Recommender Systems
AI systems that suggest content, products, or services to users based on analysis of preferences, behavior, and patterns.
Definition
Recommender Systems are AI-powered systems that analyze user data to suggest relevant content, products, services, or information. They are fundamental to social media, e-commerce, streaming services, and content platforms.
Regulatory Status: Recommender systems face varied regulatory treatment:
- EU AI Act: Generally not high-risk, but subject to transparency requirements under Article 50 when interacting with users
- EU DSA: Digital Services Act imposes significant obligations on recommender systems used by very large online platforms (VLOPs)
- Transparency: Platforms must explain main parameters and provide at least one non-profiling-based option
DSA Requirements for VLOPs (Article 27):
- Clear terms of service explaining recommender system parameters
- Disclosure of criteria for content ranking and recommendation
- User option to modify or disable personalization
- At least one option not based on profiling
Risk Concerns:
- Filter bubbles: Users exposed only to reinforcing viewpoints
- Amplification: Harmful or divisive content may get prioritized for engagement
- Manipulation: Potential for promoting commercial or political content
- Addiction: Designs optimizing for engagement over user wellbeing
