Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in narrowing the retrieval range of documents without requiring skilled techniques to revise search keywords or expressions, leading to lengthy and inefficient document extraction processes.
Innovation Solution
A document retrieving apparatus that allows users to designate areas on a two-dimensional map, combining query vectors of documents within the area to extract relevant documents through a search engine, eliminating the need for complex keyword revisions and enabling quick retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user revises search keywords or expressions to narrow retrieval range, then retrieval precision is improved, but operation complexity increases and requires skilled techniques
Solution Approach 1:
The patent introduces a two-dimensional map as an intermediary visual tool between the user and the document retrieval system. Users can directly interact with the map by designating areas, and the system automatically translates these visual selections into precise document retrieval operations, eliminating the need for users to manually construct complex search expressions.
Solution Approach 2:
The patent replaces the mechanical process of manually revising and constructing search keywords with an automated system that processes visual area designations on a two-dimensional map. The system automatically extracts documents based on the designated map areas, substituting user manual keyword construction with automated computational processing.
2Measurement precision
If a user manually creates appropriate search expressions to narrow retrieval range, then retrieval precision is improved, but time consumption increases
Solution Approach 1:
The patent performs preliminary action by pre-computing and displaying a two-dimensional map that visually organizes documents before the user needs to retrieve them. The map is prepared in advance with documents positioned according to their characteristics, allowing users to immediately begin area designation without waiting for system processing or manual query formulation.
Solution Approach 2:
The patent substitutes the time-consuming manual process of creating and refining search expressions with an automated system that processes visual area designations on a pre-computed two-dimensional map. The system automatically extracts and returns documents based on the user's visual selection, dramatically reducing the time required compared to manual keyword construction.
3Quantity of substance
If the system displays all retrieved documents without visual organization, then completeness is maintained, but user ability to quickly identify target documents deteriorates
Solution Approach 1:
The patent applies dimensionality change by organizing documents in a two-dimensional space rather than presenting them in a traditional one-dimensional list. The two-dimensional map provides additional spatial dimensions for document organization, allowing users to visually perceive relationships and quickly identify target documents through area designation on the map.
Solution Approach 2:
The patent utilizes visual differentiation through color and spatial positioning on the two-dimensional map to highlight document characteristics and relationships. By varying visual attributes in the map representation, users can quickly identify and distinguish relevant documents from irrelevant ones, enhancing their ability to rapidly locate target documents while maintaining completeness.

AI summary
A document retrieving apparatus can retrieve a target document and output the retrieved target documents according to ranking when a retrieval keyword or retrieval expression is input. However, it requires a skilful technique to narrow a retrieval range since an appropriate retrieval keyword or retrieval expression needs to be created. A document retrieving apparatus of the present invention reads out and compiles a document list included in a designated area when a user designates an area of a document to be read on a two-dimensional map. When the user designates an area of a document to be read on the two-dimensional map, the document retrieving apparatus of the present invention combines query vectors of a plurality of documents included in a designated area and extracts documents based on a combined query vector.
