Location-Based Keyword Extraction for Mobile Search Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information retrieval systems for mobile devices are cumbersome due to the difficulty of text input on small keypads, leading to a high burden on users when searching for information, and they struggle with handling large amounts of information content and providing sufficient word-of-mouth information, which often results in short and insufficient responses.
Innovation Solution
An information providing apparatus that extracts keywords from user-generated content associated with location and time information, uses a keyword database to rank relevant information based on proximity and relevance, and sends search requests to a search server to provide optimal information to mobile devices, simplifying user operations and improving information accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually input search queries on mobile devices, then search functionality is available, but user burden increases due to difficulty of text input on small keypads
Solution Approach 1:
The system automatically performs information retrieval without requiring manual user input. The mobile device autonomously transmits location information to the information providing apparatus, which then automatically searches and retrieves relevant information based on the user's current location, eliminating the need for manual typing or complex input operations.
Solution Approach 2:
The information providing apparatus acts as an intermediary between the user's location data and the search server. It receives location information from the mobile device, automatically generates appropriate search queries, and retrieves information from external servers, thereby mediating the complex search process and presenting simplified results to the user.
2Loss of information
If comprehensive information content is stored and processed, then information completeness improves, but system complexity and processing burden increase
Solution Approach 1:
The system extracts only the essential location information from the mobile device and transmits it to the information providing apparatus. External servers are utilized to store and process comprehensive information content, while the mobile device maintains a lightweight implementation, thereby extracting the core functionality from the complex system.
Solution Approach 2:
The system shifts the information storage and processing burden to an external dimension by utilizing remote servers. The information providing apparatus acts as an intermediary that leverages external computational resources, allowing comprehensive information handling without increasing the complexity of the mobile device or local system.
3Ease of operation
If location-based information retrieval is automated, then ease of use improves, but accuracy of information matching may deteriorate without proper keyword extraction
Solution Approach 1:
The information providing apparatus performs preliminary processing of location information by automatically extracting relevant keywords and generating optimized search queries before transmitting requests to external servers. This preliminary action ensures that the automated system maintains high matching accuracy by pre-processing data in an intelligent manner.
Solution Approach 2:
The system implements feedback mechanisms where search results are analyzed and refined. The information providing apparatus receives results from external servers, processes them through keyword analysis, and can adjust subsequent searches based on the quality and relevance of returned information, thereby maintaining accuracy through iterative refinement.

AI summary
An information providing apparatus includes: a communication unit to receive transmitted information containing first location information associated with a first communication apparatus; a registering unit to extract, from the transmitted information, one or more keywords and the first location information, and to register the first location information and the one or more keywords in a keyword database; a request interface to receive a request for information from a second communication apparatus and a second location information associated with the second communication apparatus; an extractor to reference the keyword database and to extract one or more keywords based on the second location information; and a search requesting unit to output a search request containing the one or more keywords extracted by the extractor, wherein the search request is output to another computer that executes a search to provide information to the second communication apparatus.
