Mobile Search String Segmentation for Location-Based Relevance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current search engines lack sophistication in finding relevant information, as they do not effectively utilize location-based searches to provide contextually relevant data within a predetermined distance from a user's location.
Innovation Solution
A mobile apparatus and method that obtain a string, identify a location associated with the string, perform a location-based search using independent expressions, and display relevant location-dependent data on a map, allowing for more precise and effective information retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional search engines are used to search the Internet, then a vast amount of information can be accessed, but it is difficult to find relevant information effectively
Solution Approach 1:
The search string is divided into multiple independent expressions, allowing the system to perform separate location-based searches for each expression. This segmentation enables more precise matching of search terms with location-dependent data, improving result relevance while reducing time to find information.
Solution Approach 2:
The patent introduces a spatial dimension to traditional text-based search by integrating location data with search queries. Search results are filtered and displayed based on geographic proximity to the user's location, adding a spatial filter that enhances relevance without significantly increasing search time.
2Measurement precision
If location-based search is performed with multiple independent expressions, then search precision is improved, but search complexity increases
Solution Approach 1:
The system segments the search process into distinct steps: obtaining the search string, identifying independent expressions, obtaining location data, performing location-based searches for each expression, and displaying results on a map. This segmentation manages complexity by breaking down the overall task into manageable, sequential operations.
Solution Approach 2:
The mobile apparatus performs multiple functions within a single integrated system: text processing to identify independent expressions, location services to obtain geographic data, search engine functionality to query location-dependent data, and map display to present results. This multi-functionality reduces the need for separate applications and simplifies the user experience.
Data Source
AI summary
A mobile apparatus, a computer program for a mobile apparatus, and a method in a mobile apparatus. A string is obtained. A location associated with the string is obtained. Then, a location-based search for location-dependent data is performed on the basis of the location and one or more independent expressions within the string such that the location-dependent data is relevant within a predetermined distance from the location. Finally, at least a part of the location-dependent data is displayed on a map.
