Recommender system

As explained in First-Party Data Activation

A software system that predicts and presents items, content, or actions likely to be relevant to an individual.

A recommender system predicts and presents items, content, or actions likely to matter to an individual. It converts customer insights into personalized experiences across channels, balancing relevance with privacy, transparency, consent, and user control. section 2.3.4

Design priorities include:

• Use collaborative or content-based filtering to personalize suggestions without collecting excessive personal data. section 2.3.4
• Explain how AI and user data shape personalization, and provide preference controls including opt-out. section 2.3.4
• Connect recommendations to email, social media, search, display advertising, and other customer-experience channels. section 2.3.4

How First-Party Data Activation covers it

How deep it goes

Explains filtering approaches, privacy practices, transparency, and consent, but not implementation mechanics.

Examples

Uses personalized suggestions, contextual targeting, multi-channel campaigns, and differential privacy in A/B testing.

What it assumes

Assumes clean data and addressed privacy concerns while teaching consent, transparency, and privacy-preserving personalization.

What you can do after

Apply it via collaborative or content-based filtering to deliver relevant suggestions while limiting unnecessary personal-data collection.

How it connects

Connects personalization engines, collaborative filtering, content-based filtering, customer experience technologies, and privacy-preserving analytics.
