Solution Overview

Problem

Existing community evaluation methods lack objective and quantitative indices to assess the impact of specific activities on community activation, particularly in real-world regions, and do not consider interactions between network and real-world communities.

Innovation Solution

A community evaluation system that constructs an effect model using activity and communication history data to evaluate the impact of specific activities on community activation, utilizing a storage unit, effect model construction, and evaluation units to quantify the connection and communication effects between communities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If subjective evaluation methods like questionnaires are used to assess community activation, then ease of operation is improved, but measurement precision deteriorates

Engineering Contradiction:

Improveease of evaluationVSAvoidobjectivity of evaluation

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent replaces subjective questionnaire-based evaluation with objective automated evaluation using information processing systems that analyze communication history data, transaction data, and mobility data to generate quantitative community activation indices, thereby eliminating human bias while maintaining ease of operation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an information processing device as an intermediary that objectively measures community activation through multiple data sources (communication history, transaction records, mobility patterns) and calculates composite indices, serving as a neutral mediator between raw data and evaluation results

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If only single-point evaluation is performed, then device complexity is reduced, but measurement precision deteriorates due to inability to capture continuous community growth

Engineering Contradiction:

Improvesimplicity of evaluation systemVSAvoidcontinuity of evaluation

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent implements continuous evaluation by automatically collecting and analyzing communication history data, transaction data, and mobility data over time periods, calculating community activation indices at multiple time points to capture the dynamic growth and changes in community activation rather than single-point snapshots

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent pre-establishes evaluation models and data collection frameworks that automatically process multiple data sources and calculate activation indices continuously, preparing the evaluation system in advance to capture community dynamics without requiring complex manual intervention at each evaluation point

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If evaluation focuses only on network community communication, then measurement precision for digital interaction is improved, but object-affected harmful factors increase due to neglect of real-world community impact

Engineering Contradiction:

Improveprecision of network interaction measurementVSAvoiddisconnection from real-world impact

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent merges evaluation of network community communication with real-world community activation by integrating analysis of communication history data with transaction data and mobility data, calculating how network interactions translate into real-world community activities and measuring the combined effect rather than treating them separately

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent establishes feedback mechanisms that measure how communication in network communities translates into activation of real-world communities, using the calculated indices to provide feedback on the effectiveness of online-offline connectivity and adjust evaluation models accordingly

Inventive Principle:

Principle #23Feedback

AI summary

A community evaluation system includes: effect model construction units and that construct, based on activity information data, history data, and communication history data, an effect model indicating a process in which a specific activity of a first community is reflected in communication in a network community and the communication in the network community is reflected in an activity of a second community; and an effect model evaluation unit that calculates an evaluation value of the process in the effect model, based on a size and a delay of a connection between the specific activity of the first community and the communication in the network community, and a size and a delay of a connection between the communication in the network community and the activity of the second community.
