Alternative-ingredient Recommendation Based on Co-occurrence Relation on Recipe Database

This paper proposes a recommendation method of alternative-ingredients based on co-occurrence relation on recipe database. Currently, dishes are often cooked with reference to recipes on Website. Convenience to access so many and varied recipes encourages beginners to cook. Recipe on Website list ingredients used for a dish.
