Context-Aware Character Recognition Verification Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Character recognition errors in image processing require manual confirmation and proofreading, which are time-consuming and burdensome for workers, despite existing UI methods that list and display similar character images for visual confirmation.
Innovation Solution
An information processing apparatus that extracts character strings and unit characters from document images, generates context information, and displays the extracted characters along with their context on a UI screen, facilitating efficient confirmation of character recognition results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual confirmation and proofreading operations are performed on extracted character results, then character recognition accuracy is improved, but time consumption and worker burden increase
Solution Approach 1:
Context information acts as an intermediary element between the character image and the user. By displaying context information (such as surrounding characters, word boundaries, or semantic information) alongside the character image, the system provides additional cues that help users verify recognition accuracy more quickly without requiring full manual proofreading of each character.
Solution Approach 2:
The system provides feedback to users by displaying context information that highlights potential recognition issues or confirms correct recognition. This feedback mechanism allows users to make faster judgment decisions about whether a character recognition is correct, reducing the time needed for manual confirmation while maintaining accuracy.
2Productivity
If character images are listed and displayed for visual confirmation, then confirmation efficiency is improved, but lack of contextual information limits verification accuracy
Solution Approach 1:
The system merges the character image display with context information display into a unified interface. Instead of showing only isolated character images, the invention combines them with surrounding textual context, making both the character image and its context simultaneously visible to the user, thereby enabling efficient verification without information loss.
3Ease of operation
If isolated character images are displayed for confirmation, then ease of visual checking is improved, but absence of context reduces verification reliability
Solution Approach 1:
The system adds another dimension to the display by incorporating context information alongside the character image. This dimensional expansion transforms the display from showing only isolated characters to showing characters within their contextual framework, enabling users to maintain easy visual checking while simultaneously improving verification reliability through additional contextual cues.

AI summary
An information processing apparatus includes: at least one memory that stores instructions; and at least one processor that executes the instructions to: extract a character string and a unit character included in the character string based on a result of character recognition processing on a document image; generate context information related to the unit character based on the extracted character string and attribute information indicating an attribute of the character string; and display the extracted unit character and the context information corresponding to the unit character on a UI screen.
