Solution Overview

Problem

Existing information processing systems struggle to set customizable extraction items for generating minutes from communication content, resulting in uniform summaries despite varying meeting content.

Innovation Solution

An information processing system utilizing a large-scale language model (LLM) to analyze communication content, allowing customizable extraction items and generating business negotiation and analysis reports based on these items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional speech recognition and summarization techniques are used, then meeting content can be processed and minutes can be generated, but extraction items cannot be customized and all meetings produce uniform summaries

Engineering Contradiction:
Improvecustomizability of extraction itemsVSAvoidsystem complexity for customization
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically adjusts extraction items based on user input and meeting context. The extraction items are not fixed but can be modified and customized for different meeting types and user needs, allowing the system to adapt its behavior rather than following a static configuration

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system allows changing parameters of the extraction process by accepting user-defined extraction items. Different meeting scenarios can specify different extraction parameters (such as focusing on decisions, action items, or specific topics), enabling flexible customization without redesigning the entire system

Inventive Principle:
Principle #35Parameter changes

2Loss of information

If fixed extraction items are used for all meetings, then the system is simple to operate, but the extraction results are uniform and do not reflect specific meeting requirements

Engineering Contradiction:
Improveloss of specific meeting insightsVSAvoidease of setting extraction items
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system enables users to self-configure extraction items based on their specific meeting needs. Users can independently select and define what information to extract without requiring complex system administration or predefined templates, making the customization process simple and intuitive

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system maintains a universal framework that can handle multiple meeting types and extraction requirements through a single configurable interface. The same core processing engine serves diverse extraction needs by accepting different extraction item specifications, eliminating the need for separate systems for different meeting scenarios

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Measurement precision

If detailed customization of extraction items is enabled, then tailored summaries can be generated, but the operation complexity increases for users

Engineering Contradiction:
Improveprecision of extraction resultsVSAvoidcomplexity of extraction item configuration
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary processing of meeting content to identify potential extraction candidates before final extraction. This preliminary analysis prepares the data structure and identifies key elements, reducing the complexity of the actual extraction configuration while maintaining high precision results

Inventive Principle:
Principle #10Preliminary action
