Solution Overview

Problem

Japanese language complexity, with its multiple character sets (hiragana, katakana, and kanji), poses challenges for computer-implemented natural language interpretation, as direct comparison of character sequences fails to determine if they represent the same meaning, leading to cumbersome manual interventions for context-based word transformation and matching.

Innovation Solution

A neural network processing method that interprets Japanese characters by using multiple learning layers to analyze characters in both their received order and reverse order, providing alphabet representations for semantical meanings, enabling automated contextual interpretation and transformation of Japanese text into Latin alphabet representations for comparison.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If direct character comparison of Japanese character sequences is used, then the comparison process is simple, but it fails to determine whether different character sets represent the same meaning

Engineering Contradiction:
Improveaccuracy of meaning determinationVSAvoidcomplexity of processing system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary system comprising character set identification module, meaning extraction module, and comparison module. This intermediary processing layer translates Japanese characters from different character sets (hiragana, katakana, kanji) into unified meaning representations, enabling accurate semantic comparison while managing system complexity through modular design

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If manual intervention is provided for context-based word transformation, then interpretation accuracy improves, but processing time and operational complexity increase

Engineering Contradiction:
Improveinterpretation accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements self-service through automated context-based interpretation where the system automatically identifies character sets, extracts meanings, and performs word transformations without manual intervention. The neural network components and context analysis modules enable the system to autonomously resolve ambiguous Japanese words by analyzing surrounding context, eliminating the need for human operators while maintaining high interpretation accuracy

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple character sets (hiragana, katakana, kanji) are supported, then language coverage improves, but system complexity and processing difficulty increase

Engineering Contradiction:
Improvecharacter set coverageVSAvoidprocessing system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the processing of multiple Japanese character sets into distinct modular components: a character set identification module that detects which character set is being used, a meaning extraction module specific to each character set type, and a unified comparison module. This segmentation allows the system to handle hiragana, katakana, and kanji separately through specialized sub-routines while presenting a unified interface, thereby supporting multiple character sets without proportionally increasing overall system complexity

Inventive Principle:
Principle #1Segmentation

AI summary

Methods, systems, and computer-readable storage media for contextual interpretation of a Japanese word are provided. A first set of characters representing Japanese words is received. The first set of characters are received is input to a neural network. The neural network is trained to processes characters based on bi-directional context interpretation. The first set of characters is processed by the neural network through a plurality of learning layers that process the first set of characters in an order of the first set of characters and in a reverse order to determine semantical meanings of the characters in the first set of characters. An alphabet representation of at least one character of the first set of characters representing a Japanese word is output. The alphabet representation corresponds to a semantical meaning of the at least one character within the first set of characters.
