Search Result Deduplication via Category Subcategory Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces for searching items often display duplicate results and items from the same category repeatedly, wasting screen space and failing to provide an accurate depiction of the variety of available brands or subcategories.
Innovation Solution
Implementing a system that generates category-specific search results by removing duplicates from original search results and limiting the display to unique items from different subcategories, with the duplication removal service comparing items in original and categorical search results to append duplicates to the end of the categorical results and the category summary generator ensuring only one instance of each subcategory is displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If duplicate items are displayed in search results, then the quantity of search results is increased, but the screen space is wasted and user interface efficiency is reduced
Solution Approach 1:
The patent extracts duplicate items from the search results by comparing each item against previously displayed items using a data structure (e.g., HashSet) to identify and remove duplicates, thereby displaying only unique items and improving screen space utilization and user interface efficiency
Solution Approach 2:
The patent changes the parameter of item uniqueness by introducing a comparison mechanism that evaluates items based on their identifiers or attributes, filtering out duplicates while preserving diverse items, thus optimizing the balance between result quantity and display efficiency
2Quantity of substance
If multiple items from the same category are displayed, then the variety of search results is increased, but the representation of brand diversity is reduced
Solution Approach 1:
The patent segments the search results by category and applies different display strategies to each category, such as limiting the number of items per brand or category while ensuring representation from multiple brands, thereby maintaining brand diversity information while still providing variety in search results
Solution Approach 2:
The patent applies local quality by treating different categories differently in the display logic, ensuring that each category contributes to brand diversity representation according to its specific characteristics, thus preventing loss of brand diversity information while maintaining overall result variety

AI summary
Disclosed are various embodiments for generating a de-duplicated and subcategory summary search results in response to a search query. A set of original search results and a set of categorical search results may be obtained in response to a search query. The original search results may be relevant to the search query while the categorical search results may be relevant to the search query and a category. The items in the categorical search results may be associated with various subcategories. The duplicate items in the categorical search results and at least a portion of the original search results may be removed from the categorical search results. The repeated instances of each of the subcategories may be removed from the categorical search results.
