Search Result Card Screening for Accurate User Demand Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately identify user demands, leading to mismatched information cards that degrade the user's search experience.
Innovation Solution
A method and apparatus that identify user demands through terminal input, acquire relevant information cards, perform feature-based screening, and send targeted information cards and search results to enhance accuracy and richness of displayed information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cards are issued based on identified user demand, then information delivery is achieved, but if user demand is not identified accurately, the card issued does not meet user demand, damaging search experience
Solution Approach 1:
The system performs preliminary actions by pre-defining multiple categories of preset information sets and pre-screening information cards before user search. When a user performs a search, the system quickly matches the search query against the pre-organized categories and selects from pre-screened cards, rather than performing real-time comprehensive screening. This preliminary organization and pre-screening significantly improves the speed and accuracy of user demand identification while ensuring card relevance.
2Quantity of substance
If comprehensive information cards are provided to meet diverse user needs, then information richness is improved, but the complexity of selecting and screening appropriate cards increases
Solution Approach 1:
The system segments the comprehensive information set into multiple distinct categories (e.g., news, entertainment, sports, finance) with each category containing specialized preset information sets. This segmentation allows the system to present diverse and rich information according to user interests without overwhelming complexity, as each category is independently managed and screened. The segmentation structure makes it easier to select and screen appropriate cards by narrowing down the search scope within relevant categories.
3Measurement precision
If real-time screening of information cards is performed, then accuracy is improved, but processing time and system response speed decrease
Solution Approach 1:
The system performs preliminary screening and categorization of information cards before user queries arrive. By pre-organizing information into categories and pre-screening cards against predefined criteria, the system eliminates the need for real-time comprehensive screening. When a user searches, the system quickly retrieves pre-screened cards from relevant categories, significantly improving response speed while maintaining high accuracy through the pre-established screening criteria.

AI summary
Embodiments of the present application provides a method and apparatus for sending information. A specific implementation of the method includes: identifying search information input through a terminal by a user, to obtain the user's demand; acquiring, based on the user's demand, at least one information card from at least one category of preset information set, where the information set includes information and information cards used to describe the information; performing information search based on the search information, to obtain a search result; screening, based on feature information of the search result, the at least one information card to obtain a target information card; and sending to-be-displayed information to the terminal based on the target information card and the search result.
