Reference Mark Display for 2D Map Search Intent Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 2D map-based information search technologies fail to accurately match user intent, as users often need to trial-and-error designate regions to find relevant documents, leading to inefficiencies and incorrect extractions.
Innovation Solution
A 2D map is generated with search targets plotted based on feature vectors, including a reference mark at the position corresponding to the user's input, allowing users to designate regions with precision and extract relevant information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a 2D map is displayed with search targets plotted based on feature vectors, then similar documents are efficiently extracted, but it is unknown which region to designate to match user search intention
Solution Approach 1:
The patent introduces a reference mark as an intermediary element that mediates between the user's search intention and the 2D map representation. The reference mark is positioned at the location corresponding to the user's input information on the 2D map, serving as a visual guide that helps users accurately designate regions that match their search intent, thereby resolving the contradiction between extraction efficiency and matching accuracy.
Solution Approach 2:
The patent performs preliminary action by pre-positioning the reference mark on the 2D map before the user designates a region. This advance placement of the reference mark at the location corresponding to the user's input information provides users with immediate visual guidance, eliminating the need for trial-and-error region designation and ensuring accurate search intention matching from the outset.
2Adaptability or versatility
If users designate regions on trial basis to extract documents, then search coverage is increased, but time consumption increases due to repeated searches
Solution Approach 1:
The reference mark acts as an intermediary that provides immediate visual feedback to users about where to designate regions on the 2D map. By showing the position corresponding to the user's input information, the reference mark enables users to perform accurate region designation in a single attempt, thereby maintaining comprehensive search coverage while eliminating time-wasting repeated searches.
3Measurement precision
If a reference mark is displayed at the position corresponding to user input information, then users can accurately designate desired regions, but device complexity increases
Solution Approach 1:
The patent applies segmentation by separating the reference mark function from the main 2D map display. The reference mark is positioned at the location corresponding to the user's input information and serves as a distinct visual indicator that guides region designation. This segmentation approach enhances region designation accuracy while minimizing system complexity by adding only a simple visual marker rather than complex processing mechanisms.

AI summary
Included is a reference mark display unit 13 that specifies search target feature vectors characterizing arbitrary input search targets or relevant element feature vectors characterizing arbitrary input relevant elements, and displays a predetermined reference mark at a corresponding position on a 2D map based on coordinate information based on the specified feature vectors. By displaying a 2D map in which a reference mark is indicated at a corresponding position specified from arbitrary input information rather than a 2D map in which a plurality of search targets is merely plotted on a 2D plane, it is possible to extract a search target by designating a desired region on the 2D map with reference to a position of the reference mark corresponding to the arbitrary input information.
