Device for presenting recipe and method for presenting recipe

A recipe presentation method comprising:

• receiving input for specifying a dish from a user;
• searching for a first recipe including preparation elements of (i) ingredients which are materials for the dish received in the receiving, (ii) intermediate ingredients which are processed from the ingredients and to be further processed before completion of the dish, each of the intermediate ingredients being identified by an ID for unique identification and having values respectively identifying an item of preparation, a process performed on the item of preparation, and a preceding preparation element, and (iii) a dish which indicates the dish received in the receiving as a dish to be served;
• calculating similarities between individual recipes for dishes and the first recipe retrieved in the searching;
• selecting, according to the similarities calculated in the calculating, a second recipe which is a recipe similar to the first recipe among the recipes for the dishes;
• and
• presenting a dish corresponding to the second recipe selected in the selecting,
• wherein the calculating includes calculating the similarity between the first recipe and each of the recipes for the dishes by obtaining a weighted sum of an ingredient similarity and a process similarity, the ingredient similarity indicating a total number of common ingredients between the first recipe and the recipe for the dish, and the process similarity indicating a total number of common intermediate ingredients between the first recipe and the recipe for the dish.

An integrated circuit comprising:

• a receiving unit configured to receive input for specifying a dish from a user;
• a search unit configured to search for a first recipe which indicates a recipe including preparation elements of (i) ingredients for the dish specified in the input received by the receiving unit, (ii) intermediate ingredients which are processed from the ingredients and to be further processed before completion of the dish, each of the intermediate ingredients being identified by an ID for unique identification and having values respectively identifying an item of preparation, a process performed on the item of preparation, and a preceding preparation element, and (iii) a dish which indicates the dish as a dish to be served;
• a similarity calculation unit configured to calculate similarities between individual recipes for dishes and the first recipe retrieved by the search unit;
• a selection unit configured to select, according to the similarities calculated by the similarity calculation unit, a second recipe which is a recipe similar to the first recipe among the recipes for the dishes;
• and
• a presentation unit configured to present a dish corresponding to the second recipe selected by the selection unit,
• wherein the similarity calculation unit is configured to calculate the similarity between the first recipe and each of the recipes for the dishes by obtaining a weighted sum of an ingredient similarity and a process similarity, the ingredient similarity indicating a total number of common ingredients between the first recipe and the recipe for the dish, and the process similarity indicating a total number of common intermediate ingredients between the first recipe and the recipe for the dish.
