Recognition Dictionary Version Selection for Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recognition accuracy is compromised when a specific bias, such as writing habit or fading, is present in the learning data of the latest recognition dictionary version, leading to reduced accuracy for documents with similar biases, unless an older version is used.
Innovation Solution
An information processing apparatus that selects between applying the latest recognition dictionary version or a version with the highest correct answer rate, derived from recognition and confirmation results across multiple documents, to optimize recognition accuracy.

Engineering Contradiction Analysis
1Measurement precision
If the latest version of recognition dictionary is used to increase recognition accuracy, then recognition accuracy is improved for documents with similar biases, but recognition accuracy deteriorates when specific bias (writing habit or fading) is frequently generated in the learning data
Solution Approach 1:
The system changes the version parameter of the recognition dictionary to optimize recognition accuracy. Instead of always using the latest version, the system selects from multiple versions (including latest and previous versions) based on which version performs better for the given document, thereby adapting the parameter (version number) to resolve the contradiction between improving accuracy through updates and maintaining reliability when biases are present
Solution Approach 2:
The system dynamically selects the recognition dictionary version based on the specific document being processed. Rather than statically using the latest version, the system evaluates and switches between different versions (latest version or previous versions) to adapt to varying document characteristics and bias patterns, making the version selection dynamic rather than fixed

AI summary
An information processing apparatus includes a selection unit that, when a target document is recognized, selects a first mode in which a latest version of a recognition dictionary is applied, or a second mode in which a version of the recognition dictionary is applied, the version of the recognition dictionary having a highest correct answer rate among plural versions different from the latest version, the correct answer rate being obtained from a recognition result and a confirmation or correction result of each of plural documents.
