Solution Overview

Problem

Current information processing systems lack an efficient method to determine relevance between electronic documents based on user interactions, such as document movements on a screen, which limits the ability to identify and output relevant documents.

Innovation Solution

An information processing apparatus that includes modules for receiving and detecting manipulations, extracting movement-related information, and determining document relevance by analyzing the location, distance, direction, and similarity of documents, using a manipulation history processing system to identify relevant documents based on user interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If document relevance is determined based on traditional search methods, then the system is simple to implement, but the ability to identify relevant documents based on user interactions is insufficient

Engineering Contradiction:

Improvedocument relevance determination accuracyVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical search methods with a manipulation history-based system that tracks user interactions. The manipulation history processing unit analyzes movement manipulations and spatial relationships to determine document relevance, substituting conventional search algorithms with interaction-pattern-based relevance determination.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces manipulation history as an intermediary between user actions and document relevance determination. The manipulation history processing unit acts as a mediator that processes movement manipulations and spatial relationships to generate relevance information, which then influences document retrieval and display.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the system analyzes user interactions to determine document relevance, then document retrieval efficiency is improved, but the complexity of processing manipulation history increases

Engineering Contradiction:

Improvedocument retrieval efficiencyVSAvoidmanipulation history processing complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the manipulation history processing into distinct functional units: the manipulation history processing unit that analyzes movement manipulations, the spatial relationship determination unit that calculates distances and directions, and the relevance determination unit that synthesizes this information. This segmentation reduces overall processing complexity by dividing the task into manageable components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary processing of manipulation histories and spatial relationships before final relevance determination. The manipulation history processing unit pre-processes movement data and the spatial relationship determination unit pre-calculates distances and directions, so that when relevance determination is needed, the necessary information is already prepared and processed.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If the system extracts movement source and destination locations, then the ability to determine spatial relationships is improved, but the processing time increases

Engineering Contradiction:

Improvespatial relationship measurement precisionVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies partial action by extracting only the necessary spatial information (movement source location, movement destination location, distance, and direction) from the full manipulation history rather than processing every detail of user interaction. This selective extraction maintains measurement precision for the critical spatial relationships while reducing overall processing time.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

An information processing apparatus includes a reception unit that receives manipulation of a manipulator, which corresponds to an electronic document arranged on a screen, a detection unit that detects a manipulation related to a movement of the electronic document from the manipulation received using the reception unit, an extraction unit that extracts at least a location of a movement source, a location of a movement destination, a first electronic document which is a movement target electronic document, and a second electronic document which is an electronic document within a predetermined distance from the location of the movement destination based on the movement manipulation detected using the detection unit, and a relevant document determination unit that determines whether the second electronic document is relevant to the first electronic document based on information extracted using the extraction unit.
