Abstract In titles of recipes shared over Rakuten recipe, various modiﬁers such as ʠ easy, ʡʠ healthy, ʡ andʠ kid-friendly ʡ are often used for representing the recipes’ characteristics. Although the same modiﬁer is used insome recipes’ titles, its concepts would have more variety. In this paper, we propose a method to extract naming
concepts of recipes. Speciﬁcally, we obtain typical ingredients and cookwares by summarizing recipes of a cooking
and extract diﬀerences in terms of addition and deletion by comparing the typical elements with those of each recipeof the same cooking. Then, we extract naming concepts of a modiﬁer by representing the recipes as feature patterns
based on the diﬀerences and classifying them based on the patterns.
