Solution Overview

Problem

Conventional fixed-phrase translation systems face challenges in matching input sentences with pre-defined fixed phrases, resulting in insufficient translation accuracy.

Innovation Solution

A translation device that replaces terms of a predetermined type in the input text data with parameters, generates corresponding replacement data, and then replaces these parameters with translated terms in the target language, improving accuracy through weighting and similarity calculations based on scene-specific example sentence sets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional fixed-phrase translation is used, then translation speed is improved, but translation accuracy deteriorates due to difficulty in matching input sentences with fixed phrases

Engineering Contradiction:

Improvetranslation speedVSAvoidtranslation accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The patent segments the translation process into distinct phases: parameter replacement phase (replacing terms of predetermined types with parameters) and translation phase (translating the parameterized text). This segmentation allows the system to handle variable terms systematically while maintaining fixed-phrase matching efficiency, thereby improving both translation speed and accuracy simultaneously

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies parameter changes by replacing specific terms (of predetermined types) with parameters before performing fixed-phrase matching. This transformation enables the system to handle variations in input text while maintaining compatibility with pre-prepared fixed phrases, resolving the contradiction between translation speed and accuracy

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If the search range of example sentences is widened to improve matching, then translation accuracy may improve, but processing time increases

Engineering Contradiction:

Improvematching accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs parameter replacement as a preliminary action before the translation and matching processes. By pre-processing the input text to replace variable terms with parameters, the system narrows down the effective search space for fixed-phrase matching, thereby maintaining high accuracy while reducing processing time

Inventive Principle:

Principle #10Preliminary action

AI summary

A translation device includes an input unit and a controller. The input unit obtains first text data in a first language. The controller generates second text data in a second language that is a translation of the first text data. The controller further generates first replacement data by replacing a first term, of a predetermined type, contained in the first text data by a parameter, obtains second replacement data, in the second language, corresponding to the first replacement data, and generates the second text data by replacing the parameter contained in the second replacement data by a second term in the second language that is a translation of the first term.
