Solution Overview

Problem

Existing translation technologies face low accuracy when translating polysemous words due to their multiple meanings, leading to errors in translation processes.

Innovation Solution

A method and apparatus that identify polysemous words in source language text, inquire related words corresponding to each interpretation, determine a target interpretation based on context, and translate the polysemy into the appropriate meaning, utilizing a polysemy library and corpus analysis to ensure accurate translation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If translation machines use standard translation algorithms to translate polysemous words, then translation speed is improved, but translation accuracy deteriorates due to multiple meanings causing errors

Engineering Contradiction:
Improvetranslation speedVSAvoidtranslation accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The system performs preliminary action by building a polysemy library that pre-stores multiple interpretations and related words for polysemous vocabularies before the actual translation process. When translating, the system queries this pre-built library to quickly retrieve candidate meanings and their associated related words, enabling fast disambiguation without sacrificing accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary mechanism - a polysemy library containing related words for each interpretation - that mediates between the source text and target translation. By querying related words from this intermediary library, the system determines the correct interpretation of polysemous words, thereby improving translation accuracy while maintaining efficiency through pre-organized data structures.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If translators manually translate polysemous words to ensure accuracy, then translation accuracy is improved, but translation efficiency deteriorates due to time-consuming processes

Engineering Contradiction:
Improvetranslation accuracyVSAvoidtranslation efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The system implements self-service by automatically querying the polysemy library and determining the correct interpretation of polysemous words without requiring manual translator intervention. The machine independently analyzes related words, determines target interpretations, and completes translations autonomously, thereby maintaining high accuracy while dramatically improving translation efficiency.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback mechanisms by analyzing the presence or absence of related words in the source text to determine the correct interpretation of polysemous words. The translation system queries the polysemy library, receives feedback about which related words are present in the context, and uses this feedback to select the appropriate target interpretation, ensuring accuracy without manual intervention.

Inventive Principle:
Principle #23Feedback
