Content-based filtering techniques are recommendation algorithms that suggest items to users based on the attributes and features of the items themselves. They analyze a user's past preferences and compare item content (such as keywords, categories, or characteristics) to generate personalized recommendations, enabling systems to tailor suggestions closely aligned with individual user tastes.
