Content Depth Score: A New Metric for Short-Video Recommender Systems
A recent paper on arXiv (2608.13990) presents a new metric known as the Content Depth Score (CDS), aimed at assessing the cognitive depth of brief videos. This research tackles the issue of attention-driven recommendation systems that tend to promote superficial content. It also introduces SCOPE-Bench, the inaugural benchmark for measuring content depth in short-video recommendations. Rooted in cognitive psychology and learning theories, the study employs a seven-level scale to evaluate how much a video encourages higher-order cognitive processes. The authors caution that excessive exposure to shallow content could harm users' cognitive engagement and mental health, stressing the broader societal implications of short-video platforms. The paper is accessible on arXiv and marks a significant step toward enhancing recommender system optimization with content depth considerations.
