Content-based recommender
A content-based recommender suggests items whose features resemble those of items matching a user’s interests or prior interactions.
AI-Powered Search
A content-based recommendation is a recommendation generated by comparing attributes or features of users or items and suggesting entities with similar attributes.
- How it is used
- Ranks jobs or related products by matching user and item attributes, including categories and descriptions.
- How deep it goes
- Defines user-item and item-item matching and works through an SKG-generated search query, without specifying a general attribute-weighting algorithm.
- Examples
- Uses job-profile matching, laundry-product suggestions, and a Star Wars document converted into a boosted search query.
- What you can do after
- Build it from scratch as a scored-phrase search query using an SKG and a search collection to retrieve related documents.

The Art of AI Product Development
Content-based filtering recommends items whose attributes match the characteristics of items a user has previously preferred or interacted with.
- How it is used
- Personalizes product discovery by matching item attributes to a user’s previous interactions.
- How deep it goes
- Explains attribute matching, cold-start value, hybrid use, and context awareness without detailing implementation internals.
- Examples
- Uses black boots, unfamiliar brands, bohemian clothing, seasonal products, and mobile quick buys as recommendation examples.
- What you can do after
- Evaluate/understand how product attributes and early interactions support personalized recommendations and hybrid systems.

First-Party Data Activation
A recommendation technique that suggests items by comparing their attributes with the attributes of items a user has previously engaged with.
- How it is used
- Deploys recommendation systems within privacy-centric engagement and activation to tailor suggestions across channels.
- How deep it goes
- Defines content-based filtering as a privacy-preserving personalization option but does not detail its algorithmic implementation.
- Examples
- Uses personalized suggestions, tailored messaging, content, and experiences as application examples.
- What you can do after
- Apply it to personalize suggestions while minimizing excessive personal-data collection and preserving user control.
