Users-for-item recommendations retrieve the set of users who have interacted with an item, weighted by the number of interactions. This can be useful for community-driven use cases or for marketing campaigns. For example, on your organization’s intranet, clicking a search result could display the item plus a list of colleagues who have interacted with the same item.

This is one type of [collaborative recommendation](/docs/5/fusion/getting-data-out/query-enhancement/recommendations/recommendation-methods#content-based-vs-collaborative-recommendations).
