“…To begin with, personalization can be characterized based on a consumer engagement in communication, which allows to define several personalization types: pull personalization (when a customer explicitly requests personalization), passive personalization (still requires customer's action, but is more reliant on the company), push personalization (company provides personalization service directly to a customer without request from him/her) (Wedel, Kannan, 2016). Apart from that, authors suggest that personalization techniques can be divided into those establishing the feeling of personal communication (achieved through anthropomorphization) and those creating the sense of belongingness to the group and awareness of a customer preferences (achieved through recommendation systems) (Gogua & Smirnova, 2020). Anthropomorphization refers to such tools as chatbots, intelligent agents and conversation agents, while recommendation systems involve displaying the offers to a customer based on his previous searching history, actions of similar customers or the average preferences of a similar group (Gogua & Smirnova, 2020).…”
