Solution Overview

Problem

The accuracy of device recommendation using collaborative filtering is lowered unless the connection relation required for the recommendation coincides with the existing connection relation among devices.

Innovation Solution

An information processing apparatus that analyzes device connection information, extracts pairs of devices with common direct connection destinations, and updates the connection information to reflect these relationships, thereby enhancing the accuracy of device recommendations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If collaborative filtering is used for device recommendation, then device selection can be assisted, but recommendation accuracy is lowered unless connection relation coincides with existing connection relation

Engineering Contradiction:

Improverecommendation accuracyVSAvoidconnection relation flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary analysis of device connection information before recommendation to extract implicit connection relations. By pre-processing the connection data to identify devices with common direct connection destinations, the system prepares the recommendation foundation in advance, ensuring both accuracy and adaptability when performing actual recommendations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary processing layer that analyzes device connection information and extracts implicit relationships. This intermediary layer bridges the gap between existing connection data and recommendation requirements, transforming raw connection information into actionable recommendation insights without requiring exact matches between connection relations.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If device connection information is updated to include extracted pairs, then recommendation accuracy increases, but data processing complexity increases

Engineering Contradiction:

Improverecommendation accuracyVSAvoiddata processing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the device connection information processing into distinct stages: extraction of devices with common direct connection destinations, identification of implicit connection pairs, and update of connection information. This segmentation simplifies the overall complexity by breaking down the processing task into manageable, sequential steps that can be implemented and maintained more easily.

Inventive Principle:

Principle #1Segmentation

AI summary

An extraction unit (101) analyzes device connection information in which a device being a direct connection destination of each device of a plurality of connected devices is described and extracts, among two or more devices whose direct connection destination is common, a pair of devices each of which is not described as a device being a direct connection destination of the other device in the device connection information. An update unit (102) updates the device connection information so that the device connection information describes that each one of the pair of devices extracted by the extraction unit (101) is a device being a direct connection destination of the other device.
