Systems and methods are disclosed for generating an expanded user segment based on a target segment of users associated with a specified target feature. In one implementation, a method is provided that includes receiving information about online activity by a set of users, the information including a unique user ID associated with each of the set of users; extracting from the received information, data about the set of users who are associated with the specified target feature; specifying one or more independent features relevant to a user association with the specified target feature; building a model that represents the probability of any user being associated with the specified target feature, based on the extracted data and the independent features; and using the model to score a network population of users relative to the specified feature, based on information received about online activity by the network population of users.
