Content Evaluation via Creation Process Feature Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content evaluation methods struggle to accurately assess the authenticity and creation process of digital content, particularly with the rise of advanced machine learning models that can generate sophisticated imitations, as they rely solely on the finished product's content without considering the creation process.
Innovation Solution
A content evaluation system that includes a user device and a server device, which calculates state features and operation features by analyzing the creation process through a series of operations, generating a time series of state features and determining the amount of change between operations to evaluate the content's authenticity and creation steps.

Engineering Contradiction Analysis
1Measurement precision
If content evaluation is performed by merely using the contents of drawing of a finished product, then the evaluation process is simple and quick, but the evaluation detail and accuracy are insufficient
Solution Approach 1:
The evaluation process is segmented into multiple independent feature extraction components: state feature extraction from drawing snapshots, operation feature extraction from operation logs, and meta feature extraction from creation metadata. Each segment processes specific aspects of the creation process separately, then results are integrated to achieve comprehensive evaluation with high accuracy without overwhelming system complexity
Solution Approach 2:
The evaluation transitions from a single-dimension approach (only analyzing finished product content) to a multi-dimensional approach by incorporating temporal dimension (time series of drawing states), operational dimension (sequence of operations), and contextual dimension (meta information). This dimensional expansion enables elaborate evaluation while maintaining manageable complexity through structured feature organization
2Productivity
If machine learning models generate imitation content automatically, then content creation efficiency is improved, but content authenticity becomes difficult to determine
Solution Approach 1:
The system performs preliminary action by capturing and preserving the complete creation process data (drawing snapshots, operation logs, meta information) during the content creation phase. This preliminary data collection enables subsequent authenticity verification without interfering with the efficient content creation process, allowing rapid generation while maintaining verifiable authenticity records
Solution Approach 2:
The evaluation system provides feedback by analyzing creation process features and generating authenticity assessments. This feedback mechanism enables automated detection of machine-generated imitations by identifying characteristic patterns in the creation process, thereby maintaining reliability even as productivity increases through automated content generation

AI summary
Provided is a content evaluation device including a processor and a memory storing a program that, when executed by the processor, causes the content evaluation device to: calculate a state feature relating to a drawing state in a creation period from a start timing to an end timing of creation of content, and generate a picture-print that is a set or locus of points on a feature space that represents the state feature.
