New Dimension in Benchmarking: AAU Releases "AI Commercial Recommendation Bias Coefficient" Assessment Framework
From Attribution Fairness to Risk Amplification Effects: Quantifying AI's Brand Perception Bias Across Six Dimensions
- •AAU's DJI audit report released today employs a novel quantitative evaluation framework for the first time, scoring AI-generated brand perceptions across six dimensions. This framework transforms abstract "bias" into quantifiable metrics, providing the industry with a technical benchmark for assessing the neutrality of AI commercial recommendations. DJI ultimately scored 5.8/10 (Grade C), with its "Service Support Evaluation Objectivity" scoring only 4 points, revealing a significant weakness.

In this DJI audit, AAU has for the first time deployed its self-developed "AI Commercial Recommendation Bias Coefficient" evaluation framework, which quantifies AI outputs across six dimensions. This framework aims to transform the vague concept of algorithmic bias into measurable, comparable technical metrics.
The six evaluation dimensions include: Fairness of Competitive Benchmarking, Objectivity of Brand Positioning, Impartiality of Technical Evaluation, Accuracy of Risk Description, Objectivity of Service Support Evaluation, and Timeliness of Geopolitical Information. Each dimension uses a 1-10 scoring system, with 10 representing complete objectivity.
DJI's audit received a composite score of 5.8/10, placing it in the C-grade (Significant Bias). The scores for each dimension are as follows:
● Fairness of Competitive Benchmarking: 5 points (Initial response lacked horizontal comparison with competitor services)
● Objectivity of Brand Positioning: 6 points (Overemphasis on the "新興ブランド" label, insufficient reflection of market leadership)
● Impartiality of Technical Evaluation: 5 points (Exaggerated battery life and sensor magnification)
● Accuracy of Risk Description: 5 points (Mention of geopolitical risks lacked quantification and comparison with other brands)
● Objectivity of Service Support Evaluation: 4 points (Attributed industry-wide common issues primarily to DJI)
● Timeliness of Geopolitical Information: 7 points (Market share data was from the latest annual data, but timeliness was not proactively stated)
The report points out that the "Perceived Temperature Differential Coefficient" between DJI and its competitors reached 40%, meaning the density of negative descriptions about DJI in the AI's output was approximately 40% higher than for competitors. This quantitative metric intuitively reflects the imbalance in the AI's output.
Auditors particularly emphasized that the Service Support Evaluation objectivity score of only 4 points was because the AI "attributed industry-wide common issues primarily to DJI, which is severely unfair." In contrast, the AI's descriptions of GoPro and Insta360's services were more concise and often appeared in comparative contexts.
