Solution Overview

Problem

Conventional response devices struggle to form satisfactory responses when encountering unknown words or multiple dissimilar designations for the same person, leading to unsatisfactory replies.

Innovation Solution

A response device that detects related terms or designations by analyzing shared words in context, using a detection section to identify known words associated with unknown terms and forming responses based on these related terms or designations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional techniques are used to form response sentences, then the device can operate with simple word matching, but it fails to handle unknown words and multiple designations properly

Engineering Contradiction:

Improveability to handle unknown words and multiple designationsVSAvoidcomplexity of word analysis and relation detection

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a database as an intermediary component that stores relationships between words and their designations. This database mediates between the input sentence analysis and the response generation, enabling the system to handle unknown words and multiple designations without significantly increasing the complexity of the core processing logic. The database acts as a knowledge base that resolves ambiguities through pre-stored relational information.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent performs preliminary action by pre-processing and storing word-designation relationships in a database before actual response generation. This allows the system to quickly query and retrieve appropriate designations during operation, avoiding complex real-time analysis while maintaining high adaptability to various word forms and unknown terms.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If the device uses simple word association, then the response generation is fast, but it cannot recognize shared meanings between unknown words and known words

Engineering Contradiction:

Improveprecision of word meaning recognitionVSAvoidspeed of response sentence formation

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent pre-computes and stores word-designation relationships in a database, allowing the system to perform precise meaning recognition through quick database queries rather than complex real-time analysis. This preliminary preparation enables both high precision in recognizing shared meanings and maintained productivity in response generation speed.

Inventive Principle:

Principle #10Preliminary action

AI summary

A response sentence that is satisfactory to a user is formed. A response device (1) includes: a related term searching section (13) configured to, in a case where an input sentence contains an unknown word, detect a related term, which is a known word that shares, with the unknown word, at least one shared word; and a response sentence forming section (16) configured to form the response sentence whose content is related to the related term that has been detected by the related term searching section (13).
