The Technological Gap Between Virtual Assistants and Recommendation Systems.

Virtual assistants, also known as intelligent conversational systems such as Googleu0027s Virtual Assistant and Appleu0027s Siri, interact with human-like responses to usersu0027 queries and finish specific tasks. Meanwhile, existing recommendation technologies model usersu0027 evolving, diverse and multi-aspect preferences to generate recommendations in various domains/applications, aiming to improve the citizensu0027 daily life by making suggestions. The repertoire of actions is no longer limited to the one-shot presentation of recommendation lists, which can be insufficient when the goal is to offer decision support for the user, by quickly adapting to his/her preferences through conversations. Such an interactive mechanism is currently missing from recommendation systems. This article sheds light on the gap between virtual assistants and recommendation systems in terms of different technological aspects. In particular, we try to answer the most fundamental research question, which are the missing technological factors to implement a personalized intelligent conversational agent for producing accurate recommendations while taking into account how users behave under different conditions. The goal is, instead of adapting humans to machines, to actually provide users with better recommendation services so that machines will be adapted to humans in daily life.
