Chatbots and conversational interfaces: Three domains of use

The natural language, in its oral or textual form, represents the main medium for communicating between human beings. Over time, technological advances have provided new means and tools through which human beings can express themselves and communicate with each other, without altering the original mode of interaction. In recent years, the search for new forms of interaction between users and systems has led to the diffusion of a new possible communication method that exploits a conversational approach based on natural language, which is referred to by using the term chatbot. This paper aims at exploring new chatbot-based conversational interfaces that allow users to exploit the most used interaction strategies by human beings, that is the natural language. Among the many possible application domains, this paper focuses on the introduction of a chatbot for supporting users in interacting with services for public administration (PA), health and wellbeing and home automation.
