Electronic Map Event Search Using POI Attribute Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic map retrieval services are limited to address information only, failing to satisfy requirements for event location retrieval and providing inaccurate results due to expired event information.
Innovation Solution
A search method and apparatus for electronic maps that determine if input search information is event-type, extract relevant event content, and associate it with point of interest (POI) attribute information, filtering out non-event data and removing expired information to provide accurate event-related location information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic map provides only address information retrieval, then the system complexity remains low, but the search functionality is limited and cannot satisfy event location retrieval requirements
Solution Approach 1:
The electronic map system is enhanced to perform multiple types of search operations including traditional address information retrieval and new event-type search operations. The search module is designed to handle both simple address queries and complex event location queries, allowing the same system to serve diverse user needs without requiring separate specialized systems for each function.
Solution Approach 2:
The system performs preliminary actions by pre-processing and storing event attribute information along with POI data in the electronic map database. Event information including time, location, and descriptive attributes is extracted and associated with relevant POIs before user queries are received. This preliminary preparation enables the system to quickly and accurately retrieve event location information when users search for events, without requiring complex real-time processing during the actual search operation.
2Adaptability or versatility
If the electronic map includes event-type search functionality, then the search forms are enriched, but the accuracy of search results may be affected by expired event information
Solution Approach 1:
The system performs preliminary actions by pre-processing and storing event attribute information along with POI data in the electronic map database. Event information including time, location, and descriptive attributes is extracted and associated with relevant POIs before user queries are received. This preliminary preparation enables the system to quickly and accurately retrieve event location information when users search for events, without requiring complex real-time processing during the actual search operation.
Solution Approach 2:
The search module incorporates feedback mechanisms to verify the relevance and validity of retrieved event information. When users search for events, the system not only retrieves based on pre-stored data but also incorporates feedback loops to confirm the information is current and accurate, filtering out expired or irrelevant event data to maintain high search result accuracy.
3Adaptability or versatility
If the electronic map stores and processes event information, then event location retrieval is enabled, but the data processing complexity increases
Solution Approach 1:
The data processing system is segmented into distinct functional modules: event information extraction module, POI association module, search query processing module, and result retrieval module. Each module handles specific tasks independently, such as extracting event attributes from raw data, associating events with POIs, processing user queries, and retrieving results. This segmentation reduces overall processing complexity by dividing the complex data processing task into smaller, manageable sub-tasks that can be executed efficiently in parallel.
Solution Approach 2:
The system performs preliminary actions by pre-processing and storing event attribute information along with POI data in the electronic map database. Event information including time, location, and descriptive attributes is extracted and associated with relevant POIs before user queries are received. This preliminary preparation enables the system to quickly and accurately retrieve event location information when users search for events, without requiring complex real-time processing during the actual search operation.

AI summary
Provided are a search method and apparatus for an electronic map, a device and a medium that relate to the field of electronic map technology. The implementation solution includes determining whether target search information input by a user is event-type search information; in response to the target search information being the event-type search information, extracting target event content from the target search information; and determining a target POI based on the target event content and event attribute information associated with a POI in the electronic map and using the target POI as a search result. The event attribute information includes at least event content.
