Query: Do You See What I See? Capabilities and Limits of Automated Multimedia
  Content Analysis   The ever-increasing amount of user-generated content online has led, in
recent years, to an expansion in research and investment in automated content
analysis tools. Scrutiny of automated content analysis has accelerated during
the COVID-19 pandemic, as social networking services have placed a greater
reliance on these tools due to concerns about health risks to their moderation
staff from in-person work. At the same time, there are important policy debates
around the world about how to improve content moderation while protecting free
expression and privacy. In order to advance these debates, we need to
understand the potential role of automated content analysis tools.
  This paper explains the capabilities and limitations of tools for analyzing
online multimedia content and highlights the potential risks of using these
tools at scale without accounting for their limitations. It focuses on two main
categories of tools: matching models and computer prediction models. Matching
models include cryptographic and perceptual hashing, which compare
user-generated content with existing and known content. Predictive models
(including computer vision and computer audition) are machine learning
techniques that aim to identify characteristics of new or previously unknown
content.
