Recipe Evaluation System Using Ingredient Position Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking recipe search systems display undesired recipes at the top of search results due to the inclusion of input keywords in dish names or ingredients, and struggle to appropriately showcase recipes related to specific ingredients, especially when seasonal ingredients are involved.
Innovation Solution
A cooking recipe information providing system that determines an evaluation value for each recipe based on the order of a given ingredient in the ingredient field, using a recipe extracting, evaluation value determining, and display data generating mechanism to prioritize recipes with higher ingredient relevance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cooking recipes are extracted based on keyword inclusion in dish names or ingredients, then the quantity of search results increases, but the relevance and accuracy of displayed recipes deteriorates
Solution Approach 1:
The patent changes the parameter of recipe evaluation from simple keyword presence to a weighted scoring system that considers multiple factors including ingredient position order, ingredient quantity, and recipe category. This transforms the search algorithm to prioritize recipes where the keyword ingredient plays a significant role, thereby improving relevance accuracy while maintaining result quantity
Solution Approach 2:
The patent segments the recipe evaluation into multiple independent components: ingredient position score, ingredient quantity score, recipe category score, and user preference score. Each component is calculated separately and then aggregated, allowing the system to maintain comprehensive search results while filtering for high-relevance recipes through the segmented evaluation criteria
2Productivity
If recipes including seasonal ingredients are prioritized for display, then the promotional effectiveness improves, but the search result relevance for other ingredients deteriorates
Solution Approach 1:
The patent implements a dynamic evaluation system where the weight of seasonal ingredient positioning can be adjusted based on time of year and promotional needs. The ingredient position score is calculated dynamically, allowing operators to temporarily increase the weight of seasonal ingredients during their peak periods while maintaining normal evaluation criteria for other times, thus balancing promotional effectiveness with overall search relevance
Solution Approach 2:
The patent applies different evaluation weights to different ingredients based on their characteristics. Seasonal ingredients can be assigned elevated weights during specific periods, while other ingredients maintain standard weights. This localized quality adjustment allows promotional priorities to be applied selectively without compromising the overall relevance accuracy for non-promotional ingredients

AI summary
A cooking recipe information providing device includes: a recipe extracting unit (16) for extracting a prescribed cooking recipe from a recipe information DB (14a) for storing cooking recipes; an evaluation value determining unit (18) for determining an evaluation value of the cooking recipe extracted by the recipe extracting unit (16) based on a place in order of a given ingredient in an ingredient field where ingredients of the cooking recipe are displayed; and a display data generating unit (19) for generating display data which indicates information of the cooking recipe based on the evaluation value determined by the evaluation value determining unit (18).
