Solution Overview

Problem

Existing information processing systems struggle to effectively convert text from image data into formats suitable for individual users based on their characteristics, such as language, department, or age, which can lead to text that is not easily understood by the intended user.

Innovation Solution

The system includes circuitry that controls the reading of image data, acquires user characteristic information, and inputs instructions to a large language model to perform conversion processing, such as summarization or translation, ensuring the output is suitable for the user's characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If text is extracted from image data using conventional methods, then text extraction is achieved, but the converted text is not suitable for individual user characteristics

Engineering Contradiction:
Improveadaptability to user characteristicsVSAvoidease of understanding for user
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary acquisition of user characteristic information (such as language preferences, department, age) before conducting the text conversion. This allows the large language model to be pre-configured with user-specific parameters, ensuring that the converted text is tailored to the user's comprehension level and preferences from the outset, rather than requiring post-processing adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system applies different conversion parameters and processing approaches based on specific user characteristics. For example, text for younger users may use simpler vocabulary and explanations, while text for specialized departments may include domain-specific terminology. Each user receives customized text quality appropriate to their individual profile rather than a uniform conversion approach.

Inventive Principle:
Principle #3Local quality

2Productivity

If conventional text conversion is performed without considering user characteristics, then conversion processing is completed, but comprehension by the intended user is reduced

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidcomprehension reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system dynamically adjusts conversion parameters such as language style, level of detail, terminology complexity, and sentence structure based on user characteristic information. The large language model receives modified prompts that incorporate user attributes, causing the output text parameters to automatically adapt to the target user's comprehension capabilities, thereby maintaining both efficiency and reliability.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a large language model is used with user characteristic information, then text conversion suitable for user characteristics is achieved, but system complexity increases

Engineering Contradiction:
Improvecustomization capabilityVSAvoidsystem structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system introduces an intermediary information processing layer that receives user characteristic information and translates it into appropriate prompts for the large language model. This intermediary layer acts as a mediator between the raw user data and the AI model, organizing and formatting the characteristics into structured instructions that the model can effectively process, thereby managing system complexity while maintaining high adaptability.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An information processing system includes circuitry. The circuitry controls reading of image data from a document according to an instruction from a user. The circuitry acquires characteristic information of the user. The circuitry receives, from the user, information indicating conversion processing to be performed on text included in the image data. The circuitry extracts the text from the image data. The circuitry inputs, to a large language model, information including an instruction instructing that the conversion processing is to be performed on the text and that a result of the conversion processing is to be suitable for a person corresponding to the characteristic information. The circuitry acquires a conversion result that is output by the large language model. The circuitry outputs the conversion result.
