A computer-implemented service analyzes collected data reflective of actions of users of an interactive system to identify items that are significantly more popular in specific user communities than in a general user population. The communities may, for example, include email-based communities (e.g., all users with email addresses associated with a particular company or other organization), shipping address based communities (e.g., all users with shipping addresses in Seattle), and/or communities based on other types of user attributes. The results of the analysis may be exposed to users to assist users in making item selection decisions, and/or may be used to provide item recommendations to users.

What is claimed is: 1. A computer-implemented data mining method, comprising:storing, in an electronic data repository, user activity data associated with each of a plurality of users of an online system that provides access to an electronic catalog, said user activity data reflecting user-generated events associated with particular items represented in the electronic catalog;programmatically identifying, among the plurality of users, a subset of users whose email addresses are associated with a particular organization;programmatically analyzing the user activity data associated with the plurality of users, including the subset of users, by execution of code by a computer processor, to identify a set of items that have experienced significantly higher levels of user activity among the subset of users than among the plurality of users; andcreating, in computer storage, an association between the organization and the identified set of items.
