Electronic Map POI Filtering by Time Period Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic map systems present outdated or unverified Point of Interest (POI) information, burdening users with the need to verify data reliability, as they often display incorrect or outdated locations of shops and other POIs.
Innovation Solution
A system and method for presenting POI information in an electronic map that includes an interface module for receiving search queries and time period conditions, a storage unit for verified POI data across multiple time periods, and a processing module to filter and display only verified POIs based on user input, ensuring accurate and up-to-date information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electronic map systems present all searched POI information, then the quantity of information is increased, but the reliability of the information deteriorates due to outdated or incorrect data
Solution Approach 1:
The system performs preliminary verification of POI information before presentation to users. A verification module checks POI data against multiple sources and time periods in advance, marking verified POIs with verification status and timestamps. This preliminary action ensures that only reliable information is presented, resolving the contradiction between information quantity and reliability.
Solution Approach 2:
The patent introduces a verification module as an intermediary between the POI database and the user interface. This module acts as a mediator that filters and validates POI information, adding verification status and time period metadata. The intermediary ensures that unreliable or outdated information does not reach the user, while maintaining access to comprehensive POI data through the verification layer.
2Reliability
If users manually verify POI information through multiple sources, then the reliability of information is improved, but the time and effort required is increased
Solution Approach 1:
The system implements self-service verification where the POI information automatically verifies itself against multiple data sources and time periods without user intervention. The verification module autonomously checks data consistency, marks verification status, and timestamps the information. Users simply access pre-verified POI data, eliminating the time and effort they would otherwise spend on manual verification while maintaining high reliability.
3Measurement precision
If the system stores and processes POI data from multiple time periods, then the accuracy of time-specific information is improved, but the device complexity is increased
Solution Approach 1:
The patent segments POI data by time periods, organizing information into distinct temporal categories. Each POI entry includes timestamp metadata and verification status markers that divide the data structure into manageable segments. This segmentation allows the system to efficiently query and retrieve time-specific information without processing the entire dataset, reducing computational complexity while maintaining precise time-specific accuracy.
Data Source
AI summary
A map system for presenting Point of Interest (POI) information is provided with an interface module, a storage unit, and a processing module. The interface module is coupled to a display device and provides an operation interface for receiving a search query and a condition of time period. The storage unit stores a plurality of POIs data and verified data of the POIs each corresponding to a respective one of different time periods. The processing module filters the POIs and the verified data according to the search query and the condition of time period to generate an electronic map, and displays the electronic map to present the filtered POIs via the interface module and the display device.
