Content filtering

As explained in Introduction to Generative AI, Second Edition

Content moderation is the review, ranking, restriction, or removal of user-generated or algorithmically generated content under defined policies.

Content moderation handles content under defined policies. In AI safety, it can involve people labeling unsafe examples to help train systems that detect or respond to harmful content. section 3.8

That protection has human costs: reviewing hate speech, abuse, and violence can be traumatic, and outsourced moderators may lack adequate pay and workplace protections. AI feedback may reduce reliance on manual review, but output filtering alone may not be enough as systems become more autonomous and context-aware. section 3.8 section 10.5

Moderation also raises governance questions. The European Union’s Digital Services Act requires covered platforms to assess risks, describe mitigation, and undergo audits; its transparency requirements include algorithmic accountability and content moderation. section 10.30

How Introduction to Generative AI, Second Edition covers it

How deep it goes
Describes labeling, safety training, labor costs, and regulatory transparency, but gives no implementation procedure.
Examples
Illustrates toxic-content detection trained with labeled examples and platform risk mitigation for disinformation recommendations.
What you can do after
Evaluate how moderation safeguards depend on human labor and why output filtering may not address broader system behavior.
How it connects
Links moderation to supervised fine-tuning, reinforcement learning from human feedback, AI feedback, and the Digital Services Act.
