Abstract: A method is provided in accordance with an aspect of the present disclosure. The method includes processing data related to a group of contacts, where the data includes at least one attribute related to each of the contacts. The method also includes defining the at least one attribute based on a probability distribution of a context in relation to attribute values of the at least one attribute for all contacts. The method further includes determining clusters of contacts based on the probability distribution of the context in relation to the attribute values of the at least one attribute for all contacts, and constructing a plurality of segments of similar contacts by using the clusters.

Abstract: A method is provided in accordance with an aspect of the present disclosure. The method includes obtaining at least one attribute of a contact, and obtaining context information related to a plurality of contexts, where each context is associated with a set of segments of contacts, a distance metric, and at least one promoted item. The method also includes, for each context in the plurality of contexts, determining a distance between the contact and the context by determining, using the distance metric associated with each context, a shortest distance between the contact and each of the segments associated with the context. The method further includes associating the contact with the at least one promoted item associated with the context having a shortest distance from the contact.
