Translation Device Term Substitution Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine translation devices face difficulties in accurately translating sentences containing unfamiliar words, often requiring extensive term registration and potentially affecting the translation of generic terms, leading to inaccurate translations.
Innovation Solution
A translation device that temporarily replaces specific terms with generic substitute terms during the translation process, then restores the original terms in the translated output, allowing for improved usability by registering only specific terms without their translations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the translation device registers translations for all specific terms in advance, then translation accuracy for those terms is improved, but the complexity of term registration and device configuration increases significantly
Solution Approach 1:
The system performs preliminary replacement of specific terms with substitute terms before the translation process begins. This allows the translation device to handle specific terms without requiring pre-registration of their translations, as the replacement occurs automatically based on pre-stored substitution rules.
Solution Approach 2:
The patent introduces substitute terms as intermediaries between specific terms and their translations. Instead of directly mapping specific terms to translations (which requires extensive registration), the system uses substitute terms as a intermediary layer that simplifies the registration process while maintaining translation accuracy.
2Ease of operation
If the translation device replaces specific terms with substitute terms, then the need for extensive term registration is reduced, but the translation accuracy may deteriorate if the substitute term translation does not match the original meaning
Solution Approach 1:
The system implements a feedback mechanism where the translation result is processed in reverse: after translation, the substitute terms in the translated text are replaced back with the original specific terms. This feedback loop ensures that the final translation maintains accuracy by restoring the original term semantics while benefiting from the simplified translation process.
Solution Approach 2:
The patent temporarily discards the original specific terms by replacing them with substitute terms during the translation process, then recovers the original terms by replacing the substitute terms back with the specific terms in the final translation output. This discard-recover cycle enables simplified processing while preserving translation accuracy.
3Adaptability or versatility
If the translation device uses a large vocabulary database to handle unfamiliar words, then translation coverage is improved, but the device size and data storage requirements increase
Solution Approach 1:
The patent extracts only the necessary substitution rules from the full vocabulary database - specifically, the mappings between specific terms and their substitute terms. This extraction approach allows the system to handle unfamiliar and specific terms without storing complete translation entries for all possible terms, significantly reducing data storage requirements while maintaining translation coverage.
Solution Approach 2:
The patent segments the translation task into two distinct phases: term replacement (using minimal substitution rules) and translation execution (using standard translation processes). This segmentation allows the system to handle specific and unfamiliar terms through replacement without requiring a comprehensive vocabulary database, thereby reducing storage requirements while maintaining versatility.
Data Source
AI summary
A storage unit stores a target term, a substitute term, a substitute translated term, and a representative term. The substitute translated term is a translation of the substitute term and is expressed in a second language. The representative term indicates a type of the target term and is expressed in the second language. A communication unit acquires a provisional translation that is a translation of a processed sentence from a first external device that has a translation function. When the storage unit does not store a target translated term that is a translation of the target term, a controller replaces the substitute translated term contained in the provisional translation with the representative term to generate a second display-purpose translated sentence, and then causes a display unit to display the second display-purpose translated sentence.
